Executive Overview
Under the mandate of the Federal Food, Drug, and Cosmetic Act (FD&C Act), the U.S. Food and Drug Administration (FDA) is charged with ensuring that all animal feed—including pet food—is safe, produced under sanitary conditions, devoid of harmful substances, and truthfully labeled. However, an ongoing investigation into communication records between pet food consumer advocates and the FDA’s Center for Veterinary Medicine (CVM) reveals a pattern of administrative non-responsiveness, evasive guidance, and delayed regulatory action.
Prominent consumer advocacy organization TruthaboutPetFood.com, led by pet food advocate Susan Thixton, has documented a series of formal inquiries submitted to the regulatory agency between 2022 and 2026. These inquiries address critical issues concerning consumer deception on product labels, the industrial handling and labeling of condemned livestock materials, epidemiological transparency regarding Highly Pathogenic Avian Influenza (HPAI) risks, and the uncertain fate of national label modernization initiatives following structural policy shifts.
The findings highlight systemic transparency issues within the federal framework governing pet food safety, raising crucial questions regarding administrative accountability, statutory compliance, and public health communication.

+-----------------------------------------------------------------------------------+1. Labeling Misrepresentation and Visual Imagery Standards
On January 28, 2026, advocates submitted a inquiry regarding the enforcement of truthful labeling standards on commercial products, specifically citing Meow Mix Original Choice Cat Food. The front panel of the package displays illustrations of whole, cut animal proteins—including a grilled chicken breast, a roasted turkey portion, and fresh fish fillets. However, the ingredient list reveals that the actual primary protein sources consist of rendered meals: chicken by-product meal, turkey by-product meal, salmon meal, and ocean fish meal.
Advocates cited the FDA’s stated policy that animal foods must be "truthfully labeled" under the FD&C Act, requesting an explanation for why no regulatory action had been taken regarding the imagery. Following an absence of response, a formal follow-up was submitted on March 12, 2026. As of September 15, 2026, the FDA has provided no explanation or regulatory justification.
2. Label Identification of Rendered Condemned Livestock ("Tankage")
On July 6, 2026, advocacy representatives requested regulatory clarification regarding the processing of condemned materials from USDA slaughter facilities. Material rejected for human consumption is frequently rendered into an industrial product termed "tankage." The inquiry questioned how current regulations mandate the identification of such tankage on retail packaging—specifically, whether rendered condemned poultry from a USDA facility may be disclosed simply as "chicken" or "chicken meal."
The agency failed to provide a response, leaving the regulatory characterization of rendered condemned materials ambiguous for consumers.
3. Epidemiological Transparency Surrounding Avian Influenza (HPAI) Risks
On September 15, 2025, TruthaboutPetFood.com challenged the FDA regarding public health communications on Highly Pathogenic Avian Influenza (HPAI). While the FDA issued public warnings regarding raw pet food diets and HPAI contamination risks, official USDA statistics indicated that since May 2022, only 4% of 145 confirmed domestic feline cases involved cats that consumed raw food.
Advocates pressed the FDA for data regarding the remaining 96% of feline cases, inquiring:
- What proportion consumed processed kibble diets?
- What percentage were strictly indoor versus outdoor-access animals?
- Is the agency withholding exposure metrics that might indicate risks from commercial dry food or environmental vectors?
The agency did not provide the epidemiological breakdown or address the oversight inquiry.
4. Post-MOU Regulatory Framework and Label Modernization Policy
On May 29, 2025, following the termination of the longstanding Memorandum of Understanding (MOU) between the FDA and the Association of American Feed Control Officials (AAFCO), advocates requested clarification on the implementation status of the Model Pet Food Regulations under the Pet Food Label Modernization (PFLM) initiative.
The FDA’s Center for Veterinary Medicine responded within a week, directing the inquiry to a static webpage announcing the expiration of the FDA-AAFCO MOU. Because the linked document contained no information regarding PFLM standards, advocates resubmitted the question on June 5, 2026. The agency replied a few days later with a single statement: "We would refer you to our previous response."
5. Procedural Delays in Administrative Petitions
In July 2022, advocates filed a formal Citizen Petition under 21 CFR § 10.30, asking the FDA to enforce federal statutes governing misleading ingredient designations. Under federal administrative regulations, the FDA is required to respond to Citizen Petitions within 180 days.
The agency issued a formal refusal 1,333 days after the initial filing, stating it would not enforce the specific statutory interpretations requested. On April 13, 2026, advocates submitted a formal Petition for Reconsideration under 21 CFR § 10.33, submitting additional consumer research evidence and requesting a determination within 45 days. As of September 15, 2026 (155 days post-filing), the agency has issued no response.
Supporting Context and Regulatory Framework Analysis
To evaluate these communication gaps, it is necessary to examine the regulatory, structural, and legal metrics underlying pet food enforcement in the United States.

