Commercial processing methods routinely used for the cooking of ground beef patties in the United States were examined for their virucidal activity against foot-and-mouth disease virus. Thermal processing of the patties in the broiler followed by 20 min oven cooking with an exit temperature of 99.7°C inactivated more than 4.0 log10 PFU of foot-and-mouth disease virus. The electronically controlled process was not only virucidal but produced a consumer-acceptable product.
