Researchers trace 73% of US Salmonella cases to chicken and vegetables

Researchers used genome sequencing and machine learning to trace the top food sources behind Salmonella infections in the US. Chicken and vegetables emerged as the primary culprits, together accounting for up to 73% of human cases with known sources.

Machine learning links up to 64 percent of Salmonella cases to chicken and vegetables

A study by the CDC, FDA and USDA used whole-genome sequencing (WGS) and machine learning to identify chicken and vegetables as leading sources of Salmonella enterica infections in the United States. The research, published in the April 2025 issue of Emerging Infectious Diseases, focused on sporadic cases, which account for 95 percent of the Centers for Disease Control and Prevention’s estimated 1.35 million annual Salmonella illnesses. Since WGS…
