More than 80% of hand dryers installed in rest area restrooms in Gyeonggi Province were found to contain general bacteria and other microorganisms.
The Gyeonggi-do Institute of Health and Environment announced on June 23 that it had conducted a microbial contamination survey on 105 hand dryers installed at 25 highway rest areas in the province from March to May. As a result, pathogenic microorganisms were detected in 1 unit (0.9%), and general bacteria were detected in 85 units (80.9%).
The hygiene inspection of public restrooms at highway rest areas was carried out following a recommendation from the Health and Welfare Committee of the Gyeonggi Provincial Council during an administrative audit last year.

According to the survey, among pathogenic microorganisms, Escherichia coli, Salmonella, norovirus, and COVID-19 virus were not detected; however, Staphylococcus aureus was found in one unit. The level of general bacteria was up to 1,200 CFU (meaning there are 1,200 microorganisms capable of forming colonies in the sample) per unit, which is lower than the food standard for snacks (10,000 CFU).
The hand dryer in which Staphylococcus aureus was detected was immediately reported to Korea Expressway Corporation, which then replaced the filter and cleaned the interior. Upon retesting, no microorganisms were detected.
Kwon Boyeon, Director of the Gyeonggi-do Institute of Health and Environment, stated, "The hygiene management of hand dryers in public facilities is directly linked to the health of residents," adding, "We will strive to create a safe public environment by strengthening regular filter replacement and internal and external maintenance of these devices."
