Staphylococcal enterotoxin is a toxin that is produced by the bacteria Staphylococcus aureus. It is a toxin found inside the gastrointestinal tracts of the human body which is why it is called an enterotoxin and it results in food poisoning when consumed by humans.
Staphylococcal enterotoxin is proteinous in nature and it can be found on dairy products such as milk or cheeses that have been contaminated by Staphylococcus aureus.
After consumption of the contaminated milk or cheeses, the person begins to experience symptoms of nausea, diarrhea as well as vomiting.

The best way to avoid food poisoning by Staphylococcal enterotoxin is to avoid eating contaminated foods.
