In October 2000, Jerry Rosman, an Iowa farmer, noticed a problem with his hogs. During breeding, the female sows exhibited all signs of pregnancy, yet when the time came to deliver nothing happened, a phenomenon called “pseudopregnancy.” Over the next year, the breeding rates in Rosman’s sow herd plummeted 80 percent. Rosman eventually traced the problem back to his feed, which was genetically modified Bt corn. Laboratory tests revealed that the corn contained high levels of Fusarium, a fungal pathogen that can produce mycotoxins, which can enter the food chain and negatively affect human and animal health.

Rosman wasn’t the only farmer with the problem. More than twenty farmers in Iowa and surrounding states reported the same breeding problems. At least five farmers switched to non-GMO corn feed and the problem disappeared.

Glyphosate seen as cause for health problems

Iowa veterinarian Art Dunham, who works with dairy and beef cows and hogs, says he has seen animal health problems from GM feed since Rosman reported his problems almost 15 years ago. Dunham believes that glyphosate, the main ingredient in Roundup herbicide, which is used extensively with GM soy, corn, and other crops, is a major culprit. “The most obvious problems with glyphosate-GMO has been with the Fusarium mycotoxins noticed at first in the early 2000s and worse in the cold damp years since,” he says.
