It’s important to wash conventionally grown fruits and vegetables to help remove pesticide residue. So does that mean if you buy organic, you don’t have to wash your produce? No! And yet many people make the mistake of biting right into organically grown veggies and fruits without washing them first. 

Here’s why that thinking is backwards: Ingesting trace amounts of pesticides now and then probably won’t hurt you (though you should still try to avoid it.). But without proper washing of produce, you run the risk of ingesting a foodborne pathogen, which could be potentially life-threatening.

Foodborne pathogens can be on conventional or organic produce. For example, E. coli bacteria could get onto fruits and vegetables from manure in the soil they were grown in, or from the hands of pickers in the fields or fellow customers in the store.

The CDC estimates 3,000 Americans die from foodborne illnesses every year, including deadly outbreaks in recent years linked to produce like peppers and spinach. But the good news is you can reduce your risk. So whether you buy conventional or organic produce, here are the dos and don’ts for washing it properly.

Do:

Wash under running water: Researchers recommend using water over commercial products and home washing brews. Running water is even better because the action of the water dislodges residues and carries them off of the produce. Bunched fruit like grapes can be placed in a colander and then rinsed with running water. You can increase the friction by rubbing the produce with your (clean) hands.

Scrub with a brush: According to Barbara Rowe of the Utah State University Agricultural Extension service, it’s a good idea to use a vegetable brush on root vegetables, melons, cucumbers and citrus fruit because even though we don’t typically eat their skins, when you slice through the skin into the pulp of the produce, you can transfer bacteria to the inside.

Peel fruits and vegetables: The EPA suggests peeling fruits and vegetables, when possible, for an added layer of protection against pesticide residue and foodborne pathogens. 

Trim outer leaves. The FDA says it’s a good idea to trim off the outer leaves of things like lettuce, cabbage and celery, again to remove the outer layer that can contain more germs and residue.

Dry produce: The FDA says one last step is to pat produce dry with a clean towel or a paper towel, which provides one last opportunity for bacteria and pesticide residues to come off.
