陕西省食品中沙门氏菌监测研究

目的了解陕西省食品中食源性致病菌沙门氏菌污染情况。方法 2002-2007年检测陕西省8个监测点的14类2 960份食品,采用现场调查与实验室分析相结合的方法。结果 2 960份食品中检出沙门氏菌污染230份,沙门氏菌检出率7.77%。其中生猪肉、生牛肉、生禽肉、生羊肉的沙门氏菌检出率分别为19.10%、21.93%、11.63%、16.59%;熟肉和水产类为检出率5.76%、3.83%;奶类、速冻米面等食品中未检出。在时间上,以2005年检出率最高,2007年最低。在空间上,陕北高于关中高于陕南(χ2=12.16,P<0.01);病原学鉴定分属11个血清群或亚群、28个血清型,发现了陕西省未曾报道的Q群和其他血清型沙门氏菌。结论要在努力把关生肉食品微生物污染的基础上,高度关注和严格控制熟肉食品的微生物污染,防止肉食品变质;根据关中、陕北人口密度高、流动性大的特征开展食品卫生工作,落实监管措施,防范新种群菌株的扩散,保障食品安全。
