The objective of this study is to review from a bibliographical point of view the effects of Salmonella spp on laying hens, addressing its impact on avian health, egg quality and production, and the economic and public health repercussions. Salmonella is a bacteria of importance and zoosanitary surveillance, since it directly affects the productivity of laying hens through systemic infections and damage to their intestinal health, decreasing egg quality and increasing mortality rates, predisposing factors such as vertical transmission. and horizontal, stress from intense production and immunosuppressive diseases surely aggravate the problem. As a methodology, a methodological approach was used for the literature review based on an exhaustive search to identify relevant studies on the prevalence of Salmonella spp. The results show that the serovars S. enteritidis and S. typhimurium are the most frequent in laying hens, which poses a serious food safety problem due to contamination of both the exterior and interior of the eggs. It is concluded that this problem also corresponds to risks of Salmonellosis in humans and enormous economic losses for the poultry industry in terms of reduction in production, control costs and imposed regulatory sanctions, therefore, the proper management of Salmonella spp requires the application of comprehensive biosecurity strategies, control programs and preventive measures on farms.
Keywords: Prevalence, public health, zoonosis, poultry industry.
