Milk-Whitening Nanotech Enters US Food Supply Without FDA Oversight

from rawstory.com: The Project on Emerging Nanotechnologies (PEN) revealed earlier this week that there are over 1,600 nanotechnology-based products on the market today — and that the United States Food and Drug Administration (FDA) lacks the authority to regulate them.

As Mother Jones reported, some of these nanotechnological innovations — which refer to particles less than 100 nanometers wide, or approximately 1/800th the diameter of a strand of human hair — are likely harmless, such as embedded silver particles in athletic socks and underwear. According to SmartSilver Anti-Odor Nanotechnology Underwear, the microscopic silver particles are “strongly antibacterial to a wide range of pathogens, absorb sweat, and by killing bacteria help eliminate unpleasant foot odor.”

However, the PEN database also includes 96 nanotechnology-infused items currently stocked on grocery store shelves, and none of these items listed their nanotechnology among their ingredients. Included on the list are Dannon Greek Plain Yogurt, Hershey’s Bliss Dark Chocolate, Kraft’s American Cheese Singles, and Rice Dream Rice Drink, all of which contain nanoparticles of titanium dioxide.
