摘要

TLDRChris, a food handler, explains that preventing food poisoning largely depends on addressing invisible organisms found everywhere. Key contamination culprits are cross-contamination, inadequate temperature control, and poor personal hygiene. Cross-contamination often happens through improper handling of raw and cooked foods. It highlights the importance of using separate cutting boards and ensuring all equipment and hands are sanitized. Understanding temperature zones is crucial; 5°C-60°C is the danger zone for bacterial growth, with the 2-hour/4-hour rule assisting in managing food out of refrigeration. Proper cooking and cooling procedures prevent bacteria proliferation. Handwashing remains vital in removing bacteria that typically cling to surfaces. Moreover, food handlers must not work if experiencing gastrointestinal symptoms due to high risk of bacterial exposure through food. It is the responsibility of handlers to ensure food remains safe for public consumption by maintaining good hygiene, preventing cross-contamination, and effectively controlling temperature.

    Chris introduces the importance of food handling and the happiness food brings. He explains that invisible microorganisms, some harmful, can cause food poisoning, which is a serious health risk. Handling food properly is crucial to avoid illness. He highlights that some foods can appear fine but still cause sickness due to bacteria.

  • 00:05:00 - 00:10:00

    Chris emphasizes the importance of preventing cross-contamination in food handling. He explains that having separate cutting boards and knives for raw meats and using sanitizers can minimize contamination risks. The focus is on maintaining cleanliness in the kitchen to reduce the chances of bugs contaminating food.

  • 00:10:00 - 00:15:00

    The video discusses temperature control as a key factor in preventing foodborne illnesses. Chris explains that bacteria can thrive in a 'danger zone' of temperatures and emphasizes the need to store food correctly. He introduces the "2-hour/4-hour rule" for managing the time food spends in this danger zone to prevent bacteria growth.

  • 00:15:00 - 00:20:00

    The video continues to stress the importance of temperature control, explaining that proper cooking and cooling are essential in killing harmful bacteria in foods. Timing and temperature management are vital in reducing risks, especially for potentially hazardous foods like meats and dairy-based dishes.

  • 00:20:00 - 00:25:00

    Personal hygiene is highlighted as crucial in preventing food contamination. Chris explains the importance of thorough hand washing and using designated basins to minimize bacteria transfer. Even when hands are washed, certain sicknesses require workers to stay home to prevent spreading diseases like Salmonella.

  • 00:25:00 - 00:30:00

    Chris stresses that despite proper hygiene, sick individuals must not handle food due to high contagion risk. When illness is suspected, the worker should inform a supervisor and avoid food handling. This separation is key to preventing contamination from infected persons to food. Legal obligations for reporting are noted.

  • 00:30:00 - 00:39:00

    Chris concludes by reaffirming the critical roles food handlers play in maintaining public health through safe food practices. The importance of continuous vigilance in applying the discussed principles of cross-contamination, temperature control, and personal hygiene is reiterated to ensure consumer safety.

