a. The bacteria that causes botulism are found in soil‚ water‚ animal guts and dung. When the spores exposed to low oxygen and certain temperature‚ they produce botulinum toxin‚ able to germinate‚ metabolize‚ food sources through an aerobic respiration to produce toxin. The toxin blocks the release of acetylcholine from motor nerve endings causing paralysis symptoms. The botulism either food born‚ eating contaminated home-canned foods where the fermentation takes place. or through abrasion in the
