Abstract

CARRASCAL-CAMACHO, Ana Karina et al. Occurrence of Salmonella spp in pork processing plants from Colombia: Systematic review and meta-analysis. Rev. investig. vet. Perú [online]. 2023, vol.34, n.6, e25111.  Epub Dec 31, 2023. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v34i6.25111.

A systematic literature review was carried out in Science Direct, PubMed, SciELO, EBSCO host, Redalyc, ProQuest and Google Scholar databases, followed by a metaanalysis to estimate the combined prevalence of Salmonella spp in pig carcasses in processing plants in the country. A total of 3007 scientific articles, technical reports, thesis works, and technical meeting presentations papers between 2009 and 2020 were collected. Those that did not meet the inclusion criteria were removed. Thus, 51 studies were reviewed in detail, selecting 11 documents that were used in the meta-analysis. The combined prevalence of Salmonella spp in pig carcasses was 9.7% (4.0-16.2%). The meta-analysis showed a high heterogeneity in prevalence. The low number of reports related to the prevalence of Salmonella in pork processing plants highlighted the need to study, monitor and report the presence of Salmonella spp to keep pathogen prevalence data updated due to its impact on public health.

Keywords : Salmonella spp; prevalence; pig slaughterhouse plants; Colombia.
