Salmonella spp. is responsible for severe foodborne disease, and is one of the main agents involved in foodborne outbreaks worldwide. Contamination occurs mainly as a result of poultry and egg consumption since they can carry some serotypes pathogenic to humans. The aim of the study was to evaluate the persistence and pathogenic potential of Salmonella spp. (n = 40) isolated from poultry slaughterhouse mats, using adhesion and invasion assays, antimicrobial susceptibility by disc diffusion, and biofilm production as phenotypic tests and genotypic analyses. Polystyrene mats presented 3.2 times greater chance of isolating Salmonella than canvas mats. Besides, we observed resistance to tetracycline (17.5%), ampicillin (10%), cefotaxime (7.5%), trimethoprim-sulfamethoxazole (5%), and chloramphenicol (2.5%). All strains possessed the invA, sipB, sipD, ssaR, sifA, sitC, iroN, tolC, flgK, fljB, and flgL genes. The genes sopB and sipA were both present in 92.5% of the isolates, while sopD and spvB were observed in 90% and 32.5% of strains, respectively. All strains adhered to and invaded HeLa cells. Regarding biofilm production, 31 (77.5%) strains were able to produce biofilm on polystyrene microplates. Using PFGE, we detected the persistence of clones in the environment for up to 18 fromthe 20 weeks. The ability of these strains to produce a biofilm and thus persist in the environment and disperse through contact surfaces in the processing plant favors the contamination of food, aggravated by the pathogenic potential of these isolates demonstrated by their adhesion capacity, invasion and resistance to various antibiotic agents.
Single-aged caged layer hen flocks were monitored for Salmonella over the course of their lifetime. Chicks from both flocks were Salmonella negative at hatch and remained negative during rearing. Pullets were transported to production farms at 15 weeks of age. Pre-population dust swabs collected from both production sheds had a high percentage of Salmonella positive samples (80 and 90%). Flocks were sampled at regular intervals until 70-72 weeks of age. The proportion of Salmonella positive samples and mean load detected on eggs was low on both farms. Analysis of dust samples revealed that Salmonella persisted in dust over 8 weeks. Dust total moisture content and water activity appears to influence bacterial persistence. On egg grading equipment, only suction cups prior to egg washing were Salmonella positive (mean proportion Salmonella positive samples 0.13 ± 0.07; mean load of 18.6 ± 12.31 MPN/ml). An egg washing experiment demonstrated that while washing reduced the total Salmonella load from eggshell surfaces, no effect was observed for shell pores. These results demonstrate that despite environmental contamination on farm, Salmonella contamination of eggs is low and is further minimized by washing.
In developing countries like Myanmar, there are lack of food safety practices and policies regarding the food storage, handling, and farmer education. The current study indicates the different storage methods for peanut kernels at farm level and their influence on prevalence of fungi. The study will give a deep insight to the policy makers to design food safety practices at farm level and educate the farmers to adopt the better practices to assure the consumer health and satisfaction in developing countries.
Officials with the Public Health Agency of Canada and the various provinces report continuing to investigate an outbreak of Salmonella infections.
Based on the investigation findings to date, exposure to raw turkey and raw chicken products has been identified as the likely source of the outbreak.
As of December 18, 2019, there have been 126 confirmed cases of Salmonella Reading illness investigated in the following provinces and territories: British Columbia (31), Alberta (44), Saskatchewan (8), Manitoba (24), Ontario (8), Quebec (2), New Brunswick (1), Prince Edward Island (1), Northwest Territories (1), and Nunavut (6). Individuals became sick between April 2017 and November 2019. Thirty-eight individuals have been hospitalized. One individual has died.

FDA continues to actively investigate the cause of this outbreak. An investigation team consisting of staff from FDA, CDC, the California Department of Public Health and the California Department of Food and Agriculture are attempting to identify any factors that could have led to contamination at a common farm identified by traceback. This investigation involves assessing and sampling soil, animal droppings, compost, water, and other potential environmental sources at the ranches of this grower. The samples and information collected during the farm investigations will be analyzed.
The Wisconsin Department of Health Services recently reported that they identified the outbreak strain of E. coli O157:H7 in an unopened bag of Fresh Express brand Leafy Green Romaine collected from an ill person’s home. The source of the romaine identified in the bag was Salinas, California. It was determined that one of the growers of this product also supplied romaine linked to other E. coli outbreaks that FDA is investigating.
These outbreaks are each caused by strains that are different from each other and different from the larger outbreak. One of the additional outbreaks, in Washington state, is potentially linked to romaine lettuce. The other outbreak, with cases in the U.S. and Canada, is linked to Fresh Express Sunflower Crisp Chopped Salad Kits.
