Stop Washing These 5 Foods—You Might Be Doing More Harm Than Good

1. Raw Chicken

Various types of meat, such as beef and pork, are particularly frequently rinsed in water and cooked. However, the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Agriculture (USDA) recommend against washing raw chicken.

When washing raw chicken in the sink, running water or splashes can spread bacteria such as Campylobacter and Salmonella from the chicken’s surface to the sink, surrounding kitchen equipment, and other foods. This increases the risk of cross-contamination and foodborne illnesses.

Washing raw chicken with water can inadvertently spread bacteria to the surroundings. If the bacteria transfer to cooking utensils or other food surfaces, an action intended for hygiene can promote bacterial growth. A study conducted by the USDA in collaboration with North Carolina State University found that 60% of kitchen sinks and their surroundings became contaminated with bacteria after washing raw chicken.

Instead of washing raw meat, using a paper towel to remove blood and impurities is preferable. Even if bacteria are present on the surface of raw meat, cooking it thoroughly will kill the germs. If you must wash it, do so last among your food items. Wash vegetables, meats, fish, and raw chicken, ensuring that pre-washed items and cooking utensils are kept safe.

2. Eggs

When hens lay eggs, they form a protective coating called the bloom that prevents bacteria from entering. During distribution, handlers sanitize the eggs to ensure this coating remains intact.

However, washing eggs at home can damage this protective layer, allowing bacteria to enter the egg. Therefore, it is best to keep eggs refrigerated and gently wipe any soiled shells with a clean, dry cloth rather than wash them with water.

3. Fish

Similar to meat, washing fish under running water can lead to cross-contamination. It is advisable to cook fish directly without washing. However, freshly caught shellfish, such as clams, oysters, mussels, and scallops, should be cleaned to remove sand and dirt before cooking, making washing necessary.

4. Mushrooms

Mushrooms contain cancer-fighting compounds that dissolve easily in water. When exposed to water, mushrooms are more likely to lose both flavor and nutrition. You can cook mushrooms without washing them. However, using a damp cloth to wipe the contaminated areas is preferable. Be cautious not to soak dried shiitake mushrooms in water for too long.

5. Pasta

To enjoy pasta at its best, avoid rinsing it with water. Pasta contains starch, which helps the sauce adhere better. Rinsing pasta noodles removes the starch. Instead, cook the pasta in boiling water and gently rinse it with cold water to maintain its texture and flavor.
