Should You Wash Eggs Before Cooking? Here’s What Food Safety Experts Say

Eggs are a staple in many households because they are affordable, rich in protein, and easy to cook. From breakfast omelets to soups and fried rice, eggs appear in countless daily meals. However, many people still have the habit of washing eggs thoroughly before storing or cooking them, believing it makes them cleaner and safer.

But according to food safety experts, washing eggs the wrong way may actually increase the risk of bacterial contamination — especially from Salmonella, one of the most common causes of food poisoning.

Why Washing Eggs Can Be a Problem

Eggshells may look smooth, but they actually contain thousands of tiny pores. On the outside of the shell is a natural protective coating called the “cuticle” or “bloom,” which helps block bacteria from entering the egg.

When eggs are washed with water — especially cold water or by soaking them for too long — this protective layer can be damaged. Moisture left on the shell may also encourage bacterial growth. If bacteria such as Salmonella are present on the shell, they can potentially move through the pores and contaminate the inside of the egg.

So, Should You Wash Eggs?

Experts say that if eggs only have a little dust or dirt on the shell, it’s better not to wash them before refrigeration. Instead, gently wipe the shell with a dry paper towel or clean cloth. Eggs should only be rinsed right before cooking if absolutely necessary — and they should be cooked immediately afterward.

Interestingly, many supermarket eggs are already professionally cleaned and coated with a protective layer before being sold, meaning additional washing at home may not be needed.

How to Store Eggs Safely

To reduce the risk of contamination:

• Store raw eggs separately from cooked foods, fruits, and vegetables.
• Keep eggs refrigerated at around 0–4°C (32–39°F).
• Place eggs with the pointed side facing downward to help maintain freshness longer.
• Avoid leaving eggs at room temperature for extended periods, especially in hot and humid weather.

Cook Eggs Thoroughly

High temperatures can kill most harmful bacteria, including Salmonella. Experts recommend cooking eggs until both the yolk and the white are fully set. This is especially important for children, pregnant women, older adults, and people with weakened immune systems.

Dishes made with raw or undercooked eggs may carry a higher risk of contamination if the egg source is not reliable.

Healthy Ways to Eat Eggs

Although eggs are highly nutritious, experts recommend avoiding overly greasy egg dishes or pairing eggs too often with processed meats such as bacon and sausages, which can increase saturated fat and sodium intake. Healthier cooking methods include boiling, steaming, poaching, or lightly pan-frying with less oil.
