Contrary to common belief, it is a myth that unprocessed and organic foods are free of harmful chemicals. At various levels, all substances are toxic at some point and potentially harmful. Naturally occurring toxins still occur in organic foods as safely grown without pesticides or herbicides. Some would only be hazardous when a food is eaten in excessive amounts, but others can pose serious danger.
This list of toxicants can be naturally occurring in our foods from its normal composition or from natural bacterial/mold growth. These chemicals are unlike others that can be caused by environmental factors, such as extreme weather increasing toxins in your food.

More toxic than cyanide and without a known antidote, it targets the central nervous system and can cause death from respiratory paralysis. Don’t try eating Pufferfish unless you know it’s been prepared by a licensed fish cutter.
