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.

Chart 2 of 2 · World

What is the unemployment rate in each country?

The chart's answer: In 2025, 4.2% of workers in the United States were unemployed, against 4.8% worldwide; the highest rate was 34.2% in Eswatini, and the lowest 0.1%, in Qatar. Search 182 countries and territories. These are the International Labour Organization's estimates, which count people without work who are looking for it and fill gaps where a country runs no regular survey, so they can differ from a country's own figures.
