A viral egg trend on TikTok shows users freezing whole eggs in their shells, slicing them in half and frying them into tiny “mini eggs.” The method has gained millions of views across multiple waves on the platform, resurfacing again and again as new users discover the hack and try it for themselves. It looks satisfying — the miniature eggs make for eye-catching content — but the FDA and USDA are now warning that the trick can be dangerous and should not be attempted at home, citing food safety risks including potential salmonella exposure.
Here’s what food safety agencies want you to know before you try it.
Why Freezing Eggs in Their Shells Creates a Food Safety Problem
The FDA and USDA caution against freezing eggs in their shells, and the reason comes down to basic physics. Liquids expand when frozen. That expansion can cause eggshells to crack.
The cracks are the core of the problem. They don’t need to be visible to cause harm. According to agency guidance, even when cracks can’t be seen with the naked eye, they can compromise the egg’s protective barrier and allow bacteria to enter. An eggshell that appears fully intact on the outside may already be compromised in ways you can’t detect just by looking at it.
The agencies also note that freezing does not kill bacteria already present on or inside the egg. As a result, contaminated eggs may lead to foodborne illness, including salmonella. If bacteria were present before the egg went into the freezer, they survive the freezing process intact and remain a threat when the egg is later thawed, sliced and cooked.
What Salmonella Actually Does to Your Body
“Salmonella are a group of bacteria that can cause gastrointestinal illness and fever called salmonellosis,” per the FDA. 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 TikTok Videos Actually Show
Look closely at the viral TikTok videos promoting this trend and the food safety concerns become visible right on screen. Some of the clips show eggs coming out of freezers visibly cracked before being sliced and cooked. The shells have already fractured from the liquid expanding inside them — the exact issue that food safety agencies are warning about.
Commenters on the platform have raised concerns about the method as well. Some have referenced past versions of the trend and warned about earlier reports of food poisoning linked to similar behavior. The trend has resurfaced on TikTok after gaining millions of views in earlier waves, but the underlying food safety risks remain the same regardless of how many times the videos go viral or how many new users give the method a try.
How to Freeze Eggs Safely
Eggs can be frozen safely — but not in their shells. The FDA recommends cracking eggs first and freezing them in a freezer-safe container. They can be frozen either as scrambled whole eggs or as separated whites.
Here are the key guidelines from federal food safety agencies for anyone who wants to store eggs in the freezer the right way:
- Frozen eggs should be used within one year.
- To prepare frozen eggs for cooking, thaw them in the refrigerator overnight and cook immediately afterward.
- Thawing at room temperature is not recommended.
How Eggs Should Be Cooked to Reduce Salmonella Risk
Beyond proper storage, how you cook eggs also matters for food safety. USDA guidance states that eggs should be cooked until both yolks and whites are firm to reduce the risk of salmonella. The runny yolk that many people prefer does carry more risk than a fully cooked one.
Vulnerable groups — young children, pregnant people, elderly individuals and immunocompromised people — are advised to avoid runny or undercooked eggs altogether.
The frozen egg trend makes for eye-catching content on TikTok, but the food safety risks behind it are real and backed by warnings from both the FDA and USDA. If you want to freeze eggs for later use, skip the viral method. Crack the eggs out of their shells first, store them properly in a freezer-safe container and cook them thoroughly when you’re ready to eat.
