In my family Thanksgiving means cranberries, sweet potatoes, and green bean casserole. So I decided to check these foods out on WhatsOnMyFood.org. The results weren’t exactly appetizing. Here’s what the USDA found, after washing:
Green beans: 44 different pesticides with the most commonly detected being acephate, a highly neurotoxic organophosphate insecticide. One sample had 200 micrograms of it per 100 gram serving (slightly more than one cup). That may not sound like a lot, but it's twice the EPA's level of concern for children.
