Eight months after being collected for testing, 15 two-year-old bluefin tuna collected last August off San Diego were found to have levels of radiation originating from last year’s Japanese nuclear disaster. Depending on who was doing the reporting, there was either 10 times more radiation than ever found before in tuna or just a three percent increase in radiation found in the past. Both the Japanese and U.S. governments said the amount of radiation is still so low as to not create a health risk, and humans consume far more radioactive material from other types of foods. Yellowfin tuna tested did not have levels that were different from past testing, but they do not travel across the Pacific. Albacore were not tested. Two questions not answered in the reporting on this issue: Why did it take eight months to report this to the public? And at what point do insignificant amounts of radioactive material in our diets become a health threat?
