We are one of the only states in the nation with a growing cancer rate, and have higher levels of certain kinds of cancers than do similar areas of the country.Many have put the blame on Iowa’s fields, while others say that legal pesticides are safe for us and the environment.In this episode we go down the rabbit hole to understand—how do chemicals become products on our shelves?
