title: Inactivation of Avian Influenza Virus in Nonpelleted Chicken Feed.
abstract: Corn stored outside could become contaminated with avian influenza virus (AIV) from wild bird droppings. AIV-contaminated ingredients could pass into the poultry flocks in nonpelleted chicken feed. The efficacy of two disinfectants at inactivating AIV in chicken feed was evaluated. Both Termin-8 (a blend of formaldehyde, propionic acid, terpenes, and surfactant) and Finio (a blend of approved phytochemicals and carboxylic acids) effectively inactivated AIV in chicken feed. Because stability of infectious AIV in chicken feed is limited, we evaluated addition of protein (skim milk powder) to the virus suspension. Protein prolonged the stability of AIV in untreated feed to 24 hr at 24 C. However, both feed disinfectants were able to inactivate the virus in feed even when protected by skim milk powder.
