Enterotoxin analyses

Food-poisoning bacteria may produce poisonous compounds or toxins either in food or in the human intestines. The Food and Feed Microbiology Research Unit of Evira analyses bacterial isolates and food samples sent by laboratories for enterotoxins.

Bacillus cereus

  • Detection of diarrhoeal-type enterotoxin in bacterial cultures by reversed passive latex agglutination
  • Detection of emetic toxin (cereulide) with a sperm bioassay in bacterial cultures, and determination by chemical analysis in food samples in collaboration with the Chemistry and Toxicology Research Unit

Clostridium perfringens

  • Detection of toxin gene (cpe) by PCR in bacterial cultures

Coagulase-positive staphylococci

  • Detection of staphylococcal enterotoxins (A, B, C, D and E) in bacterial cultures and food samples, using the VIDAS method
