Abstract: Objective The study was made to investigate and analyze the status of the contamination of staphylococcus aureus and enterotoxin in bioproducts of shrimp．Methods Staphylococcus aureus was tested according to GB/T4789.10-2003 and its enterotoxin was determined by mini-VIDAS Automatic Luciferaseimmunization Analyzer．Results It is found out that detection rate of staphylococcus aureus is 68.2％for quick freezing shrimps，with detection rate of 40.0％for enterotoxin Staphylococcus aureus thereof．Detection rate of staphylococcus aureus is 31.8％for dehydration shrimps，with demcfion rate of 100.0％for enterotoxin Staphylococcus aureus thereof．Conelusion It revealed that contamination of staphylococcus aureus and enterotoxin in the shrimp byproducts is serious and enterotoxin detection of Staphylococcus aureus in the shrimps byproducts should be strengthen．
