カナダ野生いのしし  Canadian Wild Boar


61,000 Bq/Kg from wild boar meat in Fukushima, the highest reading ever

In April 2013, the highest reading ever found in wild boar was reported in Fukushima Japan.  The test came in at 61,000 Bq/kg of Cesium 134 and Cesium 137. (1)

2013年4月、日本・福島の野生イノシシが、過去最高の数値をはじき出した。セシウム134/137が 61,000 Bq/kgという検査結果となった。(1)

What does this mean?

Even if you don't know what a Bq is, 61,000 of anything is a huge number.  But when you consider that one Bq (Becquerel) is one atomic disintegration every SECOND, this number can take on gigantic proportions. I will explain more about this later.

First, let’s take a few steps back to gain some understanding. When the reactors at Fukushima Daiichi exploded and melted down almost three years ago in March 2011, they released enormous amounts of radioactivity into the atmosphere.  Over 200 radioactive elements were released.  Just two of these elements were Cesium 134 and Cesium 137.

The first thing to grasp is that even though this wild boar registered 61,000 Bq/kg of Cesium, it probably contains extremely high levels of many other radioactive isotopes as well.

Because Cesium is relatively easy to test for, that makes it the test of choice for most researchers.  The wild boar in Fukushima was not tested for the other radioactive elements but you can be sure they are present too.

The second thing to understand is that radioactive fission products are constantly decaying in an effort to get to a balanced state.  Cesium 134 has a half-life of 2 years.  This means that it will take about 20 years before it has decayed away to it’s non-radioactive state.  Cesium 137 has a half-life of 30 years so it will be about 300 years before it finds it’s balanced state.

Thirdly, every time a radioactive element decays or disintegrates, it emits radiation that can damage tissue, alter DNA or otherwise wreck havoc in the human body. (wreckじゃなくてwreakでしょうか?)

And finally, one Becquerel equals just one of these disintegrations happening every second. When the researchers found 61,000 Becquerels in that kilogram of wild boar, that means that that kilogram of meat had 61,000 disintegrations going off in it EVERY SECOND.

 And that’s just the Cesium disintegrating. All the other radioactive elements that are in the meat are also decaying and releasing damaging radiation every second as well – we just don’t have the number for the other elements because no one tested for them.

Let’s assume that a person is unfortunate enough to eat a piece of that wild boar.  Maybe they would have an 8 ounce wild boar steak. There are 2.2 pounds in every kilogram so ½ a pound is equivalent to .227 kg. That 8 ounce steak has 13,847 disintegrations going off each second.  When the unfortunate person ingests the meat, those 13,847 disintegrations are then going off inside his body every second.

If you do the math – that equates to almost one million two hundred thousand disintegrations going on in the body in just one day.

Is this a problem?

When Cesium gets into the body, the body thinks it is potassium so it goes everywhere.  “It tends to concentrate most highly in the brain, muscle, ovary and testicles. There it can cause brain cancer, muscle cancers (rhabdomyosarcomas), ovarian or testicular cancer and, most importantly, mutate genes in the eggs and sperm to cause genetic diseases in future generations.” (2)

With well over a million disintegrations going on inside the body, eating such a piece of meat would most assuredly result in some serious damage to the body.

Levels of Cesium Rising in Fukushima, Japan

Over 10,000 Bq/Kg measured from 10% of wild boar meat sample in FukushimaThese levels of Cesium in wild boar have been increasing since March 2011. In March, 2013, 10% of the wild boar samples taken in Fukushima measured 10,000 Bq/kg of Cesium 134/137. Minamisoma City had the highest reading at 56,000 Bq/kg.  Researchers did not find one sample of meat that was not contaminated with Cesium. (3)

Four months before that, in November 2012, wild boar caught 50 kilometers from the Fukushima plant, registered 33,000 Bq/kg.  By April 2013, 5 months later, the levels of Cesium had almost doubled. (4)

Twelve months previous, in November 2011 and 8 months after the disaster, the wild boar in Fukushima was tested at 14,600 Bq/kg – less than half what was found 12 months later. (5)

The current (September, 2013) levels of Cesium in wild boar are now 400% higher than in November 2011.

Why wild boar have such high levels of Radioactivity

Wild boars are particularly susceptible to radioactive contamination. This is because they eat mushrooms and truffles which are particularly good at absorbing the radioactivity that has fallen on the soil and
in the water.

Fungi are one of the food items low on the food chain that concentrate radioactivity.  The wild boars are good at rooting out the fungi.  They eat large amount of these foods.  In fact, the mushrooms and truffles constitute the main part of their diet.

Add to that the fact that boars are near the top of the food chain and thus, as they keep eating the radioactive fungi, they continue to concentrate the radioactivity and build up the levels of radioisotopes in their bodies. (6)

Same phenomenon observed after the Chernobyl catastrophe

This same phenomenon was observed after the nuclear meltdown in Chernobyl in 1986. That disaster contaminated all of Europe and the wild boar across Europe built up high levels of radioactivity.

Recall that Cesium 137 is extremely long lasting and will be around for 300 years until it has decayed away.  That is why, over a quarter of a century later, the wild boars in Europe continue to show high levels of contamination.

In 2010, 24 years after the catastrophe, wild boar found near the Bavarian/ Czechoslovakian border were shown to have Cesium levels of 7000 Becquerels per kilogram.


