Food industry ‘too secretive’ over nanotechnology. BBC News. January 08, 2010. The food industry has been criticised for being secretive about its use of nanotechnology by the UK’s House of Lords Science and Technology Committee.Lord Krebs, chairman of the inquiry, said the industry "wants to keep a low profile" to avoid controversy.While there were no clear dangers, he said, there were "gaps in knowledge".In its report Nanotechnologies and Food, the committee suggests a public register of foods or packaging that make use of nanotechnology.
