It is common to assume that the washroom is the most contaminated area in an office. However, a new study says that instead, it is the beloved office break room.A new research underscores the dangers lurking around inside the shared microwave. As per researchers, By 2 pm, food debris from breakfast and lunch has built up inside the microwave, creating an invisible layer of contamination. At this point, the warmth and moisture make it a breeding ground for bacteria, meaning anyone reheating their meal is at a higher risk of foodborne illness. As a precautionary measure, they have asked people to reheat their food in the first half, if they do not wish to get sick.Bacteria In Microwave Akin To Human SkinThe study, published in Frontiers, stated that the microwave oven bacterial population was dominated by Proteobacteria, Firmicutes, Actinobacteria, and Bacteroidetes, similar to the bacterial composition of human skin. Comparison with other environments revealed that the bacterial composition of domestic microwaves was similar to that of kitchen surfaces, whereas laboratory microwaves had a higher abundance of taxa known for their ability to withstand microwave radiation, high temperatures and desiccation. These results suggest that different selective pressures, such as human contact, nutrient availability and radiation levels, may explain the differences observed between domestic and laboratory microwaves. Overall, this study provides valuable insights into microwave oven bacterial communities and their potential biotechnological applications."Usually the break room is a germ transfer point in the workplace, people eat lunches there. Think of it as an unregulated restaurant. There are certain studies that show that microwaves in such shared break rooms contain bacteria which is commonly found on human skin like Staphylococcus. Other harmful bacteria found there are salmonella and E. coli," the researchers said.ALSO READ: How Safe Is It To Use Microwave For Reheating Food?How To Avoid Food Contamination?Avoid reheating food in later hours. If you can eat earlier in the day, do so. Otherwise, just grab a snack or something that doesn't need to be heated.Cover your food with a microwave-safe lid or paper towel. It can reduce the spread of food splatters. Make sure you use microwave-safe containers.Stir your food midway through to avoid cold spots where bacteria can thrive. If the microwave doesn’t have a rotating turntable, pause periodically to rotate the container manually.Your food should reach an internal temperature of at least 165°F (74°C), which is the temperature recommended by the USDA to kill most harmful bacteria.Besides, reheating food itself is not advised by experts. A study published in Food Science Nutrition 2024 stated that frequent reheating of food and its time significantly reduces the protein, mineral content, and oil quality of cow meat in general.ALSO READ: The Compelling Reason You Should Never Microwave PlasticMeanwhile, there is an ongoing debate on whether reheating food in the microwave increases or decreases nutrients. Certain research suggests that microwaving may cause nutritional loss, particularly in vegetables. For example, studies have shown that microwaving broccoli with water diminishes its flavonoid content, which are anti-inflammatory compounds. However, experts note that cooking methods and duration have a significant influence on nutrient retention. On the other hand, several studies indicate that microwaving preserves more nutrients than traditional cooking methods. Regardless, if you want to reheat your food in shared microwaves, be sure to do it before 2 pm!
