Did Salmonella infection rates stay the same or increase in recent surveillance reports?
Data from the Foodborne Diseases Active Surveillance Network indicates that the incidence of infections caused by Salmonella stayed the same during 2019 1. While the overall rate did not rise, specific situations involving travel, food products, and pets have led to distinct outbreaks in recent years.
What the research says
A 2019 report found that Salmonella infection rates remained stable alongside Listeria and Shigella, even as other pathogens saw an increase 1. This suggests the general trend for Salmonella has been flat rather than increasing in the broad surveillance data.
However, specific strains and sources have caused notable outbreaks. Increases in human infections with a multidrug-resistant Salmonella Newport strain have been linked to travel to Mexico and consumption of U.S. beef products 3. Other recent events include a 2024 outbreak connected to ice used in coolers at a county fair in Illinois 7 and another in 2024 linked to household exposure to pet bearded dragons 8.
These specific incidents highlight that while the total number of cases may be stable, the sources of infection can vary significantly. Outbreaks have also been traced to cashew brie cheese 4 and contaminated charcuterie-style meats 5.
What to ask your doctor
- Have you ever been tested for Salmonella if I have traveled recently or eaten specific foods like beef or reptiles?
- What are the current signs of a Salmonella infection I should watch for?
- How can I reduce my risk of getting Salmonella from pets or travel?
- Are there specific Salmonella strains I should be aware of based on my recent activities?
