A total of 438 sera were collected from dairy goats on 10 farms located around Aregue Village, Lara State, Venezuela and evaluated for Toxoplasma gondii antibodies using the indirect hemagglutination assay. Antibodies to T. gondii were found in 26 of 386 > or =4-yr-old does from 8 of 10 farms; antibody titers were 1:64 (10 does), 1: 256 (3 does), 1:512 (5 does), 1:1,024 (1 doe), and 1:4,096 (7 does). Antibodies were not found in 52 <12-mo-old goats.
