Produced by Clostridum botulinum. This bacteria is a food contaminate, growing & producing its toxin into the food. Humans ingest the "poisoned food" & the toxin is absorbed through the digestive tract. Muscles cannot contract causing flaccid paraylsis. One pint of this toxin could wipe off entire earth!
Botulinum toxin-this toxin blocks the relase of the acetylcholine which tells muscle to contract. Death is from heart or respiratory failure.
