Milk-borne salmonellosis accounts for approximately 48.0 % of all milk-borne outbreaks reported in different
industrialized countries1. Although in Rwanda limited information is available on food-borne disease, the prevalence
of Salmonella in milk and dairy products indicates a high probability of salmonellosis occurrence. In Rwanda, where
the co-existence of the formal and informal markets as well as in other developing countries was noticed, a recent
study conducted by Kamana2 revealed that 8.3% (n=96) of Gouda cheese and11.4 (n=96) of boiled milk were
contaminated by Salmonella at consumption level.
