I don't think the U.S should be in a panic state over any radiation that might reach us. Sure, none would be ideal, but the small amounts that could get here are certainly not going to be a threat to the food and water supply and our lives - IMO. I've had enough x-rays in my lifetime for dozens of people, and I'm not glowing yet, and I'm certain I won't die from radiation poisoning. The U.S. needs to be a lot more worried about the pesticides that we use - the amounts that get into the soil and water and food that we eat. I'm a lot more concerned about that, than the possibility of somewhat elevated radiation levels from the Japan disaster.
