Foods that should not be reheated in a microwave oven.

For busy people, reheating food in a microwave is the most convenient and quickest way to have a hot meal. Therefore, this method is favored by many housewives. However, many people don't know that there are certain foods that shouldn't be reheated in a microwave because this method poses health risks.

Which foods should not be reheated in a microwave?

You can heat many foods in a microwave, but you shouldn't use it for the following foods.

Chicken

Not all chicken will cause food poisoning when reheated, however, it needs to be reheated properly.

Chicken and other poultry are very susceptible to salmonella contamination. Reheating leftover chicken in a microwave is problematic because the heat waves cannot penetrate the entire meat from the inside out. If chicken contaminated with salmonella is not heated thoroughly, the bacteria will survive, leading to food poisoning.

Another reason chicken is among the foods that shouldn't be reheated in a microwave is its higher protein density compared to red meat. When reheated, the protein breaks down to varying degrees and can cause stomach upset.

To ensure the safety of reheated chicken, you must make sure it is heated to a temperature above 73 degrees Celsius (165 degrees Fahrenheit) to kill harmful bacteria.

Dishes made with mushrooms

Reheating mushroom dishes to eat is a big mistake and can cause stomach aches and food poisoning.

Mushrooms are well-known for containing more nutrients than other vegetables. However, they should be eaten immediately after preparation. Mushroom dishes should not be reheated because when heated, the proteins and nutrients in mushrooms can denature and become toxic to the stomach.

Mother milk

Nowadays, due to busy work schedules and lack of time for direct breastfeeding, many mothers store breast milk in the refrigerator, and then those at home warm it up for the baby to eat. This wouldn't be harmful if they didn't heat the milk in the microwave – a method that easily produces E-coli bacteria (which cause diarrhea), negatively affecting the child's digestive system. Furthermore, carcinogenic substances can also be formed when plastic bottles containing breast milk are heated.

That's why breast milk is on the list of foods that shouldn't be heated in a microwave. If you need to warm breast milk, nutrition experts recommend using a double boiler or a dedicated breast milk warmer.

Egg

Eggs are high in calcium and rich in nutrients and vitamins, but when reheated, especially in a microwave, harmful substances can appear in the egg yolk.

Another reason why eggs are one of the foods that shouldn't be reheated in a microwave is that they are very prone to exploding.

Beetroot and radish

Radishes and beets are very nutritious, among the healthiest vegetables, and are chosen as ingredients in many stews and soups. However, they are foods that should not be reheated in a microwave. If you want to reheat soups or stews, be sure to remove all the radishes and beets, as the high amount of nitrates in these two vegetables can turn into toxic nitrites when exposed to heat a second time.
