The study assessed milk producers’ awareness of milk-borne
zoonoses and prevalence and risk factors of brucellosis in
selected smallholder and commercial dairy farms of
Zimbabwe. A total of 119 dairy producers were interviewed;
21 (17.6%) commercial dairy and 98 (82.4%) smallholder dairy
farmers. Most respondents were males (74.8%) and the majority
(71.4%) of the respondents had undergone formal education.
Milk producers awareness of milk-borne zoonoses was low;
only 41.5% were aware with a significantly (P<0.05) higher
percentage of commercial dairy farmers (65.0%) being aware
compared to smallholder dairy farmers (36.7%). The prevalence
of antibodies to Brucella spp. in raw milk was low. Logistic
regression model identified dairy sectors (OR 3.1; P<0.04) and
vaccination status (OR 0.4; P<0.04) to be independently
associated with herd abortions status. Training milk producers
on milk-borne zoonoses, dairy hygiene and milk quality would
help to improve milking quality and reduce transmission of
zoonoses to public.
