Yes, ice can go bad. It is technically a food, and like most foods, over time ice can harbor everything from bacteria to viruses that can cause illness, according to the International Packaged Ice Association. Bacteria like salmonella and E. coli can live in ice, because freezing does not kill these contaminants. Ice that's left in the freezer for a long time can harbor odors, too. Keep fresh ice in your freezer, and turn off the ice maker when you don't need it (you'll save water and energy with the flip of a switch). And dispose of old ice outdoors, where it can melt and water plants.