    hi I'm Chris food is one of those things
  • 00:00:53
    in life that's both essential and
  • 00:00:56
    enjoyable here at Regency ta we pride
  • 00:01:00
    ourselves on providing great food that
  • 00:01:02
    makes people
  • 00:01:10
    happy every day in this state thousands
  • 00:01:13
    of people handle food that serve to the
  • 00:01:16
    public that means a lot of happy
  • 00:01:18
    customers every day of the
  • 00:01:21
    year but now and again people like Joe
  • 00:01:24
    get sick from something bad in the food
  • 00:01:26
    that us food handlers have prepared
  • 00:01:30
    that's something that should never
  • 00:01:33
    happen I thought I knew everything about
  • 00:01:35
    how to handle food properly but when I
  • 00:01:38
    was asked to check out what can go wrong
  • 00:01:41
    I got a few
  • 00:01:42
    surprises the problem is the things that
  • 00:01:45
    can cause people to get sick are
  • 00:01:47
    invisible to us now microscopic
  • 00:01:50
    organisms are everywhere we have them
  • 00:01:52
    all through our bodies the soils full of
  • 00:01:54
    them most of them are perfectly harmless
  • 00:01:57
    and many are good for us helping us to
  • 00:02:00
    digest our food for example but some are
  • 00:02:03
    very bad and can cause nasty diseases
  • 00:02:06
    such as tuberculosis pneumonia and food
  • 00:02:09
    poisoning which I've had and I do not
  • 00:02:12
    want to
  • 00:02:13
    repeat you should also remember that
  • 00:02:15
    people can die from food
  • 00:02:18
    poisoning one of the trickiest things
  • 00:02:20
    about this is that you often can't tell
  • 00:02:22
    when you're eating something bad simply
  • 00:02:25
    throwing out spoiled or moldy food won't
  • 00:02:27
    protect us when people people get sick
  • 00:02:31
    it's often from food that looks smells
  • 00:02:34
    and tastes just fine the type of bugs we
  • 00:02:37
    don't want a nice system can often be
  • 00:02:39
    found on raw meats before it's
  • 00:02:42
    cooked others can grow in food if it's
  • 00:02:45
    left out too
  • 00:02:47
    long and another type of bug is spread
  • 00:02:49
    by people who have a gastric
  • 00:02:55
    upset better pop one of these on you
  • 00:02:59
    can't see the drugs they're so
  • 00:03:00
    incredibly small but they exist all
  • 00:03:04
    right and they can cause big
  • 00:03:10
    problems though they can't be seen they
  • 00:03:13
    can be beaten it's not that hard but it
  • 00:03:16
    is a constant battle now the front line
  • 00:03:19
    in the defense against these bugs is you
  • 00:03:22
    and that
  • 00:03:36
    wherever you are the principles of
  • 00:03:38
    Defense are the same there are three
  • 00:03:40
    main areas where these bugs might take
  • 00:03:42
    advantage if we're not careful they are
  • 00:03:45
    cross-contamination temperature control
  • 00:03:47
    and personal hygiene let's start by
  • 00:03:50
    looking at
  • 00:03:52
    cross-contamination when Joe's case was
  • 00:03:54
    investigated the food poisoning was
  • 00:03:56
    traced to the C law he'd bought 4 days
  • 00:03:59
    before boy became
  • 00:04:01
    ill 2 hours before he bought it the
  • 00:04:04
    kitchen where the co slore was made was
  • 00:04:06
    flat out merely rinsing The Cutting
  • 00:04:09
    Board will prove to be Joe's
  • 00:04:11
    downfall no matter how well the food
  • 00:04:13
    handler washes his
  • 00:04:15
    hands or dries the board
  • 00:04:30
    and Joe was
  • 00:04:31
    doomed the bugs had already grasped
  • 00:04:34
    their opportunity 2 hours earlier all
  • 00:04:37
    raw meat especially raw poultry and aul
  • 00:04:39
    cuts has bugs on it many are harmless
  • 00:04:42
    but some are dangerous the presence of a
  • 00:04:45
    few really nasty ones is revealed with a
  • 00:04:48
    bug Cam and until cooked they remain a
  • 00:04:53
    danger now we can see why simply rinsing
  • 00:04:55
    and drying The Cutting Board wasn't good
  • 00:04:58
    enough
  • 00:05:00
    and how the bugs grab their
  • 00:05:02
    chance with this type of bug it doesn't
  • 00:05:05
    take many to cause
  • 00:05:08
    trouble when you use that bug cam it's
  • 00:05:11
    easy to see what went wrong you know
  • 00:05:13
    it's also easy to keep the bugs out in
  • 00:05:15
    the first place by keeping them separate
  • 00:05:18
    from your prepared foods the simplest
  • 00:05:21
    and best solution is to have a
  • 00:05:23
    completely separate board for raw meats
  • 00:05:26
    different colors help and of course you
  • 00:05:28
    should keep your knives separate too
  • 00:05:30
    however if you have to use a board
  • 00:05:32
    that's already been used for raw meat or
  • 00:05:34
    you're not sure what a board's been used
  • 00:05:37
    for then after washing it you'll need to
  • 00:05:40
    use either an antibacterial sanitizer or
  • 00:05:44
    a dishwasher that reaches at least 65°
