Rice Recalled Over Gene Contamination
Tuesday, March 6, 2007
The Agriculture Department last night took the unusual step of insisting that U.S. farmers refrain from planting a popular variety of long-grain rice because preliminary tests showed that its seed stock may be contaminated with a variety of gene-altered rice not approved for marketing in the United States.
The announcement marks the third time in six months that U.S. rice has been found to be inexplicably contaminated with engineered traits, and it comes just weeks before the spring planting season.
Adding to the potential disruption, the variety of rice affected is one that many farmers had planned to switch to this spring to avoid a different contaminated strain.
The new problem involves Clearfield CL131 seed, produced by BASF of Germany and marketed by Horizon Ag of Memphis. In an after-hours posting on the USDA Web site, agency officials did not say which unexpected genetic trait had been found in the rice.
In August, Cheniere rice was found to be contaminated with an herbicide-resistance gene that had been under study in 2001 but was never approved or brought to market. The discovery continues to disrupt U.S. rice exports, even though the trait won speedy approval in December.
