A nationwide recall affecting frozen and freeze-dried cat food sold in 21 states reveals how a single missing vitamin can cause seizures, neurological damage, and death in cats. The deficiency wasn’t caused by contamination or spoilage — it resulted from manufacturing failures that allowed products labeled as nutritionally complete to ship with dangerously low or undetectable levels of thiamine, an essential B vitamin cats cannot produce on their own.

On February 26, 2026, GO Raw LLC of Cottonwood Heights, Utah expanded a voluntary recall to include two additional lots of Quest Cat Food Chicken Recipe frozen products after laboratory testing confirmed thiamine levels fell below minimum safety thresholds established by federal regulators and veterinary nutritionists. The expansion followed an initial recall issued nine days earlier on February 17, 2026, covering freeze-dried products from the same brand.

The recalled lots — MCD25350 (best by 5/17/2027) and MCC25321 (best by 6/16/2027) — were distributed through specialty pet retailers in Colorado, Utah, Washington, Oregon, Pennsylvania, Rhode Island, Michigan, California, Texas, Illinois, Georgia, North Carolina, South Carolina, Florida, Minnesota, New York, Ohio, Wisconsin, Idaho, and Montana. GO Raw LLC also implemented a voluntary stop-sale on all Quest products until the thiamine deficiency issue is resolved across its product line.

Why Thiamine Deficiency Poses Serious Neurological Risks for Cats

Thiamine, also known as Vitamin B1, functions as a critical cofactor in glucose metabolism and nerve signal transmission. Unlike dogs or humans, cats require thiamine at particularly high metabolic rates and store minimal reserves in their bodies.

When dietary thiamine drops below required levels, cats can develop deficiency symptoms within days to weeks. Early warning signs include decreased appetite, vomiting, salivation, weight loss, and failure to grow in kittens.

As the deficiency progresses, neurological symptoms emerge. These include ventroflexion (a characteristic downward bending of the neck toward the floor), mental dullness, dilated pupils, vision changes, ataxia (wobbly or uncoordinated walking), circling behavior, falling, and seizures.

According to the FDA recall notice, thiamine deficiency is typically reversible if detected and treated promptly with thiamine supplementation. However, delayed diagnosis can result in permanent brain damage or death.

Veterinary professionals identified the deficiency after examining a cat exhibiting symptoms consistent with thiamine insufficiency. Subsequent testing of the food the cat had been consuming revealed extremely low thiamine levels, prompting federal safety authorities to issue warnings and the manufacturer to expand its recall.

How Specialty Diets Can Fail Nutritional Standards

Frozen and freeze-dried cat foods have grown in popularity as pet owners seek alternatives to conventional kibble and canned diets. These products are often marketed as premium or nutritionally superior options.

Despite avoiding high-heat cooking processes that can degrade heat-sensitive vitamins, freeze-dried and frozen foods face different nutritional risks. Thiamine content in raw chicken and organ meats varies based on the animal’s diet, age, and the specific tissue used. Manufacturers relying on average nutrient tables rather than verified laboratory analysis of actual ingredients can unknowingly formulate deficient products.

The Association of American Feed Control Officials (AAFCO) publishes minimum nutrient profiles defining what constitutes a complete and balanced cat food. For thiamine, AAFCO specifies a minimum of 5.6 milligrams per kilogram on a dry matter basis for adult cat maintenance diets.

Products falling below this threshold cannot legally be labeled as complete and balanced. Under federal law, pet food labels must not be false or misleading. A product claiming nutritional completeness that fails to deliver required nutrient levels constitutes misbranding.

The GO Raw LLC recall expansion suggests the root cause may involve ingredient sourcing or formulation verification gaps rather than isolated processing errors. When a recall grows to include both freeze-dried and frozen products, it often indicates systemic issues with how nutrient content is verified before products reach consumers.

This situation parallels broader discussions about healthy aging functional foods in human nutrition, where manufacturers face similar challenges ensuring formulated products deliver promised nutritional benefits.

What Pet Owners Should Do Immediately

Consumers who purchased Quest Cat Food Chicken Recipe frozen products should check their packages for the recalled lot numbers: MCD25350 (best by 5/17/2027) or MCC25321 (best by 6/16/2027). The products are sold in beige, two-pound zip-lock bags with a purple stripe and UPC 6-91730-17104-9. The lot code and best-by date appear printed on the front of each bag.

