Viral Frozen Egg Trend on TikTok Prompts FDA and USDA Warnings About Salmonella Risk
If you have scrolled past the frozen egg trend on your feed, you might have been tempted to try it. A viral TikTok hack shows users freezing whole eggs in their shells, slicing them in half and frying them into tiny “mini eggs.” The method has resurfaced on the platform after gaining millions of views in earlier waves, but food safety agencies are now warning that the hack can be dangerous and should not be attempted at home.
The FDA and USDA caution against freezing eggs in their shells. For anyone who wants to understand the science behind that warning — not just take it at face value — the reasons are straightforward, rooted in how liquids behave at low temperatures and how eggshells function as a barrier against bacteria.
The Food Science: Why Shells Crack In the Freezer
The core issue is a basic physical property that applies to anything liquid you put in the freezer: liquids expand when they freeze. The contents of an egg — white and yolk — are mostly liquid. When those contents expand inside a rigid shell, the shell can crack.
Sometimes those cracks are obvious. Sometimes they are not. But according to FDA and USDA guidance, even when cracks are not visible, they can compromise the egg’s protective barrier and allow bacteria to enter.
An intact eggshell and the thin membrane beneath it serve as a natural defense against contamination. That barrier is what stands between the outside environment and the egg’s interior. Once it is breached — whether you can see the crack or not — bacteria have a direct path inside. That contamination can happen silently, without any visible sign to the person pulling the egg out of the freezer.
This is the central problem with the TikTok method. The trend involves freezing whole eggs in their shells and then slicing and cooking them. But by the time you slice into that frozen egg, the shell may have already cracked and allowed bacteria to pass through.
Freezing Does Not Kill Bacteria
A critical detail from FDA and USDA guidance: freezing does not kill bacteria already present. If salmonella or other pathogens were on or inside the egg before it went into the freezer, they survive the freezing process. As a result, contaminated eggs may lead to foodborne illness, including salmonella.
That means an egg that appeared fine before freezing could pose a health risk once the shell has cracked in the freezer.
According to the FDA, “Salmonella are a group of bacteria that can cause gastrointestinal illness and fever called salmonellosis.” While some individuals may not develop symptoms, others can become seriously ill.
The risk is higher for vulnerable groups, including children, older adults, pregnant people and those with weakened immune systems. Because of this, officials warn that the TikTok “mini fried egg” trend is especially unsafe for kids.
What the Viral Videos Actually Show
Some of the viral TikTok videos show eggs coming out of freezers visibly cracked before being sliced and cooked — the exact scenario the FDA warns against. Commenters on the platform have raised concerns, with some referencing past versions of the trend and warning about earlier reports of food poisoning linked to similar behavior.
The trend has resurfaced after gaining millions of views in earlier waves, and the agencies’ warning is direct: this hack should not be attempted at home.
Thawing and Cooking for safety
If you are meal-prepping or looking to preserve extras before they go to waste, there is good news. Eggs can be frozen safely — just not in their shells.
The FDA recommends cracking eggs first and freezing them in a freezer-safe container. You can freeze them as scrambled whole eggs or as separated whites. Removing the shell before freezing eliminates the risk of invisible cracks that could let bacteria reach the egg’s contents. This is the key difference between the TikTok method and the approach the FDA recommends.
Frozen eggs should be used within one year, giving you a wide storage window for planning ahead.
Thawing and Cooking for safety
When you are ready to use your frozen eggs, proper thawing matters just as much as proper storage. The FDA recommends thawing them overnight in the refrigerator and cooking them immediately afterward. Thawing at room temperature is not recommended.
USDA guidance states that eggs should be cooked until both yolks and whites are firm to reduce the risk of salmonella. Vulnerable groups such as young children, pregnant people, elderly individuals and immunocompromised people are advised to avoid runny or undercooked eggs altogether.
Whether you are working with fresh eggs or properly frozen ones, cooking them thoroughly remains the final safeguard against foodborne illness.
