Distance from Kesennuma to Fukushima Daiichi:

Google Translation of Jan. 20 report in the Asahi Shimbun, Miyagi local edition:

Title: Oyster in North Japan grow as double as average
Source: Fukushima Diary
Date: January 21st, 2012

[At] Kesennuma, Miyagi [Prefecture…] last June […] oyster was 1~2cm at the time but they have already grown to be about 10cm, which is as double fast as usual. […]

Fisher’s experiment station of Kesennuma thinks it might be because the rivals of oyster died or nitrogen nutrition might have flown from ground soil by Tsunami. Nobody has considered the risk of radiation.

Title: Bumper Crop of Big Oysters in Miyagi Prefecture, Oysters Grew Extremely Fast
Source: EX-SKF
Date: January 21, 2012

From Asahi Shinbun Miyagi local version (1/20/2012):

[…] The shipment was scheduled for this fall, but the oysters grew so rapidly that fishermen decided to harvest and ship right away. The shipment will continue throughout the month. […]

According to [Tetsu] Hatayama, there’s an old saying that oysters grow fast after a tsunami. […]

“We decided to harvest sooner, otherwise the rafts would have sunk from the weight of the oysters. This is a special case, shipping this early, thanks to the earthquake/tsunami.”

[…] There is absolutely no concern for radiation in the Asahi article.

    No words,……only rage!

  • radegan

    I’m not reading here that anyone checked the oysters for radiation. Perhaps it’s in the original, if they’re radioactive, it must be Fuku – if they’re not, then the tsunami idea might be right. If there’s still a question – then they haven’t tested them.

    • Anthony Anthony

      The nitrogen idea seems odd to me….oysters are not Plants! I thought nitrogen is a gas one has to balance carefully in one’s aquarium? I think its radiation.

  • Are they even going to check for radiation ???

  • StillJill StillJill

    Well, where are they getting them from,…and why are they so big?

    • StillJill,
      Didn’t we see an article here that they were taking testing foods in their on hands ? Ship them where ???

      • StillJill StillJill

        Yes Doc,…I recall an article,…..citizens testing I think.

        Let us hope there is a small army of folks ‘in the know’,…there,…telling all til’ they’re blue in the face just like us.

        Another roommate tells me not to speak about Fuku. Damn censorship. To shut-up, or not shut-up,….that is the question.

  • harengus_acidophilus

    “Great deal honey.
    Today i’ve sold a NPP.
    Let’s have some oysters and champagne.”

    Maybe oyster eaters will glow in the dark soon…


  • Jebus Jebus

    Think of all the nutrients, chemicals, radionuclides, ect… that have washed out to sea from the tsunami and current runnoff.
    There is no wonder that you have big fatty oysters, given the sudden feast that has been handed to their little slice of the food chain.

  • Hemisfear311 Hemisfear311

    Radioactive oysters found by Greenpeace back in May, last year.


    “…Greenpeace said it found levels of 740 Becquerels per kilogram in oysters…”

    Now, seven months later Godzilla Oysters are pulled out of the ocean and nobody even consider that they may radioactive!

    Oysters are filter feeders and they filter enormous amounts of water for plankton. 50,000 oysters will filter about 1.2 million gallons per day.


    Are the freshly caught mega-oysters more or less radioactive than they were last May?

    Not too hard to figure out I’d say.

  • Al-Chemisto

    Let’s all thank the blessings of mother nature for this year’s crop and chow down!

  • jec jec

    @StillJill, just be careful. Those little critters..mussles, squid, clams, oysters..you name it are like the squid with radiation. A Fukushima Diary website reported on the squid with BETA radiation found processed and frozen. Was from the Pacific side of South America.

    • StillJill StillJill

      Not liking seafood has finally come in handy! I’m allergic to cheese too,….so my lifelong struggle is finally paying off! 🙂

  • Replacant Replacant

    Great oysters with a half life instead of a half shell ; ) But really no mention of radiation and testing? Its almost like the Japanese government thinks if we ignore it it will go away or doesn’t exist. What countries are dumb enough to import them, besides the US?

    • matina matina

      exactly, not mentioning radiation is an indication that its important. what is not being said is always more important then what is being said. when reading information i always ask myself – what does it justify? what does it say? what does it deny?

  • HoTaters HoTaters

    Asian grapefruits from tree in yard next door. 2-3 times size last year at this same time.

