If we neglect safe practices we may have an outbreak of food poisoning. If we eat food which contains harmful micro-organisms, chemicals or toxins (poisons), that food can make us sick. To describe our illness we can use the terms food-borne illness, food-borne disease, or food poisoning. Food poisoning is caused by four agents: bacteria, viruses, parasites and chemicals.
Food poisoning occurs when you swallow food or water that contains bacteria, parasites, viruses, or the toxins made by these germs. Most cases are caused by common bacteria such as Staphylococcus or E. coli. Food poisoning can affect one person or a group of people who all ate the same food. It is more common after eating at picnics, school cafeterias, large social functions, or restaurants. When germs get into the food, it is called contamination. This can happen in different ways: 1  Meat or poultry can come into contact with bacteria from the intestines of an animal that is being processed.  Water that is used during growing or shipping can contain animal or human waste.
