Salmonella enterica Serotypes Isolated from Imported Frozen Chicken Meat in the Canary Islands

Abstract

To determine the prevalence of Salmonella enterica serotypes in imported frozen chicken meat, 406 samples (whole chicken, legs, and breast meat) were analyzed for Salmonella according to ISO6579 rules, serotypes were assigned, and phage typing was conducted for Salmonella serotypes Enteritidis, Typhimurium, and Heidelberg. The overall frequency of Salmonella isolation was 16.5%. By country of origin, the highest percentage of cases was found among the samples from France followed by samples from Brazil. The differences between legs and breast meat were significant. The most frequently isolated serotype of Salmonella was Enteritidis, followed by Salmonella Heidelberg, Salmonella Typhimurium, and Salmonella Virchow. By country of origin, we identified a large percentage of serotype Salmonella Enteritidis in the samples imported from Brazil. There was a greater diversity of serotypes isolated from the French samples, and Salmonella Enteritidis was not the dominant strain. In the samples from the United States, the only serotype isolated was Salmonella Kentucky, although a smaller number of samples was analyzed. The Salmonella Enteritidis phage type that prevailed in both France and Brazil was 4. Phage types 204c and 204 were identified for Salmonella Typhimurium, and phage types 8, 31, and 37 were identified for Salmonella Virchow.

Evolution of the iss Gene in Escherichia coli

“…The recent emergence of Salmonella serovar Kentucky strains among poultry and the strains' presence among cattle and swine and their presence within retail meats have been reported without plausible explanation (4,26,36,37,41,42,45,52,55,59). However, recent genome sequencing efforts have identified the ColV plasmid as a component of the genome of a multidrug-resistant Salmonella serovar Kentucky isolate (GenBank accession no.…”

Prevalence and Characterization of Multidrug-Resistant (Type ACSSuT) Salmonella enterica Serovar Typhimurium Strains in Isolates from Four Gosling Farms and a Hatchery Farm

“…In poultry, S. enterica serovar Typhimurium appeared to have a superior invasion capability compared to S. enterica serovar Gallinarum (11). Therefore, S. enterica serovar Typhimurium has been frequently found in young chickens, imported frozen chickens, ducklings, and geese in different countries (6,18,20,25,26,28,30). Although S. enterica serovar Typhimurium may not be a primary cause of disease, it could possibly cause septicemia in young ducklings with complications of other diseases (18).…”

“…Since the discovery of a multidrug-resistant ACSSuT S. enterica serovar Typhimurium DT104 strain in United Kingdom (35), this strain has spread around the world, and it is prominently distributed in Europe and Northern America (17,20), is less dispersed in Asia, such as in Korea (39) and Japan (32), and causes gastroenteritis and occasional outbreaks in human and wild or domestic animals. Type ACSSuT S. enterica serovar Typhimurium DT104 isolates not only have been frequently found in human (13) but have been commonly found in geese in the present study (Table 2).…”

Multidrug resistant Salmonella sp isolated from chicken

“…Since Salmonella infection could be systemic, isolating Salmonella from the trachea of the birds is possible. In previous reports Salmonella had been isolated from the tissue, lungs, liver gastrointestinal tract of the infected birds (Hernandez et al, 2005). Salmonella in poultry is traceable to the poultry feeds and water, as well as the hygiene of the poultry (environmental factor) and sometimes from humans (Roy et al, 2006).…”
