Is It Safe to Leave Eggs on the Counter?

Storing your eggs out on the counter isn't all it's cracked up to be. Keep reading to learn where you should be storing your eggs and why.

We’ve all been there: You either forgot to put the egg carton back in the fridge after whipping up an amazing breakfast or got distracted while putting away your grocery store haul. Whichever way, your eggs ended up staying on the counter way longer than you intended. So the question is, are they still any good?

Why it’s not safe

Unfortunately, eggs left out on the counter for more than two hours need to be tossed. This is because eggs are susceptible to salmonella contamination due to how they’re processed before they get to the grocery store. The same can’t be said for eggs in Europe.

Eggs can be contaminated with salmonella before they leave the farm, either because the hen is infected (the bacteria doesn’t make them sick) or the egg comes into contact with dirt and fecal matter after it’s laid. Due to this risk, the U.S. Food and Drug Administration requires egg farmers to thoroughly wash, dry, sanitize, and refrigerate eggs before they’re shipped off. This process removes any potential salmonella from the shell but does slightly thin it and removes some of its natural protection. So, the eggs are almost immediately refrigerated to prevent any new bacteria introduction (salmonella flourishes in temperatures between 40-140°F).

Once the eggs have been refrigerated, letting them sit unrefrigerated is a big no-no. Transferring eggs from your fridge to the kitchen counter can cause condensation on the eggshell. Water and warm temperatures are a breeding ground for salmonella, meaning the water on the eggshell exposes the egg to contamination. Even if the room-temperature eggs don’t have condensation on them, bacteria can still contaminate them through the thinned shell.

How long do eggs last?

When kept in a refrigerator at 40°F or lower, eggs can last up to five weeks as long as you keep your eggs in this part of the fridge. After those five weeks, air will have seeped through the shell and started to break down the yolk and white. To check if too much air has penetrated your eggs, try this simple trick, straight from Grandma. Find out if it’s really safe to eat expired eggs.
