Ocorrência de Escherichia coli em meias carcaças de bovinos abatidos em estabelecimento habilitado para exportação.Ciência Rural, v.43, n.6, jun, 2013.

Suplementação com Saccharomyces cerevisae autolisada reduz contaminação microbiológica da carcaça de novilhos terminados em confinamento

“…Therefore, the most critical steps regarding contamination of bovine carcasses are skinning and evisceration, during which the skin and viscera can come into contact with the meat, carrying various pathogenic microorganisms (Brandão et al, 2012). Thus, the cattle husbandry system used, as well as the feeding approach, can minimize such contamination (Casagrande et al, 2012;Jardim et al, 2006).…”

“…According to Jardim et al (2006), animals from extensive rearing had greater amounts of dirt and microorganisms on the hide, which promoted greater contamination of the carcass after skinning when compared to feedlot animals. In contrast, Casagrande et al (2012) reported that confined animals subjected to a more energetic diet may harbor more generic E. coli in the gastrointestinal microbiota, which may contribute to greater contamination of the carcass by E. coli at the time of slaughter.…”
