Proposition 65 (the Safe Drinking Water and Toxic Enforcement Act of 1986) warning label requirements call for the label to identify the type of harm potentially posed by the substance(s) present in the product. The risk must be identified as cancer, reproductive harm, or both. The California government has a website where the type of harm for listed chemicals can be verified.
Exposure to lead, for instance, may lead to the risk of both cancer and reproductive harm under Proposition 65. Both risks should be listed, then, in the warning label text. Refer to California's online Proposition 65 resources for more information about warning label requirements, including wording, size, and imagery.
