Global Insights into Cultured Meat: Uncovering Production Processes, Potential Hazards, Regulatory Frameworks, and Key Challenges—A Scoping Review
Summary
This review examines the production process and potential health hazards of lab-grown cultured meat, including contamination risks from microplastics in growth media and packaging materials. The findings suggest that while cultured meat may reduce some environmental impacts of traditional farming, new food safety risks including microplastic contamination need careful regulation.
This scoping review aims to understand the cell-based meat production process, including the regulations, potential hazards, and critical points of this production. This review includes studies on cultured meat production processes, health hazards, and regulatory guidelines, excluding those without hazard analysis, incomplete texts, or studies published before 2013. The search was performed in eight electronic databases (MEDLINE, Web of Science, Embase, Cochrane Library, Scopus, LILACS, and Google Scholar) using MeSH terms and adaptations for each database. The search for local studies on regulations and guideline documents was complemented by a manual search on the websites of governments and regulatory agencies from different regions (e.g., FDA, FAO, EFSA, USDA, Health Canada, EC, EU, ANVISA/Brazil, MAPA/Brazil, FSANZ, and SFA). This step involved reading full texts to confirm eligibility and extract key data, including author, year, country, study design, objectives, results, cultured meat protocols, health hazards, and hazard control measures, followed by data analysis. A comprehensive search of the databases yielded 1185 studies and 46 regulatory or guidance documents. After removing duplicate studies and applying eligibility criteria to titles, abstracts and full texts, 35 studies and 45 regulatory or guidance documents were included. The cultured meat production protocols are well-established, highlighting potential hazards and critical control points. Although guidance documents and regulations are limited, they are expanding globally. The development and commercialization of cultured meat require clear, and up-to-date regulations and supervision, which are being studied and formulated by regulatory agencies worldwide. Cultured meat production presents some potential hazards (chemical, biological, and physical) that require food safety considerations: (i) genetic stability of cells/cell lines; (ii) microbiological hazards related to cell lines; (iii) exposure to substances used in the production process; (iv) toxicity and allergenicity of the product or its component for the population; (v) post-harvest microbiological contamination; (vi) chemical contamination/residue levels; and (vii) nutritional aspects/risks. Currently, no standardized testing approach exists for cultured meat. However, effective hazard and safety assessment strategies, such as HACCP combined with best practices, should be implemented throughout the production process.

Food safety considerations in the advancement of cultured meat: Evaluating novel ingredients
This commentary on cultured meat (lab-grown meat) includes a brief but notable section on microplastics as an emerging food safety concern for the technology, noting that plastic scaffolding materials and other production inputs could introduce microplastics into the final product. The paper also addresses cell culture media, fetal bovine serum alternatives, and regulatory gaps more broadly. While not primarily a microplastics study, it raises the underexplored question of whether cultured meat could become a new dietary route of microplastic exposure.
Cultured meat in the European Union: Legislative context and food safety issues
Researchers review the regulatory and food safety landscape for cultured meat — animal protein grown from cells in a lab rather than slaughtered animals — within the European Union's precautionary approval framework. While cultured meat could reduce agriculture's enormous carbon footprint and help feed a projected 9–11 billion people by 2050, concerns about production safety, texture, nutrition, and consumer acceptance still need to be resolved.
Can Cultured Meat Be an Alternative to Farm Animal Production for a Sustainable and Healthier Lifestyle?
This review examines whether cultured meat, grown from cells in a bioreactor rather than raised on farms, could serve as a more sustainable alternative to conventional animal agriculture. Researchers found potential benefits including reduced land use and pollution, but noted that the energy required for cultured meat production could be higher due to replacing biological functions with technological processes.
Investigating the Impact of Microplastics on Fish Muscle Cell Proliferation and Differentiation: Enhancing Food Safety in Cultivated Meat Production
Researchers exposed Atlantic mackerel muscle cells to polyethylene microspheres at concentrations representative of environmental contamination and found that microplastics significantly impaired cell attachment and proliferation, particularly at 10 µg/mL. The findings matter for the growing cultivated meat industry, which sources cells from marine species already exposed to microplastics, raising food safety questions.
Enhancing food safety and cultivated meat production: exploring the impact of microplastics on fish muscle cell proliferation and differentiation
Researchers investigated how microplastic contamination affects fish muscle cells used in cultivated meat production. They found that polystyrene microplastics impaired the ability of fish cells to grow and develop into muscle tissue, even at relatively low concentrations. The findings raise concerns about microplastic interference in both lab-grown seafood production and the safety of sourcing cells from marine organisms already exposed to plastic pollution.
