Survivability of H5N1 avian influenza virus in homemade yogurt, cheese and whey

Abstract

Influenza virus is typically associated with respiratory infections, but H5N1 in US dairy cows raises public health concerns about milk by-products. We show that simple home recipes can inactivate H5N1 in cheese, yogurt, and whey. While viral RNA was present, no viable virus was found, ensuring food safety.