  • 00:05:50
    C and remember our hands whenever they
  • 00:05:53
    come into contact with raw meat must be
  • 00:05:55
    washed thoroughly as always what we've
  • 00:05:58
    been talking about is stock stopping
  • 00:06:00
    contamination now microscopic bugs cause
  • 00:06:03
    the most serious contamination but
  • 00:06:05
    insects and dirt from animals can also
  • 00:06:08
    get into food so the kitchen's not for
  • 00:06:11
    them keep everything clean and the risk
  • 00:06:14
    of contamination goes right down wearing
  • 00:06:17
    clean clothing also helps it shows we
  • 00:06:20
    have the right
  • 00:06:21
    attitude and if you have a cut or a saw
  • 00:06:24
    it should be covered to stop it getting
  • 00:06:26
    infected and maybe contaminating the
  • 00:06:28
    food wash fruit and vegetables if
  • 00:06:30
    they're visibly dirty or if there's a
  • 00:06:32
    chance they've got insects or slugs on
  • 00:06:34
    them we can also contaminate the food if
  • 00:06:37
    we're sick but we'll talk more about
  • 00:06:39
    that in a minute the main thing to
  • 00:06:41
    remember is to keep the bugs separate
  • 00:06:43
    from the food to be eaten those bugs are
  • 00:06:45
    waiting for any slip UPS in the food
  • 00:06:47
    preparation chain when you receive Food
  • 00:06:51
    make sure it's been properly packaged or
  • 00:06:53
    covered during transport in the fridge
  • 00:06:56
    raw meat should be stored so that it
  • 00:06:58
    can't contact or drip onto other food
  • 00:07:01
    and keep it separate when it's on
  • 00:07:03
    display cooked meats must go on a clean
  • 00:07:06
    tray or board certainly never the same
  • 00:07:09
    thing that held the raw meat unless it's
  • 00:07:11
    been cleaned and sanitized or been in
  • 00:07:13
    the
  • 00:07:14
    dishwasher all food on display should be
  • 00:07:16
    wrapped or covered in some way and
  • 00:07:19
    unpackaged self-service food must be
  • 00:07:21
    supervised again there should be a
  • 00:07:24
    barrier to minimize possible
  • 00:07:25
    contamination between customers and the
  • 00:07:27
    food so keeping the bugs separate from
  • 00:07:31
    prepared food so they don't contaminate
  • 00:07:33
    it is the first step towards controlling
  • 00:07:35
    the bugs the second area we have to look
  • 00:07:38
    out for is temperature
  • 00:07:49
    control thank you
  • 00:08:14
    within 15 minutes Susan's friend was
  • 00:08:17
    also taken
  • 00:08:18
    ill this case begins earlier that same
  • 00:08:26
    day hey George what do I do fridge is
  • 00:08:29
    full oh just cover it up and leave it on
  • 00:08:32
    the bench has to be reheated
  • 00:08:53
    anyway that yellow stuff is bad news for
  • 00:08:56
    humans it's a toxin produced by the
  • 00:08:59
    bacteria Bia so what went wrong bacteria
  • 00:09:03
    can't survive above 75° so the boiling
  • 00:09:06
    that morning would have taken care of
  • 00:09:08
    them then it was covered during the day
  • 00:09:11
    so nothing could have got
  • 00:09:12
    in of course from the outside it looks
  • 00:09:15
    like nothing's going on but the tricky
  • 00:09:18
    little blighters left spores which are
  • 00:09:20
    like eggs and they can survive boiling
  • 00:09:23
    they hatched into bacteria that found
  • 00:09:25
    themselves living in a very nice piece
  • 00:09:27
    of real estate in a very in
  • 00:09:33
    climate with such nice conditions and
  • 00:09:36
    lots of time this sort of bacteria
  • 00:09:38
    starts to multiply like
  • 00:09:42
    mad by dinner time the rice was swarming
  • 00:09:45
    with millions of bacteria and they all
  • 00:09:48
    produced a toxin as they
  • 00:09:51
    grew while the bugs were killed during
  • 00:09:53
    reheating the toxin survived and that's
  • 00:09:56
    a poison for us if there's enough of it
  • 00:09:59
    and the moral of this story uh the
  • 00:10:02
    little blers can be very
  • 00:10:04
    tricky yeah but we also know how they
  • 00:10:08
    operate which means we can stop
  • 00:10:12
    them we know they like a nice moderate
  • 00:10:15
    temperature with plenty of food and
  • 00:10:17
    moisture to grow and enough time now
  • 00:10:20
    there will always be food we want to eat
  • 00:10:23
    that bacteria like to grow in we call
  • 00:10:25
    this potentially hazardous food and they
  • 00:10:28
    include a whole whole swag of things
  • 00:10:30
    including milk cream and custard cooked
  • 00:10:34
    food that has meat rice pasta eggs or
  • 00:10:36
    beans in it prepared salads and homemade
  • 00:10:40
    dressings like mayonnaise and any food
  • 00:10:42
    that contains these foods such as
  • 00:10:44
    sandwiches in other words a lot of the
  • 00:10:47
    food we handle is potentially hazardous
  • 00:10:50
    it doesn't include acidic food such as
  • 00:10:52
    jams or yogurt or dry food such as
  • 00:10:55
