Absolutely! Although we don’t use chemicals (any more than absolutely necessary, and it hasn’t been necessary yet this year), our neighbors upwind do. In addition, our produce grows out there in the midst of nature where lots of critters and their body functions have access to it. While we will rinse off the bulk of dirt and so forth, there will be some amount of dirt and even some creepy crawlies from time to time. So please do at least rinse your produce unless you like grit and free protein!
