When a voluntary recall expands — not once, but twice — it signals something deeper than a single batch error. The February 2026 Go Raw LLC recall expansion involving Quest Diet Cat Food products isn't just a cautionary tale for one Utah-based company. It's a compliance roadmap for every pet food manufacturer navigating FDA's increasingly rigorous enforcement environment.
The lesson here is simple but critical: nutrient deficiency failures, particularly for heat-sensitive or processing-sensitive vitamins like thiamine (Vitamin B1), are among the most preventable — and most consequential — failures in pet food manufacturing. If your quality system isn't built to catch low thiamine before product ships, this recall is your wake-up call.
What Happened: The Go Raw LLC Recall Timeline
On February 17, 2026, Go Raw LLC of Cottonwood Heights, Utah, initiated a voluntary recall of a freeze-dried pet food product due to potentially low levels of thiamine (Vitamin B1). Less than two weeks later, on February 26, 2026, the company expanded that recall to include two additional lots of Quest Cat Food Chicken Recipe frozen products.
According to the FDA recall notice, the affected products presented potentially low thiamine levels — a deficiency that carries serious, sometimes fatal, health consequences for cats.
This recall expansion pattern — an initial action followed quickly by a broader scope — is a hallmark of inadequate finished product nutrient verification testing. When manufacturers rely solely on formulation estimates rather than end-product assay data, recalls tend to grow rather than resolve cleanly.
Why Thiamine Deficiency Is a Serious Cat Health Hazard
Thiamine (Vitamin B1) is an essential water-soluble vitamin that cats cannot synthesize endogenously. Unlike dogs and humans, cats have a particularly high metabolic thiamine requirement. Deficiency can develop within days to weeks of consuming thiamine-deficient food and progresses rapidly.
Clinical signs of thiamine deficiency in cats include: - Neurological symptoms: ataxia, circling, head tilt, seizures - Vestibular dysfunction - Cardiac abnormalities - Death if untreated
The FDA has issued multiple safety alerts over the years specifically regarding thiamine deficiency in cat food — this is not a new or obscure hazard. Thiamine is particularly vulnerable to degradation during thermal processing, prolonged storage, and exposure to sulfite preservatives, making it a well-known critical control point for pet food formulators.
Citation hook: Thiamine deficiency in cats can cause irreversible neurological damage within days of consuming deficient food, making it one of the highest-severity nutrient hazards regulated under FDA's pet food safety framework.
The Regulatory Framework: What FDA Requires for Pet Food Nutrient Compliance
21 CFR Part 501 — Pet Food Labeling
Under 21 CFR Part 501, pet food labels must not be false or misleading. If a product label declares or implies nutritional completeness (e.g., "complete and balanced"), the product must actually deliver those nutrients at the levels claimed. Failing to meet declared or implied nutrient levels can constitute misbranding under 21 U.S.C. § 343.
21 CFR Part 507 — Preventive Controls for Animal Food
This is the regulation at the heart of this recall. Effective September 17, 2016 (for larger businesses), 21 CFR Part 507 requires that animal food manufacturers — including pet food companies — implement a Food Safety Plan that includes:
- Hazard Analysis (21 CFR § 507.33): Identifying known or reasonably foreseeable hazards, including nutrient deficiencies
- Preventive Controls (21 CFR § 507.34): Implementing process controls, supplier controls, and verification activities to address identified hazards
- Monitoring Procedures (21 CFR § 507.39): Documenting that preventive controls are consistently applied
- Verification Activities (21 CFR § 507.47): Including product testing to verify that preventive controls are effective
- Corrective Action Procedures (21 CFR § 507.42): Procedures for when a preventive control is not properly implemented
Low thiamine in a finished cat food product is precisely the type of hazard that must appear in the hazard analysis under § 507.33. Thiamine loss during freeze-drying or freezing processes — the exact processing methods used by Go Raw LLC — is a known, documented risk that a competent hazard analysis would flag.
AAFCO Nutrient Profiles
The Association of American Feed Control Officials (AAFCO) publishes minimum nutrient profiles that define "complete and balanced" for cats. The 2026 AAFCO Cat Food Nutrient Profile specifies a minimum thiamine requirement of 5.6 mg/kg on a dry matter basis for adult maintenance. Products falling below this threshold that are labeled "complete and balanced" are non-compliant with both AAFCO standards and FDA labeling requirements.
