The Iowa Department of Agriculture and USDA announced that all of the 72 commercial poultry farms that had a confirmed case of Highly Pathogenic Avian Influenza (HPAI) have had the quarantines on their facilities lifted and they are eligible to restock birds.
All sites have completed the cleaning and disinfection process and had negative environmental tests. They also had to undergo a 21 day fallow period following disinfection before the quarantine could be lifted.
Five backyard operations remain under quarantine. Backyard facilities must undergo a 180 day fallow period following depopulation before the quarantines can be lifted and birds brought back to the farm.
Now that fall migration of wild waterfowl is underway, bird owners are again reminded to exercise biosecurity to prevent the return of the disease. USDA Animal and Plant Health Inspection Service (APHIS) issued a report last month on its planning and preparation for a potential recurrence of the disease. APHIS’ fall plan focuses on four major areas: preventing or reducing future outbreaks; enhanced preparedness; improved and streamlined response capabilities; and preparing for the potential use of AI vaccines.
APHIS’ fall planning report not only discusses planning and preparedness activities but also contains links to updated policies, guidance documents, and background information, including a biosecurity self-assessment for the poultry industry, criteria for using ventilation shutdown as a depopulation method and a plan for how vaccine could potentially be used.
