With the 4th of July coming up, 100% grass fed and grass finished beef is our risk mitigating choice for the grill.
We will cover this subject in more detail when we release our analysis of the nearly $2000 dollars worth of professional radiological laboratory tests we have had performed on the pre and post Fukushima beef samples. (Many thanks to those who stepped up and helped us fund this effort by using the DONATE button on our webpage; so far we have raised approximately $439 of donations to off set the lab costs ).
Pending the release of the tests performed on our own farmer's grass fed and well watered beef, we suggest reading these two Cold War era studies of the Cesium uptake of grass fed and grain fed beef.

The transfer coefficient of 137Cs from feed to meat was about twice as great for a high grain ration as for rations high in roughage or about 3.0% as compared to 1.5%.
Metabolism of Radioactive Cesium and Potassium by Dairy Cattle as Influenced by High and Low Forage Diets
The data also showed a less efficient transfer to milk with diets consisting predominantly of hay as compared with rations containing a high percentage of grain.
