Biological decontamination of FFRs using a domestic microwave oven is an attractive idea since it has the advantages of convenience and short treatment times. The decontamination method used here treats the microwave oven as a source of dry heat, similar to other studies. Elhafi et al. (2004) demonstrated that four avian viruses (infectious bronchitis virus, avian pneumovirus, Newcastle disease virus, and avian influenza virus) were inactivated on dried cotton swab samples using a domestic microwave oven for as little as 20 s. Rosaspina et al. (1994) demonstrated destruction of Mycobacterium bovis dried onto scalpel blades after 4 min of microwave exposure.
