What are food borne disease outbreaks and why do they occur?

Food borne disease: Food can spoil (the warmed potato salad at a picnic is classic), can become bacterially toxic (due to inadequate canning practices) or carry bacteria from the fingers of food preparers in restaurants, or improperly cleaned fresh vegetables picked by infected field workers. Use caution although we have to rely upon government diligence to prevent some of these causes.

Contaminated food: Food born illnesses come from bacterial toxins or bacteria or viruses that may contaminate food that is eaten. Many animals are natural carriers of these bacteria and do not have symptoms of illness, but foods then that are inadequately washed or cooked may have fecal residue from fertilizers and are spread by improper hand washing and food preparation.
