Effective September 27, 2013, the Office of Environmental Health Hazard Assessment (OEHHA) is adding chloramphenicol sodium succinate (CAS No. 982-57-0) to the list of chemicals known to the State to cause cancer for purposes of Proposition 651.

The listing of chloramphenicol sodium succinate is based on a formal requirement by a state or federal agency that the chemical be identified or labeled as causing cancer2 as provided under the Act.  Chloramphenicol sodium succinate has been identified or labeled to communicate a risk of cancer in accordance with formal requirements by the U.S. Food and Drug Administration.  Regulations governing the listing of chemicals under the “formally required to be labeled or identified” mechanism are published in Title 27, California Code of Regulations, section 25902.

The documentation supporting OEHHA’s determination that the criteria for administrative listing have been satisfied for chloramphenicol sodium succinate is included in the Notice of Intent to List A Chemical by the “Formally Required to Be Labeled or Identified” Mechanism:  Chloramphenicol Sodium Succinate, published in the August 2, 2013 issue of the California Regulatory Notice Register (Register 2013, No. 31-Z).  No public comments were received.
