Who regulates this? Well, both FDA and USDA. In FSIS directive 7800.1
- FDA and FSIS have agreed to jointly oversee the production of cell-cultured meat and poultry food products and to share information necessary to carry out their respective oversight responsibilities in establishments that harvest cells for cell-cultured meat or poultry food products.
- FDA has jurisdiction over the preharvest production phase of the animal cell culture technology process. During this phase, living cells are collected from species amenable to the Acts and stored. These living cells are later placed in a controlled environment, such as a bioreactor, and introduced to inputs (e.g., amino acids, glucose, and inorganic salts) and other factors that encourage their growth, multiplication, and differentiation into various cell types.
- Jurisdiction transfers to FSIS at harvest, i.e., when the cell-culture establishment commences the process of removing the cells from the controlled environment, thereby halting their ability to further grow, multiply, or differentiate into various cell types.
- FSIS also has jurisdiction over the postharvest processing and labeling of cell-cultured meat and poultry food products. Postharvest, establishments that produce cells for cell-cultured meat or poultry food products may distribute the raw harvested cells in commerce or process the harvested cells into finished products that contain ingredients, such as spices, flavorings, binders, or other ingredients. Some of these establishments may send harvested cells to other establishments for further processing, rather than processing these cells at the harvest facility.
- Ingredients, including processing aids, used in cell-cultured meat or poultry food products postharvest (including substances used preharvest that remain in the harvested cells) must be considered safe and suitable by FSIS and used in accordance with the intended use listed in 9 CFR 424.21(c) or FSIS Directive 7120.1, Safe and Suitable Ingredients Used in the Production of Meat, Poultry, and Egg Products.

USDA approves 1st ever 'cell-cultivated meat' for 2 American manufacturers
UPSIDE will cultivate and sell chicken grown from animal cells in bioreactors.
After years of research and rigorous testing, cell-cultivated meat will officially become part of the U.S. food system.
Emeryville, California-based manufacturer UPSIDE Foods, which gave ABC News a look inside its facilities earlier this year, and Good Meat a cultivated meat division of the plant-based egg substitute food technology company Eat Just, are the first U.S. Department of Agriculture-approved cell-cultivated chicken meat producer and has been fully approved by the U.S. government for commercial sales nationwide.
