Abstract
Staphylococcal food poisoning is strictly an intoxication which is caused by a water-soluble protein called enterotoxin that is secreted by staphylococcal cells, i.e. an exotoxin. After a general discussion of the properties of the enterotoxins, methods and media employed for producing high toxin yields are detailed. Mechanisms whereby these toxins are secreted differ in that enterotoxin A behaves as a primary metabolite and enterotoxin B acts as a secondary metabolite. Several studies on and explanations of the synthesis of enterotoxins are presented. Assay methods for these toxins that are discussed include bioassay techniques and serological procedures. Finally, some general aspects of the epidemiology of staphylococcal intoxications are described.
