What the Numbers on Your Egg Carton Really Mean — And Why Ignoring Them Could Make You Sick

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.

🧪 Fact: Salmonella can be inside the egg before the shell forms—so washing the shell won’t help.

✅ How to Use the Julian Date Safely

Find the number on the short side of the carton (often near the USDA grade mark).

Calculate the pack date (use a Julian date converter online if needed).

Use within 3–5 weeks of that date.

When in doubt, toss it out—especially for dishes like quiche, hollandaise, or tiramisu that use undercooked eggs.
