中文摘要: 摘 要:目的:分析2020—2024年德州市市售肉及肉制品主要致病微生物污染情况,为食品安全风险评估、预警提供
科学依据。方法:2020—2024年按照《山东省食品污染和有害因素风险监测手册》要求,在德州市11个县(市、区)对市
售肉及肉制品进行随机采样,5年共采集样本218份,对其进行沙门菌、单核细胞增生李斯特菌、蜡样芽孢杆菌等8种主要致
病微生物检测。结果:218份样本中检出致病微生物阳性样本88份,总阳性检出率为40.37%。其中,生禽肉污染严重,阳性
检出率高达71.43%(50/70),其余依次为生畜肉51.85%(14/27)、调理肉制品38.00%(19/50)、熟肉制品7.00%(5/71)。4种
肉类样品阳性检出率比较,差异有统计学意义(χ2
=62.37,P<0.05)。8种致病微生物中,单核细胞增生李斯特菌检出率最
高,为24.75%;其余依次为弯曲菌(19.26%,有5份样本同时检出结肠弯曲菌和空肠弯曲菌)、沙门菌(15.84%,包含15种
血清型,以肠炎沙门菌为主)、产气荚膜梭菌(4.42%)、致泻大肠埃希菌(3.52%)、小肠结肠炎耶尔森菌(3.40%,主要为
生物1A型)、蜡样芽孢杆菌(2.80%)、金黄色葡萄球菌(2.20%)。结论:2020—2024年德州市市售肉及肉制品存在不同程
度的食源性致病菌污染情况,引起食源性疾病的可能性很大,应引起有关部门重视。
