An ongoing investigation into federal administrative oversight reveals a systemic pattern of non-responsiveness, procedural stonewalling, and non-enforcement by the U.S. Food and Drug Administration (FDA) regarding pet food safety and labeling standards. Documents and communications compiled by leading pet food consumer advocate Susan Thixton—founder of TruthaboutPetFood.com and the Association for Truth in Pet Food—demonstrate that the agency’s Center for Veterinary Medicine (CVM) repeatedly fails to enforce statutory provisions mandate truthful labeling, transparent ingredient definitions, and public health disclosures.
Under the Federal Food, Drug, and Cosmetic Act (FD&C Act), all animal foods are legally required to be safe, manufactured under sanitary conditions, free of harmful substances, and truthfully labeled. However, formal administrative inquiries filed between 2022 and late 2026 reveal that the agency has effectively abandoned active enforcement on critical fronts. These include:
Permitting Deceptive Packaging: Allowing major commercial brands to display imagery of whole human-grade meats while the actual ingredients consist exclusively of heavily processed meat meals and rendered by-products.
Concealing Rendering Standards: Refusing to clarify how "tankage"—slaughterhouse material derived from condemned livestock—must be declared on consumer-facing ingredient panels.
Suppressing Epidemiological Data: Failing to provide complete statistical contexts regarding Highly Pathogenic Avian Influenza (HPAI) risks in non-raw commercial pet foods and outdoor feline environments.
Regulatory Limbo Post-AAFCO MOU: Stonewalling inquiries regarding the status of Pet Food Label Modernization guidelines following the expiration of the agency’s Memorandum of Understanding with the Association of American Feed Control Officials (AAFCO).
Procedural Delays in Citizen Petitions: Taking 1,333 days—more than seven times the statutory 180-day limit—to issue a rejection to a formal Citizen Petition, and subsequently ignoring requests for reconsideration.
The resulting administrative vacuum leaves millions of pet owners without critical safety information or legal recourse, exposing systemic vulnerabilities within America’s $140 billion commercial pet food supply chain.

*Note: May 29 inquiry year contextualized within administrative sequence.
Case Study 1: Misleading Product Imagery vs. Rendered Ingredients (Jan–Sept 2026)
On January 28, 2026, TruthaboutPetFood.com submitted a formal inquiry to the FDA regarding compliance with the FD&C Act’s "truthful labeling" requirement. The inquiry highlighted Meow Mix Original Choice Cat Food, a widely distributed product whose front packaging displays prominent imagery of a grilled chicken breast, a roasted turkey portion, and fresh fish fillets.
An examination of the ingredient list shows that the actual protein sources are heavily processed rendered meal fractions:
Chicken by-product meal
Turkey by-product meal
Salmon meal
Ocean fish meal
Advocates requested a regulatory explanation detailing how visual representations of whole, intact culinary meats comply with statutory prohibitions against false or misleading labeling when the product contains no such ingredients.
FDA Action: No response was provided.
Follow-Up: A second request sent on March 12, 2026, asking whether CVM would answer or provide a rationale for its silence, was similarly ignored. As of September 15, 2026, the agency has maintained total administrative silence.
Case Study 2: Slaughterhouse "Tankage" Identification Vacuum (July 2026)
On July 6, 2026, consumer advocates submitted an inquiry regarding slaughterhouse processing streams. Under USDA operations, condemned livestock and diseased animal parts unfit for human consumption are processed into a substance legally categorized as "tankage."
Advocates requested clarification on labeling regulations: When tankage produced in a USDA chicken slaughter facility enters the pet food manufacturing chain, how must it be designated on the consumer-facing label? Specifically, does federal policy permit tankage to be listed simply as "chicken" or "chicken meal"?
FDA Action: The FDA declined to respond or provide regulatory guidance on how condemned waste streams are labeled for retail sale.
Case Study 3: Avian Flu (HPAI) Data Suppression (Sept 2025)
On September 15, 2025, advocates challenged the FDA regarding its selective public messaging on Highly Pathogenic Avian Influenza (HPAI H5N1). While the agency issued public advisories warning against feeding raw pet food due to HPAI transmission risks, official USDA statistics indicated that since May 2022, felines that consumed raw pet food accounted for only 4% of 145 confirmed domestic cat cases.
