The Proposition 65 warning requirement for exposures to BPA, listed as a reproductive toxicant, is effective on May 11, 2016. California's Office of Environmental Health Hazard Assessment (OEHHA) has issued two proposed regulations -- an emergency regulation for exposure to BPA through ingestion, which permits temporary point of sale warning signage for canned and bottled food and beverages, and a proposed regulation which sets a safe harbor level of 3 mcg/day for dermal absorption of BPA from solid materials.
