What the numbers on your egg carton really mean – and why ignoring them can make you sick

You've seen it – probably a hundred times. That mysterious three-digit number stamped on the side of your egg carton. Perhaps you assumed it was a batch code, a price inquiry, or simply random packaging noise.

But this number? It is actually the best indicator of   the freshness of the eggs and food safety – and if you ignore it, that could be the reason why your quiche  left  everyone with an   uneasy feeling.

Let's decipher what these numbers really mean – and how to use them to avoid foodborne illnesses.

🔢 The three-digit number: It's the Julian date

This number (usually between   001 and 365  ) is the   Julian date  – the day of the year on which the eggs   were packed  .

  • 001   = January 1st

  • 032   = February 1st

  • 120   = April 30

  • 365   = December 31

So if your carton   says 120, the eggs were packed on  April 30th  , the 120th day of the year.

🥚   Important:   This is   not   the expiration date, but the   packaging date  .
