    For several years, the demand for pork has been on the rise in Nepal. To assess the importance of pork as a carrier of zoonotic agents, we performed a cross-sectional study in the Kathmandu Valley of Nepal, in which we serologically determined the infection status of slaughtered pigs with regard to three of the most important parasites transmitted through pork consumption: Trichinella spp., Taenia solium cysticerci, and Toxoplasma gondii. From 2007 to 2010, 742 pigs were sampled at slaughter, of which 0.1% (95% confidence interval [CI] 0.0-0.7%) were found positive for Trichinella infection, 13.8% (95% credibility interval [CrI] 0.8-28.5%) for T. solium cysticercosis, and 11.7% (95% CI 5.2-17.5%) for Toxoplasma infection. Further monitoring of the related animal and human disease burden and strengthening of food safety protocols throughout the pork production chain are strongly recommended.
