🐒⚠️ Colorado Cat Raw Food and H5N1 2026: What Colorado Cat Owners Must Know About the Savage Cat Food Case, CSU Testing and State Vet Guidance
Colorado was one of the first states where raw cat food was directly linked to confirmed H5N1 infections — and the testing that followed changed what we know about the virus in commercial pet food. In February 2025, a cat in Colorado contracted H5N1 after eating Savage Cat Food chicken packets. Colorado State University Laboratory tested sealed packets using PCR testing. The results were “non-negative” for H5N1. A formal recall followed. Separately, Colorado has 9+ confirmed H5N1 domestic cat cases total — including the landmark CDC MMWR cases of two strictly indoor cats infected via dairy farm worker fomites. The FDA issued a Jan 17, 2025 directive requiring all raw pet food manufacturers using uncooked poultry or cattle ingredients to include H5N1 as a known hazard in their food safety plans. There is no statewide Colorado ban on raw cat food as of March 2026 — but the state veterinarian, CSU, and the Colorado Department of Agriculture all recommend switching to commercially cooked food.
📊 Colorado H5N1 + Raw Cat Food: Key Facts
Colorado confirmed feline cases: 9+ domestic cats confirmed H5N1-positive (USDA APHIS NVSL data; CA 20, OR 14, CO 9 as of early 2025 reporting)
Savage Cat Food Colorado case: One Colorado cat contracted H5N1 and recovered after eating Savage Cat Food chicken lot 11152026. Colorado State University Lab PCR result: "non-negative." NVSL final virus isolation: negative for that lot — but a subsequent New York kitten case on the same lot confirmed avian flu. Formal recall: March 15, 2025.
FDA Jan 17, 2025 directive: Raw/unpasteurized poultry and cattle-derived cat food manufacturers must add H5N1 as a "known or reasonably foreseeable hazard" in all FSMA PCAF food safety plans.
Colorado indoor cat cases: Two strictly indoor cats infected via dairy farm worker fomites (CDC MMWR Feb 2025) — no raw food, no outdoor exposure. Both died.
No Colorado statewide raw food ban (March 2026): The state has not legislatively banned raw cat food. But AVMA, FDA, USDA, and Colorado state veterinarian all recommend switching to cooked commercial food during the ongoing outbreak.
🚨 Colorado cat owners: the two risk factors you can control right now are raw food and outdoor access. The third risk factor — fomite transmission from dairy farm workers — was first documented in Colorado (CDC MMWR, Feb 2025). If anyone in your household works with dairy cattle or poultry in Colorado, implement the clothing-change protocol before cat contact.
🧪 The Savage Cat Food Colorado Case: What CSU Found
The Colorado H5N1 case linked to Savage Cat Food represents one of the clearest examples of the raw food transmission chain documented in the U.S. In February 2025, Savage Pet was notified that one Colorado cat had contracted H5N1 after eating their chicken-formula product (lot 11152026). Colorado State University Veterinary Diagnostic Laboratory conducted PCR testing on sealed, unopened packets of the product. The PCR results were described as “non-negative” — meaning the test detected genetic material consistent with H5N1 but did not definitively confirm viable virus.
The product was sent to NVSL (National Veterinary Services Laboratory) in Ames, Iowa, for gold-standard virus isolation testing. On March 6, 2025, NVSL confirmed: negative for viable H5N1 virus in the tested lot. Savage Pet updated their consumer letter. However, on March 13, 2025, Savage Pet learned of a confirmed H5N1 case in a New York kitten fed from the same lot (11152026). This new confirmed case triggered a formal FDA recall on March 15, 2025. Cornell University tested samples of the product from New York City — confirmed positive. USDA NVSL confirmed the finding. CIDRAP: “Samples of the cat food from one lot were collected by the New York City Department of Health and tested by Cornell University and were positive.”
⚠️ The PCR vs. virus isolation distinction matters for Colorado cat owners: A PCR "non-negative" result detects viral RNA fragments — not necessarily viable, infectious virus. NVSL virus isolation tests for viable virus capable of causing infection. The Savage Cat Food Colorado lot was negative for viable virus in NVSL testing — but a different cat (New York kitten) on the same lot was confirmed infected. This illustrates the patchy nature of contamination in raw food lots and why the FDA directive requiring H5N1 as a known hazard in all raw food safety plans was necessary.
📋 FDA's Jan 17, 2025 Directive: What It Requires of Colorado Raw Food Brands
On January 17, 2025, the FDA's Center for Veterinary Medicine issued a formal determination under the FSMA Preventive Controls for Animal Food (PCAF) rule: manufacturers of cat and dog foods who use uncooked or unpasteurized materials derived from poultry or cattle must reanalyze their food safety plans to include H5N1 as a “known or reasonably foreseeable hazard.”
This applies to any Colorado-based raw pet food manufacturer and any brand distributed to Colorado retailers that uses raw poultry or cattle ingredients. The FDA update (September 30, 2025) reissued this directive for the fall migratory bird season, noting that “H5N1 detections typically increase throughout the United States in wild birds, with potential spread to commercial and backyard poultry flocks” during this period. Manufacturers implementing H5N1 preventive controls “will be taking an important step toward protecting cat and dog health and helping to prevent spread of H5N1.”

