The U.S. Senate wisely voted down a bad amendment to the farm bill last week, meaning that consumers won’t see their food bills skyrocket for no worthwhile reason.

So that’s good news. Yet this is Washington, D.C., where the threat of harmful legislation remains alive and well–and we the people must remain on guard.

As the House of Representatives begins to consider its own version of the farm bill, it too must oppose efforts by anti-biotech activists to encourage a patchwork of confusing regulations that would make food much more expensive without improving it even a tiny bit.

In the United States and around the world, we’re fighting a war over food. Most people don’t even know that it’s going on, but it affects all of us. The conflict pits ordinary consumers and farmers like you and me against radical activists and professional protestors.

We all want a plentiful supply of wholesome and safe food at a reasonable price. Their scheme is to devastate modern means of crop production for the sake of an anti-scientific agenda that will make it harder for families to feed themselves.

The war has many fronts, from international agencies to state capitols. The latest assault took place in the U.S. Senate. Senator Bernie Sanders of Vermont — an “independent” who calls himself a socialistoffered an amendment to the farm bill.

On the face of it, the Sanders amendment sounded reasonable: It would have granted states the right to establish their own rules for labeling food that contains biotech ingredients. In the last year, legislators in 19 states have offered three dozen bills on this matter, according to Packaging Digest. This November, California voters will weigh a ballot initiative to require labels on food that may contain GM ingredients.

Yet think about where state-by-state labeling could lead: 50 states with 50 different sets of rules about what information must appear on consumer products. Special-interest groups would have a field day. A dairy state might stop companies from printing the saturated-fat content on cartons of ice cream. Georgia could require peaches from South Carolina to carry labels urging people not to buy them. Just imagine what the busybodies in New York City might try to do. The mayor already is on a crusade to ban soda pop.

Before long, food companies would have to package the same food in a variety of ways. For most of us, Coke cans and Pepsi bottles probably would continue to look much as they do now. In New York, however, perhaps they’d carry skull-and-crossbones images.

That may sound extreme, but something like it is already going on: A group called “Label It Yourself” encourages activists to print their own warning stickers, visit grocery stores, and slap them on items that may contain biotech ingredients.
