Acetaminophen: Under Consideration for Listing by the Carcinogen Identification Committee

The Office of Environmental Health Hazard Assessment (OEHHA) is not rescheduling the Carcinogen Identification Committee (CIC) at this time due to the ongoing challenges posed by COVID-19.  OEHHA planned to announce a new meeting date for spring 2020; however, given the escalating concern over the COVID-19 public health emergency, OEHHA has decided not to reschedule the meeting until after the emergency has passed.  When OEHHA reschedules the CIC meeting it will provide notice on its website and via listserv.

The Office of Environmental Health Hazard Assessment (OEHHA) is announcing the postponement of the Carcinogen Identification Committee (CIC) meeting scheduled for December 5, 2019, and the opening of an additional public comment period on the potential listing by the CIC of acetaminophen as a carcinogen under Proposition 65. OEHHA is postponing the meeting to provide the public additional time to submit relevant scientific information concerning the potential listing.  The public comment period will commence on November 29, 2019 and end on January 27, 2020.  All comments received will be provided to the committee for their consideration. The CIC meeting will be rescheduled after the close of the public comment period.

Hazard Identification Materials, including the OEHHA document “Evidence on the Carcinogenicity of Acetaminophen,” additional references identified by OEHHA and public comments, may be found at www.oehha.ca.gov/Proposition-65.  We encourage interested parties to submit comments in electronic form, rather than in paper form.  Comments can be submitted electronically through OEHHA’s website at https://oehha.ca.gov/comments.  Comments submitted in paper form should be mailed, faxed, or delivered in person to the addresses below:
