Botulinum toxin is the most toxic substance known to man. Even a small amount is deadly. A certain bacteria makes the toxin. It has the potential to be used as a weapon. When used as a weapon, the toxin can be released into the air or placed in the food supply.
The toxin can be used to treat other health conditions.
Botulinum toxin poses a great threat. It’s easy to make and move around. Only 1 gram that’s evenly released and breathed in could kill 1 million people.
US troops get a botulinum toxoid vaccine. This protects them from disease. This makes it harder to use as a weapon against a military enemy.
Botulinum toxin doesn’t have any color or odor. The toxin can’t be passed between people.
