High-fives all around for a major win in the global fight against illegal, unregulated, and unreported (IUU) fishing! In a successful international effort by U.S., Canada, China, and Japan, a Chinese fishing vessel was apprehended this past May for illegally fishing with large-scale high seas drift nets in the Northern Pacific Ocean.
[A quick FYI – The United Nations banned the use of large-scale (over 2.5 km long) drift nets in 1991 due to incredibly high rates of bycatch]
A Canadian CP-140 maritime patrol aircraft first sighted the 191-foot Yin Yuan on May 22nd in the Northern Pacific Ocean. The aircraft crew, which also included Japanese spotters, relayed its sighting to the U.S. Coast Guard cutter Morgenthau, reporting that the vessel had equipment on board associated with high seas drift net fishing.
On May 27, the Morgenthau caught up with the Yin Yuan nearly 625 miles east of Tokyo, and boarded the vessel along with officers from the China Coast Guard’s Fisheries Law Enforcement Command. The Yin Yuan’s captain admitted to throwing 3.3 km of driftnet as well as other equipment overboard before the Morgenthau had caught up with his vessel.
The Coast Guard found between 900 and 1200 lbs of salmon on board and identified the vessel to be in violation of several fisheries laws, including: fishing with illegal gear, failing to maintain sufficient catch data, and fishing without any kind of license, permit, or official authorization. The Morgenthau escorted the Yin Yuan to the East China Sea, where it turned the vessel over to Chinese authorities on June 3, 2014.
The U.S., Canada, Japan, and China are part of a multilateral enforcement effort to detect and deter IUU fishing in the Northern Pacific, including high seas drift net fishing. The story of how the Yin Yuan was apprehended is a great reminder that IUU fishing is a global problem that demands global solutions and international coordination.
With its recent ratification of the Port State Measures Agreement and establishment of a national task force to combat IUU fishing, the U.S. has stepped up as a global leader in the IUU arena. We still have a long ways to go in eliminating IUU fishing, but the U.S. is making steady progress in combatting illegal fishing on the high seas, monitoring our own state waters, working on a global front to protect fisheries resources and ocean health. Continued due diligence by seafood businesses, including verifying the legality and traceability of products, will help this effort maintain its momentum.

FishWise is continuing to follow the status of the radioactive plume of seawater from the Fukushima Daiichi Nuclear Power Plant in Japan and its potential to contaminate Pacific seafood. Based on the best scientific information available, consuming Pacific seafood is still safe. U.S. state and federal agencies continue to deliver the message that the levels of Fukushima-derived radiation are unlikely to cause significant harm to the public and the risks are small when compared to other things that threaten public health (e.g. smoking, air pollution, obesity, etc.).
Who is testing for radiation?
The U.S. Food and Drug Administration (FDA) is the primary federal agency responsible for testing food imported from Japan for radiation. The FDA routinely tests for radionuclide contamination and monitors information and data from foreign governments and international organizations, including the Japanese government’s food sample testing program, the import sample testing programs of nations geographically close to Japan, and the Fukushima-related activities of international organizations like the International Atomic Energy Agency (IAEA) (FDA 2014). In light of the information collected from these sources, in March 2014, the FDA released this update on its website:
To date, FDA has no evidence that radionuclides from the Fukushima incident are present in the U.S. food supply at levels that would pose a public health concern. This is true for both FDA-regulated food products imported from Japan and U.S. domestic food products, including seafood caught off the coast of the United States. Consequently, FDA is not advising consumers to alter their consumption of specific foods imported from Japan or domestically produced foods, including seafood. FDA continues to closely monitor the situation at and around the Fukushima Dai-ichi facility, as it has since the start of the incident and will coordinate with other Federal and state agencies as necessary, standing ready to take action if needed, to ensure the safety of food in the U.S. marketplace. (FDA 2014)
Import Alert #99-33 instructs FDA field personnel to detain shipments from Japan if the food is likely to contain radionuclide contamination. The FDA’s Import Alert #99-33 website contains a long list of seafood species from the Fukushima prefecture that the Japanese Prime Minister has ordered to be restricted from distribution into the export market, including:
Alaska Pollock, ayu, barfin flounder, black cow-tongue, black rockfish, braddblotched rockfish, brown hakeling, salmon (landlocked), common carp, conger eel, crucian carp, fat greenling, flathead, flathead flounder, fox jacopever, goldeye rockfish, gurnard, halfbeak, black porgy, dace, eel, sandlance, seabass, littlemouth flounder, long shanny, marbled flounder, nibe croaker, northern sea urchin, ocellate spot skate, olive flounder, pacific cod, panther puffer, poacher, red tongue sole, ridged-eye flounder, rockfish (sebastes cheni), sea raven, spotted halibut, slime flounder, spotted halibut, starspotted smooth-hound, starry flounder, stone flounder, surfperch, venus clam, whitespotted char. (FDA 2014)
The U.S. Environmental Protection Agency (EPA) is monitoring levels of radiation in air and precipitation through its RadNet program (EPA 2013). Ocean monitoring of Fukushima radiation has received much less attention from U.S. government agencies. Neither the U.S. government nor the state of California has an ongoing testing program for Fukushima-derived radiation off of the California coast (California Coastal Commission 2014).