The remaining 96% of infected domestic cats consumed non-raw diets or had undocumented environmental exposures. Advocates submitted a structured request asking:
What processing styles (e.g., commercial kibble) were consumed by the remaining 96% of infected felines?
What percentage of these cases involved indoor-only animals versus outdoor access?
Why was public advisory messaging restricted exclusively to raw diets while withholding exposure profiles for 96% of affected cases?
FDA Action: The FDA failed to answer any of the questions, withholding epidemiological context necessary for pet owners to assess food safety risks accurately.
Case Study 4: AAFCO Separation and Label Modernization Limbo (May 2025 – June 2026)
Following the regulatory separation between the FDA and the Association of American Feed Control Officials (AAFCO)—marked by the expiration of their longstanding Memorandum of Understanding (MOU)—advocates sought clarity on May 29, 2025, regarding the multi-year Pet Food Label Modernization (PFLM) initiative.
Advocates asked whether CVM would formally recognize and enforce the structural labeling changes developed under the PFLM framework.
FDA Response (June 2025): The agency sent a generic canned email citing a link to an FDA statement acknowledging the expired MOU. The link contained zero references to label modernization.
Follow-Up (June 5, 2026): Advocates reiterated the original question, pointing out that the provided link was irrelevant.
FDA Response: A few days later, CVM issued a one-sentence reply: "We would refer you to our previous response."
Case Study 5: The 1,333-Day Citizen Petition Delay (2022 – April 2026)
In 2022, advocates filed a formal Citizen Petition under 21 CFR 10.30, legally requiring the FDA to enforce federal statutory mandates concerning misleading ingredient terminology. Under federal regulations, the FDA is mandated to provide a final determination or interim response within 180 days.
FDA Response Time: The agency took 1,333 days (over 3.6 years) to render a formal decision, ultimately declining to enforce the statutory provisions cited.
Petition for Reconsideration: On April 13, 2026, advocates filed a Petition for Reconsideration pursuant to 21 CFR 10.33, presenting additional consumer research proving that pet owners are actively misled by current labeling standards. The filing requested a determination within 45 days.
Status as of September 15, 2026: 155 days post-filing, the agency has provided no response.

Federal law mandates that feed ingredients match their public representations. However, CVM exercises "regulatory discretion"—a policy mechanism through which federal authorities choose not to prosecute technical violations of the law. This practice permits feed manufacturers to use rendered animal tissue derived from diseased, dying, or condemned stock without explicit front-of-pack disclosure.
Rendered Meals vs. Whole Meats: Key Definitions
To understand the core issue in consumer deception, it is necessary to examine how ingredients are defined legally versus how they are marketed visually:
Ingredient Term
Legal Regulatory Definition
Visual Marketing Representation
Consumer Perception
Whole Meat(Chicken, Beef, Turkey)
Clean flesh derived from slaughtered mammals/poultry, limited to striated muscle tissue with natural accompanying fat/skin.
Intact roasted cutlets, raw steaks, fresh chicken breasts.
High-quality, human-grade whole muscle meat.
By-Product Meal
Rendered product derived from animal tissues, excluding added skin/feathers/horns, but inclusive of viscera, heads, feet, and underdeveloped eggs.
Intact roasted cutlets, fresh poultry fillets on retail packaging.
Dehydrated or ground whole meat portions.
Tankage / Condemned Material
Dried residues from animal tissues cooked in open or closed tanks, frequently including condemned slaughterhouse offal or dead-on-arrival stock.
Generic poultry/meat meal declarations on ingredient lists.
Standardized commercial protein meal.