🏠 Colorado-Specific H5N1 Cat Risk in 2026
Colorado sits at a unique intersection of three H5N1 risk factors: active dairy cattle outbreaks (Colorado is one of 19 confirmed dairy states), significant migratory bird traffic through the state's wildlife corridors, and documented raw food contamination through the Savage Cat Food case. For Colorado cat owners, this creates a layered risk picture.
🔴 Raw Food Risk
Any raw or freeze-dried poultry-based food sourced from manufacturers using uncooked poultry or cattle ingredients carries H5N1 contamination risk during the ongoing outbreak. The FDA directive requires manufacturers to assess this risk, but enforcement of food safety plans is different from consumer-level product testing. Check the FDA Recalls & Withdrawals database at fda.gov/animal-veterinary before every raw food purchase.
🔴 Dairy Farm Worker Fomite Risk
Colorado documented the first evidence that H5N1 can reach strictly indoor cats through dairy farm worker household contacts (CDC MMWR Feb 2025). If anyone in your Colorado household works with dairy cattle or poultry: change clothes and shoes at the door, shower before prolonged cat contact, and keep cats away from work clothing storage areas. This protocol was recommended in the MMWR itself.
🟠 Outdoor/Wild Bird Risk
Colorado's wild bird H5N1 is endemic per CDC 2026 data. Outdoor cats with hunting behavior face ongoing exposure from scavenging infected birds. H5N1 is particularly prevalent during spring and fall migratory seasons. The AVMA recommends keeping cats indoors during the ongoing outbreak, citing the risk from wild bird contact.
✅ Colorado Cat Owner Action Plan
📋 Colorado-Specific Protective Steps
- Switch to commercially cooked cat food: AVMA, FDA, USDA, and Colorado state veterinarian all recommend this during the ongoing outbreak. Heat treatment (cooking) inactivates H5N1 virus. This is the single highest-impact change you can make for raw-feeding Colorado cats.
- Check FDA recalls before every purchase: fda.gov/animal-veterinary/safety-health/recalls-withdrawals. The Savage Cat Food and Northwest Naturals recalls both occurred rapidly. Bookmark this page.
- Implement door protocol for dairy/poultry workers: If anyone in your household works on Colorado dairy farms or poultry operations, change clothes and shoes before cat contact. The CDC MMWR Colorado cases are the only confirmed U.S. documentation of this fomite route.
- Keep cats indoors: Colorado has active H5N1 in wild birds and dairy cattle in 10+ counties. Outdoor and hunting cats in Colorado face direct exposure risk from infected wild birds and farm environments.
- Know the symptoms: Decreased energy and appetite progressing to neurological signs (lack of coordination, tremors, seizures). Respiratory signs may or may not be present. Call your vet before arriving — mention potential H5N1 exposure history.
- Contact Colorado resources if a cat develops symptoms: Colorado Department of Agriculture (CDA) State Veterinarian, Colorado State University VTH (Fort Collins — one of the labs that tested Savage Cat Food), and your primary care vet.
❓ Frequently Asked Questions
❓ Is raw cat food banned in Colorado in 2026?
No. There is no statewide Colorado ban on raw cat food as of March 2026. The Colorado Department of Agriculture and state veterinarian have issued guidance recommending against raw poultry-based food for cats during the H5N1 outbreak, consistent with AVMA, FDA, and USDA recommendations nationwide. The FDA's January 17, 2025 directive requires manufacturers to include H5N1 in their food safety plans, but this is a manufacturing regulation, not a retail or consumer ban. Colorado cat owners can still purchase raw food — but the recommendation from all major veterinary and regulatory authorities is to switch to cooked commercial food during the ongoing outbreak.
❓ The Savage Cat Food lot I had was tested negative by NVSL. Is it safe?
The Savage Cat Food Colorado lot (11152026) tested negative for viable H5N1 virus in NVSL virus isolation testing on the specific samples tested. However, a New York kitten fed from the same lot was subsequently confirmed infected — and Cornell University testing of NYC samples of the same lot came back positive. This demonstrates that contamination in raw food lots is not uniform: some packets in a lot may test negative while others contain the virus. The FDA recall for lot 11152026 was issued on March 15, 2025 after the New York confirmation. The recall has since been terminated by FDA. Colorado cat owners who still have Savage Cat Food from this lot should not feed it.
❓ My indoor-only Colorado cat has no exposure to raw food or farms. Can they still get H5N1?
Yes — though the risk is substantially lower than for outdoor cats or raw-feeding cats. The CDC MMWR documented two strictly indoor Colorado cats infected via dairy farm worker fomites. If no household member has dairy or poultry farm exposure, your indoor-only cat on cooked commercial food faces a lower risk profile than most Colorado outdoor cats. But zero-risk does not exist: H5N1 is endemic in Colorado wild birds, and the fomite transmission cases prove that strictly indoor cats can be reached through household contacts in high-exposure occupations.
