Conference Abstract
European Federation of Animal Science (EAAP) 2015

Adequate processing of potentially contaminated raw material before use as feedstuff is a crucial aspect in the prevention of feed-borne transmission of porcine epidemic diarrhea virus (PEDV). Spray-drying of plasma and storage at dried conditions were demonstrated to inactivate 4.2 log10 PEDV/ml and up to 2.8 log10 PEDV/g, respectively. We examined the extent of PEDV inactivation by heat-alkalinity-time (HAT) pasteurization, an additional safety step in the production of spray-dried porcine plasma (SDPP).
