What Are the Prop 65 Violation Numbers for 2024? (And Why It Matters to Your Business)

Introduction: Understanding Prop 65 Enforcement Activity

California Proposition 65 remains one of the most actively enforced consumer protection laws in the United States. Businesses selling food, dietary supplements, cosmetics, or consumer products into California must understand enforcement trends to properly assess compliance risk.

This article reviews estimated Prop 65 violation activity for 2024, explains what those numbers represent, and outlines how businesses can reduce exposure to enforcement actions. :contentReference[oaicite:0]{index=0}

Estimated Prop 65 Violations in 2024

While the State of California does not publish a single consolidated annual total, enforcement activity is typically measured using 60-Day Notices of Violation (NOVs).

Estimated 2024 Enforcement Activity:

• Approximately 4,000 to 5,000 or more Notices of Violation (NOVs)

This estimate is based on publicly available enforcement data and trend reporting.

What Counts as a Prop 65 Violation?

Most reported violations refer to 60-Day Notices of Violation (NOVs), which are legal notices issued prior to filing a lawsuit.

Key Characteristics of NOVs:

• Issued before formal litigation
• Allege exposure to listed chemicals without proper warning
• Filed by private enforcers, law firms, or advocacy groups
• Publicly recorded and searchable

NOVs are the primary metric used to measure annual enforcement activity.

Settlements and Litigation Outcomes

Only a portion of NOVs result in formal settlements or litigation outcomes.

Example:

• Approximately 797 settlements recorded in 2023

This demonstrates a significant difference between the number of notices issued and the number of cases ultimately resolved.

Key Insight:

• Notices of Violation: Thousands per year
• Settlements: Hundreds per year

Trend Analysis: Increasing Enforcement Activity

• 2023: Approximately 4,000+ notices
• 2024: Approximately 4,000–5,000+ notices (estimated)
• 2025: Already exceeding 5,000 notices

Monthly enforcement data further illustrates the volume of activity. In some periods, more than 600 notices have been issued within a single month.

This trend indicates continued growth in Prop 65 enforcement activity.

Common Chemicals Driving Violations

A significant portion of Prop 65 enforcement actions are associated with a limited number of chemicals:

• Lead (Pb) – food products, supplements, ceramics
• Cadmium – cocoa products, chocolate, jewelry
• Phthalates (DEHP, DBP) – plastics and packaging
• PFAS – textiles and food contact materials
• Acrylamide – coffee and processed foods

These chemicals are frequently cited due to their prevalence in common product categories.

Why These Numbers Matter for Your Business

The volume of enforcement activity demonstrates that thousands of businesses are targeted each year.

Even if your product:

• Includes a warning label
• Uses compliant ingredients
• Is manufactured by a third party

Your business may still be exposed if compliance is not supported by proper documentation and monitoring systems.

The Real Risk: It Begins Before Litigation

Prop 65 risk does not begin with a lawsuit—it begins when a 60-day notice is issued.

This often results in:

• Rapid settlement pressure
• Legal and consulting costs
• Marketplace disruptions (Amazon, Walmart, and others)
• Brand and reputational impact

How to Reduce Prop 65 Risk

Businesses can reduce risk by implementing structured compliance systems that include:

• Chemical risk assessments
• Supplier disclosure documentation
• ISO 17025 laboratory testing verification
• Safe harbor threshold evaluations (NSRL and MADL)
• Warning justification documentation
• Ongoing batch or lot monitoring