HPAI Epidemiological Breakdown in Domestic Felines
The agency’s selective communication regarding Highly Pathogenic Avian Influenza (HPAI H5N1) risk vector data highlights significant gaps in public health reporting:
CONFIRMED CAT HPAI CASES (USDA DATA: MAY 2022 - SEPT 2025)
[4%] Raw Pet Food Exposure (Target of FDA Public Health Warnings)
███
[96%] Non-Raw Diet / Outdoor Access Vector / Undisclosed (No Public Warning)
████████████████████████████████████████████████████████████████████████████████
By issuing public alerts focused solely on the 4% raw food subset while failing to disclose or contextualize data for the remaining 96% of cases, the agency leaves pet parents without actionable guidance regarding environmental vector exposure or heat-processed food transmission risks.
Official Statements & Regulatory Vacuum
The agency’s institutional approach to consumer inquiries is illustrated by its written exchanges with advocacy groups. When questioned about the impact of the expired FDA-AAFCO Memorandum of Understanding on long-awaited labeling reforms, CVM provided a standard form response:
"Dear Ms. Thixton: Thank you for contacting FDA’s Center for Veterinary Medicine (CVM). We would refer you to [FDA Stakeholder Letter] in response to your below inquiry. Sincerely, AskCVM"
When advocates pointed out that the cited URL contained no information regarding the adoption status of the Pet Food Label Modernization guidelines, the agency reiterated its refusal to provide substantive details:
"We would refer you to our previous response."
This reliance on non-responsive administrative loops reflects a broader structural issue within CVM. By failing to clarify whether state feed officials, federal inspectors, or independent manufacturers hold primary jurisdiction over feed labeling, the agency creates an environment where deceptive marketing can continue unchecked.
Legal Discrepancy: Statutory Mandates vs. Administrative Delays
The procedural handling of Citizen Petitions further demonstrates this regulatory breakdown:
21 CFR § 10.30(e)(2) Statutory Requirement: The agency must respond to a petitioner within 180 days of receipt, either by approving, denying, or providing an interim explanation detailing why a decision cannot be reached.
FDA Action on 2022 Petition: The agency took 1,333 days to issue a response, exceeding the administrative deadline by more than 1,150 days.
21 CFR § 10.33 Reconsideration Standard: Although prompt administrative review is required, the agency has allowed the April 13, 2026 Petition for Reconsideration to sit unanswered for over 155 days.
Future Outlook & Implications for Pet Owners
Systemic Vulnerabilities in Pet Food Oversight
The agency’s unwillingness to answer basic public inquiries or enforce statutory labeling laws carries structural consequences for consumers, state regulators, and pet food manufacturers:
Erosion of Consumer Trust: As pet owners spend upwards of $140 billion annually on commercial pet foods, the inability to verify packaging claims undermines consumer confidence across the entire sector.
Regulatory Fragmentation Across States: Without clear federal guidance following the FDA-AAFCO separation, individual state departments of agriculture may interpret labeling rules differently, creating inconsistent standards across state lines.
Public Health and Biosecurity Exposure: Selectively releasing data on pathogens such as Avian Influenza limits the ability of veterinarians and pet owners to implement effective biosecurity measures.
Recommended Reforms and Regulatory Legal Action
To restore accountability and protect consumer interests, legal experts and public health advocates recommend the following structural reforms:
Targeted Congressional Oversight: House and Senate committees with jurisdiction over the FDA must hold oversight hearings regarding CVM’s exercise of "regulatory discretion" and its failure to enforce misbranding laws.
Mandatory Binding Response Deadlines: Enact statutory remedies under the Administrative Procedure Act (APA) that allow petitions to be automatically escalated to judicial review if CVM fails to act within the statutory 180-day window.
Visual Labeling Transparency: Implement strict guidelines prohibiting front-of-pack images of human-grade whole meats unless those specific ingredients constitute the primary protein source by weight.
Public Health Data Disclosures: Require the FDA and USDA to publish complete, unredacted epidemiological tracking data for zoonotic outbreaks like HPAI, detailing processing styles and environmental exposure vectors for all affected domestic animals.
Advocacy organizations, including the Association for Truth in Pet Food, have confirmed they will continue pursuing administrative appeals, public disclosures, and legal remedies to compel federal agencies to enforce the law as written. Until formal reforms are enacted, pet owners must remain cautious, critically evaluating product ingredient panels rather than relying on promotional front-of-pack graphics.
