Jeffrey Smith, in his book Seeds of Deception, recounts the stories of the cows: (Read the story of the geese here.)
"In 1998, Howard Vlieger harvested both natural corn and a genetically modified Bt variety on his farm in Maurice, Iowa. Curious about how his cows would react to the pesticide-producing Bt corn, he filled one side of his sixteen-foot trough with the Bt and dumped natural corn on the other side. Normally, his cows would eat as much corn as was available, never leaving leftovers. But when he let twenty-five of them into the pen, they all congregated on the side of the trough with the natural corn. When it was gone, they nibbled a bit on the Bt, but quickly changed their minds and walked away."
"A couple of years later, Vlieger joined a room full of farmers in Ames, Iowa to hear presidential candidate Al Gore. Troubled by Gore's unquestioning acceptance of GM foods, Vlieger asked Gore to support a recently introduced bill in Congress requiring that GM foods be labeled. Gore replied that scientists said there is no difference between GM and non-GM foods. Vlieger said he respectfully disagreed and described how his cows refused to eat the GM corn. He added, "My cows are smarter than those scientists were." The room erupted in applause. Gore asked if any other farmers noticed a difference in the way their animals responded to GM food. About twelve to fifteen hands went up."
"If a field contained GM and non-GM maize, cattle would always eat the non-GM first."Story 3
- Gale Lush, Nebraska
"A neighbor had been growing Pioneer Bt corn. When the cattle were turned out onto the stalks they just wouldn't eat them."
- Gary Smith, Montana
"While my cows show a preference for open-pollinated corn over the hybrid varieties, they both beat Bt-corn hands down."
- Tim Eisenbeis, South Dakota
"According to a 1999 Acres USA article, cattle even broke through a fence and walked through a field of Roundup Ready corn to get to a non-GM variety that they ate. The cows left the GM corn untouched."
"Bill Lashmett watched as two or three cows were let into a feeding area at a time. The first trough they came to contained fifty pounds of shelled Bt corn. The cows sniffed it, withdrew, and walked over to the next trough, which contained fifty pounds of natural shelled corn. The cows finished it off. When they were gone and released from the pen, the next group came in and did the same thing. Lashmett said the same experiment was conducted on about six or seven farms in Northwest Iowa, in 1998 and again in 1999. Identical trials with hogs yielded the same results, also for two years in a row."
The FDA does not require labels on GM foods because they claim, "bioengineering does not make a food inherently different from conventionally produced food.":
"Consumer: Why doesn't FDA require companies to tell consumers on the label that a food is bioengineered?"Somebody needs to inform the cows and hogs.
"FDA: We are not aware of any information that foods developed through genetic engineering differ as a class in quality, safety, or any other attribute from foods developed through conventional means. That's why there has been no requirement to add a special label saying that they are bioengineered."