However, there is a volunteer radiation-monitoring project underway led by scientists from Woods Hole Oceanographic Institute in Massachusetts. Our Radioactive Ocean is a program in which scientists and citizens can send samples of Pacific Ocean water to be analyzed for Fukushima-derived radiation at Woods Hole. To date, The Our Radioactive Ocean website was updated on June 2, 2014 with this statement:
So far, none of the seawater samples taken from the Pacific Coast have contained any trace of radiation from Fukushima. They have contained the same levels of radiation that were evident in the Pacific Ocean before the Fukushima accident. These levels of cesium-137 measured at all sites are between 1 and 2 Bequerels per cubic meter, and are from the 1960s atmospheric nuclear weapons testing programs. The lack of cesium-134, which only has a two-year half-life for radioactive decay, indicates that none of the Fukushima contaminants have reached the West Coast sampling sites. Therefore, continued support for monitoring is needed as the cesium isotopes are expected to reach the coast in 2014 and levels are predicted to increase over the coming 2-3 years.

Kelp Watch 2014 is a project to determine possible radionuclide contamination of kelp forest ecosystems along the California coast by testing kelp samples in multiple locations along the west coast (Kelp Watch 2014). One of the main goals of the project is to soothe public anxiety about the severity of the radiation plume’s impact on coastal ecosystems. The researchers leading the project are confident that the radiation concentration found in kelp samples that will bioaccumulate in the food web that humans are part of will be so low as to pose no harm to human health (Samuel 2014).
Has the radiation from Fukushima arrived on the West Coast?
Since the disaster occurred in April 2011, a radioactive plume of contaminated seawater has been carried towards the west coast of North America by ocean currents. As of April 30, 2014, no Fukushima-derived cesium has been detected in seawater off the coasts of California, Oregon, or Washington (California Coastal Commission 2014). The leading edge of the radioactive plume appears to have recently reached Vancouver Island off of Canada, and could possibly reach California next year, although coastal upwelling could hold the plume at bay for several years (Rossi et al 2013). The peak concentration of Fukushima-derived radionuclides is anticipated to reach California between 2016 and 2019 and then gradually decline over the following decades (California Coastal Commission 2014).
Should we be worried?
The answer that scientists studying the issue have come to is no. Due to the rapid dilution of the radioactive seawater in the vast Pacific Ocean, the concentration of radionuclides from Fukushima is expected to be only slightly above pre-accident levels, and far below naturally occurring radioactive elements in the ocean (Buesseler 2014). Even the highest estimated levels of radioactivity are more than 400 times lower than levels of naturally-occurring radiation and represent only a tiny increase in total radioactivity above pre-accident levels (California Coastal Commission 2014).
Evidence for this can be found to the north of Hawaii and off the coast of British Columbia, where the low levels of cesium detected indicate that the level of exposure along the west coast will be low and marine organisms such as fish are extremely unlikely to accumulate dangerous quantities of radioactivity (California Coastal Commission 2014).
Is Pacific seafood contaminated?
Along the west coast of the United States, low levels of cesium radioisotopes from Fukushima have been found in Pacific bluefin (Madigan et al 2012) and albacore tunas (Neville et al 2014). In 2011, Madigan et al detected very low levels of Fukushima-derived cesium in highly migratory Pacific Bluefin tuna, which the researchers determined had accumulated in the tissue of the fish during the juvenile phase of their life cycles in the western Pacific (Madigan et al 2012). A follow-up study in 2012 found that radiocesium levels in Pacific bluefin had decreased by more than 50%, indicating that the concentration of radioactivity in the ocean from Fukushima is rapidly decreasing (Madigan et al 2013).
