How is the expiration date of eggs determined?

Answer 1

they only have so many weeks from the time that they are gathered or "harvested" . The date they are gathered is noted on their shipment from the egg farm... then when they go for sizing, inspection and packaging a machine prints out a date on the package that gives the expiration date for the eggs (so many weeks from time of harvest in temperature controlled settings) After that date the proteins and other various components of the eggs start to break down and deteriorate.. as happens with any organic item. Eggs that are slightly past their date should be fine to eat but might not taste as good as those that are fresher. They also do not hold together as well during cooking as fresher eggs.

Answer 2

noreen, egg farms collect eggs every day, so it's easy to determine what date the hen produced them. They use that date as the baseline for sell-by and use-by dates.

I've used eggs way, way past the use-by date dozens of times (we don't eat a lot of eggs) and never once had a rotten one. I do break them into a separate bowl one by one, so a bad egg can't 'contaminate' whatever I'm making, but so far, never gotten one.

Answer 3

I don't know,but all I know is I got deathly ill when I ate eggs that were past the expiration date.
I throw mine out as soon as the expiration date is passed,just like milk.
