FDA Scientists Develop Technique for Probiotic Purity
FDA scientists have provided “proof-of-concept” for a technique that identifies the presence of potentially harmful contaminants in probiotics. “The technique eliminates a product’s beneficial bacteria and allows any potentially harmful contaminants in the product to grow unimpeded, allowing detection of potentially harmful contaminants using standard laboratory methods,” an agency notice says.
The scientists developed and used recombinant phage lysins as reagents for improved purity assays for probiotics. Their FDA study forms the basis of a strategy for further development of lysins as tools and reagents to improve probiotic purity testing, which could help advance product development, the agency notice says.
