OBJECTIVES To evaluate the public health impact of milk contamination in Bamako, Mali. METHODS A case-control study assessed the risk-factors for food-borne toxi-infections with diarrhoea and vomiting as main clinical picture. A total of 131 schoolchildren between 5 and 20 years of age were interviewed by trained interviewers in schools in Bamako. A structured questionnaire was used to record health problems, food and particularly milk consumption habits and socio-economic indicators. RESULTS Final multivariate logistic regression analysis identified regular consumption of boiled milk [odds ratio(OR) = 4.38; 95 1.15-16.71], age between 5 and 10 years (OR vs. age group 11-15 years = 3.28; 95 household (OR = 7.65; 95 diarrhoea and vomiting. Other milk products and the socio-economic level of the household were not significantly associated with the outcome. Many people were unaware of the potential risks of milk consumption. CONCLUSIONS Milk products may be a risk factor for food-borne toxi-infections. Attention has to be paid to products considered safe, such as boiled or pasteurized milk. The low awareness of potential risks of many people may increase the risk of milk consumption. To achieve a sustainable increase in local milk production in Africa, milk quantity and production and transformation quality should be improved simultaneously.
