A microbiologist has advised changing tea towels daily to mitigate the risk of spreading dangerous bacteria in the kitchen. Dr. Primrose Freestone from the University of Leicester stated that tea towels can rapidly become contaminated with germs from hands, food, and kitchen surfaces, potentially leading to illness.

These bacteria, including E. coli and Salmonella, thrive in the damp, nutrient-rich fibers of tea towels, especially in warm kitchen environments. When used to dry dishes or wipe spills, these towels can transfer bacteria to clean surfaces and utensils. Dr. Freestone noted that bacteria can multiply significantly in tea towels, posing a risk of food poisoning.

Research has indicated that bacteria can be present in up to 90% of used tea towels, particularly after contact with raw foods like chicken. Studies have shown that bacteria levels can be reduced by as much as 1,000 times if a tea towel is hung to dry properly for 24 hours between uses, compared to being left crumpled.

While some individuals opt to change tea towels only when they appear dirty or smell unpleasant, experts emphasize the importance of a daily change for hygiene. For those seeking to sanitize used tea towels, washing them and then using boiling water, a diluted bleach solution, or ironing them on a hot setting are recommended methods.

General kitchen hygiene practices, such as maintaining a clean workspace, avoiding cross-contamination between raw and cooked foods, using a food thermometer, storing food properly, and not relying solely on expiration dates, are also crucial in preventing foodborne illnesses.
