Innovative Application of Mass Spectrometry for the Characterization of Staphylococcal Enterotoxins Involved in Food Poisoning Outbreaks

ABSTRACT Staphylococcal poisoning is a common food-borne disease for which immunoassays to detect enterotoxins were developed, but these assays often lead to false diagnoses due to interferences or lack of specificity. Absolute quantitative mass spectrometry was for the first time successfully applied to an investigation of a staphylococcal outbreak due to coconut pearls.
