The 2026 Trusted Pet Food List: Examining FDA’s Regulation of Diseased Meat in Pet Food

Introduction: A Consumer Guide in a Regulatory Landscape

On December 1, 2025, consumer advocate Susan Thixton published the 2026 List of Trusted Pet Foods through her website TruthAboutPetFood.com. The list names 45 brands that meet her organization’s rigorous safety and ingredient standards. Notably, no kibble products made the cut. Thixton’s project arrives amid ongoing debate about the U.S. Food and Drug Administration’s (FDA) oversight of pet food ingredients, particularly its policy allowing meat from diseased, disabled, or decomposing animals in pet food without mandatory disclosure.

The list positions itself as a direct response to what Thixton calls a “lack of transparency and enforcement” by the FDA. Yet the agency’s position is not without rationale: FDA officials have stated that current evidence does not demonstrate a safety risk from such ingredients, and that enforcement discretion allows the industry to maintain affordable pricing. This article examines both sides—the consumer advocacy movement pushing for stricter standards, and the regulatory and economic arguments that maintain the status quo.

Inside the 2026 List: What Makes a Brand Trustworthy

Thixton’s team evaluated more than 100 candidate brands before narrowing the selection to 45. The vetting process relies on five core criteria: ingredient quality (human-grade, organic, or humane meat sourcing); facility licensing (human food-grade versus pet food-grade); safety protocols (testing, supplier requirements, and disclosure of pesticide fumigation); packaging standards (recyclability, BPA disclosure); and transparency in sourcing.

The final list includes 22 cooked, 24 raw, 14 freeze-dried or dehydrated, 4 air-dried, 3 canned, and 2 veterinary diet products. No kibble brands were included, largely because most dry pet food manufacturers rely on rendered meals—a process that often uses animals that would not pass human food inspection. Geographic availability spans 42 brands in the United States, 13 in Canada, and 11 outside North America.

Thixton’s criteria represent a higher bar than current FDA requirements. For instance, human-grade certification requires that every ingredient and the facility itself meet all standards for human food production. According to the FDA, such standards are voluntary for pet food; the agency’s current framework focuses on ensuring pet food is “safe, wholesome, and properly labeled” under the Federal Food, Drug, and Cosmetic Act. Critics of the list argue that its strict criteria exclude many products that have never been linked to adverse health events in pets.

The Regulatory Gap: FDA’s Enforcement Discretion

The central controversy involves the FDA’s stance on diseased animals in pet food. In 2018, a Citizen Petition filed by Thixton and others requested that the FDA prohibit the use of meat from animals that are “diseased, disabled, or dead-on-arrival” in pet food. The FDA’s formal response stated: “We do not believe that the use of diseased animals, when properly processed, poses a safety concern and we intend to continue to exercise enforcement discretion.”

The agency’s rationale rests on several points. First, pet food manufacturing involves rendering or cooking at high temperatures that can kill pathogens. Second, the FDA notes that many diseases in livestock are species-specific and do not transmit to dogs or cats. Third, there is no documented outbreak of illness in pets directly linked to the use of diseased animal tissue in commercial pet food, though proving absence of harm is difficult. The FDA also points to cost implications: requiring human-grade ingredients would raise prices significantly, potentially reducing access to affordable nutrition for pet owners.

This regulatory gap is striking when compared to human food standards. For example, chicken sold for human consumption must come from a USDA-inspected bird that passed antemortem and postmortem inspection. Pet food labeled “chicken,” however, has no such requirement. The FDA’s position is not unique—similar allowances exist in some animal feed regulations internationally. Proponents of stricter rules argue that the policy creates an information asymmetry: consumers cannot know whether the meat in their pet’s food came from a healthy animal or a downer cow.

Economic Logic: Cost, Affordability, and Market Dynamics

Industry representatives argue that the use of non-human-grade animal tissue is essential to keeping pet food affordable. Rendering plants process millions of pounds of byproducts annually—including tissues that would otherwise be discarded. This stream supplies protein for mass-market pet food at a fraction of the cost of human-grade meat. According to the Pet Food Institute, the average American pet owner spends roughly $300–$500 per year on dry pet food. Shifting to human-grade ingredients could triple or quadruple those costs.

Large pet food corporations, such as Mars Petcare, Nestlé Purina, and Hill’s, rely on these supply chains. These companies maintain that their products meet nutritional standards set by the Association of American Feed Control Officials (AAFCO) and that their quality control processes ensure safety. They also note that the “diseased animal” narrative can be misleading—most rendered material comes from animals that passed USDA antemortem inspection but failed postmortem for minor reasons, such as bruises or abscesses, not from animals with communicable diseases.

Meanwhile, premium brands on Thixton’s list cater to a growing market segment of consumers willing to pay a premium for transparency. Companies like Open Farm, JustFoodForDogs, and The Honest Kitchen use human-grade ingredients and market themselves as ethical alternatives. This bifurcation creates a two-tier market: mass-market brands compete on price while premium brands compete on trust. Consumer advocacy efforts like Thixton’s list reinforce this divide but have not yet shifted mainstream regulation.

Long-Term Implications for Supply Chain and Consumer Trust

The regulatory divide has consequences beyond price. Demand for human-grade pet food has grown steadily, with the global pet food market projected to reach over $135 billion by 2030. As more consumers seek transparency, major manufacturers have begun investing in premium lines. Purina’s “Pro Plan” and Hill’s “Prescription Diet” have introduced products with higher-quality ingredients, though none meet Thixton’s strict human-grade standard.

Supply chains are adapting. Some rendering plants now separate high-quality byproducts for premium pet food, while lower-grade material goes to less demanding applications. However, the infrastructure to produce human-grade pet food remains limited. Most pet food facilities are not licensed for human food production, and retrofitting is costly.

Consumer trust is another variable. Surveys by the Pet Food Institute show that the vast majority of pet owners trust their brand’s safety, but awareness of the diseased animal issue is low. When informed, some consumers switch to premium brands, while others accept the risk based on cost. Thixton’s list provides a reference for those seeking alternatives, but it remains a niche resource.

Industry and FDA Perspectives

The FDA has defended its enforcement discretion on multiple grounds. In a 2021 follow-up response to the Citizen Petition, the agency reiterated that it “continues to evaluate the scientific evidence” and that “current data do not support a regulatory change.” The agency also noted that state feed control officials, who enforce AAFCO model regulations, provide additional oversight.

Industry groups argue that the existing system works. The Pet Food Institute states that “pet food is one of the most regulated food products in the United States,” citing FDA, AAFCO, and state-level requirements. They emphasize that all pet food must be safe and that ingredients are subject to contamination testing.

Critics, however, point out that the system lacks mandatory reporting of adverse events and that the FDA rarely inspects pet food facilities. A 2023 report by the Government Accountability Office found gaps in FDA’s pet food oversight, including limited inspection frequency and inconsistent enforcement. Thixton’s advocacy has pushed the issue into public view, but legislative changes remain elusive.

Conclusion: A Persistent Divide

The 2026 List of Trusted Pet Foods highlights a fundamental disagreement about what constitutes safe and ethical pet food. Thixton and her supporters argue that consumers deserve the same level of transparency for pet food as for human food. The FDA and industry maintain that current standards adequately protect animal health without imposing prohibitive costs.

Neither side fully resolves the tension. The FDA’s policy allows for affordable pet food, but leaves consumers unaware of ingredient origins. Advocacy lists empower informed choices, but apply only to a minority of products. As the pet food market evolves, the debate over diseased meat in pet food is unlikely to disappear—but for now, the regulatory gap persists.
