UK FSA and FSS publish guidance for cell-cultivated foods; a review of analytical methods for the FSA finds that no single test is sufficient to identify such products
On 30 September 2026 the Food Standards Agency (FSA) and Food Standards Scotland published a further package of guidance for businesses developing cell-cultivated products — on regulatory authorisation and on the assessment of growth media components and toxicology. The FSA also points to its published review of analytical methods for such products.
- The authorisation guidance explains how the regulated products framework applies to cell-cultivated products, including how to handle changes to an authorised product; the growth media guidance covers the assessment of safety hazards linked to growth media components. This is the third batch from the Sandbox Programme, which runs from February 2025 to February 2027.
- The review of analytical methods, published by the FSA on 1 September 2026, concludes that no single method — DNA-based, protein-based or chemical profiling — can reliably authenticate all such products. The most promising approach is a “weight of evidence” combining several techniques (genomics, proteomics, chromatography, spectroscopy, structural analysis, digital tools).
- The authors point to the risk of cell-cultivated products being diluted with cheaper conventional meat; current species identification methods will not necessarily detect this type of fraud. The main barrier is the lack of validated methods and well-characterised reference materials.
- Recommendations include early adoption of metrological principles, harmonised testing standards, inter-laboratory studies, curated datasets and reference materials, and combining rapid, inexpensive screening (e.g. ELISA, spectroscopy) with confirmatory tests. In order of priority, further work is suggested on weight-of-evidence approaches, digital barcoding, epigenetics and microbial profiling.
