Editor’s Note: This post has been updated to reflect 2018 revisions to the Prop 65 regulations, which for the first time allocated responsibility for compliance within the supply chain. These revisions place the primary responsibility for compliance on manufacturers, distributors

On June 3, 2019, the California Office of Administrative Law approved a regulation adopted by the California Environmental Office of Health Hazard Assessment (OEHHA) exempting chemicals in coffee from Prop 65’s warning requirement. The regulation, which has an effective date of October 1, 2019, provides:

Exposures to chemicals in coffee, listed on or before March 15, 2019 as known to the state to cause cancer, that are created by and inherent in the processes of roasting coffee beans or brewing coffee do not pose a significant risk of cancer.

While the adoption of the regulation would seem to end the ongoing controversy about whether Prop 65 warnings are required for acrylamide in coffee, and to be very good news for those who make and sell coffee, much dust remains to settle.

It’s been about six months since the new Prop 65 regulations allocated the primary responsibility for providing warnings to suppliers, manufacturers, distributors, and importers, while limiting retailers’ responsibility to limited, specified circumstances. Many wondered what impact these new regulations would have on the enforcement of Prop 65 against retailers. Six months in, the answer still isn’t clear.
