A survey was carried out to determine the prevalence of Toxoplasma gondii
antibodies among cattle farmers and cattle in the Gombak District, Selangor. A total
of 79 human and 73 cattle serum samples were tested for Toxoplasma gondii
antibodies by the immunofluorescent technique (IFAT). Results of the survey showed
that anti-Toxoplasma gondii antibodies were found in 27.8% of the farmers, while in
cattle the positive rate was only 3.8%. The prevalence rate obtained in this study did
not differ much from the prevalence reported in previous studies. This suggests that
the same degree of risk to this infection exists in the community. In view of the
relatively low antibody prevalence in cattle, the risk of acquiring this infection from
consuming undercooked beef is realtively low. Further survey on larger sample sixe is
needed to validate the observation.
