Food Poisoning What is food poisoning? • An illness you get by eating contaminated food. • Can be bacterial • Can be chemical (pesticides, cleaning chemicals) • Can be from metals (copper) High Risk Foods Bacteria like foods that are moist and high in protein. These include: • Meat Fish • Poultry Dairy products • Eggs Gravies • Stocks Sauces • Shellfish Seafood What do bacteria need to multiply? • • • • Food Moisture Warmth Time What can you tell me about each of these? Critical Temperatures High risk and perishable foods should be kept out of the danger zone of between 5ºC and 63ºC. The core temperature of cooked food needs to be at least 75ºC. Chilled food should be stored below 5ºC. Name the six types of food poisoning bacteria. • • • • • • Campylobacter Salmonella E. coli Clostridium perfringens Listeria monocytogenes Staphylococcus aureus In groups choose one of the food poisoning bacteria. Spend five minutes revising your bacterium. Spend five minutes teaching another group about the bacterium. Tell them where it is found, what symptoms it causes and how long the symptoms take to develop. After five minutes quiz the group to see how much they know. Swap over and allow the other group to teach you about their bacterium. Who scored the highest? Who am I? Produces a toxin which may survive cooking. Large numbers needed to cause illness. Symptoms are severe vomiting, abdominal pain, diarrhoea. Found on skin, in cuts and boils and up the nose. Staphylococcus aureus Who am I? Found in animal faeces. Found in soil, manure, sewage, raw meat and poultry. Produces spores which may not be killed during cooking. Symptoms abdominal pain, diarrhoea, nausea. Clostridium perfringens Who am I? • Found in raw poultry and meat. • Illness caused by small numbers of bacteria. • Symptoms include fever, headache, abdominal pain and bloody diarrhoea. Campylobacter