Citation hook: Under 21 CFR Part 507, pet food manufacturers are legally required to identify nutrient deficiency risks — including thiamine loss from thermal or freeze-drying processes — in their written Food Safety Plans and implement verified preventive controls to address them.
Freeze-Dried and Frozen Pet Foods: A Higher-Risk Processing Category
It may seem counterintuitive that freeze-dried or frozen products — which avoid high-heat cooking — would have thiamine deficiency issues. But the risk profile is more nuanced:
| Processing Method | Thiamine Risk Factor | Primary Risk Mechanism |
|---|---|---|
| Retort/Canned (high heat) | High | Thermal degradation during sterilization |
| Extruded (dry kibble) | Moderate-High | Heat + oxidation during extrusion |
| Freeze-Dried | Moderate | Ingredient variability; formulation errors; oxidation during storage |
| Raw Frozen | Moderate | Ingredient sourcing variability; inconsistent raw material nutrient levels |
| Baked/Air-Dried | High | Heat exposure during drying |
For freeze-dried and raw frozen products, the primary thiamine risk is ingredient-level variability. Raw chicken, for example, has natural thiamine content that varies based on the bird's diet, age, and the specific tissue used (muscle meat vs. organ). Formulations that rely on raw ingredient nutrient tables rather than verified supplier Certificates of Analysis (CoAs) and periodic finished product assays are flying blind.
This is precisely the gap the Go Raw LLC situation appears to expose. When a recall expands to include frozen products alongside a freeze-dried product, it suggests the root cause may be at the ingredient sourcing or formulation verification level, not merely a processing anomaly.
The Five Compliance Failures That Drive Thiamine Recalls
After working with 200+ food and pet food clients at Certify Consulting, I've seen the same preventable gaps appear repeatedly in nutrient-related recalls:
1. Formulation-Only Verification (No Finished Product Testing)
Relying exclusively on recipe calculations without end-product laboratory assays. Nutrient databases provide averages — your actual ingredients may deviate significantly.
2. Absent or Inadequate Hazard Analysis for Nutrient Loss
Not identifying thiamine degradation as a hazard in the Food Safety Plan under 21 CFR § 507.33. This is non-negotiable for complete-and-balanced products.
3. Weak Supplier Controls
Purchasing ingredients without requiring and verifying CoAs that include relevant nutrient data. Under 21 CFR § 507.36(b), supplier controls must be commensurate with the risk of the ingredient.
4. No Statistical Process Control on Nutrient Testing Frequency
Testing one lot per year is insufficient for a high-velocity production line. Testing frequency should be risk-based and documented in the Food Safety Plan.
5. Recall Plan Gaps That Allow Recalls to Expand
Inadequate lot traceability and distribution records force companies to expand recalls as they discover additional affected product. A robust traceability system — required under 21 CFR § 507.55 — should allow precise, narrow scope recalls from the start.
Practical Compliance Guidance: Preventing Thiamine-Related Recalls
Step 1: Update Your Hazard Analysis Now
If your written Food Safety Plan does not explicitly address thiamine (and other heat/process-sensitive nutrients) as a known hazard, update it immediately. Reference scientific literature on thiamine stability in your processing method. This is both a regulatory requirement under 21 CFR § 507.33 and a legal protection in the event of an enforcement action.
Step 2: Implement Finished Product Nutrient Assay Protocols
Establish a testing schedule that includes HPLC or microbiological thiamine assay on finished product at a frequency tied to production volume and risk. At minimum, test each new formulation run, each new ingredient lot for high-risk inputs, and on a periodic (quarterly or semi-annual) surveillance basis.
Step 3: Require Nutrient-Specific CoAs From Ingredient Suppliers
For thiamine-sensitive formulations, require that your chicken, organ meat, or vitamin premix suppliers provide CoAs with thiamine values — not just proximate analysis. Include this as a written supplier approval requirement under 21 CFR § 507.36.
