The French Agency for Food, Environmental and Occupational Health and Safety (ANSES) published on March 10, 2015, an Opinion concerning exposure to silver nanoparticles that “stresses the research that has been carried out to examine the potential health and environmental effects of silver nanoparticles but notes that this is still insufficient to allow the health risks to be assessed.” ANSES states that, based on the conclusions of its April 2014 Opinion on the risks associated with manufactured nanomaterials, it recommends limiting the marketing of products containing silver nanoparticles to applications whose advantages have been clearly demonstrated. ANSES recommends encouraging research concerning physico-chemical characterization, exposure assessment, toxicology and ecotoxicology, assessment of antibacterial effectiveness, and bacterial resistance, as well as enhancing the traceability of data and consumer information on products containing silver nanoparticles. ANSES recommends that the use of silver nanoparticles (production, processing, utilization) be limited to applications whose advantages have been clearly demonstrated, and whose benefits to human health outweigh the risks for the environment.
