Addressing the safety of new food sources and production systems

Abstract

New food sources and production systems (NFPS) are garnering much attention, driven by international trade, changing consumer preferences, potential sustainability benefits, and innovations in climate‐resilient food production systems. However, NFPS can introduce new challenges for food safety agencies and food manufacturers. Most food safety hazards linked to new foods have been identified in traditional foods. However, there can be some food safety challenges that are unique to new foods. New food ingredients, inputs, and processes can introduce unexpected contaminants. To realize the full potential of NFPS, there is a need for stakeholders from governments, the food industry, and the research community to collectively work to address and communicate the safety of NFPS products. This review outlines known food safety hazards associated with select NFPS products on the market, namely, plant‐derived proteins, seaweeds, jellyfish, insects, microbial proteins, as well as foods derived from cell‐based food production, precision fermentation, vertical farming, and 3D food printing. We identify common elements in emerging NFPS regulatory frameworks in various countries/regions. Furthermore, we highlight current efforts in harmonization of terminologies, use of recent scientific tools to fill in food safety knowledge gaps, and international multi‐stakeholder collaborations to tackle safety challenges. Although there cannot be a one‐size‐fits‐all approach when it comes to the regulatory oversight for ensuring the safety of NFPS, there is a need to develop consensus‐based structured protocols or workflows among stakeholders to facilitate comprehensive, robust, and internationally harmonized approaches. These efforts increase consumers’ confidence in the safety of new foods and contribute toward fair practices in the international trade of such foods.
