Toxins from seafood mushrooms and molds present the greatest potential for?

From my knowledge, Most food poisoning is primarily caused by bacteria, viruses, and parasites rather than just toxic substances in 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). There have been some cases where mushrooms in the grocery have been mistaken for safe ones to eat when really they were toxic, and puffer fish not being prepared correctly therefor the food being contaminated and dangerous to eat. Foods that are moldy may also have invisible bacteria growing along with the mold. Yes, some molds cause allergic reactions and respiratory problems. And a few molds, in the right conditions, can produce "mycotoxins," poisonous substances that can make you very sick. While some molds are common in foods (such as blue cheese), other molds can produce toxins that cause illness depend on whether or not on how the food is prepared and how long it's been out to effect this.
