The “best before” is one of the first things we look for when picking items such as milk and eggs.
But be careful with this -. “Best before” may not be the best indicator of freshness when it comes eggs
The FDA does not require egg producers to mark their cards with a “best by” date-it is up to manufacturers to decide whether or not to do so.
The optional “best before” does not say how old the eggs can be. Instead, you should look at another label on the package, which is usually located below the “best before”.
This label includes a number, called the Julian calendar, which marks the day of the year in which the eggs were placed in the carton. For example, if the label contains the number 358, then the eggs were packed on December 24
This means that if you took an egg carton containing the Julian date of 358 on January 20, eggs would be at least twenty-six days of age.
It is important to note that the Inspection Service and Food Safety says that when cooled to forty-five degrees Fahrenheit, eggs should be good for four to five weeks after the date of Julian. As a result, regardless of what the “best” label may say, in the example given it is likely to take another week or more to use the eggs before they are damaged.
So if you’re buying eggs, look at the Julian date, and if it is more than forty days old, the best thing to do is take a different cardboard box.
