Clos·trid·i·um bot·u·li·'num

a bacterial species that occurs widely in nature and is a frequent cause of food poisoning (botulism) from preserved meats, fruits, or vegetables that have not been properly sterilized before canning. The main types, A-F, are characterized by antigenically distinct, but pharmacologically similar, very potent neurotoxins, each of which can be neutralized only by the specific antitoxin; group C toxin contains at least two components; the recorded cases of human botulism have been due mainly to types A, B, E, and F; infant botulism occurs when colonization of the gastrointestinal tract with Clostridium botulinum results in absorption of the toxin through the gastrointestinal wall; type Cα causes botulism in domestic and wild water fowl; Cβ and D are associated with intoxications in cattle. Type E is usually associated with improperly processed fish products.

Mariam Al-Hajiri, stated that the milk powder (Similac Gain Plus) for three-year olds imported for the Kingdom of Bahrain's local markets from Irish and not New Zealand origins, and after laboratory testing of specimens was found to be free from the toxic clostridium botulinum bacteria, and she assured citizens and residents that according to the World Health Organization (WHO)'s that bacteria-contaminated milk had been exported to the following countries: Australia, Colombia, China, Malaysia, New Zealand, KSA, Singapore, Thailand and Vietnam.

Botulism is a serious, paralytic illness caused by the action of neurotoxins, usually produced by Clostridium botulinum. These toxins block the release of the neurotransmitter acetylcholine at the neuromuscular junction, preventing muscle contraction and resulting in a characteristic floppy paralysis.
