How to Store Eggs in Refrigerator

Eggs are a kitchen essential — and one of the most debated foods when it comes to refrigeration. In the US, refrigerating eggs is standard practice and essential for food safety. Here's everything you need to know about how to store eggs in the refrigerator correctly.

Why Do Americans Refrigerate Eggs?

In the United States, commercially produced eggs are washed and sanitized before sale, which removes the natural protective coating (called the "bloom" or cuticle) on the shell. Without this coating, eggs are porous and susceptible to bacterial contamination — particularly Salmonella. Refrigeration slows bacterial growth and is required by the USDA for commercially sold eggs.

Note: In many European countries, eggs are not washed and retain their bloom, making room-temperature storage safe. This guide covers US-standard refrigerated eggs.

Where to Store Eggs in the Refrigerator

Not on the door — on a main shelf. The refrigerator door is the warmest, most temperature-variable spot in the fridge due to frequent opening. Eggs need a consistent cold temperature. Store them on a main shelf, ideally toward the back where it's coldest.

How to Store Eggs in the Refrigerator

Keep in the original carton — The carton serves two important purposes: it protects eggs from absorbing strong odors through their porous shells, and it keeps them from losing moisture. Don't transfer eggs to the fridge door egg tray.
Store pointy end down — This keeps the yolk centered and away from the air cell at the wide end, which helps maintain freshness.
Keep away from strong-smelling foods — Eggs absorb odors easily through their shells. Store away from onions, garlic, and pungent cheeses.
Maintain temperature at 40°F (4°C) or below — Consistent cold temperature is key.

How Long Do Eggs Last in the Refrigerator?

Fresh whole eggs in shell: 3–5 weeks from purchase (check the sell-by date)
Hard-boiled eggs (in shell): 1 week
Hard-boiled eggs (peeled): 5 days (store in water in a ComSaf Glass Jar)
Raw egg whites or yolks: 2–4 days in a sealed ComSaf Airtight Container
Frozen whole eggs (beaten): up to 12 months

The Float Test: Is This Egg Still Good?

Place the egg in a bowl of cold water. Fresh eggs sink and lay flat. Older eggs stand upright. Eggs that float should be discarded — the air cell has expanded significantly, indicating spoilage.

How to Freeze Eggs

Never freeze eggs in the shell — they'll crack. Instead, crack and beat eggs together, then pour into an ice cube tray. Freeze, then transfer cubes to a SPLF Reusable Freezer Bag. Label with the number of eggs and date. Lasts up to 12 months.

Signs Eggs Have Gone Bad

Float in water (float test)
Sulfur or rotten smell when cracked
Pink, green, or iridescent egg white (bacterial contamination — discard immediately)
Black or green spots inside

Quick Tips Summary

✅ Store in the original carton on a main shelf — not the door
✅ Keep pointy end down for maximum freshness
✅ Store away from strong-smelling foods
✅ Use the float test to check freshness
❌ Don't store on the fridge door — temperature fluctuates too much
❌ Don't freeze eggs in the shell — they'll crack
