This Is How Long Eggs Last in the Fridge

Although eggs have been a common kitchen staple since the dawn of time, you may not know everything about this protein-packed ingredient, including how long they last in the fridge.
According to a CNET survey, 93% of Americans are concerned about inflation, and 77% are experiencing "sticker shock" when shopping for groceries. If you're considering buying eggs in bulk to save money or simply want to stretch that carton in your fridge for as long as possible, we have you covered.
We spoke to a food safety expert to explain the best way to store eggs so that you can enjoy them at their best, no matter when you decide to use them.
How long do eggs last in the fridge?
According to the US Department of Agriculture, eggs typically stay good for three to five weeks in the fridge. They "often remain safe to eat for a week or two beyond that date, as long as they've been kept refrigerated," said Zachary Cartwright, a member of the Food Safety and Quality Management Division at the Institute of Food Technologists and lead food scientist at Aqualab by Addium.
There are ways to maximize an egg's freshness. Cartwright says you should keep your eggs in their original carton and "with the pointed end down to help maintain their freshness by keeping the air cell at the top. This slows moisture loss and keeps the yolk centered."
It's also important to store eggs in the coldest part of your fridge rather than the door since the temperature fluctuates in that area, he says. Hard-boiled eggs that are still in their shell stay good for about a week in the fridge, according to the USDA.
Why do we refrigerate eggs?
The USDA recommends that eggs from a hen be stored in the fridge as soon as possible."In the U.S., eggs must be refrigerated due to the washing process that removes the natural protective coating on the shell, making them more susceptible to bacteria," Cartwright says. "In some other countries, eggs are not refrigerated because they retain their protective coating. However, once eggs are refrigerated, they should remain so to prevent condensation, which can promote bacterial growth."
According to State Food Safety, the U.S. washes its eggs to prevent the spread of salmonella. The USDA also recommends that eggs from a hen be stored in the fridge as soon as possible after they are gathered.
Can I freeze eggs?

Yes, but not in their shells. One option for freezing eggs is to crack them and then beat them together before storing them. Or you can freeze the egg yolks and whites separately. According to the USDA, the whites are more optimal for freezing because the texture stays the same, but if you want to freeze the yolks, you'll need to add salt and corn syrup or sugar to help with the consistency. Individual eggs can be frozen separately in ice cube trays and muffin pans, and they can stay frozen for up to one year.
You can also cook scrambled eggs or egg bites and store them in the freezer for two to three months. Although eggs can spoil, they often stay fresh much longer than you'd think.
How to test egg freshness
If you want to check if your eggs are still good before you crack them, you can perform a simple float test with your egg and a glass of cold water.
First, fill a large glass with cold water, then gently drop the egg inside. If the egg sinks and turns to its side, it's still perfectly good to eat. If the egg sinks, but stays upright, it's also still OK to eat, but it is an older egg and should be used soon. If the egg floats straight to the top of the water, that's your sign that it has gone bad and should be thrown away.
The egg float test: The egg on the right has spoiled, according to experts."This test works because air builds up inside the egg as it ages, making it more buoyant," Cartwright says.
One important thing to remember about the egg test is that if one of the eggs in the carton passes the test, that doesn't mean all of them will. Individually test each one before cooking it and pay attention to the smell after you crack the egg open. "A strong, sulfur-like odor is a clear sign the egg has gone bad," Cartwright says.
Something else to look out for is "unusual coloring, such as a pink, green or iridescent hue in the egg white or yolk, which can indicate bacterial contamination," Cartwright adds.
Is the best by date on eggs accurate?
It's best to keep your eggs stored in their original carton.Cartwright says that the best by date on eggs is "a guideline, not a strict rule," adding that eggs are often good for one to two weeks after the date printed on the carton, as long as they've been refrigerated.
"As eggs age, their quality diminishes -- they may lose some firmness, and the whites might become thinner -- but they can still be safe to eat," he says.

