Should You Wash Eggs Before Using Them?

Washing eggs before using them is a topic that sparks some debate. While commercial eggs in the United States are already washed before sale, many people wonder if they should wash them again at home. Washing eggs can remove visible dirt but could potentially introduce harmful bacteria if done incorrectly. However, washing farm-fresh eggs that have not been commercially cleaned might be necessary.

To Wash or Not to Wash: What’s the Deal?

You might have heard conflicting advice about washing eggs. On one hand, some people say washing eggs can help remove dirt and bacteria. On the other hand, experts claim that washing eggs could do more harm than good. So, what’s the truth?

Commercial Eggs: Already Cleaned

In the United States, commercial eggs are washed and sanitized before hitting the store shelves. This process removes dirt and bacteria from the eggshell. Given this, there’s generally no need to wash these eggs again at home. Moreover, washing commercial eggs can remove the protective coating, making it easier for bacteria to enter the egg.

According to the United States Department of Agriculture, it’s not necessary or recommended to wash commercially packaged eggs.

Should You Wash Eggs Before Using Them?

Farm-Fresh Eggs: A Different Story

If you get your eggs from a local farm, they might not undergo the same cleaning process as commercial eggs. In such cases, washing eggs could be beneficial. However, you should do this just before using them to maintain the natural protective layer as long as possible.

The European Approach

In Europe, commercial eggs are generally not washed. Research has linked this practice to a lower incidence of salmonella, possibly because the natural bloom remains intact. This indicates that not washing could actually be beneficial in some instances.

Risks of Washing at Home

When you wash eggs at home, you run the risk of introducing waterborne bacteria. The eggshell is porous, so any contaminated water can seep through and contaminate the egg inside. Therefore, it’s generally advised not to wash these eggs before use.

How to Wash Eggs Safely

If you decide to wash your eggs, you should know how to do it right. Incorrect washing can introduce bacteria rather than remove it.

Water Temperature Matters

Always use warm water to wash eggs. Cold water can cause the egg’s contents to contract, pulling bacteria into the egg through the porous shell.

Don’t Submerge

Never submerge eggs in water. Instead, run them under a faucet or use a damp cloth. Submerging can push bacteria through the porous shell.

Use Food-Safe Sanitizers

If you’re extra concerned about bacteria, you can use a food-safe sanitizer. Just make sure to rinse the eggs thoroughly afterward.

Research Insights

Research suggests that washing eggs can effectively remove bacteria if done correctly. However, it also states that improper washing can introduce new bacteria. Therefore, the key lies in the technique, not just the act of washing itself.

What About Egg Safety in Cooking?

Regardless of whether you wash your eggs, cooking them properly is crucial for safety. Always cook eggs until both the yolk and white are firm to kill any bacteria that might be present. Moreover, always store eggs in the refrigerator to minimize the risk of bacterial growth.

The Bottom Line

So, should you wash your eggs before using them? The simple answer is No. But it depends on where they come from and how concerned you are about potential bacteria. However, if you do decide to wash them, make sure you do it the right way to minimize risks.
