This is a difficult question to answer, because it’s not easy to determine whether health problems that may not show up for decades are caused by exposure to radioactive contamination. A report released in February by the World Health Organization, which was based upon estimates of radiation exposure in the immediate area of the accident, concluded that it probably would cause "somewhat elevated" lifetime cancer rates among the local population. But figuring out the effect of years of exposure to lower levels of radioactive contamination leaking into the ocean is an even more complicated matter.
Because of the World Ocean currents, the various seafood that's caught off the US Pacific coast is more likely to contain radionuclides than the seafood in the Sea of Okhotsk, which is closer to Japan. It is these products that could possibly find their way to the tables of different countries' residents that pose the gravest danger (15)
As of right now there seems to be no immediate danger, but in the near future it is extremely possible things go south quickly
