Food-borne illness is any illness resulting from the spoilage of contaminated food. Also referred to as food-borne disease and informally as food poisoning. In short, contamination can be as the result of pathogenic bacteria, viruses, or parasites. Contamination can also be as a result of toxins, such as poisonous mushrooms and various species of beans. In particular, the potential for contamination apply to both real food and feed, and is not unique to raw food diets for cats and dogs. Common food-borne illness symptoms include vomiting, diarrhea, abdominal pain, fever and chills. (see: Wikipedia).
