Food vendors in night markets or food courts are favorite choices for tourists or city residents to spend their leisure time. The aim of this study was to investigate of counseling of food vendors of the tourist night markets and food courts to implement ＂food hygiene self-management＂ to comply with ＂good hygiene practices＂ guidelines. The range encompassed famous tourist night markets and food courts in four regions of Taiwan. Suitable districts were selected by on-site visits and enrolling the voluntary vendors as counseling subjects. The counseling program evaluation criteria involved five benchmarks: ＂employee health examinations＂, ＂environmental sanitation management＂, ＂appliances and equipment hygiene management＂, ＂the control of food materials＂ and ＂the control of preparation processes and food quality＂. Assessment tasks were performed by the inspectors of local health authorities and academic experts after on-site visits counseling and a sanitation workshop. There were 136 vendors in this study, and 105 passed the assessment in this project. After half of the counseling program, there were significantly improvements in five benchmarks of the food hygiene self-management (p＜0.05). The top five weaknesses of vendors in this investigation consisted of ＂cross-contamination issues＂, ＂inappropriate food storage control＂, ＂lack of employee's health examination＂, ＂poor environmental sanitation of the food stall＂, and ＂not wearing coveralls when they work＂. The results can provide the local health authorities and vendors ways to improve critical sanitation management.
