Known officially as The California Safe Drinking Water and Toxic Enforcement Act of 1986, California Proposition 65 reaches far beyond state boundaries and has potential regulatory implications for almost any company that manufactures, imports, and / or sells products containing listed chemicals in the state. California Prop 65 prohibits the sale of a product in California that knowingly and intentionally exposes an individual to a California Office of Environmental Health Hazard Assessment (OEHHA) listed chemical without a specific stated warning. For many food and supplement companies, the risk of opportunistic litigation based on California Prop 65 drives the need to monitor updates, new amendments and enforcement of the law.

Prop 65 Background

California Proposition 65, also known by the shortened name Prop 65, is not a ban on products or ingredients. The law is intended to inform consumers in California about exposure to a list of chemicals exceeding a defined level in products for sale, including product packaging. The regulation mandates a warning label for exposure to chemicals at a level that could cause cancer, birth defects or other reproductive harm. Guidance for upper limits (“Safe Harbor Level”) on chemicals is based on expected daily exposure. If no Safe Harbor Level exists for a chemical, the product containing a listed chemical must include a warning, unless the exposure level can be proven to not pose a significant risk of causing harm.

With the size of the California economy and the interconnected U.S. supply chain, the state law effectively reaches other states and U.S. importers. More recently, the Prop 65 requirements impact online and catalog sales, which have increased significantly during the global pandemic.

Know Your Suppliers

All companies need to proactively evaluate and document Prop 65 risks. Enforcement occurs primarily through civil litigation, resulting in specialized legal firms profiting from a company’s ignorance of the law’s extent. Even the threat of publicity from a lawsuit can cause targeted companies to settle a case.
At each point of manufacturing and distribution—supplier, manufacturer, packager, importer or distributor—regulatory teams should ask about Prop 65 compliance. The main point of responsibility is at the manufacturer, but a retailer can also be obligated for introducing a chemical at point-of-sale.

What’s New with Prop 65

The OEHHA issues notices regarding amendments to the California Code of Regulations Title 27, Article 6, covering “Clear and Reasonable Warnings”. Recently the OEHHA requested public comments on proposed amendments that would modify the content and methods for providing “short-form” warnings. The short form was originally intended for products with restricted label space.

The proposed rule would modify the existing short-form warning provisions to:

• Only allow use of the short-form warning on products with five square inches or less of label space.
• Eliminate use of short-form warnings for products sold via the Internet and catalogs.
• Clarify how short-form warnings can be used for food products.
• Require the name of at least one chemical be included in the short-form warning.

Bottomline: Know Your Business and Risk

As an advisor with more than 20 years of regulatory compliance experience in food and food ingredients, my guidance for business best practice on Prop 65 is to be proactive, maintain supply chain knowledge, and understand risk. Regulatory or legal staff, or consultant teams specializing in Prop 65, should regularly monitor for additions to the chemical list and rulemaking changes to the far-reaching law.
