Staphylococcal Enterotoxins: Description and Importance in Food.

Abstract in brief

• Staphylococcal enterotoxins (SEs) are highly virulent proteins produced by Staphylococcus bacteria that can cause food poisoning and other health issues like skin infections and pneumonia, and are resistant to heat, pH changes, and enzymes.
• Over 24 SE genes are known, with recent discoveries increasing this to 33, including new variants, and these genes are often found on mobile genetic elements like plasmids and prophages, enabling the bacteria to produce diverse toxins.
• The importance of detecting SEs lies in their role in food safety and public health, leading to the development of methods like liquid chromatography and mass spectrometry to quickly identify these toxins in contaminated food and samples.
