No Transmission of Hepatitis E Virus in Pigs Fed Diets Containing Commercial Spray-Dried Porcine Plasma
Spray-dried porcine plasma (SDPP) is an ingredient commonly used in feed for pigs around the world. Even though processing conditions used to produce SDPP should be adequate to inactivate Hepatitis E virus (HEV), it was of interest to analyze commercial SDPP samples for presence of genome and antibodies (AB) against HEV and to retrospectively analyze serum samples collected from pigs used in past experiments that had been fed diets containing SDPP to detect potential transmission of HEV as determined by seroconversion, writes Joan Pujols et al, Centre de Recerca en Sanitat Animal (CReSA), Barcelona, Spain.
