What Is the Most Toxic Substance Known to Man?

Answer

Botulinum toxin is the most toxic substance known to man. A sheer 90 to 270 nanograms of botulinum toxin could be sufficient to kill an average 90 kilogram adult, depending on the method of introduction into the body. Four kilograms of the toxin, if equally distributed, would be more than enough to wipe out the entire human race.