+---------------------------+ +---------------------------+Misbranding and the Graphic Representation Standard
The core conflict regarding product labeling centers on Section 403 of the FD&C Act [21 U.S.C. § 343], which dictates that a food is misbranded if its labeling is false or misleading in any particular. In human food processing, displaying fresh, whole ingredients on packaging when the product contains exclusively highly processed or secondary derivatives frequently triggers regulatory scrutiny or litigation.
In animal food regulatory practice, enforcement discretion has historically allowed manufacturers wide latitude. Whole muscle meat graphics are regularly used on packaging even when the underlying formulation relies exclusively on rendered protein meals or by-product meals. The FDA’s decline to issue public clarifications on products like Meow Mix reflects a continued institutional reliance on regulatory discretion over strict visual misbranding oversight.
Rendering Economics and "Tankage" Standards
The utilization of condemned materials in animal feed is tied to the economics of livestock slaughter and rendering. Under USDA regulations, livestock deemed unfit for human consumption (condemned due to disease, mortality prior to slaughter, or chemical residue) is directed to industrial rendering facilities.

[Pet Food Packaging Label] <--- Tankage Derivative <--- ["Chicken Meal"]While federal statutes technically restrict adulterated materials from entering the food supply, FDA Compliance Policy Guides (CPGs)—specifically CPG Sec. 675.400—have historically permitted rendered animal tissues from condemned sources to be utilized in animal feed unless a specific hazard is identified. The lack of standard consumer labeling distinguishing raw whole-tissue meals from processed condemned tankage leaves consumers unable to discern source material origins from the ingredient deck alone.
Avian Influenza Surveillance Data
The epidemiological data surrounding HPAI (specifically strain H5N1) highlights significant risk communication challenges. While raw pet food diets have faced public regulatory alerts due to the risk of unpasteurized meat carrying live virus, the vast majority of feline infection cases tracked by agricultural and public health databases involve animals with outdoor access (e.g., exposure to wild waterfowl) or farm environments with infected dairy cattle or poultry flocks.

Agency Response Patterns and Legal Framework
The administrative posture of the FDA Center for Veterinary Medicine relies heavily on automated referral mechanisms and enforcement discretion frameworks.

+----------------------+-------------------------------+----------------------------+
| Citizen Petitions | Extended Delay (1,333 Days) | Exhausts administrative |
| | | remedies through time. |
+----------------------+-------------------------------+----------------------------+When queried on policy transitions—such as the sunsetting of the FDA-AAFCO Memorandum of Understanding—the agency routinely employs standardized auto-responses referencing high-level policy declarations rather than addressing specific operational questions.
Under the Administrative Procedure Act (APA) [5 U.S.C. § 551 et seq.], federal agencies are required to conclude matters presented to them within a reasonable timeframe. However, the agency’s broad latitude in managing its enforcement priorities often insulates it from legal challenges regarding inaction, unless advocates pursue formal judicial review based on unreasonable delay or arbitrary administrative decisions.
Future Outlook and Consumer Advocacy Implications
The administrative barriers documented by consumer advocates highlight an evolving rift between regulatory authorities, pet owners, and independent industry oversight groups.

+-------------------------------+ +-------------------------------+- Fragmentation of Labeling Standards: Following the expiration of the FDA-AAFCO MOU, the enforcement of uniform labeling rules risks state-level fragmentation. Individual state feed control officials may enforce AAFCO’s Pet Food Label Modernization (PFLM) guidelines independently, creating inconsistent requirements across different states.
- Legal and Judicial Challenges: The deliberate decision by the FDA to take 1,333 days to address fundamental citizen petitions—and its ongoing non-response to Petitions for Reconsideration—opens pathways for administrative litigation under the APA for unreasonable agency delay.
- Growth of Consumer Verification Systems: Due to institutional opacity surrounding ingredient definitions and "tankage" sourcing, consumer groups like the Association for Truth in Pet Food are expanding independent, non-governmental verification systems and published product lists to evaluate manufacturing practices directly.
Advocacy organizations maintain that persistent public inquiries remain essential for holding regulatory agencies accountable. Without rigorous external scrutiny, the gap between statutory mandates and administrative enforcement will continue to leave consumers navigating an opaque marketplace.
