State, federal investigators check fish, food for radiation

By June Watanabe


Question: Is the state Department of Health or the federal government spot-testing fish sold here for radiation exposure due to the meltdown of the Fukushima nuclear plant following the March tsunami/earthquake in Japan — in particular, fish known to migrate to Japanese waters? How do we know that the fish we are consuming is safe?

Question: What is the best way to test food from Japan for radiation?

Answer: You don’t need to test the food from Japan because state and federal agencies are testing it for you.

The U.S. Food and Drug Administration, the U.S. Department of Agriculture and the National Oceanic and Atmospheric Administration say they have been working with U.S. Customs and Border Protection “to assure that our food supply, both domestic and imported, is safe to eat.”

As of Nov. 2, the FDA said, its investigators had performed more than 27,267 field examinations for radionuclides (radioactive contaminants). They had tested 1,123 samples, including 173 on seafood or seafood products. Only one sample had a detectable level of radionuclides “of concern,” but it was below the established “Derived Intervention Level” and “posed no public health concern,” the FDA said.

The FDA also said it does “not anticipate any public health effect on seafood safety” for a number of reasons, including little or no harvesting of fish taking place around the reactor area; water’s properties as both a shield and diluent, or diluting agent; and the rapid decaying of some radioactive isotopes.

The FDA and Customs officials said they screen all imported food from Japan for radiation, including fish harvested in Japan.

Less than 4 percent of food imported into the United States comes from Japan.

Japan has not exported beef products to the U.S. for nearly a year and is not eligible to export any poultry or processed egg products, the USDA said.

In addition, the Japanese government has restricted sale or export of certain products, including tea leaves from several affected prefectures; certain produce from the Fukushima Prefecture; and milk from the Fukushima and Ibaraki Prefectures.

It would be “correct” to say that consumers do not need to be concerned about radiation problems with food from Japan, because of federal and state monitoring, said Lynn Nakasone, administrator of the state Department of Health’s Environmental Health Services Division.

In addition to the federal oversight of food, Nakasone said the Health Department continues to conduct normal, routine testing of radionuclides in the air, drinking water, precipitation and milk as part of the Environmental Protection Agency’s RadNet program.

“Testing results indicate levels are back to normal ambient levels,” Nakasone said.

The Health Department also periodically conducts shoreline monitoring, “in which inspectors literally walk along a specific shoreline and using radiation detection equipment to measure the sand and anything that has washed ashore for any measurable increase in radiation levels.”

 No spikes in radiation levels have been seen, she said.

“Collectively, these results will be considered ‘background’ and compared to the Japan debris field scheduled to reach Hawaii in the next couple of years.”

Even if the officers are not present every day, their occasional monitoring makes drivers without passengers think twice about taking a chance. —– L. Harbottle
