摘要
目的了解食品和公共场所(简称饮服)从业人员沙门菌携带和血清分型情况,为科学防控食源性疾病提供依据。方法依据WS/T454-2014《从业人员预防性健康检查沙门菌、志贺菌检验方法》,对2017-2019年玉林城区饮服从业人员健康检查肛拭标本进行增菌、分离培养、生化及血清分型鉴定,并对沙门菌检出情况及携菌人群进行分析。结果 2017-2019年共采集肛拭标本122 340份,检出沙门菌2 845株,检出率2.33%,各年度检出率分别为2.32%、2.36%、2.30%;秋季检出率最高3.29%,春季检出率最低0.74%,四季间沙门菌检出差异有统计学意义(χ^(2)=370.609,P<0.05);沙门菌感染以20<30岁年龄段最高3.12%,40<50岁年龄段率最低1.64%,各年龄段沙门菌检出差异有统计学意义(χ^(2)=222.336,P<0.001);不同行业、性别间沙门菌检出差异无统计学意义(P>0.05)。沙门菌检出以B菌群占比最大31.88%,其次C1菌群19.19%,E1菌群居三15.99%,F菌群占比最小仅0.07%。前5位的沙门菌血清型依次为鼠伤寒沙门菌10.51%、科瓦利斯沙门菌9.74%、里森沙门菌9.35%、阿贡纳沙门菌7.98%、德尔卑沙门菌5.59%。结论玉林市饮服从业人员沙门菌血清分型多样化,B菌群占比最大,鼠伤寒沙门菌、科瓦利斯沙门菌占优,秋季和20<30岁年龄段沙门菌检出居多,应加强健康体检和卫生监管,预防食源性疾病发生。
Objective To understand the Salmonella carriage and serotyping of employees in drinking service,and provide basis for scientific prevention and control of foodborne diseases. Methods According to WS/T454-2014“Preventive Health Check for Practitioners Salmonella and Shigella Inspection Methods”,the 2017-2019 health check specimens of employees in the beverage and clothing industry in Yulin city were enriched,and the pathogens were isolated and cultured for the biochemical analysis and serotyping. The detection status of Salmonella and the population carrying the bacteria were analyzed. Results A total of 122 340 anal swab samples were collected,and 2 845 strains of Salmonella were detected,with a detection rate of 2.33%. The annual detection rates of 2017-2019 were 2.32%,2.36% and 2.30%,respectively;the highest detection rate was 3.29% in autumn and the lowest detection rate was 0.74% in spring. There was a significant difference in the detection rate of Salmonella among the four seasons(χ^(2)=370.609,P<0.05). The highest rate of Salmonella infection was 3.12% in the 20~<30 age group,and the lowest rate was 1.64% in the 40~<50 age group. The difference was statistically significant among different age groups (χ^(2)=222.336,P<0.001);there was no significant difference between different industries and genders(P>0.05). Salmonella group B accounted for the largest 31.88%,followed by group C119.19%,group E1 15.99%,and group F accounted for the smallest 0.07%. The top five Salmonella serotypes were Salmonella typhimurium 10.51%,Salmonella kovaris 9.74%,Salmonella reesen 9.35%,Salmonella agonna 7.98%,Salmonella delpi 5.59% in turn. Conclusions The serotypes of Salmonella among drinking service employees in Yulin city were diversified,and group B accounted for the largest proportion. Salmonella typhimurium and Salmonella kovaris were dominant. Salmonella were mostly detected in autumn and 20~<30 age groups. Health examination and health supervision should be strengthened to prevent food borne diseases.
