Abstract:

The Staphylococcus aureus colloidal gold marked specific monoclonal antibody test plates co-developed by Tianjin University of Commerce and Lanzhou Institute of Biological Products were used in the investigation of positive rate of Staphylococcus aureus in 240 samples of raw milk collected from individual raising households in central south and northeast China. Staphylococcus aureus was not detected in the raw milk samples collected from central south China including Huan, Hubei and Henan provinces, but the microbial pollution status in raw milk was not optimistic because the positive rates of Staphylococcus aureus were 10%, 30% and 100% respectively in the samples collected from Liaoning, Jilin and Heilongjiang provinces. The investigation prove that the Staphylococcus aureus colloidal gold marked specific monoclonal antibody test plates are fast, convenient and accurate examination products. Therefore, it is worth popularizing in raw milk market.

Key words: raw milk, Staphylococcus aureus, colloidal gold marked specific monoclonal antibody test plate
