Japan’s Consumer Affairs Agency (CAA) has released draft guidelines outlining the safety requirements that manufacturers of cultivated meat and seafood must meet before bringing products to market, presented at a May 28 meeting of the Food Sanitation Standards Council’s Subcommittee on Novel Foods.
The document covers four areas: cell properties and characterization, manufacturing and quality management, the safety of cultivation inputs, and overall product assessment.
Cell sourcing and contamination
Producers must confirm that the animal cells used in cultivation are free from pathogens, disease, and naturally occurring toxins relevant to the source species. Cells from sick animals are excluded under existing Japanese food hygiene law. Companies must also verify cell identity using genetic testing and demonstrate that cells have not undergone unintended changes during the process of establishing a stable cell line.
Manufacturers must show that key production conditions, including temperature, nutrient levels, and acidity, are reliably controlled and reproducible across batches. Contamination prevention measures aligned with HACCP standards must cover the entire production process, and quality oversight must be kept structurally separate from production management within a company.
Cultivation inputs and residues
All media components, growth factors and scaffold materials must be assessed for safety. Anything not intended to remain in the final product must be shown to be effectively removed. Where animal-derived ingredients are used, additional checks for pathogens are required. Known allergens must be identified, with appropriate labeling considered where residues may reach consumers.
The draft also states that standard processing steps and normal digestion are expected to address concerns around cell proliferation in the final product, though manufacturers will still need to supply supporting data.
Japan’s regulatory framework for cultivated foods has been in development for some time, with the Consumer Affairs Agency’s Food Safety Standards Council, Subcommittee on Newly Developed Foods, working toward formal guidelines. Last August, the subcommittee had identified and organized potential hazards, but the process of assessing those risks remained ongoing, with safety checkpoints the next step before guidelines could be consolidated. The May 28 session indicates that work is now progressing into that phase, though the CAA has indicated that scope and structure remain under discussion.
