The highly pathogenic avian influenza (HPAI) outbreak that devastated poultry producers during the winter and spring of 2015 was the worst animal disease in U.S. history. It affected more than 48.8 million birds and 21 States before the final detection on June 17. The incredible scope of this outbreak presented many challenges to Federal, state and industry resources and clearly identified areas where greater coordination, preparation and communication were needed. While response operations continue in the Midwest, APHIS and its partners have used the time since the last positive detection to plan for the return of the disease, using a hypothetical worst case scenario in an effort to prepare.
The Montana Department of Livestock (MDOL) is the lead HPAI response agency and encourages poultry producers to prepare for the disease. Prevention (biosecurity), surveillance (early diagnosis), an understanding of the response to a diagnosis such as depopulation, disposal, cleaning and disinfection are important factors for producers to understand.
