Extended feed storage to reduce the risk of virus survival has not been tested experimentally. Five ingredients inoculated with porcine epidemic diarrhea virus, porcine reproductive and respiratory syndrome virus-174, and Senecavirus A were stored indoors at 20°C or outdoors in Minnesota winter conditions. After 30 days, outdoor samples contained infectious virus, while indoor samples did not.
