Congress’s pet food labeling mandate still isn’t finished

CURRENT FULL VERSION: Nearly 17 years after Congress ordered FDA to update pet food labeling standards, the agency still has not completed that federal mandate. The requirement came from the Food and Drug Administration Amendments Act of 2007, which told HHS and FDA to establish, by regulation, ingredient standards, processing standards, and updated labeling standards for pet food no later than September 27, 2009. Recent reporting from Truth about Pet Food has put that unfinished work back in focus, arguing that the delay has left major transparency questions unresolved. (law.cornell.edu)

The history matters. Congress acted after the 2007 pet food crisis, when contamination concerns exposed weaknesses in oversight and traceability. FDA’s own one-year implementation update shows the agency did open a docket and hold a public meeting in 2008 on the standards required by Section 1002(a). But while FDA later expanded broader animal food oversight through FSMA and continues to regulate pet food under existing adulteration, misbranding, and labeling authorities, the specific FDAAA labeling rule Congress called for remains unfinished.

In the meantime, the practical labeling system for pet food has continued to rest on existing FDA requirements plus AAFCO model regulations. FDA says labels must identify the product, provide net quantity, manufacturer or distributor information, and list ingredients in descending order by weight. FDA also notes that some animal food ingredients may use collective names under federal regulation, while AAFCO says its model regulations address pet food-specific labeling issues but do not carry legal force unless adopted by states. That’s a key distinction in this debate: there is a functioning regulatory structure, but not the fully updated federal labeling standard Congress explicitly required. (fda.gov)

That gap helps explain why advocates such as Susan Thixton continue to focus on ingredient disclosure, especially around lower-grade or condemned source materials and whether labels give veterinarians and pet parents enough information to judge ingredient quality. In one recent example, Thixton argued that meat or poultry materials can be conspicuously marked as “inedible” or “not intended for human food” earlier in the USDA-regulated supply chain, including condemned material and animals described in industry shorthand as 4D, yet still appear on finished pet food labels under conventional ingredient names such as chicken or beef once they enter the pet food system. Her framing is more adversarial than that used by regulators, and some of the underlying quality implications are contested, but the narrower point about disclosure limits is relevant to the labeling debate. FDA has not published the long-promised federal labeling rule, while AAFCO and industry have moved ahead with their own modernization process. (truthaboutpetfood.com)

Thixton also says her organization petitioned FDA in 2022 to require pet food labels to disclose when ingredients came from condemned, inedible, or diseased animal material, and that FDA later declined the request, saying such disclosure was not necessary to maintain food integrity or meet consumer expectations. We have not independently reviewed the full petition record here, but the episode underscores the broader policy fault line: whether current ingredient naming rules give consumers and clinicians enough meaningful information about source material, or whether FDA views the existing framework as sufficient so long as the finished product meets applicable animal food requirements.

Industry and regulatory groups have largely framed the next phase around AAFCO’s Pet Food Label Modernization project rather than FDA rulemaking. AAFCO says the effort began in 2015, produced new model regulations in the 2024 Official Publication, and is intended to modernize labels and improve consumer understanding. AAFCO also recommended six years of enforcement discretion tied to the 2024 publication, which puts full implementation around 2030. The Pet Food Institute has backed that effort, saying the model changes better align pet food labels with human food-style information panels and should gradually appear on packaging before the end of the decade.

Why it matters: For veterinary professionals, this is a label literacy story with clinical implications. Nutrition conversations increasingly involve elimination diets, obesity management, renal support, GI sensitivity, and client questions about ingredient sourcing and processing. Yet the information clinicians can pull from a label is shaped by overlapping federal and state frameworks, not one updated national standard. That can complicate discussions when pet parents assume labels answer more than they actually do, or when practices need to compare products across manufacturers using different presentation styles. (fda.gov)

There’s also a trust issue. FDA emphasizes that labels must be truthful and not misleading, and AAFCO’s modernization project is explicitly aimed at clearer communication. But the fact that Congress required an updated federal rule in 2007, and that the market is instead moving through state adoption of model standards effective through 2030, may reinforce concerns from both clinicians and pet parents that pet food transparency evolves slowly and unevenly. The dispute over whether ingredients previously identified in the supply chain as inedible or condemned should be disclosed more explicitly on finished labels adds another layer to that trust question, even if regulators and advocates disagree on how far labeling should go. For practices, that likely means continued reliance on manufacturer technical support, independent nutrition expertise, and careful client counseling rather than label text alone. (law.cornell.edu)

What to watch: The next signal will be whether FDA reopens or advances formal rulemaking under 21 U.S.C. § 2102, whether it takes any further action on requests for disclosure of condemned or inedible source materials in pet food ingredient statements, or whether AAFCO’s modernization track effectively becomes the de facto national standard as more states adopt the 2024 model regulations ahead of the July 2030 transition point cited by state regulators.
