"If you haven’t heard of nanosilver, you’re definitely not alone. But that doesn’t mean these tiny silver particles intended to kill bacteria aren’t ending up in your food. There are now over 400 consumer products [PDF] on the market made with nanosilver. These include many intended for use with food, among them cutting boards, cutlery, pans, storage containers, espresso machines, water filters, baby bottles, and refrigerators.
The U.S. Environmental Protection Agency (EPA) considers nanosilver a pesticide and requires products that contain–or are treated with this germ-killer–to be registered with and approved for use by the agency. But most of the nanosilver products now on the market have not been reviewed, let alone approved by the EPA.
Just a few weeks ago, in an attempt to close this loophole, the Center for Food Safety, the Center for Environmental Health, Clean Production Action, the Institute for Agriculture and Trade Policy, and other nonprofits filed suit against the EPA for failing to respond to their 2008 petition [PDF], asking the agency to regulate all products containing nanosilver as pesticides."
