目的掌握福建省食品中沙门菌的污染状况及血清型的分布特征,为评价和预警食品安全状况及风险评估提供可靠的基础数据。方法设立省内9个设区市监测点,随机采集市售食品,按GB 4789.4《沙门菌检验》检测。结果2000—2013年,共采集11类9 712份食品,沙门菌总检出率3.1%,其中生畜禽肉沙门菌检出率12.6%、水产品2.6%、蛋品2.4%。检出的303株沙门菌分属7个群40个血清型,前5位为德尔卑沙门菌24.8%、鼠伤寒沙门菌10.9%、阿贡纳沙门菌10.6%、肠炎沙门菌9.6%和韦太夫雷登沙门菌5.3%。结论福建省生畜禽肉、水产品、蛋品和熟肉制品等存在不同程度的沙门菌污染,部分血清型别优势明显,应降低生畜禽肉中沙门菌的污染率,以减少食源性疾病。
Objective To understand the status of contamination and serotype distribution of Salmonella in food in Fujian Province and provide reliable basic data for evaluating and early warning of food safety status and risk assessment. Methods The establishment of nine monitoring points in the province set up a city, random collection of commercially available foods, according to GB 4789.4 “Salmonella test” test. Results From 2000 to 2013, a total of 9 712 foodstuffs were collected in 11 categories. The total detection rate of Salmonella was 3.1%. The detection rate of Salmonella in livestock and poultry was 12.6%, 2.6% for aquatic products and 2.4% for eggs. The 303 strains of Salmonella isolated belong to 7 serogroups and 40 serotypes. The top five were 24.8% of Salmonella delphi, 10.9% of Salmonella typhimurium, 10.6% of Salmonella gonorrhoeae, 9.6% of Salmonella enteritidis and 9.6% of Salmonella enteritidis Salmonella typhi 5.3%. Conclusions There are varying degrees of Salmonella contamination in raw meat, aquatic products, egg products and cooked meat products in Fujian Province. Some of the serotypes have obvious advantages and should reduce the contamination rate of Salmonella in live animals and poultry to reduce the food intake disease.
