Dangers of Canned Foods

When I purchase canned foods, I always look for a peel off aluminum top. I do not like the old type cans that require can openers to open them. If a can opener does not have a strong magnet, tiny particles of metal may fall into the food. If swallowed, the slivers may stick into the throat; or, even go into the lungs and stick. I have experienced many times when large slivers of metal were deposited in the food. I had to throw the food away. Though the body may handle metal slivers, it is best to avoid any and all canned foods that do not have peel off tops.
