The 2014-15 highly pathogenic avian influenza outbreak significantly impacted turkey and egg producers

The 2014-15 highly pathogenic avian influenza (HPAI) outbreak was the largest poultry health disaster in U.S. history. More than 50 million birds were lost to the disease itself or to depopulation, overshadowing bird losses during any previous U.S. outbreak. HPAI resulted in lower commodity production when supplies had previously been growing. USDA’s November 2014 forecasts for 2015 anticipated a 3-percent annual increase in both broiler and turkey production and a 2-percent increase in egg production. These projections, however, preceded the outbreak, which lowered egg and turkey production substantially during and afterward. In contrast, HPAI did not affect broiler production, with production growth continuing through 2015 and aligning with prior forecasts. Egg production declined for about 9 months, with the sharpest reduction occurring from May to December 2015, as production remained 10 percent below 2014 levels. The impact of HPAI on turkey production was initially similar to its impact on egg production, but it rebounded faster. While monthly production for June-July 2015 averaged 10 percent below the prior year, monthly production in August-December 2015 averaged only 5 percent lower. This chart appears in the ERS report Impacts of the 2014-2015 Highly Pathogenic Avian Influenza Outbreak on the U.S. Poultry Sector, released in December 2017.