Using the same dataset as Madigan et al, Fisher et al concluded that a subsistence fisherman consuming only Pacific Bluefin tuna in amounts five times greater than the average total seafood consumption in the US would receive 0.1% more radiation than the normal annual radiation dose humans receive (Fisher et al 2013).
Some bottom dwelling fish such as flounder tested very close to the reactor off Japan have been found to have levels of radiation above Japanese regulatory limits, so eating those fish is not recommended. However, due to closures of fisheries in the areas near Fukushima and Japan’s strict limits for radiation in seafood, it is extremely unlikely those fish could make it to US markets (Buesseler 2014).
Short background on radiation in the ocean
The vast majority of radioactive particles in the ocean are there as a result of the weathering of rocks and the erosion of continental crust (Buesseler 2014). Until the Fukushima plant meltdown, the primary anthropogenic source of radiation was from fallout from nuclear weapons testing in the 1950’s and 1960’s and from Chernobyl fallout, to a lesser extent. Cesium-137 is the main radionuclide of concern following the Fukushima disaster due to its relatively long half-life (over 30 years) and potential to affect human health through bioaccumulation. Cesium-134 has a short half-life (two years) and therefore decays quickly, making it less of a threat. Both isotopes of cesium are highly soluble in ocean water, meaning that a radioactive plume of these particles quickly dilutes as a result of ocean current and mixing processes (Buesseler 2014).
Conclusion and Recommendations
FishWise maintains the same conclusion and set of recommendations from our last update in December 2013. There is no question that there are major concerns regarding the effects of radiation from the damaged Fukushima Daiichi Nuclear Power Plant on human health and the environment. However, the key results from these peer-reviewed studies and from the government tests have been misrepresented in the media and have led to the concern that seafood in the Pacific is contaminated from the Fukushima plant and unsafe to eat. While Japanese subsistence fishers may need to take caution, people in the U.S. eating seafood from the eastern Pacific do not need to spend too much time worrying. Based on the scientific information available, consuming Pacific seafood is safe. We will update our research on this situation as new information becomes available.

Update on the Fukushima Nuclear Power Plant: What you need to know about radiation in Pacific Seafood
In March 2011, the Fukushima Daiichi nuclear power plant in Japan suffered major damage when it was hit by a powerful 9.0 earthquake and subsequent tsunami, resulting in the largest nuclear disaster since Chernobyl. On July 22, 2013, over two years later, the Tokyo Electric Power Company (Tepco) acknowledged that radioactive water from the plant continues to leak into the Pacific ocean at a rate of nearly 300 tons per day, causing global concern about contaminated seafood. There are concerns about the local effects of the radiation to Japanese seafood, but radiation from Fukushima rapidly dilutes in concentration as currents carry it across the Pacific, making the risk of human health impacts from contamination along the West Coast extremely low. Scientists predict that waters contaminated with radionuclides from Fukushima will reach the northwestern American coast by early 2014 (Rossi et al 2013). However, this should not be cause for alarm. On December 5, 2013, the chairwoman of the U.S. Nuclear Regulatory Commission announced that the highest amount of radiation that will reach the U.S. coast is 100 times lower than the drinking water standard.
There are several different radionuclides that are entering the ocean near the leaking power plant. Until the Fukushima plant meltdown, the primary source of cesium-137 to the ocean was from weapons testing in the 1960s and from Chernobyl fallout, to a lesser extent (Cs-134 was also released but has long since decayed). Because both cesium isotopes (Cs-134 and Cs-137) rapidly disperse in seawater and Cs-134 has a short half-life, any Cs-134 detected in fish samples can be traced back to the Fukushima power plant (Madigan et al 2013). Strontium-90 is another radionuclide leaking from the plant in small amounts. As of November 2013, the levels of strontium-90 found in fish near the nuclear power plant were far lower than that of cesium isotopes.
Scientists from around the world are testing organisms near the power plant for levels of radiation to determine if there is a risk to human health. A study conducted by scientists from Woods Hole Oceanographic Institution tested fish for radiation in waters near the power plant and found that the median concentration of Cesium-137 was about 150 times below the Japanese legal limit (Buesseler et al 2012). The researchers’ conclusion from the study was that, even within 30 kilometers of the leaking nuclear power plant, seafood is safe for human consumption. Radiation risks from Cesium-134 and -137 to humans consuming seafood are well below those from radionuclides that occur naturally in seawater, which include potassium, polonium, and even uranium (Buesseler et al 2012).
