As others have said, the Tuna, most likely caught off NE Japan (80% of tuna sold in the U.S. is caught there, in any case), is highly radioactive...not just a little if caught in those waters. Why? Tuna is at the top of the food chain and marine ecosystems are extreme bioaccumulators, including or especially of radionuclides. Only plants are able to resist internalized radionuclides and then, only very miniscul e amounts, not the amounts we're seeing in fallout worldwide since March, 2011. Fukushima Dai Ichi and Japan have had at three least absolutely uncontained nuclear power plant melted down reactor cores, "corium", fissioning perpetually, leaking fallout into both the ocean and the air, for one year and ten months. Remember that the lives affected by Chernobyl were from only 7 days of uncontained fissioning of nuclear power plant corium, which of late is heating up, spalling and probably close, itself, to bursting into flames, as may have happened just recently at either the common spent fuel pool or the Fukushima Dai Ichi reactor 4 spent fuel pool (R4 SPF). So, $1.8M for mercury and diverse radionuclide contaminated tuna? Brilliant!

oprah has somethin similar to this under her dress. not sure that I'd pay 1.8 million for it though.

This whole deal smells a bit fishy to me.
