Description
Summary:Objective To study on the contamination status of foodborne pathogens in frozen minced meat products on the market. Methods China national standard method was applied to detect Listeria monocytogenes, Staphylococcus aureus and Salmonella spp. Totally 3 905 frozen minced meat product samples were randomly collected. Results 536 positive samples were detected in 3 905 frozen minced meat products samples. The overall detection rate of the three pathogens was 13.73%. The detection rate of Listeria monocytogenes, Staphylococcus aureus and Salmonella spp. was 5.71% (223/3 905), 8.32% (325/3 905) and 0.72% (28/3 905), respectively. The detection rate of Salmonella spp. in frozen minced pork was the highest among different kinds of samples. The detection rate of Salmonella spp. in frozen meat products in unpackaged samples was higher than that in packaged samples. The main reasons for the pollution include: firstly, food raw materials were polluted; secondly, there were many processing steps, and their quality control was not strictly performed; thirdly, it was difficult to guarantee the cold chain of frozen minced meat products in transportation. Conclusion There was pathogenic contamination in frozen minced meat products on the market. The hygienic situation need to be improved.
