Study of water quality of sylhet city and its restaurants: health associated risk assessment

0
Sylhet is a developing city and a very attractive place for tourism. The city is very rich in natural resources and also attracts tourists and business entrepreneurs. Thus, it is imperative that the city maintains a health friendly environment, clean water and food. Since unclean water and food, poor sanitary and hygiene facilities in restaurants of the city remain a potential source of diseases and risk to human health, the present investigation aimed at studying water and food quality as well as sanitary conditions at selected restaurants of Sylhet city, along with determination of water quality of the major sources of water supply to the city Surma River and tube wells (ground water). According to Sylhet City Corporation, the city has 331 registered/licensed restaurants, however, many unregistered restaurants also exist. According to a survey by Ahmed and Rahman (2000), only 15% restaurants maintain sanitary facilities, whereas unhygienic conditions that are unsafe for public health prevail in 85% of the restaurants. Although A Bangladesh Standard code of Hygiene also exists (BDS, 1975), most restaurants and similar establishments have failed to conform to the code. An assessment of water and food quality in restaurants of Sylhet city has hardly been done, barring the study by Das and Rahman (2005). In this paper, food contamination by pesticides and associated health risks due to pesticide residue in food has been analyzed.
