Contamination is and yellow and white boxes how it is caused and how to prevent it
    • Cross Contamination Bacteria Illness PreventionLearning Objectives• To understand what Cross contamination is• To Understand how Cross Contamination happens• To Understand what are high risk foods• To Understand how to help prevent Cross ContaminationExplain what Cross Explain what cross If you could explain thecontamination is?

    • High Risk,Cross Contamination Low risk Cross contamination Bacteria Illness Prevention Cross Contamination what is it? The definition of cross contamination isDefinition: Cross contamination is what happens when bacteria from onefood item are transferred to another food item, often by way of unwashedcutting boards or countertops, as well as knives and other kitchen tools, oreven unwashed hands. Cross contamination can in turn lead to foodpoisoning.You have already looked at Cross Contamination and its causes, can youthink of anything we do in our own kitchens at home or at school that couldlead to Cross Contamination if we did not follow the correct food Hygieneand safety procedures?Explain what Cross Explain what cross If you could explain thecontamination is?

    • Cross Contamination Bacteria Illness Prevention Pay close attention to the words in RED during this lesson. One of the most common ways to spread bacteria is cross-contamination. Cross Contamination (definition): cross-contamination is when bacteria spreads from one food to another. how does that happen? There are lots of different ways. First thing you need to remember is that there are lots of potentially hazardous foods – stuff like raw meat and fish and chicken. They need to get cooked to kill the bacteria that’s in them. When these foods are raw you need to make sure they don’t touch foods that don’t have to be cooked – like lettuce, tomatoes, dairy products etc.Explain what Cross Explain what cross If you could explain thecontamination is?

    • Cross Contamination Bacteria Illness PreventionUsing Colour-Coded Cutting BoardsThe colours help you keep track of which cutting boards are reserved for which types offoods, so that youre less likely to cut lettuce on the same board you just used forprepping RAW POULTRYHere are the different cutting board colours and their meanings Green: Fruit and salads Yellow: Cooked meats Blue: Fish White: Dairy products Brown: Vegetables Red: Raw meatsExplain what Cross Explain what cross If you could explain thecontamination is?

    • Cross Contamination Bacteria Illness Prevention How can Cross Contamination take place?Cross-contamination in food preparation is a serious concern, particularly inrestaurants and other commercial kitchens. Many foods (uncookedmeats, poultry, fish, etc) may be contaminated bymicroorganisms, bacteria, etc. Cross-contamination is when these bacteriatransfer from that food item to another object (your hands, cuttingboard, knife, etc). It can also refer to when contaminants on an object orperson are transferred to food items (someone who is ill doesnt wash theirhands before preparing food). Cross-contamination can result in food illnesseswhich can be quite serious.Explain what Cross Explain what cross If you could explain thecontamination is? Contamination is and yellow and white boxes how it is caused and how to prevent it
    • Cross Contamination Bacteria Illness Prevention To prevent cross-contamination, follow these steps:•Wash hands thoroughly with hot water and soap before handling food items. Ifhandling raw or undercooked meat, poultry, fish, eggs, etc., also wash hands afterhandling such items.•Use separate or disposable wipes/sponges for cleaning surfaces in betweenpreparation stages. Contaminants can live in sponges and dishcloths. Thoroughly washany prep items (cutting boards, knives, mixing bowls) in between prep stages•Keep raw and cooked items separate to avoid contaminating the cooked items(cooking kills most common contaminants). Keep raw meats, poultry, fish, etc, on thebottom shelf of your fridge to prevent leaks from contaminating other itemsExplain what Cross Explain what cross If you could explain thecontamination is?

    • Cross Contamination Bacteria Illness PreventionThe refrigerator is a machine thatkeeps our food cold, at atemperature where bacteria growsat a minimal rate, and thereforepreserves our food for much longer.Before the refrigerator wasinvented people used to keep foodcold in cellars or in undergroundcaves lined with snow or ice (if theywere around). Otherwise, food waspreserved using other methodssuch as smoking, salting, pickling ordrying. Most of these methods offood preservation have beenaround since the time of the RomanEmpire or before.

    • Cross Contamination Bacteria Illness Prevention REMEMBERAlways wash hands after any action that could contaminate hands, such as visiting thetoilet, after handling waste food and after handling raw food as they are all sources ofbacteria which can be transferred to food.Do not use the same equipment or surfaces for cutting or preparing raw food thencooked food. If this is impossible, make sure that equipment and surfaces used forraw food are thoroughly cleaned and sterilised before cooked food is used on them.Use a colour coding system for equipment such as chopping boards and knives.Keep the food premises clean and maintain high standards of cleanliness and personalhygieneExplain what Cross Explain what cross If you could explain thecontamination is?