Along the west coast of the United States, low levels of cesium radioisotopes from Fukushima have been found in Pacific bluefin (Madigan et al. 2012) and albacore tunas. Again, this should not cause alarm to seafood lovers, as the levels of those radioisotopes were far lower than naturally occurring radioisotopes (Fisher et al 2013). In both studies, the researchers involved were more excited about the ability to use radiation from Fukushima to learn about the seasonal migration patterns of tuna than the radioactivity of the fish. Scientists cannot say that there is no health risk from eating Pacific seafood with traces of radiation from Fukushima, but they do agree that the risk is extremely low. Personal assessment of the risks associated with consuming fish that potentially carry Fukushima-derived radiation should be evaluated in the context that almost all foods, including produce and fish, carry (and have always carried) radioactive material from natural sources in the earth.
The U.S. National Oceanographic and Atmospheric Administration (NOAA) is responsible for testing marine debris from Japan for radiation contamination. The plume of water from Fukushima is predicted to reach the northwestern American coast by early 2014 (Rossi et al 2013). As of November 2013, detectable levels of radiation from Fukushima have not been found in any marine debris that has made it to the west coast.
The Food and Drug Administration (FDA), Environmental Protection Agency (EPA), and the National Oceanographic and Atmospheric Administration in United States are monitoring radiation from Fukushima. As of June 20, 2012, the FDA has tested 1,313 samples for radionuclide contamination. One sample has been found to have detectable levels of radiation from the nuclear power plant, but it was still well below the safety threshold.
There is no question that there are major concerns regarding the effects of radiation from the damaged Fukushima Daiichi Nuclear Power Plant on human health and the environment. However, the key results from these studies and from the government tests have been misrepresented in the media and have led to the concern that seafood in the Pacific is contaminated from the Fukushima plant and unsafe to eat. While Japanese subsistence fishers may need to take caution, people eating seafood from the eastern Pacific do not need to spend too much time worrying. Based on the scientific information available, consuming Pacific seafood is safe. We will update our research on this situation as new information becomes available.

While environmental sustainability is now a common topic for discussion during seafood procurement, less emphasis is placed on the social & human rights aspects of seafood supply chains. This paradigm is starting to shift out of necessity, in terms of both risk management and opportunities for story telling & promotion.
Along with the moral atrocities of human rights abuses, sales of even the most environmentally sustainable product could decrease significantly if human rights violations in the product’s supply chain were discovered and reported to consumers. Some companies are ahead of this curve, having found that highlighting the social benefits to regions and communities help consumers connect with the source of a product. For example, ThisFish allows consumers to email the fisherman directly, I Love Blue Sea dedicates an entire page to introducing you to their fishermen, Pacifical promotes its investment in Pacific communities by increasing local processing employment opportunities, and ANOVA details its social commitments in its Sustainability Report.
Unfortunately, fishing related industries—most notably shrimp peeling and processing operations in Thailand and “Flag of Convenience” (FoC) fishing vessels throughout South East Asia and West Africa—have been linked to human trafficking. Case studies by the Environmental Justice Foundation documenting so-called “modern slavery” practices in fisheries and/or aquaculture have included first hand and eye-witness accounts of child labor, deceitful recruiting, physical and mental abuse, hazardous working conditions, abandonment and/or refusal to repatriate, imprisonment, denial of fair and promised pay, and the withholding of official documents (i.e. passports).
The U.S. State Department’s annual Trafficking in Persons (TIP) Report seeks to assess how well governments are addressing and responding to the crime(s) of human trafficking. According to the 2013 TIP Report, “human trafficking” and/or “trafficking in persons” are umbrella terms for “the act of recruiting, harboring, transporting, providing or obtaining a person for compelled labor or commercial sex through the use of force, fraud, or coercion.”
Some of the most prominent seafood capture and export nations, such as Russia, Thailand, and China, have been implicated as failing to comply with minimum standards outlined in the Trafficking Victims Protection Act (TVPA) of 2000. For these reasons, up-to-date TIP Report information is of increasing relevance to the seafood industry. Each of the 188 countries and/or territories assessed in the TIP Report are assigned to Tier 1 (full compliance with TVPA standards), Tier 2 (working towards full compliance), Tier 2 Watch List (working towards full compliance but significant work remains), or Tier 3 (not making significant efforts to comply).
