Why Washing Again Can Be Risky
Commercial food processing facilities maintain stricter standards than your kitchen. No matter how clean you keep your counters and sink, your home environment simply can’t match the controlled conditions of a professional food processing plant.
“Washing them again can actually increase the risk for leafy greens to pick up bacteria from your sink, countertops, cutting boards, knives, colanders, salad spinners, bowls or other items or surfaces in your kitchen,” food safety experts warn. These bacteria might include harmful pathogens from raw meat or other foods you previously prepared in the same area.
Think about it. Your kitchen sink is one of the most bacteria-rich zones in your home. When you rinse pre-washed lettuce there, you’re potentially introducing those greens to more contaminants than they had in the first place.
