Beer and Genetically Modified Crops

From CNN:

Anheuser-Busch Cos., the nation's No. 1 buyer of rice as well as its largest brewer, says it won't buy rice from Missouri if genetically-modified medicinal crops are allowed to be grown in the state.

The St. Louis-based beer giant is the latest company to express concern over plans by Ventria Biosciences to grow 200 acres of rice engineered to produce human proteins capable of making medicine.

The company says it is concerned about possible contamination.
