摘　　要：目的了解广州市番禺区食品中大肠菌群污染情况,为食品卫生监管提供相关依据,以降低食源性疾病的发生率。方法采集2018—2019年广州市番禺区食品中208份样品进行菌落总数、大肠菌群计数的检测,并对检测结果进行统计分析。结果56.25%(117/208)的样品菌落总数≥10 CFU/g[mL],25.00%(52/208)的样品大肠菌群计数≥10 CFU/g[mL];样品产地为本市的样品中菌落总数≥10 CFU/g[mL]的占比为78.57%(88/112),大肠菌群计数≥10CFU/g[mL]的占比为37.50%(42/112);样品产地为国外的样品中菌落总数≥10CFU/g[mL]的占比为7.14%(4/56),大肠菌群计数≥10CFU/g[mL]的占比为7.14%(4/56);样品产地为本省它市的样品中菌落总数≥10CFU/g[mL]的占比为47.06%(8/17),大肠菌群计数≥10CFU/g[mL]的占比为11.76%(2/17);样品产地为省外的样品中菌落总数≥10CFU/g[mL]的占比为70.59%(12/17),大肠菌群计数≥10CFU/g[mL]的占比为5.88%(1/17);样品产地为港澳台的样品中菌落总数≥10CFU/g[mL]的占比为100.00%(2/2),大肠菌群计数≥10CFU/g[mL]的占比为0(0/2);样品产地为不详的样品中菌落总数≥10CFU/g[mL]的占比为75.00%(3/4),大肠菌群计数≥10 CFU/g[mL]的占比为75.00%(3/4);本市、国外、本省它市等不同样品产地的样品中菌落总数、大肠菌群计数的结果比较差异有统计学意义(P<0.05);2018年和2019年采集的样品中菌落总数的结果比较差异无统计学意义(P>0.05);2018年采集的样品中大肠菌群计数≥10 CFU/g[mL]的比例为32.95%,明显高于2019年的19.17%,差异有统计学意义(P<0.05)。结论2018—2019年广州市番禺区食品中大肠菌群污染情况比较严重,尤其是本市、本省它市区、不详等产地的食品,但2019年广州市番禺区食品中菌落总数、大肠菌群的污染情况有明显改善,有关部门应进一步加强对食品卫生的监管,并积极采取有效措施,有效预防并减少食源性疾病的发生。Objective To investigate the situation of coliform contamination in food in Panyu District,Guangzhou City,and to provide relevant basis for food hygiene supervision,so as to reduce the incidence of foodborne diseases.Methods A total of 208 samples of food in Panyu District,Guangzhou were collected from 2018 to 2019 for de-tection of total number of colonies and counts of coliform bacteria,and the detection results were statistically analyzed.Results 56.25%(117/208)had the total number of colonies≥10 CFU/g[mL],and 25.00%(52/208)had the coliform count≥10 CFU/g[mL];the proportion of the total number of colonies≥10 CFU/g[mL]in the samples from this city was 78.57%(88/112),and the proportion of coliform counts≥10 CFU/g[mL]was 37.50%(42/112);the proportion of the total number of colonies≥10 CFU/g[mL]in the samples from abroad was 7.14%(4/56),and the proportion of coliform counts≥10 CFU/g[mL]was 7.14%(4/56);the proportion of the total number of colonies≥10 CFU/g[mL]in the samples from other cities in the province was 47.06%(8/17),and the proportion of coliform counts≥10 CFU/g[mL]was 11.76%(2/17);the proportion of the total number of colonies≥10 CFU/g[mL]in samples from outside the province was 70.59%(12/17),and the proportion of coliform counts≥10 CFU/g[mL]was 5.88%(1/17);the proportion of the total number of colonies≥10 CFU/g[mL]in the samples from Hong Kong,Macao,and Taiwan was 100.00%(2/2),and the proportion of the coliform count≥10 CFU/g[mL]was 0(0/2);the proportion of the total number of colonies≥10 CFU/g[mL]in the samples of unknown origin was 75.00%(3/4),and the proportion of the coliform count≥10 CFU/g[mL]was 75.00%(3/4).The results of the total number of colonies and coliform counts in samples from differ-ent sample origins in this city,foreign countries,and other cities in this province were compared,and the differences were statistically significant(P<0.05).There was no significant difference in the total number of colonies between the samples collected in 2018 and 2019(P>0.05).The
