FDA to industry: Please call us if you put nanomaterials in food

Earlier this summer, the U.S. Food and Drug Administration (FDA) advised the food industry what a manufacturer should do if it puts nanomaterials in food: Please call us. The human health effects of ingesting nanomaterials are not well understood, but a few food manufacturers claim to include nanomaterials in their products. The FDA’s advice could have been worse: Don’t call us.
