The porcine cysticercosis seroprevalence was determined in rural villages of Tumbes, Peru. Samples from 97% (1872/1927) of pigs, older than 7 months of age, from 17 rural villages of Tumbes province, Peru, were analyzed by the Electroimmunotransfer test. Also, village of origin, age, and sex were assessed to determine whether there was association with regard to the presentation of the disease by the Chi square test and logistic regression analysis. Seroprevalence was 45 ± 2.3%. Villages with higher seroprevalences were La Capitana, Carretas, and Rica Playa (70 ± 7.8, 69 ± 12.3, and 64 ± 6.8% respectively). Seroprevalence in pigs older than 12 months of age was 49 ± 3.1%, while in pigs 8 to 12 months of age was 40 ± 3.3% (p<0.05). There was no statistical difference due to sex. The results show that porcine cysticercosis is a serious public health problem for the villages surveyed.
