How many food recalls are for salmonella each year?

The chart's answer: The FDA classified 77 food recalls for salmonella in 2025; the most since 2013 was 80 in 2016. Salmonella is a germ that causes food poisoning, often from eggs, produce, nuts, spices and pet food. A recall counts once however many products it covers, in the year FDA first listed it in its weekly Enforcement Report. Chartly sorted FDA's written reasons by their key words; a recall that names listeria too is counted on the listeria chart instead. Meat, poultry and most egg products are USDA's to recall and aren't included. The newest salmonella recalls, this year's included, are listed below.
