What are foodborne toxins? Foodborne toxins are toxins that are found in different foods that can cause illness when they are consumed. Some are naturally occurring toxins that are found in certain foods, and others are produced by bacteria that have contaminated a food item.
Food poisoning. In botulism food poisoning, the toxin is produced by the vegetative cells of C botulinum in contaminated food, and preformed toxin then is ingested with the contaminated food. The incubation time can vary from a few hours to 10 days, but most commonly is 18â36 hours.linical Manifestations.
