Molds, Toxins, & Contaminants
Most food poisoning is caused by bacteria, viruses, and parasites rather than toxic substances in the food. But, some cases of food poisoning can be linked to either natural toxins (such as those in some mushrooms and pufferfish) or chemical toxins (such as pesticides or melamine). While some molds are desirable in foods (such as blue cheese), other molds can produce toxins that cause illness.
