ABSTRACT
Campylobacteriosis has become common cause of diarrhea in humans and is associated with Guillain-Barré Syndrome, Reactive Arthritis and Irritable Bowel Syndrome is caused mainly by contaminated food and water intake in which the majority occurs from manipulation, preparation and consumption of poultry meat. The aim of this study was to estimate the prevalence of Campylobacter in chicken carcasses from slaughterhouses located in the states of Parana, Santa Catarina and Rio Grande do Sul in the South of Brazil. The samples were analyzed for Campylobacter enumeration using the ISO method 10272-2 and the species C. jejuni and C. coli, important for public health, were identified through Maldi-TOF mass spectrometry. From July 2017 to July 2018, 816 samples were analyzed, indicating the prevalence of 35.84%, with higher occurrence of C. jejuni (78.47%). No difference in prevalence was observed in relation to the size of the slaughterhouses. However, significant differences were noted among the three states in the southern region of the country, with the lowest prevalence being observed in Parana. The results reinforce the need to advance in the implementation of strategies to control this pathogen in the country, in order to safeguard consumer's health and contribute for the maintenance of Brazil's position in the international poultry meat market.

ABSTRACT: 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.
RESUMO: Listeria monocytogenesé um patógeno de importância em saúde pública por estar associado a surtos de listeriose, muitas vezes causados por produtos de origem animal prontos para o consumo. Listeriose é uma doença grave que pode levar ao óbito crianças, idosos e indivíduos imunocomprometidos. Em gestantes ocasiona aborto ou listeriose neonatal. No Brasil, os produtos de origem animal, prontos para consumo, são cada vez mais apreciados pela população. Eles, muitas vezes, podem ser ingeridos sem a necessidade de que o consumidor realize preparo prévio do alimento por meio de calor. Além disso, produtos como salsicha, mortadela, presunto e queijo possuem características como pH, Aw e teor de cloreto de sódio que favorecem o desenvolvimento de L. monocytogenes ao longo da vida de prateleira. Objetivou-se com este trabalho apresentar um panorama da contaminação por L. monocytogenes em produtos cárneos, lácteos e pescados prontos para consumo e, assim, auxiliar na adoção de estratégias para mitigar o risco, contribuindo para alcançar um nível adequado de proteção do consumidor e fortalecer o sistema de segurança alimentar brasileiro.