    biscuits or cakes except if they have
  • 00:10:58
    fresh cream or Custard in them what the
  • 00:11:01
    bugs are looking for is a moist place
  • 00:11:03
    with plenty of nutrients especially
  • 00:11:06
    protein if in doubt treat it as
  • 00:11:09
    potentially hazardous and you can always
  • 00:11:11
    check with your local environmental
  • 00:11:12
    health
  • 00:11:14
    officer the way to stop bacteria growing
  • 00:11:16
    on this sort of food is to watch
  • 00:11:18
    temperature and time in other words
  • 00:11:21
    temperature control the danger zone
  • 00:11:24
    where the bugs live is between 5 and 60°
  • 00:11:28
    C for below 5° the bugs or microbes
  • 00:11:31
    mostly stop
  • 00:11:33
    growing above 60 and they're usually
  • 00:11:36
    killed that's fine as far as it goes but
  • 00:11:39
    what about when you can't keep it under
  • 00:11:41
    temperature control like when it's on
  • 00:11:44
    display that's where time comes in the
  • 00:11:46
    sort of bacteria we're worried about
  • 00:11:48
    here needs time to multiply and it takes
  • 00:11:51
    a while for the numbers to build up to
  • 00:11:53
    where they become dangerous how long
  • 00:11:56
    well 4 hours is the cut off time after 4
  • 00:11:59
    4 hours in the danger zone cheuck it out
  • 00:12:02
    there's a handy rule called the 2hour 4H
  • 00:12:04
    hour rule say a meat and salad roll is
  • 00:12:07
    prepared at 12:00 p.m. it can stay at
  • 00:12:10
    room temperature until 400 p.m. then it
  • 00:12:13
    must be thrown
  • 00:12:14
    out if you want to keep the roll for
  • 00:12:17
    later on then you've got to put it in
  • 00:12:19
    the fridge by 2:00
  • 00:12:20
    p.m. and when you take it out again say
  • 00:12:23
    at 6:30 p.m. it must be used within the
  • 00:12:27
    next 2 hours which is a to of 4 hours
  • 00:12:30
    out of temperature control temperature
  • 00:12:33
    control applies right along the food
  • 00:12:35
    preparation chain once potentially
  • 00:12:38
    hazardous food is thored it should be
  • 00:12:40
    used as soon as possible or stored in
  • 00:12:42
    the fridge to keep it out of the danger
  • 00:12:45
    zone someone should always be there when
  • 00:12:47
    food is delivered especially potentially
  • 00:12:50
    hazardous food it's best if this food is
  • 00:12:52
    transported below 5 or above
  • 00:12:55
    60 however if it is transported in the
  • 00:12:58
    danger Zone then of course that time
  • 00:13:01
    then counts as part of the 4 hours
  • 00:13:03
    temperature and time the bugs can use
  • 00:13:06
    them if we get slack give them the right
  • 00:13:09
    conditions and they'll take advantage
  • 00:13:11
    every time but as we've seen we can also
  • 00:13:14
    use temperature in time to beat the bugs
  • 00:13:17
    we know about the temperature danger
  • 00:13:19
    zone and we have the 2hour 4H hour
  • 00:13:23
    rule temperature control also applies to
  • 00:13:26
    cooking and cooling the food
  • 00:13:30
    it sounds obvious but food must be
  • 00:13:33
    cooked thoroughly especially rolled
  • 00:13:35
    roasts patties and sausages bacteria
  • 00:13:38
    which naturally occurs on the surface
  • 00:13:40
    can end up in the middle of these types
  • 00:13:42
    of meats so no pink in the middle for
  • 00:13:45
    these
  • 00:13:46
    ones chicken must be cooked till the
  • 00:13:49
    juices run clear and always stir food in
  • 00:13:52
    a microwave to make sure it's heated
  • 00:13:54
    evenly if food has to be cooled after
  • 00:13:56
    cooking do it as quickly as possible aim
  • 00:13:59
    to get it down to 21° in 2 hours and
  • 00:14:02
    then down to 5° after a further 4 hours
  • 00:14:06
    you can put large amounts of cooked food
  • 00:14:08
    in Shallow containers to speed up the
  • 00:14:11
    cooling that's about it on the
  • 00:14:13
    temperature control front now the third
  • 00:14:16
    and final area where the little blers
  • 00:14:17
    look for opportunities is personal
  • 00:14:20
    hygiene and
  • 00:14:27
    cleanliness our hands are always picking
  • 00:14:29
    up microbes so they can easily transfer
  • 00:14:32
    them to
  • 00:14:34
    food thorough handwashing is one of the
  • 00:14:37
    most important ways to help prevent the
  • 00:14:39
    transfer of microbes soap helps to get
  • 00:14:42
    off the grease and fat drying off is
  • 00:14:45
    important there can be bugs in the
  • 00:14:47
    moisture left on your hands so a proper
  • 00:14:50
    hand wash is always the go before you
  • 00:14:52
    start handling food as we saw earlier
  • 00:14:56
    you must also wash your hands after
  • 00:14:58
    handling raw meat needs always use the
  • 00:15:00
    hand Basin that's meant just for hand
  • 00:15:02
    washing and of course after using the
  • 00:15:04
    toilet head straight for the hand
  • 00:15:07
    Basin and don't use your apron or tea
  • 00:15:10
