摘要
为了解广西部分地区生鲜畜禽肉中食源性致病菌污染状况,对广西南宁、贵港、梧州、贺州4个市2015年-2016年具有代表性的超市和市场销售的生鲜畜禽肉随机采集2 326份,按照我国食品国家安全标准GB 4789系列标准进行沙门菌、金黄色葡萄球菌、单增李斯特菌、霍乱弧菌、副溶血性弧菌、大肠埃希菌O157:H7的检测。结果显示,2 326份样品中共检出致病菌1 178株,检出率为50.64%。其中沙门菌、金黄色葡萄球菌、副溶血性弧菌、霍乱弧菌、单增李斯特菌的检出率分别为27.94%(650/2 326)、16.51%(384/2 326)、2.75%(64/2 326)、1.98%(46/2 326)、1.46%(34/2 326),未检出大肠埃希菌O157∶H7。猪肉、牛肉、鸡肉、鸭肉样品中致病菌检出率分别为43.80%(654/1 493)、46.90%(106/226)、77.13%(290/376)、55.41%(128/231),四者差异显著(P<0.05)。超市和市场样品中致病菌检出率分别为58.26%(388/666)、47.59%(790/1 660),两者差异显著(P<0.05)。4个市样品中致病菌检出率分别为南宁市70.56%(326/462)、贵港市56.47%(314/556)、贺州市43.62%(325/745)、梧州市37.83%(213/563),四者差异显著(P<0.05)。结果表明,所监测的4个地区生鲜畜禽肉受致病菌污染严重,以沙门菌和金黄色葡萄球菌为主,相关部门应加大对畜禽肉类监管力度,确保消费者的食肉安全。
To investigate and indentify the contamination of food-borne pathogens in raw livestock and poultry meats in part of GuangXi from 2015 to 2016, 2 326 samples were collected from supermarkets and markets in 4 cities of Guangxi（Nanning,Guigang, Wuzhou and Hezhou）, and supposed to analyze 6 kinds of food-borne pathogens, including Salmonella, Staphylococcus aureus , Listeria monocytogenes , Vibrio cholerae,Vibrio parahaemolyticus,Escherichia coli O157：H7 according to our national food safety stands of GB 4789.The result showed that totally 1 178 strains of food-borne pathogens were detected in the 2 326 samples,with the detection rate of 50.64%.The detection rates of Salmonella, Staphylococcus arureus, Vibrio parahaemolyticus ,Vibrio cholerae ,Listeria monocytogenes were 27.94 % （650/2 326）, 16.51% （384/ 2 326）,2.75%（64/2 326）,1.98%（46/2 326）and 1.46%（34/2 326） respectively,Escherichia coli O157.H7 were not detected.The detection rates of pork, beef, chickens, ducks were 43.80 % （654/1493）, 46.90 % （106/ 226）, 77.13 % （290/376） and 55.41% （ 128/231） respectively. There were statistically significant differences in the 4 rates（P〈0.05）.The detection rates of supermarkets and the markets were 58.26% （388/666）and 47.59%（790/1 660）.There were statistically significant differences in the 2 rates（P〈0.05）.The detection rates in Nanning,Guigang, Hezhou,Wuzhou were 70.56%（326/462）,56.47%（314/556）,43.62 % （325/745） and 37.83%（213/563） respectively.There were statistically significant differences in the 4 rates（P〈0.05）. Thus, the contamination of raw livestock and poultry meats by bacterial pathogens was severe in the 4 cities of Guangxi,in which were mainly contaminated by Salmonella, Staphylococcus aureus.Therefore, preventive measures should be strengthened to ensure the food quality and health of consumers.
