A new study from the University of Southern California (USC) has some bad implications. Particularly for younger, non-smokers, those who ate lots of fruits, veggies, and whole grains seemed to have a higher risk of early‑onset lung cancer. It’s counterintuitive, and some experts think it may point to pesticides that we use in farming.Â
‍
This study doesn’t mean we shouldn’t be eating our 5-a-day (the health benefits of a diet rich in fruit and veg overwhelmingly outweigh any risks), but it does call into question how we grow, process, and wash our produce. In particular, leafy greens and berries are often at the top of the “dirty dozen” list of products that have the most pesticide residue on them when they get to our homes or restaurants.Â

Washing all produce thoroughly before consuming it is key. In most cases, rinsing and gently rubbing them under cold water is all that’s recommended. Specifically leafy produce is challenging and requires extra attention, proper training and patience when prepping. Some restaurants use a no-rinse chemical fruit and veggie wash, like EcoLab’s Victory Wash or Diversey’s Suma Eden. It is not a universal practice, though, in part because the FDA doesn’t recommend chemical washes — but only because they don’t test washes or cleaners for safety and effectiveness. EcoLab, however, states that their version, Victory Wash, kills 99.9% of the pathogens E. coli O157:H7, Listeria, and Salmonella enterica in wash water.Â
‍
Whether or not you use a commercial produce wash, one thing is very clear: don’t use bleach, soap, or any other chemical that isn’t specifically designed to wash veggies. Wash your fruits and veg immediately before use to prevent bacterial growth, and store prepped produce at proper cold holding temperatures. And rest assured - this news isn’t nearly enough to keep us away from our apple-a-day.Â
