Abstract
ABSTRACT Salmonella species have been isolated from various kinds of food and are accountable for outbreaks of foodborne diseases in humans. This study aimed at identifying the similarities between the DNA profiles of Salmonella isolated from chicken feces, chicken products, and human feces in southern Brazil. Six hundred samples were collected (200 from chicken products, 200 from broiler chicken feces, and 200 from human feces) and tested for the presence of Salmonella. Isolates proven to be Salmonella compatible by biochemical and serological tests were tested by the Polymerase Chain Reaction. Their DNA profiles were then analyzed by PFGE and rep-PCR. Salmonella was isolated from 16 out of 600 analyzed samples, with Schwarzengrund serotype presenting the highest incidence, followed by Mbandaka in chicken meat and fecal samples, and Panama in human fecal samples. Some strains isolated from chicken fecal and product samples were indistinguishable by the molecular methods used in the study, suggesting that that the contamination of the broilers on the farm can be transmitted the processed products.
Highlights
Food safety professionals try hard to prevent the growth of deteriorating and pathogenic microorganisms in food
Among the 200 chicken product samples analyzed from 16 different brands (A to P), 8 samples from 3 brands, A (5/80); L (2/18), and N (1/3), were contaminated with Salmonella: 3 from the liver, 3 from whole legs(brands A [2 samples] and L), 1 from whole wings,and 1 from the back.This low prevalence was reported by other authors
Salmonella is present in broiler chickens in southern Brazil, as well as in chicken products available for consumption, which represents a health risk for consumers
Summary
Food safety professionals try hard to prevent the growth of deteriorating and pathogenic microorganisms in food. Salmonella species have been isolated from various kinds of food and are accountable for outbreaks of foodborne diseases (FBD) in humans. The Centers for Disease Control and Prevention (CDC) estimate that FBD cause about 1.2 million cases of salmonellosis and about 450 deaths each year in the United States (CDC, 2015). In Brazil, between 2007 and 2014, 450 FBD outbreaks caused by Salmonella were reported, affecting 13,165 people (Portal Brasil, 2015). Among the different sources of contamination and transmission of Salmonella to humans, food products of poultry origin are the most frequently reported, and are mainly associated with consumption of undercooked poultry meat and/or products that were contaminated with raw poultry meat (Grant et al, 2016). The main source of contamination of chicken products is often the farm, where the occurrence of Salmonella is high (Kanashiro et al, 2005)
