FDA Confronts Nanotechnology: Agency believes it has the authority it needs to regulate nanomaterials [1] - Chemical & Engineering News, USA
As products made with engineered nanomaterials find their way into the marketplace in greater numbers, the federal agency most responsible for ensuring the safety of these products will be the Food & Drug Administration. From cosmetics to food packaging, and from drug components to implantable devices, FDA is where nanomaterials will have to get approval.
But is FDA ready for this responsibility? Does it even have the legal authority to make judgments on nanomaterials? And are the resources and expertise available to make these assessments?

Foodborne pathogens cause approximately 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths in the United States each year. Three pathogens, Salmonella, Listeria, and Toxoplasma, are responsible for 1,500 deaths each year.

It could have broad appeal to the food industry, food safety inspection agencies, government agencies overseeing food safety, and researchers focused on safety and biosecurity research.
