Experts have warned that leaving dirty dishes soaking in water overnight can turn the kitchen sink into an ideal environment for the proliferation of dangerous bacteria linked to food poisoning and other illnesses.
Many people habitually leave their dirty dishes soaking or piled up in the kitchen sink after eating until morning, without realizing that this simple behavior may pose a health risk.
Microbiologists have confirmed that the warm, humid conditions provided by soaking dishes and cutlery in kitchen sinks contribute to the proliferation of harmful microbes.
Microbiologist Jason Titor said , "As a microbiologist, I see the kitchen sink as an ideal haven for microbes and their transmission."
He explained that studies have shown that the kitchen sink is where various types of unwanted bacteria accumulate, including fecal coliform bacteria, foodborne pathogens, and even skin bacteria.
Research conducted by Cardiff Metropolitan University , which included swabbing surfaces in the kitchens of 46 homes across Britain, showed that sinks contain more bacteria than any other area in the kitchen, according to the British newspaper, the Daily Mail.
Experts pointed out that this is partly due to the use of sinks in preparing raw food, as many people admitted to washing poultry and meat before cooking it, which helps spread bacteria in the kitchen.
Escherichia coli bacteria are among the most commonly found microbes in kitchen sinks. This bacteria, which can be fatal in some cases, is associated with fever, vomiting, and diarrhea, as well as an increased risk of colon cancer, especially in people under fifty.
Brian Labus, a public health expert at the University of Nevada, explained that leaving dirty dishes piled up next to the sink is dangerous.
He added that "bacteria multiply more clearly in warm, humid environments, which is exactly the case in the kitchen sink when soaking pots and pans. It is true that dry environments may prevent bacteria from growing, but this does not mean that they cannot survive or grow later, and leaving food scraps uncovered may attract insects that transfer bacteria to the food scraps.
To reduce the risk of food poisoning, experts recommend using a dishwasher, as it washes dishes at a high temperature, which helps kill harmful microbes.
The UK Food Standards Agency (FSA) also recommends avoiding washing raw meat, as this may leave bacteria on surrounding surfaces, utensils, and food.
These warnings came in light of food poisoning cases in Britain last year, which resulted in the death of two people and the hospitalization of more than 100 people, in addition to 300 other people becoming ill.
