The Standard Why It Matters Process Compare Science FAQ Verify a Product
The most rigorous certification in pet nutrition

Your pet eats the same thing every day. Make sure it's actually clean.

Clean Bowl Certified is the independent, non-profit certification that tests pet food against 1,200+ contaminants and adulterants — from mycotoxins and heavy metals to synthetic preservatives and undeclared fillers. If it wears our seal, every ingredient has been proven safe and every nutritional claim has been verified.

What it takes to earn the CBC seal

Six pillars. A pet food must pass all six. There is no partial certification, no tiered system, no "good enough." It either meets the standard or it doesn't.

🧪

1. Contaminant Screening

Zero detectable levels — at parts-per-billion sensitivity — of mycotoxins (aflatoxins B1/B2/G1/G2, ochratoxin A, fumonisins, vomitoxin, zearalenone), heavy metals (lead, cadmium, mercury, arsenic), pesticides (200+ compounds), acrylamide, melamine, cyanuric acid, and pentobarbital. Every ingredient lot is tested before production.

MycotoxinsHeavy metalsPesticidesAcrylamideMelaminePentobarbital
🥩

2. Ingredient Integrity

Full species-of-origin verification via PCR DNA testing for all animal proteins — no undeclared species, no rendered euthanized animals, no 4-D meat (dead, dying, diseased, disabled). "Meat meal" and "animal by-product" must be fully specified. Grain sources tested for GMO content and glyphosate residue. No artificial colors, flavors, or sweeteners.

PCR species IDNo 4-D meatNo undeclared fillersGlyphosate testingNo artificials
🦠

3. Microbiological Safety

Every production batch tested for Salmonella spp., Listeria monocytogenes, E. coli O157:H7, Campylobacter jejuni, Clostridium perfringens, and total Enterobacteriaceae. For raw products: additional testing for Toxoplasma gondii and Neospora caninum. Processing must demonstrate a 5-log pathogen reduction step.

4. Nutritional Verification

Guaranteed analysis claims are independently verified — protein, fat, fiber, moisture, ash, and micronutrient profiles tested against label claims. AAFCO or FEDIAF nutrient profile compliance confirmed through complete amino acid, fatty acid, vitamin, and mineral panel. Taurine levels verified for grain-free formulations (dilated cardiomyopathy risk screening).

5. Manufacturing Integrity

Every production facility undergoes an unannounced on-site audit. Requirements: dedicated clean lines, HACCP plan verification, cold-chain integrity for raw/frozen products, allergen cross-contact prevention, equipment sanitation logs, and full batch traceability from ingredient receipt to finished product. Co-packers are audited separately for each brand they manufacture.

6. Continuous Surveillance

Certification is not permanent. Every production batch must pass contaminant screening before release. Annual full-panel re-certification at ISO 17025 labs. Quarterly retail spot-checks — CBC purchases products anonymously from stores and online, tests them, and publishes results. A single failed spot-check triggers immediate public suspension and a consumer alert.

Pet food labeling is broken

The regulatory gap between what pet food labels say and what's actually in the bag is wide — and it's your pet who pays the price.

of commercial pet foods tested failed CBC contaminant screening on their first attempt

    "Human-grade" has no legal definition in pet food

    The term is a marketing invention with zero regulatory backing. Any brand can claim "human-grade" regardless of sourcing, processing, or facility conditions. CBC verifies actual ingredient quality through independent testing — not marketing copy.

    Rendered by-products can contain euthanized animals

    Rendering plants process shelter animals, roadkill, and livestock that died of disease. Pentobarbital — the drug used for euthanasia — has been detected in commercial pet foods. CBC requires PCR species verification and pentobarbital screening for every animal-protein ingredient.

    Mycotoxin contamination is widespread and underreported

    Aflatoxins and fumonisins are common in grain-based pet foods, especially those using corn, wheat, or rice by-products. Chronic low-level exposure is linked to liver damage, immune suppression, and cancer in dogs and cats. Most pet foods are never tested for the full mycotoxin panel.

    Grain-free ≠ safer — and may carry its own risks

    Grain-free formulations often replace grains with legumes and potatoes, which have been associated with canine dilated cardiomyopathy (DCM) in FDA investigations. CBC verifies taurine levels, amino acid bioavailability, and doesn't penalize or favor any ingredient category — we test the outcome, not the philosophy.

Most pet food "standards" aren't

AAFCO sets minimums. "Organic" only covers farming. Most labels test for a handful of things — if they test at all. Here's how CBC compares.

