5. Potatoes
Potatoes often contain Clostridium botulinum, a form of bacteria that is often found in soil. The spores of bacteria are not harmful but they produce 4 neurotoxins that attack the central nervous system.
If you bake potatoes in a microwave, the heat does not spread evenly, resulting to hot and cold spots. Bacteria can survive within the cold spots and can increase in number and lead to botulism, a serious health condition which causes paralysis.
6. Frozen Meat
Freezing is the best way to store meat as it prevents the multiplication of bacteria within the meat. But, thawing meat in a microwave can be uneven, so it is best to thaw frozen meat using conventional methods. While the outer parts of the meat might seem to be perfectly thawed, the inner parts might remain frozen.
When you cook the meat immediately after, some portions will take longer time to cook and under-cooked meat is likely to contain bacteria, which will lead to food poisoning. Additionally, bone can shield meat from thorough heating in a microwave and so you must avoid this practice as far as possible.
7. Egg
Eggs often contain salmonella, a bacteria that can cause food poisoning. This bacteria is killed when exposed to high level temperatures that’s why it is important to make sure that eggs are cooked through and through. If you cook eggs in a microwave, it is likely to remain uncooked in spots and so the bacteria in these parts are not destroyed, which can cause food poisoning. Furthermore, trying to cook an egg within its shell can cause a build-up of high-pressured steam within the egg and it can explode violently when the shell is broken. This has been known to cause severe burns as well as vision-threatening corneal damage.
