      【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≥10 CFU/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≥10 CFU/g[mL]的占比为 7.14% (4/56)，大肠菌群计数≥10 CFU/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≥10 CFU/g [mL]的占比为 47.06% (8/17)，大肠菌群计数≥10 CFU/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≥10 CFU/g [mL]的占比为 70.59% (12/17)，大肠菌群计数≥10 CFU/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≥10 CFU/g [mL]的占比为 100.00% (2/2)，大肠菌群计数≥10 CFU/g[mL]的占比为 0 (0/2)；样品产地为不详的样品中菌落总数≥10 CFU/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。

【Abstract】 Objective To investigate the situation of coliform contamination in food in Panyu District, Guang-zhou City, and to provide relevant basis for food hygiene supervision, so as to reduce the incidence of foodborne diseas-es. 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 coliformcount ≥10 CFU/g [mL]; the proportion of the total number of colonies ≥10 CFU/g [mL] in the samples from this citywas 78.57% (88/112), and the proportion of coliform counts ≥10 CFU/g [mL] was 37.50% (42/112); the proportion ofthe total number of colonies≥10 CFU/g [mL] in the samples from abroad was 7.14% (4/56), and the proportion of coli-form counts≥10 CFU/g [mL] was 7.14% (4/56); the proportion of the total number of colonies≥10 CFU/g [mL] in thesamples 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 provincewas 70.59% (12/17), and the proportion of coliform counts ≥10 CFU/g [mL] was 5.88% (1/17); the proportion of thetotal 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 colo-nies≥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 differenceswere statistically significant (P<0.05). There was no significant difference in the total number of colonies between thesamples collected in 2018 and 2019 (P>0.05).
