I have recently learned and had confirmed from food processors like Del-Monte and Progressive Foods, that all the canned food items we consume, the can itself is lined with plastic to protect the food from the reactions of the food to the metal. The Plastic itself unfornately leeches BPA a know cuase of infertility, and even cancer along with a host of other disorders. When I asked Progressive ( we like alot the various soups they make), they stated that the FDA has a standard count for BPA in food at 600PPB ALLOWED, and that they generate 60 - 90PPB well below the standard. I at that point stated that in all food items insect parts and rat hair are allowed up to a certian point. From manufacturing perspective, is fine but if your the one eating the half a cockroach or fishing the rat hair from your mouth, suspect those standards you would view as being too low. All plastics marked with the number 7 or unmarked at all are BPA contact chemical containers. just a bit of information.