Brands brace for a MAHA food fight

Steak 'n Shake, a chain best known for milkshakes paired with burgers, is not exactly the first food that comes to mind that would comport to the tenets of wellness championed by the 'Make America Healthy Again,' or MAHA movement. MAHA supporters, led by Health and Human Services Secretary Robert F. Kennedy, Jr., agitate for 'clean' ingredients, cutting out sugar and saying no to food dyes and seed oils, among other things. Yet Steak 'n Shake has managed to earn the health secretary's blessing after announcing it would shift to using beef tallow — a MAHA favorite — to fry its food. This spring, it even mounted at least one pop-up lunch day at HHS headquarters, according to signs seen by CNN in the building. Major food and agricultural groups are publicly positioning themselves as fans of the MAHA movement, with brands of all stripes rushing to seize this moment for change as Kennedy draws up plans to reshape American food policy. By August, the secretary aims to issue the second installment of a sweeping plan, ordered by President Donald Trump, to tackle the causes of chronic illnesses in the country. The first report laid the groundwork for Kennedy's targets: environmental toxins, certain medications, and a whole lot of processed food. This second stage will lay out what HHS and other agencies plan to do about it. On top of that, Kennedy has also pledged new, slimmed-down dietary guidelines in line with this vision, also due out this summer — another change for food companies to furrow their brows over. But even as food and consumer advocates and their lobbyists jockey for a say, access and results have been highly mixed. Some are girding themselves for chilly receptions. 'I'm not going to say that there's no opportunity,' one consumer advocacy group executive, who asked not to be named amid the sensitive discussions, put it. But the secretary 'has been out there on a lot of unproven theories over the years,' the person said, 'and we're skeptical that our views will be taken seriously.' Food and agricultural groups were already put on guard when President Trump issued an executive order in February demanding a new approach to health in America. The order established the 'MAHA Commission,' which would advise the president on 'how best to exercise his authority to address the childhood chronic disease crisis.' In his capacity as HHS secretary, Kennedy was tapped to lead it and pulled together its first report laying out the main culprits, in their estimation, driving chronic diseases in the country. The specter of industry crackdowns that the report promised to bring set off a flurry of efforts to court Kennedy and his MAHA allies. As Kennedy was preparing the report, the National Oilseed Processors Association and the Edible Oil Producers Association, representatives of seed oil makers, each hired new lobbyists. The American Beverage Association, the trade group for major brands like Coca-Cola and PepsiCo, spent over $1 million in Washington, DC, lobbying the first few months of this year, up from $710,000 in the same period of 2024 according to public filings compiled by CNN. But it seems these overtures have so far only had limited success. This month, oilseed processors wrote a letter to Kennedy complaining that they, along with soybean and corn farmers, ranchers and other farming groups, have had no dialogue with HHS about the first MAHA report, which they argued had many flaws — or about what could come in the next installment. The lack of traction is, perhaps, unsurprising. Kennedy has railed against perceived influence that industry groups have over the agencies that regulate their products. The initial MAHA report specifically called out government lobbying across various industries, noting that more than 60% of lobbyists were formerly federal employees. Other major brands have gone the route of publicly stepping up the message of their alignment with the MAHA movement. Of its beef tallow switch, Steak 'n Shake said in February that their fries were being 'RFK'd!' The fast-food chain states on their website that fries, onion rings and chicken tenders are now fried in 100% beef tallow but other changes, like altering bread bun recipes to remove seed oils, will take more time. Last week Kraft Heinz, one of the country's biggest food manufacturers, said it would begin to phase out artificial food dyes currently in popular products like Heinz Ketchup, Crystal Light, Jell-O, and Kool-Aid. 