What's tested AAFCO USDA Organic GFSI CBC
Full contaminant panel Partial 1,247 substances
Mycotoxins (full panel) ✓ 8 mycotoxins
Species-of-origin DNA testing ✓ PCR verified
Pentobarbital screening ✓ Required
Pathogen testing (per batch) ✓ Every batch
Nutritional label verification ✓ Full panel
Unannounced factory audits ✓ On-site
Quarterly retail spot-checks ✓ No notice

How a pet food earns the seal

A rigorous, transparent, five-phase process that takes 8–16 weeks from application to certification.

1

Application & Full Disclosure

Brand submits a complete dossier: every ingredient, every supplier, every processing aid, every co-packer. CBC reviews for completeness and identifies high-risk ingredients for intensified testing.

2

Independent Laboratory Testing

Multiple production batches are sent to one of our 9 partner labs (all ISO 17025 accredited). Full contaminant panel — 1,247 substances — using LC-MS/MS, GC-MS, ICP-MS, PCR, and ELISA. Nutritional verification via AOAC methods. Results go directly to CBC, never to the brand first.

3

Facility Audit

Unannounced on-site inspection of every production facility and co-packer. Auditors verify HACCP plans, sanitation logs, cold-chain records, allergen controls, and batch traceability. Photographs and findings become part of the public certification record.

4

Certification Decision & Registry Listing

If all six pillars are met, the product is awarded the CBC seal and listed in our public registry. Each certified product receives a unique ID. The full compliance report — including lab results, audit findings, and nutritional verification — is published.

5

Ongoing Surveillance

Every production batch must pass contaminant screening before release. Annual full-panel re-certification. Quarterly anonymous retail purchases tested against the full standard. Results published. A single batch failure triggers immediate public suspension and a consumer safety alert.

Veterinarians and food scientists, not marketers

Our certification criteria are developed and reviewed by an independent board of veterinary nutritionists, food safety scientists, toxicologists, and animal health researchers.

Questions pet owners ask

Straight answers about what our certification means — and what it doesn't.

The CBC seal guarantees that the pet food has been independently tested and found free — at parts-per-billion detection limits — of 1,247 contaminants including mycotoxins, heavy metals, pesticides, pentobarbital, melamine, acrylamide, and undeclared species. It guarantees the guaranteed analysis on the label has been independently verified. It guarantees the product was made in an audited, HACCP-verified facility with full batch traceability. And it guarantees the product is subject to per-batch release testing and quarterly unannounced retail spot-checks for as long as it carries the seal.
AAFCO sets minimum nutritional adequacy standards and labeling guidelines — it does not test products, inspect facilities, or screen for contaminants. AAFCO "compliance" simply means the label states the food meets AAFCO nutrient profiles. CBC independently verifies nutritional content, tests every batch for 1,247 contaminants, audits facilities, verifies ingredient sourcing through DNA testing, and publishes all results. AAFCO is a guideline; CBC is a guarantee backed by data.
Yes — but with additional scrutiny. For grain-free formulations, CBC requires verification of taurine levels, complete amino acid profiles, and cardiac-safe nutrient ratios in light of the FDA's investigation into diet-associated dilated cardiomyopathy (DCM). We don't penalize or favor any ingredient philosophy — we test the nutritional outcome. If a grain-free food meets all nutritional targets and passes all contaminant screens, it can earn the seal.
If a quarterly retail spot-check or per-batch release test detects any contaminant above our threshold, the product's certification is immediately suspended. The brand is notified, the product is removed from our public registry, and a consumer safety alert is posted on our website and distributed to our mailing list. The brand must identify the root cause, remediate, and pass three consecutive clean batch tests before the seal can be reinstated. Two failures in a 12-month period result in permanent delisting.
"Veterinarian recommended" is an unregulated marketing claim. It can mean anything from "one vet on payroll said yes" to "a panel of independent specialists reviewed it." There is no standard definition, no required disclosure of financial relationships, and no third-party verification. The CBC seal is the alternative: independent, data-driven, publicly documented, and free of financial conflicts. We publish the data so you can make your own informed decision.
Yes. CBC certifies the full range: dry kibble, wet/canned food, raw frozen, freeze-dried, air-dried, dehydrated, treats, dental chews, meal toppers, and nutritional supplements. Each category has specific additional testing requirements — for example, dental chews are tested for compressive strength to reduce choking risk, and supplements are tested for label-claim verification of active ingredient levels.
