The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced on June 11, 2021, that it intends to list tetrahydrofuran, 2-ethylhexyl acrylate, methyl acrylate, and trimethylolpropane triacrylate (technical grade) as carcinogens under Proposition 65. Also known as the Safe Drinking Water and Toxic Enforcement Act of 1986, Proposition 65 prohibits knowingly exposing any individual to a listed chemical without first providing a “clear and reasonable warning” to such individual. 

The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) announced on March 19, 2021 that it intends to list perfluorooctanoic acid (PFOA) as a chemical known to the state to cause cancer under Proposition 65 based on the

The California Office of Environmental Health Hazard Assessment (OEHHA) relisted bisphenol A (BPA) as a reproductive toxicant (developmental endpoint) under Proposition 65. The listing became effective December 18, 2020.

California’s Office of Environmental Health Hazard Assessment (OEHHA) proposes to amend the Safe Drinking Water and Toxic Enforcement Act of 1986 (Prop 65) by adopting Section 25505, “Exposures to Listed Chemicals in Cooked or Heat Processed Foods.” The proposed amendment establishes maximum concentration levels for listed chemicals in foods that are produced by cooking or heat processing that are deemed by OEHHA to be the lowest levels currently feasible.

In November 2018, California’s Office of Environmental Health Hazard Assessment (OEHHA) proposed amending Article 6, Section 25600.2 of Title 27 of the California Code of Regulations.  This provision speaks to the responsibility to provide consumer product exposure warnings for chemicals listed under California’s Proposition 65. The amendment was proposed to clarify how a product manufacturer—and other parties that may receive the products before they reach the retailer—can pass warning information along the supply chain and ultimately to retailers.