'It is in our DNA to continuously renovate and innovate to make sure that we stay relevant and bring value to our consumers,' a Kraft Heinz spokesperson told CNN. And when Starbucks CEO Brian Niccol met with Kennedy this month, he shared, as the secretary put it, the coffee chain's plan to 'further MAHA its menu.' Regarding this, a Starbucks spokesperson told CNN it aims to let customers make 'informed nutritional decisions with transparency on ingredients, calories, and more. Plus, we keep it real — no high fructose corn syrup, artificial dyes, flavors, or artificial trans-fats.' The voluntary moves to align with MAHA goals seem to have at least earned those brands public praise from Kennedy. Brewing alongside this is a separate longtime Kennedy priority: changing the nation's dietary guidelines. The federal guide, which currently runs 164 pages, is used by everything from schools to doctors' offices to determine what students eat, what patients are recommended and what can be bought on food stamps. Kennedy has repeatedly said he wants the document to be chopped down to 'four page(s)' of plain language that is easy for parents, nurses and schools to use and that the update will also be delivered this summer. The current guide, Kennedy told reporters in April, 'looks like it was written by the food processing industry.' Yet it's not all up to Kennedy. The dietary guidelines are a joint project between HHS and the US Department of Agriculture, which also oversees vast parts of America's food systems and nutrition programs. The jurisdictions of the two agencies is not straightforward and can be at times downright confusing. For example, the Food and Drug Administration or FDA, a part of HHS, regulates health standards for sandwiches, but the USDA oversees the standards for open-face meat sandwiches. FDA oversees meat products made from bison, antelope, squirrels, opossums, rabbits, and an array of wild poultry but, USDA has control over farm and factory-raised ducks, geese, chicken, and other domestic poultry. Wild duck and geese food safety, on the other hand, are still managed by the FDA. USDA oversees most livestock meat products while the FDA regulates fish — except catfish. That fish officially moved over to USDA's purview in 2016, after domestic catfish farmers lobbied Congress for more safety oversight. Importantly, USDA is also in charge of the Supplemental Nutrition Assistance Program, or SNAP, which provides food stamps to low-income Americans. Kennedy has campaigned for barring Americans from using food stamps to buy soda and candy, triggering backlash from industry groups including the American Beverage Association — which pointed out SNAP isn't part of the HHS secretary's job. All this would make the situation seem ripe for conflict. The health and agriculture agencies 'have a huge overlap,' but previous clashes have usually been about food safety issues, said Marion Nestle, a New York University professor emerita, and author of the book 'Food Politics.' 'It's never been a problem before, because nobody's ever tried to do anything like this before,' she said, referring to the large-scale reforms Kennedy is proposing. Amid these overlapping factors and interests, some lobbyists think they can find better luck with the USDA and its secretary Brooke Rollins, according to people familiar with discussions. She has already sought to reassure farmers and food manufacturers who objected to the first MAHA report that its finding were not final. 'There's no doubt that we could do better on the next report, and my commitment is to do everything I can to ensure that our 'Ag' community is better represented,' Rollins told the House Agriculture Committee this month. Rollins, a longtime Trump ally who grew up on a Texas farm, is 'savvy' when it comes to navigating Kennedy's MAHA goals, said one person familiar with the discussions. 'She's not gonna let somebody roll her over if she really cares about it.' CNN has reached out to HHS and the USDA for comment.

Why crash test dummies used in car safety tests are still modeled after men

Maria Weston Kuhn had one lingering question about the car crash that forced her to have emergency surgery during a vacation in Ireland: Why did she and her mother sustain serious injuries while her father and brother, who sat in the front, emerge unscathed? 'It was a head-on crash and they were closest to the point of contact,' said Kuhn, now 25, who missed a semester of college to recover from the 2019 collision that caused her seat belt to slide off her hips and rupture her intestines by pinning them against her spine. 'That was an early clue that something else was going on.' When Kuhn returned home to Maine, she found an article her grandma had clipped from Consumer Reports and left on her bed. Women are 73% more likely to be injured in a frontal crash, she learned, yet the dummy used in vehicle tests by the National Highway Traffic Safety Administration dates back to the 1970s and is still modeled almost entirely off the body of a man. A survivor becomes an activist Kuhn, who is starting law school at New York University this fall, took action and founded the nonprofit Drive US Forward. Its aim was to raise public awareness and eventually encourage members of Congress to sign onto a bill that would require NHTSA to incorporate a more advanced female dummy into its testing. The agency has the final word on whether cars get pulled from the market, and the kind of dummy used in its safety tests could impact which ones receive coveted five-star ratings. 