In previous decades, the safety of many probiotics available to consumers was based on a long history of safe consumption in humans. However, the range of probiotics is expanding to include non-traditional probiotic strains that might offer health benefits but are not commonly found in food sources and have no history of safe use.A group of industry and government scientists convened under the auspices of the United States Pharmacopeia's Probiotic Expert Panel recently set out to review current approaches to assessing the safety of probiotics from a scientific perspective, while also looking at what regulators currently require. The newly published paper summarizes scientific frameworks for assessing the safety of probiotics used in foods and dietary supplements, including the importance of comprehensive genomic characterization. The paper questions the value of animal testing for probiotics intended for human use. Further, the paper considers emerging technologies for safety testing as well as how manufacturing practices play an important role in the safety of the final product.Recognizing that regulatory approaches to probiotic safety vary greatly around the world, the paper focuses on scientifically meaningful approaches for safety assessment. Risk tiers for probiotics are identified, based on available information on history of safe use. For strains of species recognized by authoritative bodies as having a sufficient history of safe use, and for which their genomes show no genes of concern, no additional testing is proposed. But if genes of concern are present or a history of safe use is lacking, additional testing is warranted. Safety of genetically modified probiotics or probiotics used as drugs was not addressed in this paper.Dr. Mary Ellen Sanders, the Executive Science Officer for the International Scientific Association for Probiotics and Prebiotics (ISAPP), and a co-author of the paper, commented, "The current situation, with different countries having different criteria for showing safety of the same probiotic strain, is not ideal. This paper calls for a more harmonized regulatory approach to probiotic safety, based on sound scientific principles."Sanders says that while probiotics in foods and supplements are used widely and have a good safety record, establishing safety of innovative strains may require more extensive testing prior to marketing.Amy Roe, Principal Toxicologist, Product Safety & Regulatory Affairs, The Procter & Gamble Company, led the writing effort. She says, "We hope that this review, which includes the use of modern technologies and approaches, will provide helpful recommendations for completing a comprehensive safety assessment of a probiotic."ISAPP is the international non-profit organization that works to advance the science of probiotics, prebiotics and related substances, such as synbiotics, postbiotics and fermented foods. Founded in 2002, ISAPP brings together global leading scientific experts and has shifted the paradigm for how probiotics and prebiotics are studied and understood.USP is an independent, scientific non-profit organization whose purpose is to improve global health through public standards and related programs that help ensure the quality, safety and benefit of medicines, dietary supplements and foods.( With inputs from ANI )Disclaimer: This post has been auto-published from an agency feed without any modifications to the text and has not been reviewed by an editor
