Thoroughly inspect all areas of the can for defects. One way to tell if a can is potentially dangerous is to push on the top and bottom of the can. If the top or bottom of the can moves in any way or makes a popping sound, the can’s seal has been broken and air has made its way inside.
Popped cans should be discarded or returned to the store or distributor where they were purchased. If the can does not make a noise or move, it is most likely safe for consumption despite any dents.
Check all seals and seams. Discard the can immediately if you notice any holes, sharp dents, punctures, bulges, leaks or seepage. Products in slightly dented cans are safe to consume as long as there are no leaks, and the product appears wholesome.
