“…The contact surface is also considered one of the sources of cross‐contamination. Escherichia coli and Listeria monocytogenes were isolated from conveyor belts in four Brazilian broiler slaughterhouses (Viana et al., 2020). These sources lead to cross‐contamination and affect the shelf life and quality of the final product.…”

The environment in poultry abattoirs is the primary potential source of bacterial contamination and cross-contamination of broiler carcasses. In this context, we explored the influence of chilling water and contact surfaces on the microbial diversity of broiler carcasses in warm and cold seasons. Highthroughput sequencing was used to target the V3-V4 region of the 16S rRNA gene.Proteobacteria was the main phylum detected in broiler carcasses and on contact surfaces, whereas Bacteroidetes and Firmicutes had high abundances of the prechilling water in both seasons. At the genus level, Psychrobacter and Acinetobacter were much more abundant on broiler carcasses in the warm season, while Flavobacterium and Psychrobacter dominated in the cold season. LEfSe analysis showed that the chilling tank was a key location where carcass contamination occurred. Therefore, the risk of carcass contamination can be reduced by improving sanitary conditions during processing, installing longer chilling tanks, or increasing the water exchange rate in chilling tanks. The results of this study may be useful for better slaughterhouse environmental hygiene management in different seasons. Practical Application: This study will help poultry processing managers better understand the impact of different seasons on the environmental microbiota in the environment and their abundance in poultry processing plants, thus allowing them to adopt proper disinfection strategies for different seasons and environments, further improving the safety and shelf life of products.

“…is the primary cause of foodborne infections in Brazil as well as the world. Listeria monocytogenes is closely related to industrial environments, especially those in which the cleaning of surfaces and utensils is deficient (Brasil, 2018b; González et al, 2019 ; Melero et al, 2019 ; Viana et al, 2020 ).…”

The aim of this study was to evaluate the hygienic-sanitary quality of lamb meat sold in the city of Uruguaiana, Rio Grande do Sul (RS) by counting the indicator microorganisms and detecting pathogens such as Salmonella spp. and Listeria monocytogenes. Thirty-nine lamb meat samples were collected from 10 commercial establishments in Uruguaiana. The samples were subjected to counts of aerobic mesophilic microorganisms and enterobacteria, and to the detection of Salmonella spp. and L. monocytogenes, all following standard methods. The average counts of mesophilic microorganisms and enterobacteria were 6.08 log CFU/g (minimum 4.07 and max 6.87) and 4.73 log CFU/g (minimum 0 and max 5.88), respectively. For pathogens, L. monocytogenes was isolated from five samples (12.82%), with three samples in the same location. Only two samples (5.13%) were positive for Salmonella spp. The results demonstrated unsatisfactory hygienic-sanitary conditions because high counts of pathogens such as Salmonella spp. and L. monocytogenes. The counts of enterobacteria showed poor hygiene conditions during the various stages of production. The results also indicated fecal contamination, as Salmonella spp. and L. monocytogenes are present in the intestinal tract of both humans and animals. The high count of mesophilic microorganisms obtained could be owing to contaminated raw material or unsatisfactory processing, including unsanitary conditions and the inappropriate use of binomial time/temperature during storage.
