The west coast got a good dose of radiation from Fukushima. Hot particles have shown up in air filters from Seattle and even in air filters from Boston. Cesium has been found in soil samples from California. According to the video below some areas received more radiation than others from rainout events. It may be that some farms received a significant amount of fallout.
Also, large amounts of radiation have gone into the sea from Fukushima. We should be testing seafood.
I don't know about you, but I would prefer my food without radiation.
