Assessment of knowledge, attitudes and practices relating to brucellosis among cattle farmers, meat handlers and medical professionals in Namibia

Abstract

Background

Brucellosis is a re‐emerging zoonosis of significant socio‐economic, animal and public health importance. It is principally a foodborne or occupation‐associated infection of humans, whose effective control depends on maximum cooperation of high‐risk populations.

Objectives

The study assessed knowledge, attitudes and practices relating to brucellosis among cattle farmers (communal and commercial), meat handlers (abattoir and butchery workers) and medical professionals (nurses and doctors) in Namibia.

Methods

Between June 2019 and September 2020, self‐administered questionnaires and questionnaire interviews were carried out in cattle farmers ( n = 264), meat handlers ( n = 143) and medical professionals ( n = 124) in Namibia.

Results

Overall, 43.50% (231/531) of respondents were aware of brucellosis, with the highest awareness among medical professionals (73.39%, 91/124) and the least in meat handlers (13.99%, 20/143). Awareness of brucellosis was associated with tertiary education ( p < 0.001) and the medical profession ( p < 0.001). However, most medical professionals (98.39%, 122/124) did not consider brucellosis as a differential diagnosis in cases of persistent febrile illness. A proportion of communal (85.60%) and commercial (71.00%) farmers; abattoir workers (44.40%); butchers (53.50%); nurses (55.60%); and medical doctors (28.00%) consumed raw milk.

Conclusions

The study identified the purchase of animals of unknown health status; assisting cow delivery; handling of aborted fetuses with no protective wear; consumption of raw milk, homemade cheese, cattle testes and undercooked livers, as risk factors for Brucella infection in cattle and humans. Thus, intensified risk communication, including public health education, is recommended, in particular, among meat handlers and communal farmers, to promote awareness and discourage risky practices.

Abstract

This study assessed knowledge, attitudes and practices regarding brucellosis among cattle farmers, meat handlers and medical professionals. Respondents had a low level of awareness and knowledge of brucellosis, and showed attitudes that can expose them to infection.
