Folks:
This series of articles should be read and we should all be aware of the risks of the FDA, EPA, and USDA acting like ostriches with their heads buried in the sand.  The current actions clearly shout:  "If we do not look for problems, we won't find them and have to respond in any way." (?sound familiar--like asbestos, etc.?) 

Scientists now know that nanomaterials can damage or destroy DNA or chromosomes and have been linked to "the big killers of man" (like cancer, heart disease, strokes, endocrine disruption, etc.---to say nothing about what will happen in vitro to any fetus and the chance of live birth or a child with full physical and mental abilities!).
 
This is about the scariest series of articles I have ever read and it includes pharmaceuticals, disposal of drugs, and other waste streams as well as imported foods dipped in nanomaterials to increase shelf life of produce and its potential impact on human health.  The US is ignoring nanomaterials, but Canada and the EU are not.

Amid Nanotech's Dazzling Promise, Health Risks Grow March 24 2010 
 
-- For almost two years, molecular biologist Bénédicte Trouiller doused the 
drinking water of scores of lab mice with nano-titanium dioxide, the most common 
nanomaterial used in consumer products today. She knew that earlier studies 
conducted in test tubes and petri dishes had shown the same particle could cause 
disease. But her tests at a lab at UCLA's School of Public Health were in vivo 
-- conducted in living organisms -- and thus regarded by some scientists as more 
relevant in assessing potential human harm. Halfway through, Trouiller became 
alarmed: Consuming the nano-titanium dioxide was damaging or destroying the 
animals' DNA and chromosomes. The biological havoc continued as she repeated the 
studies again and again. It was a significant finding: The degrees of DNA damage 
and genetic instability that the 32-year-old investigator documented can be 
"linked to all the big killers of man, namely cancer, heart disease, 
neurological disease and aging," says Professor Robert Schiestl, a genetic 
toxicologist who ran the lab at UCLA's School of Public Health where Trouiller 
did her research.
