Chart 1 of 2 · Food and drug safety

How many food recalls are for salmonella each year?

The interactive chart needs JavaScript. The numbers are on the chart's page.

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.

Questions to discuss

  2. Find the biggest change or difference in the chart. What might explain it?
  3. Who collected these numbers, and how recent are they? What else would you want to know before drawing a conclusion?

Chart 2 of 2 · Crime

Which big U.S. cities have the most violent crime?

The interactive chart needs JavaScript. The numbers are on the chart's page.

In 2025, Memphis, TN had the highest violent crime rate of the 89 biggest U.S. cities whose police reported a full year to the FBI, about 1,853 per 100,000 people, followed by Detroit, MI (1,654) and Oakland, CA (1,475). Irvine, CA (79) and Virginia Beach, VA (101) had the lowest; the U.S. rate was about 330. Violent crime is murder, rape, robbery and aggravated assault. In 2025 the police in New Orleans, Orlando and St. Petersburg, Florida, didn't report a full year of crimes, so they are left out. 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 one big city's violent crimes reported to the FBI in a year (murder, rape, robbery and aggravated assault) for every 100,000 people its police department serves. The dashed line is the rate for the whole U.S. Dividing by population makes big and small cities fair to compare, but a city's rate also depends on where its borders fall.

Questions to discuss

  1. Find the city with the highest rate and the one with the lowest. About how many times higher is the top rate?
  2. Some departments police a whole county, suburbs included. How could that change a city's rate compared with one that covers only its downtown?
  3. These are crimes reported to police. What kinds of crime might never show up in these numbers, and why?
