That pesky senate of ours!
They're trying to take away states' rights to have more stringent food labelling laws than what the federal government requires. This attempt would also take away the rights of local municipalities to pass laws preventing GMOs and RGBH. You can read more here. The National Uniformity for Food Act has already passed the house; we need to keep it from passing the Senate.
According to the Organic Consumers Association: "The "National Uniformity for Food Act," lowers the bar on food safety by overturning state food safety laws that are not "identical" to federal law. Hundreds of state laws and regulations are at risk, including those governing the safety of milk, fish, and shellfish. The bill is being pushed by large supermarket chains and food manufacturers, spearheaded by the powerful Grocery Manufacturers of America."
The OCA page linked to above has suggestions about things you can do to try to prevent the act's passage. Chief among them? Call your senator, or send an email. There's a pre-written email for the lazy ones among us on that OTA page. If you're up to calling your senator, which is much easier and less intimidating than it sounds, you can find your state's senators here. Their phone numbers are listed, and really you just call, wait for an answer, and then tell the lucky person on the other end that you're calling to strongly encourage your senator to oppose the National Uniformity for Food Act. Tell them why, if you feel like elaborating. If you are a voting constituent, be sure to mention that fact and that there are many, many people who agree with you who aren't calling but who are out there talking about it.
Really, it's EASY to call your senators. It's easier to send an email, but calling takes about two minutes, three max, and phone calls are given much more weight when the senators and their staffs are trying to figure out how we all feel about upcoming votes. If you care about food labeling and local municipalities and states being able to do things like vote to ban GMOs, I highly recommend taking a few minutes to make your opinion known. It's worth it.
