Washing fruits and vegetables with plain running tap water and a gentle scrub is the most effective and safest method for removing pesticides, according to medical toxicologists and food safety experts. This approach is recommended over trending social media methods involving baking soda, white vinegar, or commercial produce washes.
Concerns about pesticide consumption stem from their potential link to serious health issues. "Some pesticides can cause neurologic damage, while others are associated with chronic health conditions such as cancer," said Dr. Kelly Johnson-Arbor, a medical toxicology physician and medical director at the National Capital Poison Center. Other potential effects include disruption of reproductive or developmental processes, commonly referred to as endocrine disruption.
Despite these concerns, federal agencies like the Environmental Protection Agency suggest that the amount of pesticide exposure from consuming produce is typically very small and unlikely to pose a risk. However, for individuals who wish to minimize any potential exposure, experts offer clear guidance.
The U.S. Centers for Disease Control and Prevention and the Food and Drug Administration both endorse washing produce with running water. "Plain running tap water remains the simplest and safest method" for removing germs and pesticides, Johnson-Arbor stated.
Experts strongly advise against using soaps, detergents, or store-bought produce washes. "Because produce is porous, soaps and detergents can be absorbed even with thorough rinsing, and this can lead to illness," explained Emma Laing, director of dietetics at the University of Georgia. The FDA has not adequately tested the safety and effectiveness of these specialized washes.
Soaking produce in water is also discouraged. While it may help remove surface residue, it can increase the spread of germs and contamination through the soaking water, according to Johnson-Arbor. Additionally, caution is advised regarding washing produce in sinks, which can harbor more germs than commonly assumed.
For produce with rough surfaces, crevices, or leaves, more thorough cleaning methods are recommended. Gardener and author Chris Young suggests gently rinsing these items under cool running water. For leafy greens, separating and rinsing leaves individually is advised. A soft produce brush can be used to scrub sturdier items like melons or cauliflower to remove dirt and debris.
It is also important to wash produce with thick rinds, such as watermelons and cantaloupes. Even if the skin is not consumed, washing helps prevent dirt and bacteria from being transferred to the edible parts during peeling or cutting. This applies to fruits like mangoes and honeydew melons, which are peeled before eating.
Scrubbing the surface of fruits and vegetables, either by hand or with a clean produce brush, significantly aids in removing dirt, bacteria, and pesticide residues. It is crucial to keep any brushes used for produce clean to prevent cross-contamination.
For those seeking to avoid synthetic pesticides entirely, purchasing certified organic produce is the most effective option. While organic produce may still have a higher price point and varying availability, it is grown with only naturally occurring or plant-based pesticides, according to USDA guidelines. Even organic items should be rinsed and scrubbed to remove dirt and natural germs.
