That is an interesting article Brian. I tried to find corroborating eveidence regarding fallout over the USA and while articles can be found, there's a notable lack of official detailed assessment. Either the amounts of radiation entering the US food chain are insignificant or the government is lying to the people.
Here's another article:

Excerpts:
EPA discontinued its Fukushima radiation monitoring efforts, and FDA says there is no danger to our food or seafood and therefore testing is not necessary. There have been no calls since the accident for heightened nuclear safety inspections or to upgrade or decommission aging nuclear power plants in the U.S.
Yet, in limited testing conducted by states and independent labs since the accident, radioactive iodine and cesium—both toxic to human health—have appeared at elevated levels in milk and vegetables produced in California. Radiation has also been detected in milk sold in Arizona, Arkansas, Hawaii, Vermont and Washington since the accident

The presence of iodine 131, with a short half-life of eight days, in the new milk samples indicates that even now, nuclear reactions are occurring at the crippled Japanese plant, bringing fresh fallout on a daily basis to Asia, North America and around the northern hemisphere.
