Food safety considerations in the advancement of cultured meat: Evaluating novel ingredients
Summary
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 has been and continues to be explored as a sustainable alternative to traditional livestock farming. Despite its potential, challenges such as high production costs and the lack of a clear regulatory framework hinder its large-scale, cost-effective adoption. As the technology for producing cultured meat advances, new ingredients are continually being developed to enhance yield and reduce costs. Food safety remains a critical consideration throughout these innovations. This commentary examines emerging ingredients in cultured meat research, including alternatives to Fetal Bovine Serum (FBS), scaffolding materials and cell lines. It highlights the importance of developing culture media formulations that use FBS substitutes and evaluates studies on plant proteins, insect proteins, and recycled animal waste from a food safety perspective. Additionally, the article addresses concerns related to microplastics in cultured meat, including their sources and potential impacts. Emphasizing the need for comprehensive safety assessments, this review calls for thorough evaluation of each novel ingredient and process involved in cultured meat production.
