Your home kitchen isn’t subject to these same sky-high standards for safety and cleanliness.
“Washing them again [at home] 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 the greens might come in contact with during the washing process,” Cochran says.
A few years back, the Centers for Disease Control releaseda videothat outlined why you shouldn’t wash poultry in your sink: because potentially harmful bacteria from the chicken might splatter around your kitchen and contaminate other foods. Predictably, people went nuts, and many couldn’t imagine not washing their chicken before cooking it.
Trust that your pre-washed lettuce is ready to eat.
That bag of salad mix in your fridge has already undergone a three-step process to make sure there’s no bacteria or foreign objects. The three steps in triple-washing include:
If you buy unwashed greens, then youdohave to wash them—here’s how to do it.
“First, wash your hands with warm water and soap for at least 20 seconds before and after handling the leafy greens,” Cochran says. “Then use hot water and soap to clean all surfaces like sinks, countertops, bowls, salad spinners, colanders and strainers that will be used in washing the leafy greens.”
If you’re working with a head of lettuce or a bunch of greens, first remove the core or stems, so that you’re left with just the leaves. If you have pre-packaged, unwashed greens, then the leaves should already be separated.
“Separate and individually rinse the leaves under cold running tap water,” Cochran says. “For leaves that can’t easily be held under running water, place them in a bowl of cold water for a few minutes to loosen sand and dirt.” Transfer the greens to a strainer or colander to drain excess liquid, then dry them with a clean cloth or (preferably) paper towel.
Obviously, you shouldn’t use bleach or detergent to clean the greens, because they’re not meant to be consumed. “The FDA also advises against using commercial fruit and vegetable washes because they may leave residues,” Cochran says. “Plus their safety and effectiveness have not been thoroughly tested or standardized.” It’s even possible that they’re less effective for washing than water alone.
The bottom line
The safest way to eat leafy greens is to buy them pre-washed. Unless you follow strict food safety guidelines and regularly invite a health inspector into your home, your kitchen just isn’t as clean as a commercial facility. Best to leave the washing to the experts.
