“…Although S. Typhimurium and S. Enteritidis are still the most prevalent Salmonella serotypes in the global health arena (Campos et al, 2012;Luvsansharav et al, 2020), their prevalence in recent years in the argentine broiler industry has been relatively low (circa 4.5%). (Caria, 2017).…”

“…Luvsansharav et al developed a new measure to determine the foodborne relatedness of serotypes by calculating the ratio of proportion of laboratory-confirmed infections caused by each serotype to the proportion of foodborne illnesses associated with each serotype in the recorded outbreaks. Serotypes Saintpaul, Heidelberg and Berta showed the highest foodborne relatedness among the top 20 serotypes in the US; whereas, serotypes Mississippi, Bareilly, and Paratyphi B variant L(+) tartrate(+) had the lowest relatedness (8). Infection with S. Newport, the third most common serotype in the US, has been considered to be linked with both the food pathway and environmental sources, such as creek water and sediment (9).…”

Non-typhoidal Salmonella enterica infections cause a high disease burden in the United States with an estimated 1.2 million illnesses annually. The state of Florida consistently has a relatively high incidence compared to other states in the United States. Nevertheless, studies regarding the epidemiology of nontyphoidal salmonellosis and its spatial and temporal patterns in Florida were rarely reported. We examined the spatial and temporal patterns of 62,947 salmonellosis cases reported to FL Health Charts between 2009 and 2018. Dominant serotypes circulating in Florida were also explored using whole genome sequencing (WGS) based serotype-prediction for 2,507 Salmonella isolates sequenced by the Florida Department of Health during 2017 and 2018. The representativeness of laboratory-sequenced isolates for reported cases was determined by regression modeling. The annual incidence rate of salmonellosis decreased from 36.0 per 100,000 population in 2009 to 27.8 per 100,000 in 2016, and gradually increased in 2017 and 2018. Increased use of culture-independent testing did not fully explain this increase. The highest incidence rate was observed in children, contributing 40.9% of total reported cases during this period. A seasonal pattern was observed with the incidence peaking in September and October, later than the national average pattern. Over these 10 years, the Northeast and Northwest regions of the state had higher reported incidence rates, while reported rates in the Southeast and South were gradually increasing over time. Serotypes were predicted based on WGS data in the EnteroBase platform. The top-five most prevalent serotypes in Florida during 2017–2018 were Enteritidis, Newport, Javiana, Sandiego and Braenderup. The highest percentage of isolates was from children under 5 years of age (41.4%), and stool (84.7%) was the major source of samples. A zero-inflated negative binomial regression model showed that the reported case number was a strong predictor for the number of lab-sequenced isolates in individual counties, and the geospatial distribution of sequenced isolates was not biased by other factors such as age group. The spatial and temporal patterns identified in this study along with the prevalence of different serotypes will be helpful for the development of efficient prevention and control strategies for salmonellosis in Florida.

“…The majority of clinical cases of salmonellosis transmitted by food are associated with specific Salmonella serovars. Luvsansharav et al (33) reported on a novel method for determining the strength of serotype association with foodborne transmission called a foodborne relatedness measure based on U.S. public health data. These authors found that Salmonella serotypes Saintpaul, Heidelberg, and Berta had the highest foodborne relatedness measures followed by the next three most prevalent serotypes: Enteritidis, Typhimurium, and Newport.…”

Salmonella Enteritidis is responsible for a significant proportion of foodborne Salmonellosis in the United States and continues to be attributable to table eggs, despite increased federal oversight in recent years. Technologies, including feed additives, continue to be evaluated for pre-harvest application of their potential food safety benefits. Here, Diamond V Original XPC™, a Saccharomyces cerevisiae fermentation based postbiotic (SCFP), was evaluated for its effectiveness in the reduction of Salmonella Enteritidis (SE) colonization in young layer pullets. A total of forty, day-old Hy-Line W-36 layer pullets were equally divided and randomly assigned to one of two dietary treatments with SCFP, or without (PCON) and orally gavaged on Day 28 with 10 6 CFU/mL of SE. Another twenty, day-old layer pullets were fed the same control feed without SCFP and blank inoculated on Day 28 with 1 ml of sterile PBS to serve as a negative control (NCON). Qualitative and quantitative analyses of cecal Salmonella contents were performed for all birds on Day 32. The prevalence of SE in the ceca of all directly challenged birds was 100%, however, the SE concentration in birds fed SCFP diet (3.35 Log 10 CFU/g) was significantly lower ( P <0.0001) than that of the PCON birds not fed SCFP (4.49 Log 10 CFU/g). Moreover, the proportion of SE colonized individuals with enumerable SE concentrations was lower in SCFP fed birds (57.9%) when compared to the PCON (95.0%). These data suggest that inclusion of SCFP in the diet may aid in the reduction of SE within the ceca of commercial laying hens and could serve as an additional, pre-harvest food safety hurdle.
