A Facebook post by Fresh Eggs Daily recently went viral after revealing how old grocery store eggs really are.
According to the website, the numbers under the “best by” date reveal how long ago the eggs were actually packaged.
The number, called the Julian Date, reveals the day of the year the eggs were packaged. The number on the label is between 1 and 365. If the number was 001, you’d know those eggs were packaged on January 1; if the number is 365, the eggs were packaged on December 31.
According to a video posted by Jared Stanley of J&J Acres, several stores were selling eggs that were packaged about 30 days earlier earlier. That date complies with federally mandated food safety standards, however many people who commented on social media say they had no idea the eggs were that old.
