How are food-borne illnesses contracted?

Answer 1

A person can get sick from contaminated food because of microbes or toxins. When contaminated food is eaten, toxins or microbes are released into the gastrointestinal tract, causing vomiting and diarrhea.

Answer 2

Food-born illnesses are contracted from food, most often by eating, but rarely by food handlers and preparers. An example would be trichinosis -- the infection of a parasite acquired by eating certain insufficiently cooked meats.
