How to Wash Fresh Eggs: Safe Practices & Steps for Clean, Infection-Free Eggs
Washing fresh eggs might seem like a simple task, but it’s an important step to ensure food safety and remove dirt, debris, and potential contaminants like salmonella. Contrary to popular belief, rinsing eggs before storage is generally discouraged in many countries—including the U.S.—due to the protective cuticle on fresh eggs. However, knowing how to properly clean and handle eggs safely is essential for home cooks, bakers, and farmers alike.
This article guides you through best practices for washing fresh eggs safely, explaining why proper hygiene matters and how to maintain the egg’s natural protection while keeping your food safe.
Understanding the Context
Why Washing Fresh Eggs Requires Care
Fresh eggs come covered with a natural protective layer called the egg cuticle or bloom, which prevents bacteria from penetrating the shell. Washing eggs removes this layer, exposing them to microbial contamination and increasing the risk of spoilage and foodborne illness.
That said, eggs may need cleaning due to dirt, manure, or other residues from the farm or market. The key is to wash them correctly and minimally, preserving their natural defenses.
Key Insights
When Should You Wash Fresh Eggs?
- After purchasing eggs from a farm or market where dust, dirt, or manure are present.
- If you prefer a visibly cleaner egg before use, especially for cracking or preparing dishes requiring pristine cleanliness.
Note: In many countries, including the U.S., FDA guidelines recommend not washing eggs before storage due to the risk of reducing the cuticle. If you do wash, ensure thorough drying immediately.

Step-by-Step Guide to Safely Washing Fresh Eggs
1. Start with Clean Hands and Work Area
Wash your hands with soap and warm water. Clean your counter or washing surface to prevent cross-contamination with bacteria like E. coli or salmonella.
2. Rinse Gently with Cold Water
Hold each egg under a cold running water stream—not so forcefully that it splashes water inside. This light rinse removes loose dirt without removing the cuticle. Avoid soaking eggs, as water can seep through tiny pores, accelerating spoilage.
3. Inspect Each Egg After Washing
Check for cracks, shell damage, or debris. Discard compromised eggs to prevent contamination.
4. Avoid Soaking or Aggressive Scrubbing
Never soak eggs or scrub with harsh detergents, detergents with bleach, or abrasive cleaners—these strip the protective cuticle and invite bacteria.
5. Dry Immediately
Use a clean, soft towel or paper towel to dry eggs thoroughly. Moisture encourages bacterial growth; drying helps preserve freshness and texture.
6. Store Properly
Keep eggs in their original carton or a breathable grid-style egg holder on a refrigerator shelf (not the door), ideally at 40°F (4°C) or below.
What If You Don’t Wash Your Eggs?
As mentioned, many experts recommend leaving eggs unwashed in permanent refrigeration with their cuticle intact. The cuticle acts as a natural barrier against pathogens and helps maintain moisture. Simply store clean, dry fresh eggs in a cool environment, and you’ll extend shelf life while minimizing risk.