    towel at these times to dry off you
  • 00:15:12
    could be transferring the little
  • 00:15:14
    blighters and they'll be there next time
  • 00:15:16
    you wipe your hands by the way if you
  • 00:15:19
    use disposable gloves you've got to
  • 00:15:21
    change them just as often as you'd wash
  • 00:15:23
    your hands hand washing is really common
  • 00:15:26
    sense and something you'll end up doing
  • 00:15:28
    a lot especially before handling food
  • 00:15:31
    and after touching raw meat or using the
  • 00:15:33
    toilet that'll really help in the fight
  • 00:15:35
    against the bugs but there's one time
  • 00:15:38
    even when you wash your hands perfectly
  • 00:15:40
    it won't be good
  • 00:15:54
    enough yep
  • 00:16:12
    upit think govern be it was found that
  • 00:16:16
    the bacteria causing young Katie such
  • 00:16:18
    distress was salmonella the bug claimed
  • 00:16:21
    another seven victims on Tuesday it all
  • 00:16:24
    began with a phone call the day Katie
  • 00:16:26
    ate her sandwich so you're saying you
  • 00:16:29
    can't come in to work yeah that's right
  • 00:16:32
    run tummy been up all night look I'm
  • 00:16:35
    short stop Sam it's going to be a busy
  • 00:16:39
    day I don't know I've been throwing up
  • 00:16:42
    as well well then you probably have the
  • 00:16:44
    worst of it listen unless you're dead
  • 00:16:47
    come in to
  • 00:16:50
    work normally of course proper hand
  • 00:16:52
    washing will stop most
  • 00:16:54
    cross-contamination but bugs like
  • 00:16:56
    salmonella and those that cause viral
  • 00:16:58
    gastro are really
  • 00:17:00
    infectious and if you're sick you
  • 00:17:03
    excrete incredible numbers of the bug so
  • 00:17:05
    however well you wash your hands you
  • 00:17:07
    can't be sure you've removed them all
  • 00:17:09
    after going to the
  • 00:17:11
    loop once more if you've been vomiting
  • 00:17:14
    some of the bugs will hang around in
  • 00:17:16
    your mouth and your nose so next time
  • 00:17:19
    you sneeze or you cough you'll probably
  • 00:17:21
    be sharing them with everyone
  • 00:17:24
    around what we've just witnessed is an
  • 00:17:27
    example of contamination like the cross
  • 00:17:30
    contamination with the raw meat we
  • 00:17:31
    looked at earlier only this time the
  • 00:17:34
    food handler is the source again the
  • 00:17:37
    best offense against these bugs is
  • 00:17:39
    separation when chopping raw meat we saw
  • 00:17:42
    that completely different boards should
  • 00:17:44
    be used in this case Sam should have
  • 00:17:47
    kept itself completely separate and not
  • 00:17:49
    come into work at all the thing is if
  • 00:17:52
    you're feeling queasy and especially if
  • 00:17:55
    you have diarrhea or you're vomiting
  • 00:17:57
    then you may be sick with something that
  • 00:17:59
    can be passed on through food like
  • 00:18:01
    salmonella or viral gastro stay at home
  • 00:18:06
    no I'm really sorry Steve I won't be
  • 00:18:08
    coming
  • 00:18:10
    in by law if you're at work and you
  • 00:18:13
    think you've got one of these illnesses
  • 00:18:15
    that can be passed on through food you
  • 00:18:17
    must tell your supervisor and of course
  • 00:18:19
    you mustn't handle any food and if you
  • 00:18:22
    think you may have contaminated any food
  • 00:18:24
    for goodness sake tell your
  • 00:18:27
    boss as food handlers we help prepare
  • 00:18:30
    the food that everyone enjoys every day
  • 00:18:33
    throughout the
  • 00:18:34
    state most consumers never think about
  • 00:18:37
    food poisoning and they shouldn't have
  • 00:18:39
    to that's our job
  • 00:19:08
    like
  • 00:19:49
    TI
  • 00:20:22
    all I'm Chris food is one of those
  • 00:20:25
    things in life that's both essential and
  • 00:20:27
    enjoyable now that go from your caught
  • 00:20:29
    on blur type cooking all the way up to
  • 00:20:31
    your local
  • 00:20:33
    Barbie in this state alone there are
  • 00:20:36
    thousands of people employed in cafes
  • 00:20:38
    fast food joints fancy restaurants and
  • 00:20:41
    other places like Hospital kitchens and
  • 00:20:43
    there's us people that help out every
  • 00:20:46
    now and then at community and charity
  • 00:20:47
    events by preparing and serving food
  • 00:20:51
    thank you very
  • 00:20:52
    much whether you're the head chef of the
  • 00:20:54
    Hilton or me we're all providing a
  • 00:20:57
    service that makes people happy it
  • 00:20:59
    should never make them sick but now and
  • 00:21:02
    then people like Joe do get sick because
  • 00:21:04
    of something bad in the food that us
  • 00:21:06
    food handlers have
  • 00:21:10
    prepared having done a fair few School
  • 00:21:13
    Fates and Community bashes I thought I
  • 00:21:15
    knew everything about how to handle food
  • 00:21:18
    safely but when I was asked to check out
