Cell-cultivated foods: New developments in the recent UK FSA guidance

Cell cultivated food, sometimes refferred as "lab grown meat", now follow a new guidance developing and producing cell-cultivated products.

The UK Food Standards Agency (FSA), in collaboration with Food Standards Scotland (FSS), has released four new guidance documents to support companies developing cell-cultivated foods. Published as part of the Cell-Cultivated Products Sandbox Programme, these documents aim to provide greater regulatory clarity to help businesses bring innovative products to market.

Together, the guidance covers everything from hygienic production requirements and scientific expectations for safety assessments to practical advice for preparing Novel Food applications and conducting taste trials. Rather than introducing new legislation, these documents clarify how existing regulatory requirements apply to this emerging sector and provide practical recommendations to help companies navigate the market authorisation process more effectively.

Why has the FSA published these new guidance documents?

Cell-cultivated foods are one of the fastest-growing areas of food innovation, but they also present unique regulatory challenges. Through its Sandbox Programme, the FSA is working closely with industry to develop a common understanding of how existing food regulations apply to these products.

The newly published guidance aims to provide businesses with greater certainty on regulatory expectations, helping developers prepare more robust applications while supporting efficient safety assessments.

Which guidance documents have been published?

The FSA has released four complementary guidance documents addressing different stages of product development and regulatory compliance.

The first guidance focuses on food business hygiene requirements, explaining how existing hygiene rules apply to the production of cell-cultivated foods. It clarifies key aspects such as the regulatory status of production facilities, the application of hygiene principles throughout the manufacturing process and the responsibilities of food business operators.

The second document provides supplementary guidance on identity, production and microbiology, outlining the scientific information expected when characterising cell lines, describing manufacturing processes and demonstrating microbiological safety. Its objective is to help companies prepare more comprehensive dossiers that facilitate the regulatory assessment.

The third guidance, Improving your cell-cultivated product application, offers practical recommendations for preparing high-quality Novel Food applications. Drawing on the FSA’s experience with submitted dossiers, it highlights common deficiencies including incomplete product characterisation, insufficient production process descriptions and poorly structured documentation, and explains how these issues can be avoided.

Finally, the guidance on Novel Food taste trials clarifies the conditions under which taste trials of unauthorised novel foods may be conducted for research and development purposes. It explains the responsibilities of businesses, the importance of risk assessments and ethical oversight, and the role of local authorities in ensuring that these activities remain within the scope of legitimate R&D.

What do these publications mean for the food businesses?

Although the guidance does not introduce new legal requirements, it could represent an important milestone for companies developing cell-cultivated foods. By providing clearer scientific and regulatory expectations, the FSA is helping businesses better understand the evidence required to support product safety and prepare stronger market authorisation applications.

For developers, this increased clarity has the potential to reduce avoidable requests for additional information, improve dossier quality and support a more predictable regulatory pathway as the sector continues to evolve.

Whether you are developing a cell-cultivated product or another Novel Food, understanding regulatory expectations early in development is essential for a successful market authorization strategy.
