REALPE-DELGADO, María Elena et al. Epidemiology of Salmonella spp., Listeria monocytogenes and Campylobacter spp., in the poultry chain production system. Iatreia [online]. 2016, vol.29, n.4, pp.397-406. ISSN 0121-0793.  https://doi.org/10.17533/udea.iatreia.v29n4a01.

Salmonella spp., Campylobacter spp., and L. monocytogenes are zoonotic foodborne pathogens, associated with the consumption of contaminated foods of animal origin. In this study we determined the prevalence and risk factors associated with the presence of these microorganisms at all stages of the production system, in two Colombian poultry companies (EI-EI-I and II). In EI-I, Campylobacter spp., and Salmonella spp., were isolated from 10 % and 4.4 % of the specimens, and S.

Heidelberg was the predominant serotype. Salmonella spp., was found in 6 % of hands and stool samples of workers. S. Saphra was the most prevalent serotype. In EIII, the prevalence of Campylobacter spp., and Salmonella spp., from animal specimens was 7 % and 17 %, respectively. L. monocytogenes was not detected. This study established the prevalence of these zoonotic pathogens through the production chain and showed the presence of pathogen carriers among workers/food handlers. ''Lack of medical examination of employees in the previous year'' was found to be a possible risk factor for carriage of Salmonella spp.