  • 00:21:20
    what can go wrong to help make this film
  • 00:21:23
    I got a few
  • 00:21:25
    surprises the problem is the things that
  • 00:21:28
    cause people to get sick are invisible
  • 00:21:31
    to us don't you just love this
  • 00:21:34
    technology now these microscopic
  • 00:21:36
    organisms that we can't see are in fact
  • 00:21:39
    everywhere we've got them all through
  • 00:21:41
    our bodies and the soil's full of them
  • 00:21:44
    now most of them are harmless many are
  • 00:21:46
    even good for us helping us to digest
  • 00:21:48
    our food for example but some are very
  • 00:21:51
    bad and can cause nasty diseases like
  • 00:21:53
    tuberculosis pneumonia and food
  • 00:21:56
    poisoning which I've had it's not
  • 00:21:58
    something I want to
  • 00:22:00
    repeat you've also got to remember that
  • 00:22:02
    people can die from food
  • 00:22:05
    poisoning the tricky thing about it is
  • 00:22:08
    that you often can't tell when you're
  • 00:22:09
    eating something bad simply throwing out
  • 00:22:12
    spoiled or moldy food won't protect us
  • 00:22:15
    when people get sick it's often from
  • 00:22:18
    food that looks smells and tastes just
  • 00:22:21
    fine the sort of bugs we don't want in
  • 00:22:24
    our system can be found on raw meat
  • 00:22:26
    before it's cooked some can grow in food
  • 00:22:28
    if it's left out too long some can
  • 00:22:31
    spread by people who have
  • 00:22:33
    a gastric
  • 00:22:37
    upset although you can't see the bugs
  • 00:22:39
    because they're so incredibly
  • 00:22:41
    small they exist all right and they can
  • 00:22:45
    cause big
  • 00:22:48
    problems well they can't be seeing they
  • 00:22:51
    can be beaten it's not that hard but it
  • 00:22:55
    is a constant battle now the front line
  • 00:22:59
    in the defense against these bugs is you
  • 00:23:01
    and me the people handling the food
  • 00:23:05
    whether it be at an outdoor event in a
  • 00:23:07
    community kitchen or preparing at
  • 00:23:22
    home wherever you are the principles of
  • 00:23:25
    Defense are the same there are three
  • 00:23:27
    main areas is where those bugs will
  • 00:23:29
    taken advantage if we're not careful
  • 00:23:32
    cross-contamination temperature control
  • 00:23:34
    and personal hygiene let's take a look
  • 00:23:36
    at cross-contamination
  • 00:23:38
    first when Joe's case was investigated
  • 00:23:41
    the food poisoning was traced to the co
  • 00:23:43
    slore he'd eaten 4 days before he became
  • 00:23:45
    ill 2 hours before he ateed The
  • 00:23:48
    Volunteers in the community kitchen were
  • 00:23:50
    flat out
  • 00:23:51
    preparing merely rinsing The Cutting
  • 00:23:54
    Board will prove to be Joe's
  • 00:23:56
    downfall no matter how well the food
  • 00:23:58
    Handler washes his
  • 00:24:00
    hands or dries the
  • 00:24:12
    board and Joe was doomed the bugs had
  • 00:24:16
    already grasped their opportunity 2
  • 00:24:17
    hours
  • 00:24:19
    earlier all raw meate especially raw
  • 00:24:22
    poultry and awful Cuts has bugs on it
  • 00:24:25
    many are harmless but some are dangerous
  • 00:24:28
    the presence of a few really nasty ones
  • 00:24:31
    is revealed with a bug Cam and until
  • 00:24:33
    cooked they remain a danger now we can
  • 00:24:36
    see why simply rinsing and drying The
  • 00:24:39
    Cutting Board wasn't good
  • 00:24:41
    enough and how the bugs grabbed their
  • 00:24:44
    chance with this type of bug it doesn't
  • 00:24:47
    take many to cause
  • 00:24:51
    trouble when you play it back with that
  • 00:24:53
    bug cam it's easy enough to see what
  • 00:24:55
    went wrong but you know it's also easy
  • 00:24:58
    enough to stop the bugs from getting
  • 00:25:00
    through in the first place by keeping
  • 00:25:02
    them separate from your prepared
  • 00:25:05
    foods the simplest and best solution is
  • 00:25:08
    to have a completely separate board for
  • 00:25:10
    raw meat different colors help and of
  • 00:25:14
    course you should keep your knives
  • 00:25:15
    separate too now our food handler should
  • 00:25:18
    have waited until the right board was
  • 00:25:20
    free before he started cutting the
  • 00:25:23
    Cabbage however if you ever have to use
  • 00:25:26
    a board that's been used for raw meat
  • 00:25:29
    or you're not sure what a board's been
  • 00:25:31
    used
  • 00:25:32
    for then after washing it you'll need to
  • 00:25:35
    use either an antibacterial sanitizer or
  • 00:25:38
    a dishwasher that reaches at least 65°
  • 00:25:42
    C and remember our hands whenever they
  • 00:25:45
    come into contact with raw meat must be
  • 00:25:47
    washed thoroughly as
  • 00:25:49
    always what we've been talking about is
  • 00:25:52
    stopping
  • 00:25:53
    contamination microscopic bugs cause the
  • 00:25:55
    most serious contamination but in
