The Bangkok Metropolitan Administration (BMA) yesterday urged hotels and shopping malls to clean their air-conditioning systems as a precaution after a recent random check found that several hotels had legionella bacteria, which could pose a risk of respiratory diseases.
BMA Health Office environmental sanitation division head Injira Niyomtoon explained that a random check on hotels, malls and cinema theatres had found some premises with dust, bacteria and fungi, but the situation wasn’t worrisome. However, a couple of were found to have legionella bacteria, which could stem from poor ventilation or sub-standard carpet maintenance.
The authorities have instructed them to clean the areas and qualify for the “Clean and Green” sign to boost customers’ confidence.
