Abstract
BackgroundBrucellosis is one of the major zoonoses globally with great veterinary and public health importance, particularly in developing countries where people are having frequent contact with livestock and animal products. This cross sectional study was carried out from November 2013 to May 2014 to determine the seroprevalence and assess the potential risk factors of brucellosis in abattoir workers of five export abattoirs at Debre Ziet and Modjo, Central Ethiopia.MethodsSerology and structured questionnaire were the methods used. In this study, 156 abattoir workers participated in the questionnaire survey and among them, 149 agreed for blood sample collection. Rose Bengal Plate Test and Complement Fixation Test were conducted using sera samples at serology laboratory of the National Animal Health Diagnostic and Investigation Center. Data collection sheets were used to gather information on possible risk factors believed to influence the spread of Brucella infection in abattoir workers such as sex, age, marital status, duration on job, types of work, educational level, etc. and further information obtained include knowledge of brucellosis and other zoonotic diseases infection, symptoms of the disease, milk and meat consumption habits and work related risk factors. Chi-square and Fisher’s exact tests were used for data analysis.ResultsThe overall seroprevalence of brucellosis in abattoir workers was found to be 4.7 and 1.3% using Rose Bengal plate test and Compliment fixation test, respectively. Based on the questionnaire survey, 66 (44.2%) and 85 (53.21%) of abattoir workers were aware of brucellosis and other zoonotic diseases, and 29 (18.6%) and 21 (13.5%) were using gloves and cover their mouth while slaughtering, respectively.ConclusionBrucellosis in abattoir workers could be prevented by using protective closing and measures. Concerned body should educate occupationally exposed groups and the general public regarding e prevention and control of brucellosis and other zoonotic diseases.

This study was aimed at estimating the seroprevalence of brucellosis in abattoir workers and assesses the factors predisposing abattoir workers to brucellosis in selected export abattoirs at Debre Zeit and Modjo, Central Ethiopia
Study areas There are seven functional export abattoirs found in Ethiopia, and five of them are located in the cities of Debre Zeit and Modjo, Central Ethiopia
Summary
Brucellosis is one of the major zoonoses globally with great veterinary and public health importance, in developing countries where people are having frequent contact with livestock and animal products. This cross sectional study was carried out from November 2013 to May 2014 to determine the seroprevalence and assess the potential risk factors of brucellosis in abattoir workers of five export abattoirs at Debre Ziet and Modjo, Central Ethiopia. Most of them are zoonotic diseases and have great veterinary and public health impact, in developing countries where people are having daily frequent contact with.