  • 00:25:58
    insects and dirt from animals can also
  • 00:26:00
    get in the food so food preparation
  • 00:26:03
    areas are not for them keep everything
  • 00:26:05
    clean and your risk of contamination
  • 00:26:07
    goes right down wearing clean clothing
  • 00:26:10
    also helps it shows we have the right
  • 00:26:13
    attitude and if you have a cut or a saw
  • 00:26:16
    it should be covered to stop it getting
  • 00:26:18
    infected and maybe contaminating the
  • 00:26:20
    food wash fruit and vegetables if
  • 00:26:22
    they're visibly dirty or there's a
  • 00:26:24
    chance they've got insects or slugs on
  • 00:26:26
    them
  • 00:26:28
    packag self-service food must be
  • 00:26:31
    supervised and food on display should be
  • 00:26:33
    wrapped or covered in some way by the
  • 00:26:36
    way as far as labeling goes food made
  • 00:26:39
    for fundraising events doesn't have to
  • 00:26:41
    be labeled however if someone needs to
  • 00:26:44
    know what the ingredients are say
  • 00:26:46
    because of an allergy you must be able
  • 00:26:48
    to tell them okay back to contamination
  • 00:26:52
    the main thing to remember is to keep
  • 00:26:54
    those bugs separate from the food to be
  • 00:26:56
    eaten those bugs are looking for any
  • 00:26:58
    slip UPS during the food preparation
  • 00:27:00
    chain in the fridge raw meat should be
  • 00:27:03
    stored so that it can't contact or drip
  • 00:27:05
    on other food same applies of course
  • 00:27:07
    when you use an esy if you use some
  • 00:27:10
    leftover marinade to baste your meat
  • 00:27:12
    make sure the marinade gets a proper
  • 00:27:14
    cooking cuz it'll have the bugs from the
  • 00:27:16
    raw meat in it cooked meats must go on a
  • 00:27:19
    clean tray or plate certainly never the
  • 00:27:21
    same thing that held the r meat so
  • 00:27:24
    keeping the bugs separate from prepared
  • 00:27:26
    food so they don't contaminate ated is
  • 00:27:29
    the first step in beating the bugs the
  • 00:27:31
    second area to watch out for is
  • 00:27:33
    temperature
  • 00:27:57
    control in all 12 people suffered from
  • 00:28:00
    nausea or vomiting that
  • 00:28:02
    afternoon this case Begins the day
  • 00:28:07
    before with her fridge full up the
  • 00:28:10
    volunteer decided to leave the rice out
  • 00:28:12
    overnight figuring it would have to be
  • 00:28:14
    reheated anyway
  • 00:28:34
    that yellow stuff is bad news for humans
  • 00:28:37
    it's a toxin produced by the bacteria so
  • 00:28:40
    what went wrong bacteria don't survive
  • 00:28:43
    above
  • 00:28:44
    75° so the boiling the day before would
  • 00:28:46
    have knocked them off and it was covered
  • 00:28:48
    from then on so nothing could have got
  • 00:28:51
    in of course from the outside it looks
  • 00:28:53
    like nothing's going on but the tricky
  • 00:28:56
    little blers left spores which are like
  • 00:28:58
    eggs and they can survive boiling they
  • 00:29:01
    hatched into bacteria that found
  • 00:29:03
    themselves living in a very nice piece
  • 00:29:04
    of real estate in a very pleasant
  • 00:29:12
    climate with such nice conditions and
  • 00:29:15
    lots of time this sort of bacteria
  • 00:29:17
    starts to multiply like
  • 00:29:20
    mad by lunchtime on Sunday the rice was
  • 00:29:23
    swarming with millions of bacteria and
  • 00:29:26
    they all produced a toxin as they grew
  • 00:29:29
    while the bugs were killed during
  • 00:29:31
    reheating the toxin survived and that's
  • 00:29:34
    a poison for us if there's enough of it
  • 00:29:37
    so the moral of this story uh the little
  • 00:29:40
    blighters can be very tricky sure but we
  • 00:29:44
    also know how they operate so we can
  • 00:29:46
    stop them we know they like a nice
  • 00:29:49
    moderate temperature with enough food
  • 00:29:51
    and moisture to grow and enough time now
  • 00:29:55
    there will always be food that we want
  • 00:29:57
    to eat that bacteria like to grow in we
  • 00:30:00
    call this potentially hazardous food and
  • 00:30:03
    it includes a whole swag of things
  • 00:30:05
    including milk cream and custard cooked
  • 00:30:09
    food that has meat rice pasta eggs or
  • 00:30:12
    beans in it prepared salads and homemade
  • 00:30:15
    dressings like mayonnaise and any food
  • 00:30:17
    that contains these foods such as
  • 00:30:19
    sandwiches in other words a lot of the
  • 00:30:22
    food we handle is potentially hazardous
  • 00:30:24
    it doesn't include acidic foods like
  • 00:30:27
    jams or yog YT or dry Foods Like
  • 00:30:29
    Biscuits and cakes unless they have
  • 00:30:32
    fresh cream or Custard in them what
  • 00:30:34
    those bugs are looking for is a moist
  • 00:30:37
    place with nutrients especially protein
  • 00:30:40
    if in doubt treat it as potentially
  • 00:30:42
    hazardous and you can always check with

