Abstract

Listeria monocytogenes is a human pathogen responsible for listeriosis, a sporadic but serious disease that poses significant health risks, particularly to vulnerable populations such as pregnant women, the elderly, and immunocompromised individuals. Mozzarella cheese, a widely consumed fresh dairy product, may represent as a potential vehicle for this pathogen, primarily due to the risk of post-processing contamination. This study presents a systematic review and meta-analysis aimed at estimating the prevalence of L. monocytogenes in mozzarella cheese at the end of the manufacturing process. The literature search identified 13 studies that met the predefined inclusion criteria from international citation databases. Additionally, 10 years of data were retrieved from an Italian laboratory database, covering mozzarella samples tested in Italy and 2 studies from gray literature. In total, 16 studies were analyzed using random-effects meta-analysis, and the pooled prevalence of L. monocytogenes in mozzarella was estimated at 1.2% (95% CI: 0.0-4.2) although a high heterogeneity among studies was observed (I2 = 78%). Despite the detection of the pathogen in some studies, the concentration levels were below the limit of quantification, implying low levels of contamination. The results confirm that L. monocytogenes can occur in mozzarella, typically due to post-stretching cross-contamination. The findings underline the importance of implementing effective hygiene practices and highlight the need for further predictive microbiology models tailored to mozzarella's unique properties to better assess the consumer exposure.

马苏里拉奶酪中单核细胞增生李斯特菌的流行:一项系统综述和荟萃分析。
单核细胞增生李斯特菌是一种导致李斯特菌病的人类病原体,李斯特菌病是一种散发但严重的疾病,对健康构成重大风险,特别是对孕妇、老年人和免疫功能低下个体等脆弱人群。马苏里拉奶酪是一种广泛消费的新鲜乳制品,可能是这种病原体的潜在载体,主要是由于加工后污染的风险。本研究提出了一项系统综述和荟萃分析,旨在估计马苏里拉奶酪在生产过程结束时单核细胞增生乳杆菌的流行情况。文献检索从国际引文数据库中确定了13项符合预定义纳入标准的研究。此外,从意大利实验室数据库中检索了10年的数据,包括在意大利测试的马苏里拉奶酪样品和灰色文献中的2项研究。总共有16项研究使用随机效应荟萃分析进行了分析,尽管观察到研究之间存在高度异质性(I2 = 78%),但马苏里拉奶酪中单核细胞增生乳杆菌的总患病率估计为1.2% (95% CI: 0.0-4.2)。尽管在一些研究中检测到病原体,但浓度水平低于定量限制,表明污染水平较低。结果证实,单核细胞增生乳杆菌可以发生在马苏里拉奶酪,通常是由于拉伸后交叉污染。这些发现强调了实施有效的卫生措施的重要性,并强调了进一步针对马苏里拉奶酪独特特性的预测微生物模型的需求,以更好地评估消费者的暴露程度。
