Food poisoning, how does food become contaminated

food can become contaminated through poor handling and storage and through lack of personal hygiene by the people who prepare had serve it. Harmful bacteria can also be found in the soil, on animals and on people, so it is possible for foods such as raw meat, poultry and vegetables to contain these bacteria from the start.

Food can also become contaminated through cross-contamination; this can happen in two ways -

1. During food preparation: if hands, equipment or chopping boards have been contaminated with bacteria from raw food; and this is then passed on to food that is not going to be cooked again.

2. During storage: if food comes into contact with contaminated items in the refrigerator. Food should always be covered, and uncooked food stored below cooked and salads. See 'Food Poisoning'
