Food tests in usa

Any one with any links for recent food tests for radiation please post.I personally can't find any news story or any testing news it baffles my mind how few and far in-between food tests have been it is astounding(as well as lakes river water ect) . brawns team testing which has been welcomed and is awesome-but is so far from comprehensive .why not test our food our fish our beef .has there not been the highest level of nuclear accident blowing and raining on us for a month .now I feel like a minority doomsdayer because I care. I am not sure what to make of this except to go on with life accepting low level cesium in my food chain. I guess if there not testing it means it's there.draw your own logical conclusions I guess.
