National Poultry Improvement Plan and Auxiliary Provisions

AGENCY:

Animal and Plant Health Inspection Service, USDA.

ACTION:

Final rule.

SUMMARY:

We are amending the regulations governing the National Poultry Improvement Plan (NPIP). These amendments, among other things, condition indemnity for low pathogenicity avian influenza on adherence to biosecurity plans, clarify existing provisions of the regulations, fix editorial errors, and align the regulations more closely with current producer practices. These changes were voted on and approved by the voting delegates at the NPIP's 2022 National Plan Conference.

DATES:

Effective October 30, 2025.

SUPPLEMENTARY INFORMATION:

Background

The National Poultry Improvement Plan (NPIP, also referred to below as "the Plan") is a cooperative Federal-State-industry mechanism for controlling certain poultry diseases. The Plan consists of a variety of programs intended to prevent and control poultry diseases. Participation in all Plan programs is voluntary, but breeding flocks, hatcheries, and dealers must first qualify as "U.S. Pullorum-Typhoid Clean" as a condition for participating in the other Plan programs.

The Plan identifies States, independent flocks, hatcheries, dealers, and slaughter plants that meet certain disease control standards specified in the Plan's various programs. As a result, customers can buy poultry that has tested clean of certain diseases or that has been produced under disease-prevention conditions.

The regulations in 9 CFR parts 56, 145, 146, and 147 (referred to below as "the regulations") contain the provisions of the Plan. The Animal and Plant Health Inspection Service (APHIS) amends these provisions from time to time to incorporate new scientific information and technologies within the Plan, and to ensure the plan reflects changes to the poultry industry itself.

On June 11, 2024, we published in the Federal Register (89 FR 49107-49118, Docket No. APHIS-2022-0056) a proposal  (1) to amend the regulations by updating and clarifying several provisions, including those concerning NPIP participation, voting requirements, testing procedures, and standards.

We solicited comments concerning our proposal for 60 days ending August 12, 2024. We received eight comments by that date. The comments were from three private citizens, a State department of agriculture, an organization representing turkey production within the United States, an organization representing egg production within the United States, an organization representing State agricultural interests, and an industry group.

Two commenters supported the rule, and one was generally opposed. Other commenters did not articulate an opinion regarding the rule overall but commented on various provisions.

We discuss the comments that we received below, by topic.

General Opposition

One commenter asserted that the proposed rule is excessive, would prove impracticable for domestic producers, and would result in greater importation of foreign poultry products.

The commenter provided no evidence in support of these contentions. The provisions of the proposed rule were largely voluntary and were advanced by the industry itself at the NPIP's 2022 National Plan Conference as being in the industry's best interests.

Comment Regarding Alternative Requirements for Breeders

One commenter suggested that a number of certifications for breeders were cost-prohibitive for small-scale rare and exhibition bird breeders. Specifically, the commenter stated that it could adhere to the testing requirements for U.S. Pullorum Typhoid (PT) clean status, but other certifications for highly pathogenic avian influenza (HPAI) involved cost-prohibitive testing. However, the commenter stated that it had a "closed flock," that did not augment the flocks through external additions but solely through on-site farm breeding. Based on its understanding of the relevant data, the commenter stated that there was little evidence of vertical transmission of HPAI from hatching eggs to adult birds in such closed production systems. The commenter inquired if we would consider regulatory revisions to clarify that small-scale rare and exhibition bird hatching eggs present a low risk of HPAI transmission.

The commenter claimed difficulty obtaining testing materials due to limited availability from a single manufacturer. The commenter suggested adding regulations that offer options that allow more flexibility when the supply of testing materials is low to reduce breeder burden.

The only prerequisite for NPIP participation is the Pullorum Typhoid (PT) Clean classification. Additional classifications such as HPAI testing and its related costs are voluntary. With regard to the regulatory revisions suggested by the commenter, § 147.44 of the regulations sets forth a submission process for proposed changes to the regulations. Under the terms of that section, under ordinary circumstances, proposals for changes to the regulations should go through the Biennial Conference for consideration, and should be submitted at least 150 days prior to the meeting, with allowance for proposals submitted closer to the date of the meeting to be entertained. Outside of this process, the NPIP General Conference Committee (GCC) may recommend changes to the regulations when postponing the changes until the next Biennial Conference would seriously impair the operation of NPIP. APHIS may initiate changes of our own accord if we determine them to be necessary and in the public interest. We do not consider it in the public interest to obviate the process set forth in § 147.44 of the regulations to initiate the changes suggested by the commenter. As a result, we encourage the commenter to submit the suggested changes through the process set forth in § 147.44 of the regulations.

The commenter also stated that online marketplaces were functioning as a means of circumventing regulations governing the shipment of hatching eggs.

