I'm not sure if this is sarcasm... but if you actually trust/believe that farmers don't cheat during facility inspections, I don't know what to tell you. Every USDA organic farm I've ever had an inside track on is guilty, and that's quite a few. There is no random testing of domestic crops, only imports.[1] Domestic producers are subject to compliance, but the process is scheduled, typically sampling happens onsite, and the FDA makes announcements about crops it plans to investigate.[2]
My understanding from talking with experts is that imported produce in particular is subject to significantly greater oversight than domestic produce.
