UC Davis Biotech Program and the Cultivated Meat Consortium (CMC)
The UC Davis Biotech Program worked with campus research faculty to help launch the UC Davis Cultivated Meat Consortium (CMC) in the fall of 2019, and continues to lead the education and training efforts of the Integrative Center for Alternative Meats and Proteins (iCAMP) which was launched in January 2024. iCAMP has absorbed the Cultivated Meat Consortium as one of three main research focus areas, along with alternative meats and proteins derived from plants and fungi.
The Biotech Program has been engaging with industry partners working on cultivated meat since 2015, through seminars, graduate student internships, and on-going conversations about the latest bioprocessing technologies, research challenges, and workforce needs. Many of our Designated Emphasis in Biotechnology PhD alumni have pursued internships and careers in the cellular agriculture industry and we continue to help build out the education and training ecosystem to support this biotech sector. In addition to co-founding the CMC, UC Davis Biotech Program director, Dr. Jamison-McClung, represents the campus on the BioMADE Education and Workforce Development Committee and serves as an advisor for related groups working in this technology space (e.g., Good Food Institute, XPRIZE Feed the Next Billion).
Cultivated Meat and Alt Proteins Week - September 11-15, 2023
The UC Davis Cultivated Meat Consortium hosted an in-person Cultivated Meat and Alt Proteins Summit on September 11th at UC Davis. The event brought together members of academia, industry and government to discuss this growing research area and the outlook for commercialization in the US and abroad.
Sponsored by the UC Davis Biotechnology Program & the UC Davis Cultivated Meat Consortium, we held a virtual 4-day Cultivated Meat Short Course (fee-based) for students and professionals interested in learning more about cultivated meat research and on-going work at UC Davis. The research informing the short course was funded in part by NSF Growing Convergent Research award #2021132.

Public-Private Partnerships for DEB Graduate Trainee Support
Thanks to a gift from New Harvest to the UC Davis Biotechnology Program, graduate students enrolled in the Designated Emphasis in Biotechnology doctoral degree program and working in cellular agriculture, including alt proteins and cultivated meat, can apply for a DEB Research Award to support their work.
Bioprocessing, Food Technology and Entrepreneurship at UC Davis
UC Davis is a comprehensive research-intensive university that is highly ranked in key disciplines needed for the development of cultivated meat (e.g., stem cell biology and muscle physiology, animal science, plant science, food science, chemistry, chemical engineering, biomedical/tissue engineering and agricultural economics), alternative proteins, and many related food technology sectors. We are situated along the I-80 innovation corridor for biotechnology and biomanufacturing, with access to Bay Area investors and business expertise, which supports campus entrepreneurship and translational research in food tech and agriculture. UC has a long history of cooperative extension work to build the state's agricultural sectors and the UC Davis Graduate School of Management has a Food and Agriculture focused MBA track to further accelerate the growth of businesses in this ecosystem. A number of related campus institutes, educational units, and programs are listed below.

Federal Regulation of Cultivated Meat
On June 21, 2023, UPSIDE Foods and GOOD Meat received final approvals by the U.S. Department of Agriculture (USDA) for the sale of cell-cultivated chicken in the United States. This marked the first approvals of cultivated meat products in the U.S. and a turning point for the industry. The Food and Drug Administration (FDA) worked with the USDA to complete a joint review process that was initially outlined in March 2019. The announcement of these approvals was preceded by the successful conclusion of premarket consultation processes by the FDA (the "no questions" letters), USDA facility approvals, and USDA label approvals in spring 2023.
The partnership between the FDA and USDA in regulating cultivated meat is based on their traditional areas of oversight for food and feed production. These agencies hosted a webinar in 2020 to outline the rationale and plans for joint regulatory oversight: FDA and USDA Roles and Responsibilities for Cultured Animal Cell Human and Animal Food Products - YouTube.
Regulatory oversight for U.S. cultivated meat products occurs as follows:
- FDA oversees cell collection, cell banks, and cell growth and differentiation for all types of cultivated meat.
- FDA transfers oversight to the USDA at the stage of "harvesting" for cultured meat products that fall under the authority of the Federal Meat Inspection Act (FMIA) (cattle, sheep, swine, goats, and Siluriformes fish) or the Poultry Products Inspection Act (PPIA) (chicken, turkeys, duck, geese, guineas, ratites, and squab). USDA Food Safety and Inspection Service (FSIS) oversees downstream processing and labeling for these types of cultivated meat.
- All other types of animal cell cultures fall under the FDA's regulatory authority for processing and labeling via the Federal Food, Drug, and Cosmetic Act (FFDCA) and Public Health Service Act.
More details may be found on the FDA webpage Food Made with Cultured Animal Cells.
