Why Your Quiche Made Everyone Sick

Even if eggs look and smell fine, they can harbor Salmonella—a bacteria that causes nausea, vomiting, cramps, and diarrhea.

Salmonella doesn’t change an egg’s appearance, smell, or taste.

And it’s not killed by cracking or mixing—only by proper cooking (to 160°F/71°C).

If your eggs were old, improperly stored, or from a contaminated batch, even a baked quiche might not have reached a high enough internal temperature to kill the bacteria.
