US genetically modified rice inquiry draws blank
A lengthy US investigation has been unable to determine the exact causes of two cases of rice contamination by unregistered genetically modified rice lines. The USDA's Animal and Plant Health Inspection Service (APHIS) began its investigation in 2006 after Bayer CropScience reported that its glufosinate-tolerant LLRICE601 had been detected in long-grain rice (Agrow No 502, p 12). The inquiry was expanded this year following the discovery of Bayer's LLRICE604 in BASF's Clearfield CL131 rice (Agrow No 517, p 16). The APHIS will take no action against Bayer because it was "unable to make any definitive determinations that could have resulted in enforcement action".
