Avian influenza (AI) virus can survive outside a host for long periods depending on temperature and humidity of the environment.
The virus can live for up to one month inside a poultry house at 40 ºF.
It is important to undergo proper cleaning, decontamination, and disposal of litter, manure, and other contaminated products as the virus can linger on surfaces and in water.
AI is inactivated when heated to 158ºF for 1 hour or by exposure to disinfectants or extreme pH levels.
