The survival of selected viruses in fermented edible waste material was studied to determine the feasibility of using this material as a livestock feed ingredient. Pseudorabies, Newcastle disease, infectious canine hepatitis, avian infectious bronchitis, measles and vesicular stomatitis viruses and a porcine picornavirus were inoculated into a mixture of ground food waste (collected from a school lunch program) containing Lactobacillus acidophilus. Mixtures were incubated at 5, 10, 20 and 30.degree. C for 96 h. Temperature, pH and redox potential were monitored. Samples for virus isolation were obtained daily. Newcastle disease virus and infectious canine hepatitis virus survived the entire test period. The porcine picornavirus was inactivated at 30.degree. C after 72 h, but survived for the entire test period at the other temperatures. Pseudorabies virus was inactivated at 20 and 30.degree. C within 24 h, but survived for 48 h at 10.degree. C and 96 h at 5.degree. C. Avian infectious bronchitis virus was inactivated at 20 and 30.degree. C within 24 h, but survived 72 h at 5 and 10.degree. C. Measles and vesicular stomatitis viruses were rapidly inactivated at all 4 temperatures.