'It seems like we have an easy solution here where we can have crash test dummies that reflect an average woman as well as a man,' Sen. Deb Fischer, a Nebraska Republican who has introduced the legislation the past two sessions, told The Associated Press. Senators from both parties have signed onto Fischer's 'She Drives Act,' and the transportation secretaries from the past two presidential administrations have expressed support for updating the rules. But for various reasons, the push for new safety requirements has been moving at a sluggish pace. That's particularly true in the U.S., where much of the research is happening and where around 40,000 people are killed each year in car crashes. Evolution of a crash test dummy The crash test dummy currently used in NHTSA five-star testing is called the Hybrid III, which was developed in 1978 and modeled after a 5-foot-9, 171-pound man (the average size in the 1970s but about 29 pounds lighter than today's average). What's known as the female dummy is essentially a much smaller version of the male model with a rubber jacket to represent breasts. It's routinely tested in the passenger seat or the back seat but seldom in the driver's seat, even though the majority of licensed drivers are women. 'What they didn't do is design a crash test dummy that has all the sensors in the areas where a woman would be injured differently than a man,' said Christopher O'Connor, president and CEO of the Farmington Hills, Michigan-based Humanetics Group, which has spent more than a decade developing and refining one. A female dummy from Humanetics equipped with all of the available sensors costs around $1 million, about twice the cost of the Hybrid used now. But, O'Connor says, the more expensive dummy far more accurately reflects the anatomical differences between the sexes — including in the shape of the neck, collarbone, pelvis, and legs, which one NHTSA study found account for about 80% more injuries by women in a car crash compared to men. Such physical dummies will always be needed for vehicle safety tests, and to verify the accuracy of virtual tests, O'Connor said. Europe incorporated the more advanced male dummy developed by Humanetics' engineers, the THOR 50M (based on a 50th percentile man), into its testing procedures soon after Kuhn's 2019 crash in Ireland. Several other countries, including China and Japan, have adopted it as well. But that model and the female version the company uses for comparison, the THOR 5F (based on a 5th percentile woman), have been met with skepticism from some American automakers who argue the more sophisticated devices may exaggerate injury risks and undercut the value of some safety features such as seat belts and airbags. A debate over whether more sensors mean more safety Bridget Walchesky, 19, had to be flown to a hospital, where she required eight surgeries over a month, after a 2022 crash near her home in Sheboygan, Wisconsin, that killed her friend, who was driving. While acknowledging the seat belt likely saved her life, Walchesky said some of the injuries — including her broken collarbone — were the result of it pinning her too tightly, which she views as something better safety testing focused on women could improve. 'Seat belts aren't really built for bodies on females,' Walchesky said. 'Some of my injuries, the way the force hit me, they were probably worsened.' The Alliance for Automotive Innovation, an industry trade group, said in a statement to the AP that the better way to ensure safety — which it called its top priority — is through upgrades to the existing Hybrid dummy rather than mandating a new one. 'This can happen on a faster timeline and lead to quicker safety improvements than requiring NHTSA to adopt unproven crash test dummy technology,' the alliance said. Humanetics' THOR dummies received high marks in the vehicle safety agency's early tests. Using cadavers from actual crashes to compare the results, NHTSA found they outperformed the existing Hybrid in predicting almost all injuries — including to the head, neck, shoulders, abdomen and legs. A separate review by the Insurance Institute for Highway Safety, a research arm funded by auto insurers, was far more critical of the dummy's ability to predict chest injuries in a frontal crash. Despite the vast expansion in the number of sensors, the insurance institute's testing found, the male THOR dummy was less accurate than the current Hybrid dummies, which also had limitations. 'More isn't necessarily better,' said Jessica Jermakian, senior vice president for vehicle research at IIHS. 'You also have to be confident that the data is telling you the right things about how a real person would fare in that crash.' The slow pace of changing the rules NHTSA's budget plan commits to developing the female THOR 5F version with the ultimate goal of incorporating it into the testing. But there could be a long wait considering the THOR's male version adopted by other countries is still awaiting final approval in the U.S. A 2023 report by the Government Accountability Office, which conducts research for Congress, cited numerous 'missed milestones' in NHTSA's development of various crash dummy enhancements — including in the THOR models. Kuhn acknowledges being frustrated by the slow process of trying to change the regulations. She says she understands why there's reluctance from auto companies if they fear being forced to make widespread design changes with more consideration for women's safety. 'Fortunately, they have very skilled engineers and they'll figure it out,' she said.