    your local environmental health officer
  • 00:30:46
    the way to stop bacteria growing on this
  • 00:30:48
    type of food is to watch temperature and
  • 00:30:51
    time in other words temperature control
  • 00:30:55
    the danger zone where the bugs live is
  • 00:30:57
    between 5 5 and 60°
  • 00:30:59
    C below 5° the bugs or microbes mostly
  • 00:31:04
    stop growing above 60 and they're
  • 00:31:07
    usually killed now that's fine as far as
  • 00:31:10
    it goes but what about when you can't
  • 00:31:12
    keep it under temperature control like
  • 00:31:15
    when it's on display that's where time
  • 00:31:17
    comes in the sort of bacteria we're
  • 00:31:19
    worried about here need time to multiply
  • 00:31:22
    and it takes a while for the numbers to
  • 00:31:24
    build up to where they become
  • 00:31:26
    dangerous how long
  • 00:31:28
    well 4 hours is the cut off time after 4
  • 00:31:31
    hours in the danger zone Chuck it out
  • 00:31:34
    there's a handy rule called the 2hour 4H
  • 00:31:36
    hour rule say a meat and salad roll is
  • 00:31:39
    prepared at 12:00 p.m. it can stay at
  • 00:31:42
    room temperature until 4 p.m. then it
  • 00:31:45
    must be thrown
  • 00:31:46
    out if you want to keep the roll for
  • 00:31:48
    later on then you've got to put it in
  • 00:31:50
    the fridge by 2
  • 00:31:52
    p.m. and when you take it out again say
  • 00:31:55
    at 6:30 p.m. it must be used within the
  • 00:31:58
    next 2 hours which is a total of 4 hours
  • 00:32:01
    out of temperature
  • 00:32:03
    control temperature control applies
  • 00:32:06
    right along the food preparation chain
  • 00:32:08
    once potentially hazardous food is
  • 00:32:10
    thored it should be used as soon as
  • 00:32:12
    possible or stored in the fridge or
  • 00:32:14
    cooler to keep it out of the danger zone
  • 00:32:18
    when transporting potentially hazardous
  • 00:32:20
    food use an insulated cooler with plenty
  • 00:32:22
    of ice or cool
  • 00:32:25
    packs however if it is transported in
  • 00:32:27
    the danger zone then of course that time
  • 00:32:30
    then counts as part of the 4 hours
  • 00:32:33
    temperature and time the bugs can use
  • 00:32:35
    them if we get slack give them the ideal
  • 00:32:38
    conditions and they'll take advantage
  • 00:32:40
    every time but as we've been seeing we
  • 00:32:43
    can also use temperature and time to
  • 00:32:45
    beat the bugs we know about the
  • 00:32:47
    temperature danger zone and we have the
  • 00:32:49
    2hour 4H hour rule temperature control
  • 00:32:53
    also applies to cooking and cooling
  • 00:32:56
    food now it sounds obvious but food must
  • 00:33:00
    be cooked thoroughly and this especially
  • 00:33:02
    applies to rolled roasts patties and
  • 00:33:06
    sausages bacteria which naturally occur
  • 00:33:09
    on the surface can end up in the middle
  • 00:33:11
    of these types of meats so no pink in
  • 00:33:14
    the middle for these ones chicken must
  • 00:33:16
    be cooked till the juices run clear and
  • 00:33:19
    always stir food in a microwave to make
  • 00:33:22
    sure it's heated evenly if food has to
  • 00:33:24
    be cooled after cooking do it as quickly
  • 00:33:27
    as possible aim to get it down to 21° in
  • 00:33:30
    2 hours and then down to 5° after a
  • 00:33:32
    further 4 hours you can put large
  • 00:33:35
    amounts of cooked food in Shallow
  • 00:33:37
    containers to speed up the cooling
  • 00:33:39
    that's about it on the temperature
  • 00:33:41
    control
  • 00:33:42
    front the third and final area where the
  • 00:33:45
    little blers look for opportunities is
  • 00:33:47
    personal hygiene and
  • 00:33:49
    cleanliness our hands are always picking
  • 00:33:51
    up microbes so they can easily transfer
  • 00:33:53
    them to food
  • 00:33:57
    thorough hand washing is one of the most
  • 00:33:59
    important ways to help prevent the
  • 00:34:01
    transfer of
  • 00:34:02
    microbes soap helps to get off the
  • 00:34:04
    grease and fat drying off is important
  • 00:34:08
    there can be bugs in the moisture left
  • 00:34:09
    on your hands so a proper hand wash is
  • 00:34:13
    always the goat before you start
  • 00:34:14
    handling food as we saw earlier you must
  • 00:34:18
    also wash your hands after handling raw
  • 00:34:20
    meats and after using the toilet and
  • 00:34:23
    don't use your apron or tea towel at
  • 00:34:25
    these times to dry off you could be
  • 00:34:27
    transfer referring the little blighters
  • 00:34:28
    and they'll be there next time you wipe
  • 00:34:30
    your
  • 00:34:31
    hands by the way if you use disposable
  • 00:34:34
    gloves you've got to change them just as
  • 00:34:37
    often as you'd wash your hands at
  • 00:34:39
    community events Plumbing can be in
  • 00:34:41
    short supply but you've got to keep up
  • 00:34:43
    your standards you really need warm
  • 00:34:45
    running water for good hand washing a
  • 00:34:48
    container with a tap will do the trick
  • 00:34:50
    and you can top it up with hot water if
  • 00:34:52
    you need to warm it up I guess that is
  • 00:34:54
    an awful lot about handwashing but it
  • 00:34:57
    really is important and you end up doing
  • 00:34:59
    quite a lot of it especially before
  • 00:35:01
    handling food or after touching raw meat
  • 00:35:04
    or using the toilet that'll really help
  • 00:35:06
    in the fight against the bugs but there
  • 00:35:09
    is one time when even washing your hands
  • 00:35:11
    perfectly isn't good enough
  • 00:35:40
    I'm going to be it was found that the
  • 00:35:43
    bacteria causing young Katie such
  • 00:35:45
    distress was salmonella the bug claimed
  • 00:35:47
    another seven victims that day it all
  • 00:35:50
    began with a phone call the day Katie
  • 00:35:53
    ate a sandwich you don't think you make
  • 00:35:55
    it that's right runny tummy been up all
  • 00:35:59
    night I don't have enough volunteers as
  • 00:36:01
    it is Sam it's going to be so busy oh I
  • 00:36:04
    don't
  • 00:36:05
    know I mean I've been throwing up as
  • 00:36:07
    well you probably have the worst of it
  • 00:36:09
    listen unless you're at death door
  • 00:36:11
    you've just got to come and
  • 00:36:13
    help normally of course proper
  • 00:36:16
    handwashing will stop most
  • 00:36:18
    cross-contamination but bugs like
  • 00:36:19
    salmonella and those that cause viral
  • 00:36:22
    gastro are really infectious and if
  • 00:36:25
    you're sick you excrete incredible
  • 00:36:27
    number numbers of the bug so however
  • 00:36:29
    well you wash your hands you can't be
  • 00:36:31
    sure you've removed them all after going
  • 00:36:33
    to the L what's more if you've been
  • 00:36:35
    vomiting some of the bugs will hang
  • 00:36:37
    around in your mouth and nose so the
  • 00:36:39
    next time you cough or sneeze you'll
  • 00:36:42
    probably be sharing them with everyone
  • 00:36:46
    around the case we've just been looking
  • 00:36:49
    at is an example of contamination much
  • 00:36:52
    like the cross contamination we saw with
  • 00:36:53
    the raw meat earlier only this time the
  • 00:36:57
    sauce is is the food handler again the
  • 00:37:00
    best defense against the bugs is
  • 00:37:02
    separation when chopping up raw meat we
  • 00:37:05
    saw that completely different board
  • 00:37:06
    should be used now in this case Sam
  • 00:37:10
    should have stayed completely separate
  • 00:37:12
    and never come in to work at all the
  • 00:37:15
    thing is if you're feeling queasy and
  • 00:37:17
    especially if you have diarrhea or
  • 00:37:19
    you're vomiting then you may be sick
  • 00:37:22
    with something that can be passed on
  • 00:37:23
    through food like salmonella or viral
  • 00:37:26
    gastro
  • 00:37:28
    stay at home no I'm really sorry Steve
  • 00:37:32
    but I just can't make
  • 00:37:33
    it by law if you're preparing food and
  • 00:37:37
    you think you've got one of these
  • 00:37:38
    illnesses that can be passed on through
  • 00:37:39
    food you must tell your supervisor and
  • 00:37:43
    of course you mustn't handle any food if
  • 00:37:45
    you think you may have contaminated some
  • 00:37:47
    food for goodness sake tell whoever's in
  • 00:37:50
    charge well that's about it I better get
  • 00:37:55
    back to the barbecue and do my bit
  • 00:38:00
    as food handlers we help prepare the
  • 00:38:02
    food a lot of people enjoy at community
  • 00:38:04
    and social events throughout the year
  • 00:38:07
    now most of those happy eaters never
  • 00:38:09
    think about food poisoning and they
  • 00:38:11
    shouldn't have to that's our job