    • HoTaters, can you take some pictures and post them ?

      • HoTaters HoTaters

        Yes, but I don’t know how to get them posted here. Can anyone suggest the procedure for this? I have one wicked looking orange I picked up a couple of weeks ago, while out on a walk. It has a bunch of tentacles growing out of it, on the end opposite from where the stem attaches.

  • StillJill StillJill

    Well there,…maybe these nuke-pukes now have super-sized egos too, from the cesium, et. all

  • trinityfly trinityfly

    Maybe they are “Happy Oysters” so they must be good for you? We have mostly stopped eating seafood here. I do miss eating sushi here though. It is amazing how they can put out that news story and not even mention radiation contamination?? Why would the oyster farmers even consider farming them? Would love to know who is even buying them. Why wouldn’t the government inform them of the danger there product poses everyone? The Japanese government is a criminal enterprise. It would appear that there must be a planned extermination planned for the people of Japan? Conspiracy theory? There is no conspiracy theory!!

  • patman

    Thought that perhaps Japan’s prosperous oysters were the result of extra soil and nutrients getting washed into the sea.

    It’s been a thousand years since the last equally big tsunami; plausible that centuries of accumulated bone and top soil residue may jump start growth.

    However, we are also getting a parallel mussel growth surge in Canada. There was a report about a conglomeration of mussels that was threatening to submerge some expensive harbor netting.

    Newsworthy, no one was counting on that. Related phenomena? Didn’t say if the size was abnormal, or the quantity was greater. More sick plankton? Giantism?

    Any marine mollusk hobbyist/observers out there?

  • many moons

    WOW! All this time farmers have been beefing up their chickens with steriods and all they had to do was give them radiation and stand back. This is really a big discovery for the meat production industry…..they can make a KILLING! 10,000 burgers from 1 cow…wow! Thanksgiving, one turkey could feed 50 people.
    Oysters will be sold one at a time as a main course….
    Radaition, the supersizer!

    • Bobby1

      Hmmm… “Dat’s money comin’ outta dat nukular plant!”

    • patman

      Presume Japanese have a respect for food quality, not necessarily food quantity;

      Japan is a rich country, with less pressures that has corrupted North American ‘Agri-Biz’.

      Taste and nuance is what people who love food tune into.

      Does Japan even use much hormones, steroids and routine use of antibiotics in poultry husbandry? Chicken crap is very rich in nutrients and a great fertilizer, however.

  • StillJill StillJill


    Radiation gets into the water.
    Fish, plankton, and oysters live in said water.
    Said animals get radiation.

    Don’t eat said animals.

    Where’s my PhD???

    • Al-Chemisto

      pardon young one. you must understand the grants come only from “certain” sources. as such you must not touch certain tender subjects for fear that you become blacklisted and unable to land said grants.
      Ph.D. is nothing, surviving as one means being a liar. 🙂
      oh…pardon…i meant “selective in one’s perspective.”

      • patman

        Tender subjects? Not if everybody is suffering from this disaster. This is called a ‘paradigm shift’, and changes everything. Kind and generous people become esteemed.

        You want a Ph.D? Forget stupid job prospects etc, that is old thinking.

        New thinking is find an aspect of what you love and serves all of us, study it, ‘breath in’ your subject and related contextual issues.

        Then you -are- prestige. Collaborate with others in the subject and teach kids fun stuff you know. They will decide whether you are a Ph.D.or not.

        Of course, one still has to know how to count, communicate, reason, and be graceful.

        But it’s no longer about position, prestige and money. There is none; we are bankrupt.

    Shouldn’t we call this a nuclear level of Irony, not just brutally ironic?

    That everything natural will be hopelessly polluted,…..

    The most processed and human touched are the things we wont die from…. immediately.

    Makes you wanna think that the industrialized food processing industry might know something we don’t

  • chronic chronic

    If we can have Spam – processed pork parts – ?

    Why cant we have Spalmon – processed fish parts, without mosta the radiation?

    “According to [Tetsu] Hatayama, there’s an old saying that oysters grow fast after a tsunami. […]”

    wow, quite impressive, tsunamis are so common in japan that they even have sayings as such above? makes you wonder what thought process led them believe that they should build NPP on their shores!

    • patman

      Any tsunami in Japan would be a horrendous event, evidence if the significance is those high water stones on hills along the coast.

