Corn-Fed Controversy


| September/October 2002


An Iowa farmer is charging that genetically modified corn has rendered many of his sows infertile. As Tim Block reports in the Iowa Farm Bureau Spokesman (May 4, 2002), some 80 percent of Jerry Rosman's sows were unable to conceive after being fed a diet of genetically engineered Bt corn; similar cases have been reported by other farmers in his county. Rosman changed the sows' diet and the problem vanished. 'If I had been the only one, I'd say it's a fluke, but here we've got four others who experienced the same signs, symptoms, and outcome,' Rosman says, 'and I don't think there's just five of us out here.'