This concern is outside the scope of the regulations and the jurisdiction of NPIP.

Comments Regarding Biosecurity Plans

9 CFR part 56 contains our regulations governing the payment of indemnity for low pathogenicity avian influenza (LPAI). The regulations currently require States to maintain initial State response and containment plans (ISRCPs) in order for producers in the State to be eligible for indemnity and/or compensation for 100 percent of eligible costs under the regulations. The regulations further require that each ISRCP must contain a minimum biosecurity plan to be followed by all producers in the State. In our proposed rule, we proposed to clarify that the biosecurity plan is not required for producers below size thresholds for inclusion in the NPIP. However, we also proposed revising the ISRCP requirements to require States to determine that the biosecurity plans are in place and being followed and to require States to audit the plans to ensure that the plans are in compliance with the NPIP Program Standards.

Two commenters addressed our proposed requirement to have States ensure that biosecurity plans are in place and being followed. First, they suggested voluntary versus mandatory biosecurity plans for flocks in ISRCP due to the lack of resources to enforce such requirements.

Although we understand the limited resources noted by the commenters, as we stated in the proposed rule, the regulations already require that ISRCPs include a minimum biosecurity plan followed by all poultry producers. Our proposed regulatory revisions were to ensure that this existing ISRCP requirement, which has been in effect since 2006, is, in fact, being carried out and producers in the State are in fact following the minimum biosecurity plan. As we noted in the 2006 interim rule that established the requirement (71 FR 56302-56333, Docket No. APHIS-2005-0109), producer biosecurity plans are a necessary component for APHIS to have confidence that a State is fully capable of determining whether H5/H7 LPAI is present in flocks that participate in NPIP within the State and taking action to respond to any outbreaks of LPAI that may occur within the State.

While APHIS is committed to working with Official State Agencies (OSAs) to lessen enforcement burden, the above comments suggest States were not enforcing the requirement. This underscores, rather than undermines, the need for the regulatory revisions in the proposed rule.

One commenter expressed concerns regarding farm auditing of biosecurity plans. The commenter inquired about provisions for situations ( e.g. outbreaks, lack of resources, etc.) when conducting on-site farm audits would not be possible.

We acknowledge that historically, biosecurity audits for both HPAI and LPAI have been paper-based, and evaluated a producer's biosecurity plans against the biosecurity principles contained in NPIP Program Standard E at least once every two years in order to review documentation and ensure biosecurity compliance. However, while a December 2024 interim rule (89 FR 106981-106996, Docket No. APHIS-2023-0088) revised our HPAI indemnity regulations to require on-premises biosecurity audits for certain producers as a condition of indemnification, APHIS will continue to use paper-based audits within the context of its LPAI indemnity regulations.

APHIS believes that continued use of paper-based audits for LPAI is justified. HPAI, unlike LPAI, is a foreign animal disease with a high mortality rate. Accordingly, the goals for biosecurity plans within the two programs differ. As stated above, within APHIS' LPAI control program, producer biosecurity plans are a necessary component for APHIS to have confidence that a State is fully capable of determining whether H5/H7 LPAI is present in flocks that participate in NPIP within the State and taking action to respond to any outbreaks of LPAI that may occur within the State. Within the context of the HPAI program, biosecurity plans are necessary to ensure that all possible sources of introduction of HPAI onto a premises are addressed and mitigated. The former effort can be conducted through paper-based audits, the latter effort cannot.

Comments Regarding Program Standard E

As we mentioned above, Program Standard E in the NPIP Program Standards articulates biosecurity principles that are used both within the context of APHIS' HPAI and LPAI control programs. Two commenters stated that the principles in Program Standard E are widely used within NPIP as both the template for producer biosecurity plans and as the baseline for checklists used by OSAs in order to evaluate those plans, and that changes to Program Standard E could have cascading implications.

We understand the commenters' concerns, however, the changes to Program Standard E that we proposed were not to the principles listed in that standard and as such, the commenters' concerns are outside the scope of this rule.

Timelines and Publishing Recommendations

One commenter noted that § 147.48 of the regulations requires APHIS to publish the recommendations of an NPIP Biennial Conference in the Federal Register within 14 months following the Biennial Conference, and pointed out that this did not occur with the proposed rule. The commenter indicated that a practical ramification of the delayed publication of the proposed rule was that the 2022 recommendations had not been codified prior to the submission date for regulatory changes for the 2024 Biennial Conference. The commenter stated that this created logistical challenges because the status of the 2022 Biennial Conference recommendations was not yet known at the time of the submission deadline. The commenter exhorted APHIS to adhere to the 14-month deadline in the future to avoid such complications going forward and expressed concerns regarding the regulations pertaining to publication within a 14-month timeframe for conference recommendations in the Federal Register . First, the commenter emphasized the significance of timeliness for the proper review, approval, and circulation of NPIP provisions prior to the next NPIP Biennial Conference proposal submission deadline. Then, the commenter discussed practical challenges faced by the GCC when the recommendations are not published before the Biennial Conference including a slower rate of accepting proposal changes for future regulatory revisions when the fate of previous recommendations remained unknown. In short, the commenter urged the prioritization of any 2024 NPIP Biennial Conference recommendation reviews to assist with efficiency.