Stop feeding the recalled food immediately. Even if your cat appears healthy, thiamine deficiency can develop suddenly and progress rapidly once neurological symptoms begin.

Contact your veterinarian if your cat has consumed the recalled product, particularly if showing any symptoms of deficiency. Early intervention dramatically improves outcomes. Thiamine supplementation can reverse deficiency when administered before permanent neurological damage occurs.

Return the recalled product to the place of purchase for a full refund or replacement. GO Raw LLC stated that replacement inventory with reformulated products meeting nutritional standards is expected to begin reaching retailers around mid-March 2026.

For questions, consumers can contact GO Raw LLC directly at cs@gorawllc.com or by phone at 801-432-7478 (Monday through Friday, 9 a.m. to 4 p.m. Mountain Standard Time).

Pet owners managing the hidden health impacts of caring for animals with chronic conditions should pay particular attention to product recalls, as nutritional deficiencies can compound existing health challenges.

Regulatory Gaps Exposed by Recall Expansion

The pattern of an initial recall followed by expansion within nine days signals inadequate finished-product testing and traceability systems. When manufacturers discover additional affected lots after issuing an initial recall, it typically indicates they did not have complete visibility into which production runs were impacted by the underlying deficiency.

Federal regulations under 21 CFR Part 507 require animal food manufacturers to implement preventive controls, including hazard analysis identifying known or reasonably foreseeable nutritional deficiencies. Thiamine loss during processing or ingredient variability represents a documented, well-established risk that must be addressed in a manufacturer’s food safety plan.

Companies must also establish verification activities to confirm that preventive controls effectively address identified hazards. For thiamine-sensitive formulations, this typically requires finished-product laboratory testing at frequencies tied to production volume and risk level — not just reliance on formulation calculations.

Shantel Goodrich, LVT, Vice President of Operations at GO Raw LLC, stated in the company announcement: “We take the safety and well-being of pets extremely seriously. Rather than risk any potential concern, we made the decision to remove the affected product from the market and replace it with products we are confident meet our nutritional standards.”

The company indicated it launched a comprehensive investigation in early February 2026 after becoming aware of low thiamine levels, reviewing formulation specifications, raw ingredient suppliers, and processing procedures. Retailers were instructed to remove affected products immediately.

This recall highlights how even well-intentioned manufacturers can face serious compliance failures when nutrient verification protocols rely on theoretical calculations rather than empirical testing of actual finished products.

Frequently Asked Questions

What are the first symptoms of thiamine deficiency in cats?

Early symptoms include decreased appetite, vomiting, salivation, weight loss, and lethargy. These signs can appear subtle and may be mistaken for minor digestive upset. As deficiency progresses, neurological symptoms develop, including loss of coordination, unusual head positioning with the neck bent downward, dilated pupils, vision changes, circling, falling, tremors, and seizures. Contact a veterinarian immediately if your cat consumed recalled food and exhibits any of these symptoms.

Can cats recover from thiamine deficiency?

Yes, if treated promptly. Thiamine deficiency is typically reversible when diagnosed early and treated with thiamine supplementation administered by a veterinarian. However, delayed treatment can result in permanent neurological damage or death. The speed of intervention matters significantly — once advanced neurological symptoms appear, the window for full recovery narrows. Cats showing any symptoms after consuming recalled food require immediate veterinary evaluation.

What if my cat ate recalled Quest cat food but shows no symptoms?

Contact your veterinarian to discuss monitoring and potential testing. Thiamine deficiency develops over time with continued consumption of deficient food. A cat that ate small amounts may not develop clinical symptoms, while one that consumed the food as a primary diet for weeks faces higher risk. Your veterinarian can assess your cat’s specific exposure level and determine whether preventive thiamine supplementation or monitoring is appropriate.

Conclusion: Nutritional Precision Matters in Specialty Pet Foods

The GO Raw LLC recall serves as a critical reminder that premium marketing claims and minimal processing methods do not automatically guarantee nutritional adequacy. A vitamin measured in milligrams per kilogram can mean the difference between a healthy cat and one facing seizures and permanent brain damage.

As specialty pet diets continue growing in market share, manufacturers face increasing responsibility to verify that products actually deliver the nutrition their labels promise. For thousands of cat owners across 21 states, this recall transformed an invisible nutritional gap into a visible crisis requiring immediate action to protect their animals from serious harm.
