Nanotechnology: No One Is Evaluating the Risks!

The use of nanotechnology in food production is becoming more commonplace in many countries, yet the risks and benefits are not being adequately investigated.

| April/May 2012

The use of nanotechnology in food production is becoming more commonplace in many countries, including the United States. At a November 2011 workshop in London, however, an independent advisory panel to the United Kingdom’s Food Standards Agency demanded public debate and regulation of nanomaterials in foods (read Use of Nano-Materials in Foods Must Be Openly Debated, Warn Experts).

Nanotechnology allows the manipulation of materials on the scale of atoms, measured in nanometers (one billionth of a meter). The resulting nanoparticles are now being used in everything from appliances to cosmetics to clothing, yet the public knows little about them or the risks they may pose to human health.

To many food technologists, nanoparticles hold the potential to improve food safety, quality, and shelf life. Many companies are already using them in agriculture, food processing, food packaging, and supplements, yet often the food companies themselves don’t even know whether they’re using nano-based materials or not!

To help companies learn about the topic, the California-based nonprofit environmental and social responsibility organization As You Sow has issued a Sourcing Framework for Food and Food Packaging Products Containing Nanomaterials, in which it says:

“The risks and benefits of this emerging technology are still being discovered, yet the development, use and manufacturing of nanomaterials are being conducted with little transparency and inadequate regulatory oversight. This is particularly concerning to the food industry where human exposure is virtually guaranteed. The food industry is reported to be extensively researching and developing the use of nanomaterials; however, there is little known about the extent to which nanomaterials are used in food products, processing or packaging.”

As You Sow is conducting a survey of nanotechnology’s use in food, with plans to share results in mid-2012. Meanwhile, findNano is a free Apple app that lists products containing nanotech.

To bad that we have so many risks, we can not continue in the same manner!

It's a very relevant post. Thanks for posting.

I guess that there are many more risks than benefits, maybe you should stop!

More than 150 workshops, great deals from more than 200 exhibitors, off-stage demos, hands-on workshops, and great food!
