QUESADA, Adriana et al. Antimicrobial resistance of Salmonella spp isolated animal food for human consumption. Rev. perú. med. exp. salud publica [online]. 2016, vol.33, n.1, pp.32-44. ISSN 1726-4634.

Objectives. To analyze all information available on antimicrobial-resistant Salmonella species isolated from foods of animal origin that are used for human consumption in Latin America. Materials and methods. A systematic review of observational epidemiological studies conducted in Latin America between 2003 and 2014 was carried out using the PubMed and LILACS databases. Studies conducted as part of analyses of outbreaks or cases of human infection were not included. Three reviewers independently participated in the study selection. Additionally, the studies included underwent quality assessment. Results. A total of 25 studies met the inclusion criteria. The studies included were conducted in Brazil, Mexico, Colombia, Argentina, and Venezuela. Salmonella spp. isolates were obtained mainly from animal-based foods derived from cattle, swine, and poultry, revealing that Salmonella typhimurium and S. enteritidis were the most frequently isolated serotypes (17 and 11 studies, respectively). In 23 studies, Salmonella spp. showed resistance to more than one antibiotic, including nalidixic acid, streptomycin, tetracycline, chloramphenicol, ampicillin, trimethoprim-sulfamethoxazole, gentamicin, ciprofloxacin, and cephalosporins. Conclusions. Salmonella spp. isolates obtained mainly from animal-based foods for human consumption in the countries analyzed often show resistance to several antibiotics. It is important that more countries in Latin America carry out and publish studies on Salmonella spp. resistance in order to establish and monitor adequate control strategies.
