Your farm was definitely doing things right. But this issue is more to do with GMO and glyphosate. It's on wheat, alfalfa, soybeans, etc, which are bundled up for feed. I shortened the explanation to just say hay, because many of those talking about it do the same, but it's on a ton of food, that we ourselves eat as well. Guess it's more reason to ensure things say non-GMO and wash them anyway just in case.
