A study was conducted to determine risk factors associated with brucellosis infection in an outbreak in Chouf district of Lebanon during summer 2009. Cases of brucellosis reported to the Ministry of Public Health were identified, and for each case 2 controls were matched by sex, age and residence. Sociodemographic data, exposure to animals and animal products, knowledge about brucellosis, symptoms and history of past brucellosis infections were collected. Consumption of raw cheese was a significant risk factor for contracting brucellosis (matched OR = 29.5), whereas wearing gloves when in contact with animals and animal products and self-preparing dairy products were protective factors (OR = 0.08 and 0.13 respectively). Low and inaccurate knowledge about brucellosis was prevalent among subjects, with a common misconception about human-human transmission. Ensuring animal vaccination, educating people on correct ways of milk pasteurization and handling meat products, and elevating food safety monitoring threshold are key elements in controlling brucellosis.
