广东省2016–2019年市售畜禽肉产品中空肠弯曲菌污染状况分析
目的 分析2016~2019年广东省市售畜禽肉产品中空肠弯曲菌的污染状况。方法 于2016~2019年在广东省21地市采集畜禽生肉样品872份样品。采用GB 4789.9-2014《食品安全国家标准 食品微生物学检验 空肠弯曲菌检验》对空肠弯曲菌进行检测并对污染状况进行分析。结果 872份畜禽肉产品中, 空肠弯曲菌检出率为6.77% (59/872)。按照肉的种类分析, 禽肉检出率11.2% (46/410)高于畜肉检出率2.81% (13/462), 两者差异有统计学意义(?2=24.3301, P<0.05); 按年份分析, 2018年检出率最高11.48%(31/270), 其次是2016年10.71%(15/140), 2017年3.19%(9/282), 2019年检出率最低2.22%(4/180), 4者差异有统计学意义(?2=24.5797, P<0.05); 按包装形态分析, 散装检出率6.94%(59/850)高于预包装检出率0%。按季度, 空肠弯曲菌检出率高低依次为第二季度(8.21%, 18/219); 按采样环节分析, 网店空肠弯曲菌检出率(16.67%, 1/6)最高; 按地区分析, 深圳市空肠弯曲菌检出率最高37.21%(16/43)。结论 广东省市售畜禽肉产品中空肠弯曲菌存在较高比例, 禽肉中比例更高, 散装禽畜肉存在较大风险, 建议相关部门针对性加强对畜禽产品市场的监管及风险监测工作。
Objective To analyze the contamination status of Campylobacter jejuni in meat products sold in Guangdong province from 2016 to 2019. Methods From 2016 to 2019, totally 872 samples of livestock and poultry raw meat were collected from 21 cities in Guangdong province, and GB 4789.9-2014 National food safety standard-Microbiological examination-Campylobacter jejuni test was used to detect Campylobacter jejuni and analyze the pollution status. Results The detection rate of Campylobacter jejuni in 872 meat products was 6.77%(59/872). According to the analysis of meat types, the detection rate of poultry meat was 11.2% (46/410), higher than that of livestock meat 2.81% (13/462), and the difference was statistically significant (χ2=24.3301, P<0.05). According to the year analysis, the highest detection rate was 11.48% (31/270) in 2018, followed by 10.71% (15/140) in 2016, 3.19% (9/282) in 2017, and the lowest detection rate 2.22% (4/180) in 2019, and the difference was statistically significant (χ2=24.5797, P<0.05). According to the analysis of packaging form, the detection rate in bulk was 6.94% (59/850) higher than that in prepackage 0%. According to the quarter, the detection rate of Campylobacter jejuni was in the second quarter (8.21%, 18/219). According to the sampling procedure, the detection rate of Campylobacter jejuni was the highest in online stores (16.67%, 1/6). According to the regional analysis, the detection rate of Campylobacter jejuni in Shenzhen was the highest 37.21% (16/43). Conclusion There is a high proportion of Campylobacter jejuni in livestock and poultry meat products sold in Guangdong province, and a higher proportion in poultry meat, and there is a big risk in bulk poultry and livestock meat. It is suggested that the relevant departments strengthen the supervision and risk monitoring of the market of livestock and poultry products.
