Food-borne bacterial toxins

Abstract

Food poisoning caused by the ingestion of preformed bacterial toxins is considered in relation to comparative symptoms, procedures for extraction and purification of the causal toxins, their chemistry, serology, assay procedures and pharmacology, in so far as these are known.The bacteria discussed in this context are Clostridium botulinum, C. perfringens, Staphylococcus aureus, Bacillus cereus, and Vibrio parahemolyticus. The possible roles of the enterococci, Proteus, E. coli and of unknown species, in relation to production of non-antigenic toxic substances, are discussed briefly.Requirements for prevention of the various forms of bacterial food poisoning are outlined.
