Evaluation of porcine cysticercosis was measured by tongue palpation and serum antibodies detected by Western blot, while that of human taeniosis was measured by coproantigen detection. Assessment was performed before intervention (n = 1,404 for humans and 194 for pigs), 6 months later (n = 792 for humans and 165 for pigs), and 42 months later in 1996 (n = 605 for humans and 334 for pigs).
