Potatoes

The good news is that you can certainly microwave raw potatoes without a problem. But I n that case, why is it on this list? The true problem, though, is reheating already-cooked potatoes. C. botulinum is found in potatoes. When you cook potatoes and don't store them immediately, you might risk the bacteria growing.

Potatoes are linked to a type of bacteria called botulinum, which can seriously harm your health. It can cause risky disease that attacks nerves and may cause breathing problems, muscle paralysis, and even death. Typically, the bacteria develop in spaces with low oxygen, like when a potato is wrapped with aluminum foil to bake it. So you should consume the food as quickly as possible because the bacteria that are cooked in aluminum foil are protected by the foil. This implies it's generally not a good idea to eat leftover potatoes. If you must, re-bake them without the foil so that the heat can kill the bacteria.
