From the BBC:
"But it (Tepco) stressed in a news conference on Monday that if people ate fish and seaweed caught near the plant every day for a year, their radiation exposure would still be just 0.6 millisieverts. Normal background radiation levels are on the order of 2 millisieverts per year."
So not really ideal but hardly a huge deal in terms of public health risk. Most of the Iodine-131 in the water will have decayed in a couple of weeks so won't be a problem anyway. The only long term concern would be if there were significant ceasium concentrations in the water (although even then at these levels it's unlikely to provide any sort of risk).
