Prop 65 Compliance for Peanut Butter
Download the Peanut Butter Prop 65 Compliance Project Brief (PDF)
Why This Matters
Peanut butter has its own Prop 65 chemistry — and an active NOV was filed against peanut-oil products in April 2026.
- Aflatoxin Is the #1 Risk: Aspergillus molds produce aflatoxin B1 on peanuts during warm/humid storage. Prop 65-listed as a carcinogen.
- Lead & Cadmium in Soil: Peanuts are legumes — deep roots concentrate soil metals. Variance by origin, field, and harvest year.
- Acrylamide: Now Enjoined: May 2, 2025 federal court permanently enjoined Prop 65 acrylamide food warnings. One vector closed — but testing still matters.
- Documentation Is Your Defense: Aflatoxin screens, storage data, lot testing, supplier audits — the only evidence that holds up in court.
Prop 65 Enforcement Trends (2024–2026)
Enforcement is accelerating — not slowing down.
- 3,100 NOVs in 2022
- 3,850 NOVs in 2023
- 4,450 NOVs in 2024
- 5,200 NOVs in 2025
- 5,800 NOVs projected for Q1 2026 run-rate
Key pressures: Food & Supplements account for ~64% of NOVs. 2026 settlements reached ~$98M. Aflatoxin is an active NOV target in peanut products.
Three Risk Vectors
Each vector has its own chemistry, source, and current regulatory status.
- Aflatoxin B1 (Active Enforcement): Aspergillus mold during warm/humid storage. FDA action level 20 ppb; Prop 65 NSRL far lower. April 2026 NOV confirmed live enforcement.
- Lead & Cadmium (Live Baseline): Soil bioaccumulation through peanut roots. MADL Pb 0.5 µg/day; Cd 4.1 µg/day. Variance by origin, field rotation, and harvest year.
- Acrylamide (Enjoined May 2025): Forms during roasting from asparagine + sugars. CalChamber v. Bonta permanent injunction — warnings now barred. Testing still valuable for documentation.
Business Impact of Non-Compliance
A Prop 65 action hits the balance sheet long before a verdict.
- 60-Day Notice of Violation: Plaintiff’s attorney files with the AG. Brand owner, private-label operator, and retailer all exposed.
- Settlement Exposure: Aflatoxin & heavy-metal settlements in food $25K–$200K+ per SKU. Mass retail reach multiplies SKUs.
- Mass Retail Delisting: Costco, Target, Walmart, Kroger require documented compliance. A single NOV can trigger buyer-initiated holds.
- Kids’ Formats Face AB 899: Kids’ peanut butter SKUs also fall under California AB 899 baby food testing & disclosure (effective Jan 2025).
Most companies settle — not because they’re guilty, but because their documentation is weak.

Core Technical Components
- Aflatoxin Testing (HPLC / LC-MS/MS): AOAC 991.31 or 2005.08 methods for aflatoxin B1, B2, G1, G2. ISO 17025 labs — per lot, finished product & raw material.
- Heavy Metal Testing (ICP-MS): Pb (MADL 0.5 µg/day), Cd (MADL 4.1 µg/day), As at ISO 17025 labs — documented per-serving exposure math.
- Storage & Mycotoxin Control: Temperature & humidity monitoring at every storage node. Mold risk is preventable; documentation stops recurrence.
- Origin & Crop-Year Tracking: Georgia, Texas, Virginia, Argentina, India, China — aflatoxin risk varies dramatically by origin and harvest year.
- AB 899 Kids’ Format Compliance: California’s AB 899 requires baby food testing & disclosure. Kids’ peanut butter SKUs inherit this parallel burden.
Supply-Chain Compliance Control
Prevent the issue upstream — before it reaches your label.
- Origin Attestation: Peanut origin & crop-year declarations from growers, shellers, and roasting processors.
- Blanching & Roasting Audit: Mycotoxin reduction verified at blanching step. Storage conditions tracked from field to plant.
- Lot Testing: Every incoming peanut lot tested for aflatoxins; finished butter tested for aflatoxin + metals.
- Supplier SCAR & Rejection: Out-of-spec lots diverted or rejected; supplier disqualification path documented.

Your Risk Profile
Every one of these factors increases your exposure — independently.
- Aflatoxin NOV (April 2026): Peanut-oil products cited for aflatoxin exposure via ingestion. Mycotoxin enforcement is live and on point for peanut butter.
- Heavy Metals Baseline: Peanuts as legumes concentrate soil Pb and Cd. MADL 0.5 µg/day (Pb) and 4.1 µg/day (Cd) stay fully enforceable.
- AB 899 Kids’ Formats: Kids’ peanut butter SKUs inherit California’s AB 899 baby food testing & disclosure requirements (effective Jan 2025).
- California: Most aggressive private-enforcement regime in the United States.
Your product is already in a high-risk category — even if you’ve done nothing wrong.
