So, despite these reports, there is not enough data about the occurrence of the disease in population and implied food.…”

An overview of Listeria monocytogenes contamination in ready to eat meat, dairy and fishery foods

Listeria monocytogenes is a relevant foodborne pathogen in public health, responsible for outbreaks of listeriosis often associated to the consumption of ready to eat meat, dairy and fishery products. Listeriosis is a serious disease that can lead to death and mainly affect children, the elderly and immunocompromised individuals. In pregnant women causes abortion or neonatal listeriosis. In Brazil, ready to eat food are appreciated and increasingly consumed by the population. Furthermore, products such as sausages, bologna, hams and cheeses have characteristics such as pH, Aw and sodium chloride content that favor the development of L. monocytogenes during their shelf life. The purpose of this paper was to present an overview of L. monocytogenes contamination in different meat, dairy and fishery products that are ready for consumption and thereby support the adoption of strategies to mitigate this risk, contributing to achieve the appropriate level protection for the consumers and thus strengthen Brazil's food safety system.

Molecular characterization and biofilm-formation analysis of Listeria monocytogenes, Salmonella spp., and Escherichia coli isolated from Brazilian swine slaughterhouses

et al. 2022

This study aimed to verify the presence of Listeria monocytogenes, Salmonella spp., and Escherichia coli in two Brazilian swine slaughterhouses, as well as to perform antibiograms, detect virulence and antimicrobial resistance genes, and evaluate the in vitro biofilm-forming capability of bacterial isolates from these environments. One Salmonella Typhi isolate and 21 E. coli isolates were detected, while L. monocytogenes was not detected. S. Typhi was isolated from the carcass cooling chamber’s floor, resistant to several antimicrobials, including nalidixic acid, cefazolin, chloramphenicol, doxycycline, streptomycin, gentamicin, tetracycline, and sulfonamide, and contained resistance genes, such as tet(B), tet(C), tet(M), and ampC. It also showed moderate biofilm-forming capacity at 37°C after incubating for 72 h. The prevalence of the 21 E. coli isolates was also the highest on the carcass cooling chamber floor (three of the four samplings [75%]). The E. coli isolates were resistant to 12 of the 13 tested antimicrobials, and none showed sensitivity to chloramphenicol, an antimicrobial prohibited in animal feed since 2003 in Brazil. The resistance genes MCR-1, MCR-3, sul1, ampC, clmA, cat1, tet(A), tet(B), and blaSHV, as well as the virulence genes stx-1, hlyA, eae, tir α, tir β, tir γ, and saa were detected in the E. coli isolates. Moreover, 5 (23.8%) and 15 (71.4%) E. coli isolates presented strong and moderate biofilm-forming capacity, respectively. In general, the biofilm-forming capacity increased after incubating for 72 h at 10°C. The biofilm-forming capacity was the lowest after incubating for 24 h at 37°C. Due to the presence of resistance and virulence genes, multi-antimicrobial resistance, and biofilm-forming capacity, the results of this study suggest a risk to the public health as these pathogens are associated with foodborne diseases, which emphasizes the hazard of resistance gene propagation in the environment.

“…Na Austrália, dados do período de 1997 a 2003 identificaram contaminação por L. monocytogenes em 4,7% dos produtos cárneos fatiados prontos para consumo, 1,2% em patês e 2,7% em salsichas (Ross et al, 2009). No Chile, em amostras analisadas entre 2008 e 2012 foi detectado L. monocytogenes em 5% das salsichas e produtos cárneos curados, 3% dos queijos e 3% dos produtos de pescado (Saludes et al, 2015 Entretanto, por serem frequentes os relatos de detecção deste microrganismo em diferentes alimentos comercializados no país (Petinatti et al, 2006;Rossi et al, 2011;Fai et al, 2011;Mendonça et al, 2012;Andrade et al, 2014;Ristori et al, 2014) bem como seu isolamento em pacientes hospitalizados, porém, sem associar ao consumo de um determinado alimento (Cruz et al, 2008;Martins et al, 2010;Reis et al, 2011), pode-se inferir que existe a possibilidade de não notificação de casos de listeriose humana no Brasil.…”
