“…The other assessed matrices did not present high Enteritidis prevalence, at rankings of 2nd, 8th, and 10th in beef (Table S8) in Africa, Europe, and Asia, respectively, and 3rd in seafood in Africa and Asia (Table S9). Corroborating these results, several studies have confirmed poultry products as the main vehicles for Salmonella infection and unquestionably associated this with the Enteritidis serovar (20,(101)(102)(103)(104). According to Shah et al (105), the prevalence of the Enteritidis serovar in poultry products in the United States has increased from 0.45% in 2002 to 1.5% in 2012, suggesting that poultry meat is another major risk factor concerning human infection by this serovar.…”

Salmonella spp. are among the most important foodborne pathogens and the third leading cause of human death among diarrheal diseases worldwide. Animals are the primary source of this pathogen, and animal-based foods are the main transmission route to humans. Thus, understanding the global epidemiology of Salmonella serovars is key to controlling and monitoring this bacterium. In this context, this study aimed to evaluate the prevalence and diversity of Salmonella enterica serovars in animalbased foods (beef, pork, poultry, and seafood) throughout the five continents (Africa, the Americas [North and Latin America], Asia, Europe, and Oceania). The meta-analysis consisted of a chemometric assessment (hierarchical cluster analysis and principal component analysis) to identify the main epidemiological findings, including the prevalence and diversity of the Salmonella serovars in each matrix. Regarding the serovar distribution, S. Typhimurium presented a cosmopolitan distribution, reported in all four assessed matrices and continents; poultry continues to play a central role in the dissemination of the Enteritidis serovar to humans, and Anatum and Weltevreden were the most frequently found in beef and seafood, respectively. Additionally, we recommended careful monitoring of certain serovars, such as Derby, Agona, Infantis, and Kentucky. Finally, given the scientific data regarding the most frequently reported serovars and which matrices constitute the main vehicles for the transmission of this pathogen, control programs may be improved, and specific interventions may be implemented in an attempt to reduce the risk of this pathogen reaching humans. IMPORTANCE Salmonellosis is caused by Salmonella spp. and is the third leading cause of death among food-transmitted diseases. This pathogen is commonly disseminated in domestic and wild animals, and the infection's symptoms are characterized by acute fever, nausea, abdominal pain, and diarrhea. The animals are the primary source of salmonellae, and animal-based foods are the main transmission route to humans. Therefore, data collected from these sources could contribute to future global interventions for effective control and surveillance of Salmonella along the food chain. In light of this, the importance of our research is in identifying the prevalence of Salmonella serovars in four animal-based food matrices (pork, poultry, beef, and seafood) and to evaluate the importance that each matrix has as the primary source of this pathogen to humans.

“…58,59 Like E. coli, Salmonella is also a member of the Enterobacteriaceae family and has peritrichous flagella, making it motile. 60 Salmonella is composed of six subspecies containing over 2,700 serotypes, with more being discovered each year, all of which are presumed to be pathogenic. Salmonella accounts for approximately half of all produce-associated outbreaks in the United States.…”

This article provides a comprehensive literature review of the growing significance that foodborne pathogens have on the produce supply and the steps that are taken to reduce them. The numbers of illnesses that are caused by contaminated produce are rising steadily. Three of the most common pathogens that have been seen to cause significant illness in humans through produce are Escherichia coli, Salmonella spp. and Listeria monocytogenes. The antimicrobial interventions, practices and antimicrobials that are currently the most commonly used by the food industry are examined. The literature shows that these antimicrobials currently in use have significant drawbacks when it comes to their role in the produce industry. Sensitivities to temperature and organic load and the production of harmful by products are some of these drawbacks. There is a need for a new antimicrobial that can be used in the produce processing industry. One that maintains its efficacy through the temperature, pH, and organic load changes that are experienced during produce processing. Sodium acid sulfate is a potential contender for this role. It has not previously been used or extensively studied as an antimicrobial, but is already deemed generally recognized as safe (GRAS) product by the Food and Drug Administration (FDA). The use of an antimicrobial that can withstand the varying conditions that the produce industry constantly has is imperative to reducing the number of foodborne illness caused every year by contaminated produce.
