You\u2019ve seen it\u2014probably a hundred times. That mysterious three-digit number stamped on the side of your egg carton. Maybe you thought it was a batch code, a price lookup, or just random packaging noise.
\nBut that number? It\u2019s actually your best clue to freshness and safety\u2014and ignoring it could be why your quiche left everyone feeling \u201coff.\u201d
\nLet\u2019s decode what those numbers really mean\u2014and how to use them to avoid foodborne illness.
\nThe Three-Digit Number: It\u2019s the Julian Date!
\nThat number (usually between 001 and 365) is the Julian date\u2014the day of the year the eggs were packed.
\n001 = January 1
\n032 = February 1
\n365 = December 31
\nSo if your carton says \u201c120\u201d, the eggs were packed on April 30 (the 120th day of the year).
\nImportant: This is NOT the expiration date\u2014it\u2019s the pack date.
\nHow Long Are Eggs Safe to Eat?
\nAccording to the USDA:
\nRaw eggs in the shell are safe for 3\u20135 weeks after the pack date\u2014even if the \u201csell-by\u201d date has passed.
\nAlways refrigerate eggs at or below 40\u00b0F (4\u00b0C). Room temperature drastically shortens shelf life.
\nCritical tip: The \u201csell-by\u201d or \u201cbest-by\u201d date on the carton is not a safety cutoff\u2014it\u2019s for store inventory. The Julian date is what matters.

Why Your Quiche Made Everyone Sick<\/p>\n
Even if eggs look and smell fine, they can harbor Salmonella\u2014a bacteria that causes nausea, vomiting, cramps, and diarrhea.<\/p>\n
Salmonella doesn\u2019t change an egg\u2019s appearance, smell, or taste.<\/p>\n
And it\u2019s not killed by cracking or mixing\u2014only by proper cooking (to 160\u00b0F\/71\u00b0C).<\/p>\n
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.<\/p>\n
Fact: Salmonella can be inside the egg before the shell forms\u2014so washing the shell won\u2019t help.<\/p>\n
How to Use the Julian Date Safely<\/p>\n
Find the number on the short side of the carton (often near the USDA grade mark).<\/p>\n
Calculate the pack date (use a Julian date converter online if needed).<\/p>\n
Use within 3\u20135 weeks of that date.<\/p>\n
When in doubt, toss it out\u2014especially for dishes like quiche, hollandaise, or tiramisu that use undercooked eggs.<\/p>\n

Marking<\/p>\n
What It Means<\/p>\n
Grade AA, A, or B<\/p>\n
Quality (AA = firmest whites, roundest yolks)<\/p>\n
\u201cOrganic\u201d<\/p>\n
Hens fed organic feed, no antibiotics, outdoor access<\/p>\n
\u201cCage-Free\u201d<\/p>\n
Hens not in cages\u2014but may still be indoors<\/p>\n
\u201cPasture-Raised\u201d<\/p>\n
Hens roam outdoors (most humane, best nutrition)<\/p>\n
Plant code (e.g., P-1234)<\/p>\n
Identifies the farm (can be traced in recalls)<\/p>\n
