Chart 1 of 3 · Food and drug safety

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.

Each point is the number of people alive in the world in the middle of that year, estimated by the United Nations. The axis starts at zero, so the height of the line shows the true size. Look at how steep the line is to see how fast the population grew.

Questions

1. Judging from the chart, about how many years did it take the world to add its most recent billion people?
2. Is the line getting steeper or flatter in recent years? What does that tell you about the growth rate?
3. These numbers are estimates that the UN revises. Why is it hard to count every person on Earth?

2. Did the share grow faster in some years than others? What could have sped it up?
3. Using the internet once in three months counts here. What does this number leave out about how people get online?
