I believe it is so important for people to observe labels, ask questions, etc. It is a disgrace that people would lie to costumers in this manner. Ultimately, it seems like the way to go is grow your own veggies!
Yes this is one of the reasons I am very choosy if I go to a farmers market. Many farmers use the same chemicals at their farms as the big producers do to have a good crop that they can sale at a local market. If you do not know the farmer and know how they actually farm then you may be better off to get your vegetables from your own garden or a store.
