From the Wall Street Journal:

The U.S. Department of Agriculture is considering imposing restrictions for the first time on where and how a genetically modified crop may be grown, in a move that could eventually affect a wide swath of the farm industry.

The USDA is considering approving the use of genetically modified alfalfa, a forage crop grown to feed livestock, but with limitations aimed at assuring that gene-altered crops don't contaminate fields of non-biotech crops, according to USDA officials. The new limitations could be particularly important to organic farmers, whose sales depend on assuring consumers that their products aren't artificially engineered, among other things.
