Abstract

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.

牛肉中的李斯特菌：隐藏的风险

与沙门氏菌和大肠杆菌等其他病原体相比，牛肉中的单核细胞增生李斯特菌受到的关注较少。为了填补这一空白，我们对牛肉中存在的单增李斯特菌进行了文献综述。综述内容包括致病机制、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，单核细胞增生奈氏菌在牛肉和牛肉制品中的流行率从 2.5% 到 59.4% 不等。值得注意的是，血清型 4b 最常在食品加工过程中的牛肉污染案例中分离出来，而去皮和去内脏阶段被确定为污染的关键点。

期刊介绍： Research in Microbiology is the direct descendant of the original Pasteur periodical entitled Annales de l''Institut Pasteur, created in 1887 by Emile Duclaux under the patronage of Louis Pasteur. The Editorial Committee included Chamberland, Grancher, Nocard, Roux and Straus, and the first issue began with Louis Pasteur''s "Lettre sur la Rage" which clearly defines the spirit of the journal:"You have informed me, my dear Duclaux, that you intend to start a monthly collection of articles entitled "Annales de l''Institut Pasteur". You will be rendering a service that will be appreciated by the ever increasing number of young scientists who are attracted to microbiological studies. In your Annales, our laboratory research will of course occupy a central position, but the work from outside groups that you intend to publish will be a source of competitive stimulation for all of us."That first volume included 53 articles as well as critical reviews and book reviews. From that time on, the Annales appeared regularly every month, without interruption, even during the two world wars. Although the journal has undergone many changes over the past 100 years (in the title, the format, the language) reflecting the evolution in scientific publishing, it has consistently maintained the Pasteur tradition by publishing original reports on all aspects of microbiology.
