ABSTRACT
Objective To study food-borne disease related behavior of the floating population in Hangzhou city. Methods A questionnaire on food-borne disease related behaviors was formulated based on Delphi method. A family-based retrospective investigation was conducted by unified trained investigators to analyze the frequency of food-borne disease related behaviors of family food providers during the past month in several floating-population centers of Hangzhou city. The investigation was conducted among 150 adults of every survey spot quarterly during a one-year period. Data were analyzed using Mann-Whitney U test. Results According to all 1 781 valid recovery questionnaires, 82.42%subjects had a family income less than 50 000 yuan per year and 87.42%of them had junior-middle-school or lower levels of education. The proportions of subjects who always cleaned kitchen tools, covered the garbage can and kept house out of flies, roaches and mice were 42.50%, 55.87% and 61.09%, respectively. The proportions of subjects who always purchased intact packaged food and food under warranty were 39.70%and 52.33%, respectively. The proportions of subjects who always used tapped water, cleaned hands before food processing, cooked eggsand other foods till well-done were 66.03%, 51.94%, 53.62%, 35.99% and 32.62%, respectively. The proportions of subjects who always stored food in containers with cover and for no more than 3 days in freezer were 20.89%and 30.88%, respectively. The frequencies of food-borne disease related behaviors mentioned above were significantly higher among migrants who originated from urban areas, received education above junior-middle-school and had a family income no less than 50 000 yuan/y than the others (P<0.05). Conclusion In order to correct the risky behaviors during food consuming, processing and storage, targeted intervention is necessary among family food providers of floating population families.