      Every sound, every observation AFTER the wave, would be recorded and contemplated upon. Tsunami waves are mythical in proportion; Takes virtually everyone in a few short minutes. Mysterious and rare enough to demand some plausible explanation by lost and suffering survivors in remorse.

      Stories of every bit of evidence after the wave would certainly be recorded and transferred to next the generation. Big oysters among fishermen? Definitely worth knowing.

      Probably an extended lexicon to describe these sea animals; every detail means something. Perhaps similar to Canada’s Inuit having extended vocabulary for the world around them, snow conditions can be described in very fine detail.

      But we do have something else going on today that has no historic context. That is the issue.

      • patman

        Oysters double in size?

        How about an industry for radioactive penis enlargement?

        Make a million dollars.

        Tears if it turns black and falls off, though.

        Giant lawsuits.

        Hmm, bad idea, forget it.

    Someone could make a buck selling these as a daring alternative to fugu. All the young dudes could show off – “I tasted a Kesenumma oyster and lived to tell about it” (or not).

    12. Chernobyl’s radioactive contamination of food and people.
    Nesterenko AV, Nesterenko VB, Yablokov AV.
    SourceInstitute of Radiation Safety (BELRAD), 2-nd Marusinsky St. 27, Minsk 220053, Belarus.

    ” Up until 1991 the United States imported food products with measurable amounts of Chernobyl radioactive contamination, mostly from Turkey, Italy, Austria, West Germany, Greece, Yugoslavia, Hungary, Sweden, and Denmark. These products included juices, cheeses, pasta, mushrooms, hazelnuts, sage, figs, tea, thyme, juniper, caraway seeds, and apricots. In Gomel, Mogilev, and Brest provinces in Belarus 7-8% of milk and 13-16% of other food products from small farms exceeded permissible levels of Cs-137, even as recently as 2005-2007. As of 2000, up to 90% of the wild berries and mushrooms exceeded permissible levels of Cs-137 in Rovno and Zhytomir provinces, Ukraine. Owing to weight and metabolic differences, a child’s radiation exposure is 3-5 times higher than that of an adult on the same diet. From 1995 to 2007, up to 90% of the children from heavily contaminated territories of Belarus had levels of Cs-137 accumulation higher than 15-20 Bq/kg, with maximum levels of up to 7,300 Bq/kg in Narovlya District, Gomel Province. Average levels of incorporated Cs-137 and Sr-90 in the heavily contaminated territories of Belarus, Ukraine, and European Russia did not decline, but rather increased from 1991 to 2005. Given that more than 90% of the current radiation fallout is due to Cs-137, with a half-life of about 30 years, we know that the contaminated areas will be dangerously radioactive for roughly the next three centuries”


  • Radiation Safety – Food and Drug Administration…

    “If radiation levels in any food reach the FDA intervention level, FDA will take action to remove the food from distribution. We will continue to keep you updated”

    My comment; maybe someone should tell them about all of the milk, and other foods/drinks in various US states exceeding this ‘maximum’… Or is the FDA intervention level 100 times the EPA maximum ‘safe’ level?

    Food irradiation – nuking foods for you

    Nuking foods prevents the foods from spoiling. Meat will last for a LONG time.. Would you meat that has been sitting around for weeks, or possibly even months?

    If we spray all food with a mixture of plutonium/uranium/cesium, will it EVER spoil?

  • cobolt90

    There was a little piece a month ago on Japanese TV about how well the sharks fin industry in kesenume was recovering – aside that they are destroying the blue shark population there was no mention at all about radiation. fukahire soup…?

    Here’s start…
    This deserves a better discussion…gotta do the job thing for a bit…

  • StillJill StillJill

    YES Heart! This is totally getting by as “good”! This giant-ism is bad, bad, bad!

  • Nigwil

    The oysters are indeed filter feeders. Its likely that the tsunami created a huge increase in the nutrients in the water which supported enormous algae growth which the oysters consumed; hence giving them their increased growth rate.

    But as they grow they ARE filtering and accumulating the good and the bad. And growing at twice the normal rate they will have filtered twice as much stuff o ut of the water. Its is very likely that the radiation has accumulated therein; and I wouldn’t eat one if it was offered on a gold plate (or in its own lead coffin!)

    I’ve decided for a number of reasons including Fukushima that the only diet for safe-as-possible survival is a vegan one, eating fresh organically-grown food grown within sight distance of home.

    Take care!
