Cyanide Poisoning — Publications

Plant cells can be ruptured by cutting, wilting, freezing, drought, crushing, trampling, chewing or chopping. Once plants containing cyanide have been consumed, the toxin rapidly enters the blood stream and is transported throughout the body of the animal. Cyanide inhibits oxygen utilization by the cells in the animal’s body.
