摘　　要：目的了解2020年福建省生禽肉中沙门菌污染状况、血清分型和耐药情况。方法采集2020年福建省生禽肉样品178份,按照GB 4789.4—2016的方法分离出沙门菌后进行血清分型,并对分离出来的沙门菌进行药敏实验。结果共检出沙门菌40株,检出率为22.5%(40/178),通过血清分型,鼠伤寒沙门菌占比最高,检出率为22.5%(9/40),其次分别是肯塔基沙门菌和肠炎沙门菌,检出率分别为17.5%(7/40)、15.0%(6/40)。药敏实验结果表明,40株沙门菌对四环素耐药程度最高,耐药率为77.5%(31/40),其次是萘啶酸和氨苄西林,耐药率分别为62.5%(25/40)、52.5%(21/40)。多重耐药率(MDR>3)为52.5%(21/40)。结论2020年福建省生禽肉中存在一定程度沙门菌污染,以鼠伤寒沙门菌为主。菌株耐药状况严重,且存在较高的多重耐药率,应加强食品安全风险监测,预防食源性疾病暴发。Objective To investigate the contamination status,serotyping and antibiotic resistance of Salmonella in raw poultry meat in Fujian Province in 2020.Methods Salmonella was isolated from 178 raw poultry meat samples according to GB 4789.4—2016,serotyping and drug resistance experiments were performed on the isolated Salmonella.Results Forty strains of bacteria were detected,with a detection rate of 22.5%(40/178).By serotyping,Salmonella typhimurium accounted for the highest proportion with a detection rate of 22.5%(9/40),followed by Salmonella kentucky and Salmonella enteritidis with the detection rate of 17.5(7/40)and 15.0%(6/40),respectively.The results of drug resistance experiments showed that these 40 strains of Salmonella were most resistant to tetracycline with a resistance rate of 77.5%(31/40),followed by nalidixic acid and ampicillin with resistance rates of 62.5%(25/40)and 52.5%(21/40),respectively.The multiple drug resistance rate(MDR)was 52.5%(21/40).Conclusion There was a certain degree of contamination of Salmonella in the raw poultry in Fujian Province in 2020,which was mainly dominated by S.typhimurium.The situation of drug resistance was serious,and there was a high rate of multi drug resistance.Food safety risk monitoring should be enhanced to prevent the outbreaks of foodborne diseases.
