USDA's Food Safety and Inspection Service (FSIS) issued a September 16, 2021 final response to Harvard Law School Animal Law and Policy Clinic's petition regarding labeling for “cell-based” meat and poultry products.
In it's June 9, 2020 petition, the clinic called for a labeling approach that would not require new standards of identity for cell-based meats and poultry products or prohibit them from being referred to by common or usual meat or poultry terms specified by current codified standards of identity.
The agency says it's September 3, 2021 advance notice of proposed rulemaking (ANPR) pertaining to the labeling of meat and poultry products comprised of or containing cultured cells derived from animals is a result of the petition and "high degree of public interest." Comments in response to the ANPR can be submitted to the agency through November 2, 2021. The docket number is FSIS–2020–0036.
