I just signed up for emails from the FDA about recalls of foods and meds.  I expected a few each month.  I didn't expect a few each day, and it's not always about contamination or bacteria.

In foods, the recalls and warnings have mostly been that foods contain substances that they aren't supposed to have, e.g., sulfites or nuts, but also foods that aren't supposed to have any milk or wheat products in them and actually do have some.  Same with nuts and other things that can cause people to react.  So, if you think you reacted to a food, and it contains more than one ingredient, it's always possible it also contained something that's not on the label!

A lot of them appeared to have been products that might have been subject to cross-contamination with nuts, dairy, wheat, etc. during manufacturing.

If a recall isn't big news, you'd have to dig to find it.  If people are injured and if it's widespread, then it seems to make the front page.
