Listeria monocytogenes in beef receives less attention compared to other pathogens such as Salmonella and Escherichia coli. To address this gap, we conducted a literature review focusing on the presence of L. monocytogenes in beef. This review encompasses the pathogenic mechanisms, routes of contamination, prevalence rates, and the laws and regulations employed in various countries. Our findings reveal a prevalence of L. monocytogenes in beef and beef products ranging from 2.5% to 59.4%. Notably, serotype 4b was most frequently isolated in cases of beef contamination during food processing, with the skinning and evisceration stages identified as critical points of contamination.
与沙门氏菌和大肠杆菌等其他病原体相比，人们对牛肉中的李斯特菌关注较少。为了弥补这一空白，我们进行了一项文献综述，重点关注牛肉中李斯特菌的存在。本综述涵盖了致病机制、污染途径、流行率以及各国采用的法律法规。我们的研究结果表明，牛肉和牛肉制品中李斯特菌的流行率为 2.5%至 59.4%。值得注意的是，在食品加工过程中，4b 型血清型是牛肉污染中最常分离到的李斯特菌，剥皮和去内脏阶段被确定为污染的关键节点。
