Abstract: Objective To understand the sanitary condition of accommodation in a certaincity of Guangdong province,to master the major health hazard factors,in order to provide scientific basis for strengthening sanitation management of accommodation. Method In 2021,6 accommodation in each of the 3 levels were randomly selected in a city jurisdiction,two rounds of monitoring in summer and winter,total of 36 accommodation were monitored for health hazards such as indoor air quality,public appliances and cooling water of cooling tower. Result The qualified rates of indoor air quality testing indicators were between 13.39% and 100.00%,and the qualified rate of temperature was the lowest（13.39%）,followed by relative humidity（38.39%） and noise（85.71%）. There were statistically significant differences in the qualified rate of temperature and relative humidity between different seasons（both P<0.01）. There was a significant difference in the qualified rate of noise between hotels under three stars and express hotels（P<0.05）. Among the public appliances,the qualified rate of pH value of towels and the total number of colonies of towels was 71.07% and 98.67%,and other project indicators were qualified. There were statistically significant differences in the qualified rate of pH value of towels in different seasons,star hotels and express hotels（both P<0.05）. The detection rate of legionella pneumophila in cooling water of cooling tower was 60.00%. Conclusion The qualification rate of most monitoring indicators for indoor air and public goods in accommodation facilities in a certain city in Guangdong Province is high,but the qualified rates of temperature,relative humidity,noise and pH value of towels are low,and the detection rate of legionella pneumophila in cooling water is high. There are potential health hazards,and relevant departments should strengthen health supervision and management.
