Iowa’s Attorney General and 15 of his counterparts are urging the maker of StarLink corn to take new action to protect the interests of farmers, grain elevator operators and consumers. That genetically modified corn has crept into the food chain even though it’s not approved for human consumption. Iowa Assistant Attorney General Steve Reno says a letter to Aventis outlines previous promises and asks that new steps be taken. He says grain handling has been a problem as corn is rejected. He says there needs to be more done to reroute the corn to approved sites.Reno says the payment for the buyback process also needs speeding up.Iowa produced more StarLink than any other state. The letter was also signed by attorneys general from Missouri, Minnesota, Illinois, Nebraska, both Dakotas and nine other states.
