Objective. To detect the presence of specific antibodies against Hepatitis E virus (HEV) in pigs slaughtered in Antioquia, the department where the greatest amount of pork is produced and consumed in Colombia. Materials and methods. Between September 2011 and May 2012, blood samples from pigs were obtained in five slaughterhouses of Antioquia, four of them located in the Aburrá Valley subregion and other located in northern subregión. Serum were evaluated with a commercial ELISA kit for diagnosing HEV in humans but adapted to detect IgG and IgM antibodies in pigs. Results. A 100.0% seropositivity for IgG antibodies was found in 1000 samples evaluated, and 82.06% for IgM antibodies were found in 740 samples. Conclusions. These results indicate that pigs in slaughter age in Antioquia, and possibly in Colombia, have been exposed to HEV at some point in their production process and a high percentage of them can arrive to slaughterhouses with recent infection.
