Let's talk about Toxins
Toxins aresubstances created by plants and animals that are poisonous (toxic) to humans. Toxins may also include some medicines that are helpful in small doses, but poisonous in large amounts. Most toxins that cause problems in humans come from germs such as bacteria.
Natural toxins in food
Natural toxins are toxic compounds that are naturally produced by living organisms. These toxins are not harmful to the organisms themselves but they may be toxic to other creatures, including humans, when eaten. These chemical compounds have diverse structures and differ in biological function and toxicity.
Biological toxin
A toxic substance originating from a living organism. Most biological toxins are used for defense; are very large, complex molecules; and are among the most toxic substances known to higher animals. Botulinum toxin is the most deadly substance known to humans.
