What causes food poisoning?

Answer 1

According to WebMD (link attached), there are over 250 diseases that cause food poisoning. These include pathogenic bacteria, viruses and parasites. Salmonella is one of many causes of foodborne illness (aka food poisoning) and is a bacterial infection that can be passed on to humans from domestic and wild animals, including poultry, pigs, cattle, and pets. But most often, it is caused by drinking unpasteurized milk or by eating undercooked poultry and poultry products such as eggs. Any food prepared on surfaces contaminated by raw chicken or turkey can also become tainted with salmonella. Less often, the illness may stem from food contaminated by a food worker. Salmonella can escape from the intestine and go into the blood and travel to other organs. It may become a chronic infection in some people, who can be symptom-free yet capable of spreading the disease to others. You also have Campylobacter, E. coli, Clostridium, Staphylococcus, Cyclospora, Giardia and many others.
