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

📅 How Long Are Eggs Safe to Eat?

According to USDA guidelines:

  • Raw eggs in the shell are safe for 3–5 weeks after the pack date

  • Eggs may still be safe even if the sell-by date has passed

  • Eggs should always be stored at 40°F (4°C) or below

⚠️ Critical tip:
The sell-by or best-by date helps stores manage inventory. The Julian date is what matters for safety and freshness.

🤢 Why Your Quiche Made Everyone Sick

Even if eggs look and smell perfectly fine, they can still contain Salmonella, a bacteria that causes:

  • Nausea

  • Vomiting

  • Abdominal cramps

  • Diarrhea

Salmonella does not change an egg’s appearance, smell, or taste.

It also isn’t destroyed by cracking, mixing, or baking unless the dish reaches a safe internal temperature.

  • Egg dishes must reach 160°F (71°C) to kill bacteria

  • A quiche that looks set may still be undercooked in the center

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