Step 4: Validate Your Vitamin Premix Inclusion Rate
If you're relying on a vitamin premix to deliver thiamine, validate that the premix is being added at the correct inclusion rate at the point of manufacture, not just on paper. Weigh verification logs, premix CoAs, and in-process controls should all align.
Step 5: Test Your Recall Plan With a Mock Recall
The Go Raw LLC recall expansion suggests traceability gaps. Conduct an annual mock recall exercise that tests your ability to isolate specific lots within two hours. Document the results and remediate any gaps found.
Citation hook: Pet food manufacturers relying solely on formulation calculations — without verified finished-product nutrient assays — are non-compliant with the verification requirements of 21 CFR Part 507 and exposed to the same recall trajectory seen in the Go Raw LLC thiamine recall expansion of February 2026.
Key Dates and Deadlines Relevant to This Recall
| Date | Event |
|---|---|
| September 17, 2016 | 21 CFR Part 507 effective for large businesses (preventive controls for animal food) |
| January 1, 2020 | FSMA full enforcement maturity across business size categories |
| February 17, 2026 | Go Raw LLC initial voluntary recall (freeze-dried product, low thiamine) |
| February 26, 2026 | Go Raw LLC recall expansion — two lots of Quest Cat Food Chicken Recipe frozen products added |
| Ongoing | FDA monitoring; affected consumers advised to stop use and contact veterinarian |
If you are a pet food manufacturer who has not reviewed your Food Safety Plan for nutrient deficiency hazards since the initial 21 CFR Part 507 compliance date, you are already operating under a compliance gap that FDA investigators can and do cite during inspections.
What Consumers and Veterinarians Should Know
If you have purchased Quest Diet Cat Food Chicken Recipe frozen products from Go Raw LLC with the lot numbers included in the February 26, 2026 recall expansion, the FDA advises:
- Do not feed the recalled product to your cat
- Watch for signs of thiamine deficiency: loss of appetite, vomiting, neurological symptoms, or seizures
- Contact your veterinarian immediately if your cat has consumed the recalled product and is showing any symptoms
- Return or discard the product per the company's recall instructions
Thiamine deficiency can be treated successfully with thiamine supplementation if caught early — time matters significantly with this type of deficiency.

Frequently Asked Questions
Q: Is low thiamine in pet food a violation of federal law? A: Yes. If a cat food product is labeled "complete and balanced" but contains thiamine below AAFCO minimum levels, it constitutes misbranding under 21 U.S.C. § 343 and may also represent a preventive controls failure under 21 CFR Part 507 if thiamine deficiency was not addressed in the manufacturer's Food Safety Plan.
Q: Does 21 CFR Part 507 require finished product nutrient testing? A: Yes, in practical terms. While the regulation specifies "verification activities" under § 507.47 rather than mandating a specific test, FDA expects that nutrient content — particularly for hazards identified in the hazard analysis — be verified through product testing. Relying solely on formulation calculations is unlikely to satisfy an FDA investigator reviewing your verification records.
Q: How often should pet food manufacturers test for thiamine? A: Testing frequency should be risk-based and documented in your Food Safety Plan. As a practical benchmark, test each new formulation batch, conduct periodic surveillance testing at least quarterly for high-risk products (freeze-dried, raw), and test after any ingredient supplier or formulation change. The key is that your rationale for testing frequency is documented and defensible.
Q: What should I do if my product may have low thiamine but I haven't shipped it yet? A: Implement a hold procedure immediately under your corrective action procedures (21 CFR § 507.42). Do not release the product until retesting confirms thiamine levels meet specifications. Document the hold, the retest, and the disposition decision. If distributed product is potentially affected, consult with FDA about voluntary recall procedures proactively — early engagement with FDA typically results in better outcomes than reactive recalls.
Q: Are freeze-dried and raw frozen pet foods at greater risk for nutrient recalls? A: These categories carry a different risk profile, not necessarily a greater one. High-heat processed foods risk thiamine loss during cooking; freeze-dried and raw foods face ingredient variability and formulation accuracy risks. Both require rigorous finished product verification. The Go Raw LLC recall expansion highlights that even minimal-processing products are not immune to nutrient deficiency failures.
