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.

Summary: From 2016 to 2019, three multistate outbreaks in the United States were suspected to be caused by dry bulb onions. In 2020, a large multistate outbreak of Salmonella Newport infections occurred in both the United States and Canada, and red onions were identified as the primary source. This was the largest recorded foodborne Salmonella outbreak in the United States, and it was resolved through international data sharing.

Summary: Poultry remains a significant source of foodborne salmonellosis, despite a significant reduction in Salmonella incidence during processing. Regional differences in Salmonella serovar prevalence were observed, and the limited detection depth of traditional culture techniques contributed to discrepancies between pre- and postharvest poultry. Accurately identifying all serovars present is crucial for assessing public health risk and implementing effective Salmonella controls.

Summary: Between May and September 2018, a multistate outbreak caused by an uncommon molecular subtype of Salmonella Mbandaka occurred in the United States. Out of 136 cases, 35 resulted in hospitalizations but no deaths were reported. Investigation revealed that 63 individuals had consumed or possibly consumed a specific sweetened puffed wheat cereal before falling ill.

Summary: This study used whole genome sequencing to investigate 37 Salmonella enterica strains isolated from human stool and contaminated foods in Brazil. The study identified 10 different semvars, various antimicrobial resistance determinants and plasmids among the strains, as well as the presence of virulence genes and plasmids. The findings highlighted virulence and antimicrobial resistance determinants in strains that may contribute to recurring food outbreaks.

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: The USDA FSIS does not have a zero-tolerance policy for Salmonella in poultry and poultry products, but has established performance standards for acceptable percentages of positive samples. The prevalence of Salmonella in poultry establishments is published for public viewing based on verification sampling results. Quantification using RT-PCR is proposed as a valuable method to determine the efficacy of interventions and make rapid food safety decisions.

Summary: A method was used to attribute US foodborne illnesses to specific food categories, with findings showing that Salmonella illnesses are mainly linked to seeded vegetables, eggs, and meats; E. coli O157 to beef and vegetables; L. monocytogenes to fruits and dairy; and Campylobacter to dairy and chicken. Further adjustments are recommended before using Campylobacter attribution estimates.

Summary: This study analyzed the genomic features of antimicrobial resistance and virulence potential in 105 non-Pullorum/Gallinarum Salmonella isolates recovered from dead poultry in Shandong, China. The isolates showed high antimicrobial resistance and harbored different critical virulence genes, highlighting the urgent need for effective strategies to mitigate avian salmonellosis.

Summary: Avian influenza is a contagious disease that causes high avian mortality, leading to economic losses and increased costs for disease control. It is caused by an RNA virus and only Influenzavirus A can infect birds. The pathogenicity of avian influenza is based on the lethality, signs, and molecular characteristics of the virus. Low pathogenic avian influenza has a low mortality rate, while highly pathogenic avian influenza can cross barriers and damage all tissues with a high mortality rate. The zoonotic potential of avian influenza has made it a global public health concern.

Summary: Salmonellosis is a major foodborne zoonosis in Europe, with poultry products as the main source of infection. The slaughterhouse has been identified as a potential source of Salmonella contamination in the poultry meat. A study was conducted to investigate a slaughterhouse with persistent Salmonella problems and found a high genetic relationship among Salmonella strains isolated during the slaughter process. It is necessary to implement molecular diagnosis methods at the field level to control Salmonella and prevent its entry into the slaughterhouse environment.

Summary: Controlling Campylobacter in poultry before harvest is crucial for reducing foodborne infections. This study evaluated the efficacy of pre-colonization with oxidative stress defense mutants in preventing Campylobacter colonization in chickens. The results showed that the ahpC and katA mutants significantly reduced C. jejuni colonization.

Summary: MB-1 is a attenuated infectious bursal disease virus vaccine. It was observed that the vaccine virus replicated with a temporal delay due to maternally derived antibodies (MDAs). The mechanism of its survival despite MDA neutralization remained unclear. After vaccination at 1 day of age, MB-1 virus penetrates and resides in local macrophages, which are then distributed to lymphoid organs. The ability of MB-1 to survive within macrophages ensures its survival during effective MDA protection.
