The prevalence of brucellosis among abattoir workers in Saudi Arabia w
as determined through a randomised multi-stage sampling of 1200 abatto
ir workers. Diagnosis was made by both blood culture and standard tube
agglutination test. The overall prevalence of brucellosis was 4.0% am
ong abattoir workers. Infection was more common among butchers (8.9%),
veterinarians and veterinary assistants (5.4%), and administrative pe
rsonnel (1.1%). In order to reach optimum planning for a national bruc
ellosis control programme in Saudi Arabia, ministerial co-ordination s
hould be established with formulation of inter-governmental veterinary
agreements between the Saudi government and the relevant authorities
of animal exporting countries. A national survey on animal marketing i
s required.