We recognize the commenter's concerns regarding the timeliness of the proposed rule, and will strive to adhere to the 14-month deadline going forward. However, factors outside of the Agency's control can influence publication timelines. For example, the 2022-2024 HPAI outbreak in poultry was the largest animal health emergency in U.S. history and required widespread and prolonged deployment of APHIS personnel with avian health experience.

Lastly, upon review of the proposed rule, we have identified some minor typographical and syntactical errors within its regulatory text. In this rule, we have corrected them to ensure the regulatory text is accurate and reflects Agency intent.

Therefore, for the reasons given, we are adopting the proposed rule as a final rule, with the changes noted above.

Executive Orders 12866 and Regulatory Flexibility Act

This final rule has been determined to be not significant for the purposes of Executive Order 12866 and, therefore, has not been reviewed by the Office of Management and Budget. Further, because this rule is not significant, it is not a regulatory action under Executive Order 14192.

This rulemaking will result in various changes to regulations in 9 CFR parts 56, and 145 through 147, modifying provisions of the NPIP. The modifications were recommended by the NPIP General Conference Committee (GCC), which represents cooperating State agencies and poultry industry members and advises the Secretary on issues pertaining to poultry health. These amendments will, among other things, condition indemnity for LPAI on adherence to biosecurity plans, clarify existing provisions of the regulations, fix editorial errors, and align the regulations more closely with current producer practices.

The establishments affected by this rulemaking-principally entities engaged in poultry production and processing-are predominantly small by Small Business Administration standards. In those instances in which an addition or modification potentially results in a cost to certain entities, we do not expect the costs to be significant. This rule embodies changes decided upon by the NPIP GCC on behalf of Plan members, that is, changes recognized by the poultry industry as in their interest. We note that NPIP membership is voluntary.

Under these circumstances, the Administrator of the Animal and Plant Health Inspection Service has determined that this action, if promulgated, will not have a significant economic impact on a substantial number of small entities.

Executive Order 12372

This program/activity is listed in the Catalog of Federal Domestic Assistance under No. 10.025 and is subject to Executive Order 12372, which requires intergovernmental consultation with State and local officials. (See 2 CFR chapter IV.)

Executive Order 12988

This final rule has been reviewed under Executive Order 12988, Civil Justice Reform. This rule: (1) Preempts all State and local laws and regulations that are in conflict with this rule; (2) has no retroactive effect; and (3) does not require administrative proceedings before parties may file suit in court challenging this rule.

Paperwork Reduction Act

In accordance with section 3507(d) of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq. ), the reporting, recordkeeping, and third-party disclosure requirements described in this final rule are currently approved by the Office of Management and Budget (OMB) under OMB control numbers 0579-0007 and 0579-0440.

Samples for official tests shall be collected by an Authorized Agent, Authorized Testing Agent, or State Inspector and tested by an authorized laboratory, except that the stained antigen, rapid whole-blood test for pullorum-typhoid may be conducted by an Authorized Testing Agent or State Inspector. Testing must be conducted as specified within the Subpart Plan program, with at least 1 bird tested from each pen and unit in the house and a minimum of 30 birds tested per house. The ratio of samples collected from male and female birds must be representative of birds throughout the house and flock. In houses containing fewer than 30 birds other than ostriches, emus, rheas, and cassowaries, all birds in the house must be tested, unless otherwise specified within the Plan program.

(ii) Reactors to the standard tube agglutination test (in dilutions of 1:50 or greater) or the microagglutination test (in dilutions of 1:40 or greater) shall be submitted to an authorized laboratory for bacteriological examination. If there are more than four reactors in a flock, a minimum of four reactors shall be submitted to the authorized laboratory; if the flock has four or fewer reactors, all of the reactors must be submitted. Bacteriological examination must be conducted in accordance with part 147 of this subchapter (within the Program Standards document, Program Standard B addresses bacteriological examination procedures; alternatives to the program standards may also be approved by the Administrator under § 145.73). When reactors are submitted to the authorized laboratory within 10 days of the date of reading an official blood test named in paragraph (a)(6)(i) of this section, and the bacteriological examination fails to demonstrate pullorum-typhoid infection, the Official State Agency shall presume that the flock is determined not to be infected with Salmonella Pullorum or Salmonella Gallinarum.
