![]() Director, North Carolina Layer Performance and Management Program. “There’s no way to know exactly what the exposure has been….therefore it’s deemed inedible.” “There’s too many variables to be able to say ‘I know exactly what happened to this egg and exactly when it started leaking and exactly what it’s been exposed to and exactly how it’s been handled,'” Jones said. So, when you’re staring down a leaker, and don’t know its fractured history, the best answer is “toss.” Sickened people might not even know what caused their issues. Of course, such illnesses would likely happen in isolation and would probably escape documentation. All bets are off when you find a significantly cracked egg in your cartonįood safety experts view the risks from “leaker” eggs as so clear-cut that I couldn’t find much research on the specific possible outcomes of eating them, aside from the salmonella risk. You’ll want to thoroughly cook it-either right away or within a couple days (keep it in a covered dish in the meantime). If you’re certain that the crack is fresh, then you can eat the egg, but with precautions. ![]() You have no way of knowing unless you’re positive that the break happened between the store and your home. However, in the egg pictured above, the dent suggests that the membrane was broken.Įven though nothing is leaking at the moment, North Carolina State University poultry specialist Ken Anderson pointed out some egg white could have leaked and then dried. What Jones calls a “thermal kill” should be sufficient. If it’s just a hairline crack and there’s no indication that the membrane has been broken, then you’ll want to make sure to cook the egg thoroughly (skip the runny yolk or hollandaise sauce). “It’s got everything they desire.” If an egg is cracked, but not leaking is it OK to eat? “The yolk is where they want to be because that’s like a spa day,” Jones said. If bacteria can overcome the egg’s natural barriers and arrive at the nutrient treasure trove of the yolk, they will start to proliferate like crazy. Such bacteria might normally be held off by the eggshell and membrane, as well as by chemical and structural defenses in the liquid egg white.īut exposure to air from a significant crack will cause the egg white to thin and its defenses to rapidly diffuse. While scientists studying eggs know that salmonella is the villain to beat (pun intended) in intact eggs, the field of potentially problematic invading bacteria expands considerably when you’re talking about a “leaker” egg.įor example, some bacteria generate sickening toxins that aren’t inactivated by heat. Since all eggs have a risk of salmonella bacteria, which is killed instantly at 165 degrees Fahrenheit or after several minutes at 145 degrees, you might think that simply cooking this egg would be enough.īut a hot oven or stovetop can’t protect you from the potential hazards of an egg like the one pictured above, Jones said. Even with thorough cooking a dented, cracked egg can be unsafe The USDA calls such eggs “leakers” and deems them inedible, said Jones, whose research center is part of the federal agency. National Poultry Research Center.Īnd if the membrane is broken as well, she said, “You have basically made this superhighway for anything to get in there. Jones, a research food technologist at the Egg Safety and Quality Research Unit of the U.S. “For microorganisms, a crack in an eggshell is like the Grand Canyon,” explained Deana R. In this egg, both its hard shell and the protective membrane just beneath appear to have broken, making the egg more vulnerable to invading bacteria. An egg with a large crack is more vulnerable to microbes But if you don’t know when the crack occurred, the egg could be contaminated and you should toss. If the egg was jostled at home or on your way back from the store, then fully crack it open into a dish, keep it covered in the fridge and use within two days. What it is: The dent suggests that both the shell and the egg’s membrane layer broke, making it easier for pathogens to enter.Įat or toss: This depends on when the crack occurred. What you see: A dented, cracked egg its contents may or may not appear to have spilled out.