The U.S. imports 91% of the seafood sold in this country. The top 10 exporting nations and their corresponding TIP report ratings are:
- China, 23.2%, Tier 3
- Thailand, 15.5%, Tier 2 Watch List
- Canada, 11.9%, Tier 1
- Other Asian Countries, 7.9%, varies
- Viet Nam, 7.2%, Tier 2
- Indonesia, 5.1%, Tier 2
- Ecuador, 4.9%, Tier 2
- Chile, 3.8%, Tier 2
- India, 2.7%, Tier 2
- Mexico, 2.6%, Tier 2
These numbers are based on NOAA 2011 U.S. import volumes of edible seafood products.
Most notably in the 2013 TIP Report, both China and Russia received an automatic downgrade to Tier 3 for remaining on the Tier 2 Watch List for several consecutive years. Due to a recently adopted government plan to combat trafficking, Thailand was granted a waiver from the automatic Tier 3 downgrade (both China and Russia had received the same waiver in 2011 and 2012). There are currently 23 countries and/or territories with a Tier 3 designation, including North Korea, Iran, Saudi Arabia, Liberia and Yemen.
Seafood companies should begin to ask their suppliers about compliance with social standards to ensure safe working conditions throughout the seafood industry. The country ratings in the TIP report can be used for prioritization, and if problems are uncovered, companies should switch sources or request supply chains make improvements or seek certification.
FishWise will release a white paper on human rights in the seafood industry, including detailed recommendations for seafood companies, later this year.
In March 2011, the Fukushima Daiichi nuclear power plant in Japan suffered major damage when it was hit by a powerful 9.0 earthquake and subsequent tsunami, resulting in the largest nuclear disaster since Chernobyl. Over two years later, the Tokyo Electric Power Company (Tepco) recently acknowledged that radioactive water from the plant continues to leak into the Pacific ocean at a rate of nearly 300 tons per day, causing global concern about contaminated seafood.
Scientists have long suspected that radioactive water was still leaking into the ocean. Last October Ken Buesseler, a marine chemist from Woods Hole Oceanographic Institute, found that levels of radioactivity in samples taken from fish, shellfish, and algae around Fukushima were not declining with time. A new study published in the peer-reviewed journal Deep-Sea Research predicts that ocean water contaminated with radionuclides from Fukushima will reach Hawaii and the west coast of United States in early 2014.
Fears about the safety of seafood from the Pacific have prompted scientists to investigate some fish species for traces of radiation. To determine what effect the radiation is having on the marine food web further from Japan, another group of scientists from Stanford and Stony Brook Universities collected tissue samples from Pacific bluefin tuna caught off the coast of California. They found that all 15 tunas tested had trace amounts of radioisotopes from the Fukushima plant.
Given all this disturbing news, should we avoid eating seafood from the Pacific ocean?
Not according to the marine scientists who published the studies described above. Physical oceanographers are more excited than fearful of the radiation plume heading for the west coast. By monitoring the plume's spread across the Pacific, researchers can study long-term ocean circulation patterns and improve their models. Due to the rapid dilution of radiation in the Pacific Ocean currents, levels of radionuclides in the plume will be far below the U.S. Environmental Protection Agency's safe limits for drinking water by the time it reaches our shores.
The majority of fish tested in waters near Fukushima had levels of radiation that were well below safe limits for consumption. The level of radiation found in the bluefin tuna off California was also considerably lower than radiation levels that are naturally found in the fish. In fact, the significance of the studies was not necessarily the implications for human health, but rather that scientists could use the signals from Fukushima to understand bluefin migration patterns across the Pacific.
Unfortunately the key results from these studies have been misrepresented in the media, and have led to the concern that seafood in the Pacific may be contaminated from the Fukushima plant and is unsafe to eat. While Japanese subsistence fishers may need to take extra caution, people eating seafood from the eastern Pacific do not need to spend too much time worrying. The latest report released by the Stony Brook University researchers assures us that, “although uncertainties remain regarding the assessment of cancer risk… the dose received from Pacific bluefin tuna consumption by subsistence fishermen can be estimated to result in two additional fatal cancer cases per 10,000,000 similarly exposed people.”
