Chart 1 of 2 · Food and drug safety

How many food recalls are for undeclared allergens each year?

Chart: How many food recalls are for undeclared allergens each year?

The FDA classified 190 food recalls in 2025 for an allergen left off the label, such as milk, peanuts, tree nuts, wheat, soy, eggs, fish, shellfish or sesame; the most since 2013 was 282 in 2017. From 2013 through 2025, undeclared allergens were the most common reason food was recalled. 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 for a germ as well counts under the germ. Meat, poultry and most egg products are USDA's to recall and aren't included. The newest allergen recalls, this year's included, are listed below.

Chart 2 of 2 · Crime

Which big U.S. cities have the highest murder rates?

Chart: Which big U.S. cities have the highest murder rates?

In 2025 St. Louis, MO had the highest murder rate of the 89 biggest U.S. cities whose police reported a full year to the FBI, about 51.3 per 100,000 people, followed by Memphis, TN (31.0) and Cleveland, OH (28.0). Irvine, CA (0.0) and Plano, TX (0.7) had the lowest; the U.S. rate was about 4.4. Departments that didn't report a full year are left out (for 2025, New Orleans, Orlando and St. Petersburg, Florida). Each rate is per person the department serves, and a few, such as Las Vegas, Honolulu, Jacksonville and Louisville, serve their whole county. A city's rate also depends on where its borders fall, so compare cities with care.

How to read this chart

Each bar is the number of murders in a city in one year for every 100,000 people its police department serves. The dashed line is the U.S. rate. Murders are rare, so in a smaller city a handful more or fewer in one year can move its rate and its rank a lot.

Questions

  1. How many cities on the chart have a murder rate above the U.S. rate, and how many are below it?
  2. Why does a chart like this use murders per 100,000 people instead of the total number of murders in each city?
  3. A city's rank can jump from one year to the next. Why might small numbers make rates bounce around?
