The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has finalized amendments to the regulations governing the National Poultry Improvement Plan (NPIP). These changes were voted on and approved by industry delegates during the NPIP’s 2022 National Plan Conference and are designed to strengthen biosecurity, clarify requirements, and align the Plan with current industry practices.

Key updates include:

  • Conditioning indemnity for low pathogenicity avian influenza on adherence to approved biosecurity plans.
  • Clarifying and updating provisions related to NPIP participation, testing procedures, and voting requirements.
  • Aligning regulatory language with modern poultry production and disease-control practices.
  • Correcting editorial errors to improve regulatory clarity.
  • The NPIP is a cooperative Federal-State-industry program that helps prevent and control poultry diseases, ensuring flocks, hatcheries, dealers, and slaughter plants meet rigorous health and disease-prevention standards. Participation is voluntary; however, all flocks must first qualify as “U.S. Pullorum-Typhoid Clean” to access additional program benefits.
  • The amendments follow a public comment period on APHIS’ June 2024 proposed rule. These updates ensure that NPIP continues to serve as a trusted, science-based program that protects U.S. poultry health, strengthens disease prevention, and supports the long-term stability of the poultry sector.
