Summary: From May to mid-August 2021, there was an outbreak of Salmonella Typhimurium infections in Ontario, Canada, with 38 patients affected. Investigation revealed that the outbreak was linked to consumption of ready-to-eat seasoned tofu from multiple Ontario restaurants. The unsanitary conditions and insufficient heating of the tofu during production were identified as possible causes of the outbreak. The Canadian Food Inspection Agency issued a food recall for the affected tofu.

Summary: From May to mid-August 2021, a Salmonella Typhimurium outbreak occurred in Ontario, Canada, linked to consumption of seasoned tofu from a specific manufacturer. Investigations revealed unsanitary conditions and insufficient heating during production as potential causes of cross-contamination and pathogen survival. Tofu was identified as a novel outbreak-associated food vehicle for S. Typhimurium.

Summary: In 2020, there was an outbreak of Salmonella Newport infections in the United States linked to melons from southwest Indiana, resulting in 80 ill persons and 18 hospitalizations reported across 15 states. The investigation was unable to determine whether the vehicle for the infections was cantaloupe alone or both cantaloupe and watermelons. This outbreak highlights the need for further efforts to identify the source and extent of environmental contamination in the melon growing region and promote farm practices to reduce pathogen contamination of melons.

Summary: The sale and distribution of small turtles as pets have been banned in the United States since 1975 due to the risk of Salmonella transmission. However, outbreaks of salmonellosis continue to occur, particularly among children, linked to contact with small turtles. A recent investigation revealed the sale of small turtles from pet stores and identified a single turtle supplier to these stores.

Summary: This study conducted a retrospective investigation into a community outbreak of typhoid fever in Lanling, China in 2016. The genomic analysis showed that the Salmonella Typhi isolate from drinking water was responsible for the outbreak, with a high similarity to the isolates from patients in terms of genomic content, virulence gene profiles, and antimicrobial resistance gene profiles. Pulsed-field gel electrophoresis confirmed that these isolates were clonal variants. Furthermore, phylogeographical analysis suggested that the outbreak isolates were evolutionarily linked to isolates from the United Kingdom and Vietnam.

Summary: Studies on outbreaks of COVID-19 showed that contamination from frozen seafood packaging could be a potential source of infection, highlighting the importance of considering the risks of virus transmission through cold chain goods. Countries should implement various measures to prevent the introduction of the virus via imported goods.

Summary: Poultry feed is a major source of Salmonella infection in poultry in Switzerland. Organic feed is typically only treated with organic acids, and the detection of the same type of Salmonella in both Italy and Switzerland suggests a potential outbreak risk.

Summary: This study investigated a zoonotic outbreak of Salmonella Typhimurium infection in Australia in 2020. The investigation identified contact with live poultry as a common risk factor, and traced the outbreak to backyard poultry exposure and potential contamination in produce/pet stores. This is the first documented widespread outbreak of zoonotic salmonellosis in Australia caused by backyard poultry exposure.
