Eggs pack more nutrients per calorie than the vast majority of other foods, and they are an inexpensive and delicious source of protein. It’s no wonder that they’ve become a breakfast staple, but if you’re thinking about cracking open an egg that’s past its expiry date, think again. Expired eggs are one of the most common causes of foodborne illness. Eating them can cause mild symptoms ranging from abdominal discomfort, gas and diarrhea to full-blown food poisoning.
In the United States, egg packing companies are not required by law to provide an expiry date, but they must stamp the date at which the eggs were packed onto every carton. If you store your eggs in the refrigerator, you can safely eat them for up to four weeks after they were packed. However, leave them any longer and you’ll be increasing your risk of upsetting your stomach or worse.
