Steel cans sometimes are. Depends on the food. Tomatoes are usually in copper-coated cans(orange), pineapple in tin-coated cans(matte grey), but there are chrome coatings(yellow) white enamel, and plastic. Look at the inside of the can. Heating the can will reveal if it’s a metal coating or plastic.
That’s bad.
Are tin/steel cans (for food rather than drink) also tainted?
