We fear the E. coli, salmonella and listeria, but unfortunately, these bacteria live comfortably in many of our refrigerators. The reason is not cleaned well. A group of researchers took samples from the shelves and drawers for vegetables 30 home refrigerators and found an average of 7,850 bacteria in every square inch , as published by Marie Claire . This means that the average refrigerator has 750 times more bacteria than the level considered safe. "The purpose of a refrigerator is to keep food safe and minimize the chances of mold and bacteria grow, so is concern over the results of the investigation" said Paul McDonnell, the company Microban Europe, who led the study. "The operation of the refrigerators is especially important in hot climates. When bacteria get a balance and not done a good cleaning, they tend to multiply" , McDonnell said.
The researcher said that some owners of refrigerators emptied regularly to clean their refrigerators, but that others do as well, leading to a dangerous amount of bacteria residing with their food. According to another study conducted by Center for Disease Control, only 34% of people who took a questionnaire on the proper handling of food got a good grade. One of the most important points to keep bacteria at bay is to set the refrigerator temperature below 41 degrees.
