2011—2016年广西壮族自治区市售肉及肉制品食源性致病菌污染状况分析

目的 了解广西壮族自治区市售肉及肉制品中食源性致病菌污染状况,为有效开展食源性疾病防控提供科学依据。方法 2011—2016年从广西壮族自治区14个市采集5类市售肉及肉制品共10 927份,按照国家标准方法进行9种食源性致病菌检验。结果 10 927份样品的食源性致病菌总检出率为5.0%(548/10 927),食源性致病菌检出率按样品种类依次为调理肉制品(33.3%,33/99)、生畜肉(24.5%,73/298)、生禽肉(24.2%,67/277)、冷冻肉糜制品(14.4%,14/97)、熟肉制品(3.6%,361/10 156)。检出的主要致病菌为沙门菌、金黄色葡萄球菌和单核细胞增生李斯特菌。生禽肉中未检出弯曲菌和致泻大肠埃希菌,调理肉制品中未检出致泻大肠埃希菌,熟肉制品中未检出志贺菌。熟肉制品各年度检出率范围为0.9%～4.9%。结论 广西壮族自治区市售肉及肉制品受到不同程度食源性致病菌污染,且污染持续多年存在。

Analysis on the contamination of foodborne pathogens in meat and meat products sold in the market of Guangxi in 2011-2016

Objective To investigate the contamination of foodborne pathogens in meat and meat products of Guangxi, and provide reference to the effective prevention and control of foodborne disease. Methods Five kinds of meat and meat products sold in the market were collected between 2011 and 2016 from 14 cities of Guangxi. The samples were detected for 9 kinds of foodborne pathogens according to the national standard method. Results A total of 10 927 samples were detected. The total positive rate of foodborne pathogens was 5.0%(548/10 927). The positive rates of the meat and meat products were processed meat products (33.3%, 33/99),raw livestock meat (24.5%, 73/298), raw poultry meat (24.2%, 67/277), frozen minced meat products (14.4%, 14/97) and cooked meat products (3.6%, 361/10 156). The main pathogens were Salmonlla, Staphylococcus aureus and Listeria monocytogenes. None of the Campylobacter and diarrhea Escherichia coli were found in raw poultry meat. No detection of diarrhea Escherichia coli in the processed meat products. No detection of Shigella in cooked meat products. The annual detection rate of cooked meat products was 0.9%-4.9%. Conclusion The contamination of pathogens existed in meat and meat products of Guangxi in varying degrees. And the contamination persisted for many years.