Anyone have a Geiger counter?In 2011, tests done in Austria found radioactive Cesium in wild boar. The levels recorded were 1060 Bq/kg. And where did the researchers find the wild boar meat that they tested? It was being sold for human consumption in Austrian supermarkets! (7)

In 2012 it was reported that wild boars in the Sumava National Park, southwest Bohemia, still have Cesium from the Chernobyl accident in their bodies. (8)

In December 2012, Czech biochemists found high levels of radioactivity in the wild boar in their country – over 10 times over the limit. (9)

In March 2013, wild boars in the woods of Valesia in north east Italy showed levels over 600 Bq./kg (10)

In Germany, the “trigger” level , or level above which they are not allowed to sell wild boar for human consumption is 600 Bq/kg.

Radioactive meat found in U.K.

The Cesium contamination from Chernobyl didn’t just stay in Europe. It was also found in the United Kingdom, about 1500 miles away from Chernobyl.

Before the nuclear catastrophe in Chernobyl the average level of radioactive Cesium found in meat in the U.K. was less than 0.5 Bq per kilogram. ---Susan, wild meat or farmed meat?

Before Chernobyl, the total amount of Cesium consumed per year by one person totalled was around 100 Bq from all sources - plant, milk and animal sources.  (This radioactivity was left over from the nuclear bomb testing era.)

After Chernobyl, in the UK the levels of Cesium rose so that the government put a ceiling on the level allowed in meat for consumption. They tested meat and excluded all meat that was over 1,000 Bq per kilogram.

Words of caution

In spite of the fact that radioactive meat is still being found, the U.K. testing and the “contaminated meat exclusion program” was dropped completely in 2012. People in the UK can now eat radioactively contaminated sheep or other meat, with no radiation measurement or warning labels at all.

This is not only a warning to anyone travelling and eating in the U.K. You don’t have to be in the UK to get this meat - This also means that this meat can be exported to other countries like the U.S. and Canada.

Canada allows foods with Cesium levels up to 1000 Bq/kq to be imported. The U.S. government allows levels up to 1200 bq/kg. (11) These highly lax standards mean that foods that other countries will not allow their citizens to eat, could be imported to the U.S. and Canada.

In Japan, the level of Cesium allowed in their food used for human consumption is 100 Bq/kg.  Beware any food imported from Japan. The Canadian and U.S. governments allow the importation of food with radioactive levels well above those allowed in Japan.

A small Canadian study

One day going into our local butcher shop in north western Canada, we were surprised to see a sign that read “wild boar”.  Having followed the radiation levels rising in wild boar in Japan, the first thing we wanted to know was “ where did this boar come from?”  The answer – Drumheller Albert ,Canada. (Albertaですか?アルバータ州?)

Being aware that the fallout from Fukushima has gone many times around the northern hemisphere in the jet stream, we thought it would be interesting to find out if Canadian wild boar had escaped the Fukushima contamination.  If it had, then that would also indicate a possibility that the wild mushrooms, fungi and other food they eat may not be contaminated either.

We sent a kilogram of the wild boar meat to a laboratory certified to test for radionuclides. (GEL Laboratories LLC)

What is minimum detection limit and negative results? 

The concept of a minimum detection limit (MDL) is established to determine the statistical likelihood that the sample contains activity that is truly greater than the instrument background.検出限界は検体が、バックグランドよりも本当にレベルの高い放射性物質を含んでいるのかの統計的可能性を決定するために定められる。 
Identifying a sample as containing activity greater than background when it actually is not is known as a Type I error. As with most laboratories, the BNL Analytical Laboratory sets its acceptance of a Type I error at 5% when calculating the minimum detection limit for a given analysis. 検体が実際にはバックグランドより放射性物質が少ないのに、より多く含んでいるという結果がでることは「タイプIエラー」として知られている。ほとんどの研究所、BNL分析ラボでは、分析に使われる検出限界を計算する際、「タイプIエラー」を5%まで受け入れるように定める。 
That is, for any value which is greater than or equal to the MDL there is 95% confidence that it represents the detection of true activity. Values, which are less than the MDL may be valid, but they have a reduced confidence associated with them. Therefore, all data is reported regardless of its value.つまり、検出限界以上、あるいは同等の場合、95%は確実に実際の放射性物質のレベルを検出しているということになる。検出限界以下の結果は有効であるかもしれないが、確実性が低くなる。故に数値に関わらず、全てのデータが報告される。 
At very low sample activity levels, close to the instrument background, it is possible to obtain a sample result, which is less than the back ground. When the background activity is subtracted from the sample activity to obtain a net value, a negative value results. In such a situation, a single radiation event observed during a counting period could have a significant effect on the result. Subsequent analysis may produce a net result that is positive. Therefore, all negative values are retained for reporting as well. (by Plaza & Pante Consultants)バックグランドのレベルと近い微量の放射性物質のレベルでは、バックグランド以下の場合でも検体の結果を得ることができる。検体の値からバックグランドの値を引いて、マイナスの値が結果として出る。このような場合、測定中のたった1つの放射性の事象が結果に重大な影響を及ぼすことになる。引き続き分析をすることで、結果の数値がプラスになることがある。ゆえに、マイナスの値も報告される。
Although negative radioactivity is physically impossible, the inclusion of negative results allows better statistical analysis of the data. (by RadNet)マイナスの値は物理的に不可能であるが、結果を含めることでデータの統計的分析をより質の良いものにできる。

The lab was able to test for Cesium levels as low as 3 Bq/kg.  The lab did not find any Cesium in the sample.  There may be Cesium at levels lower than 3 Bq but the sample of wild boar from northern Canada did not have the incredibly high levels seen to this day in Europe and Japan because of the nuclear disasters at Chernobyl or Fukushima.

Some practical advice

1. Always ask where the wild boar was captured.

If you see wild boar on the menu the next time you go traveling, are in a restaurant, in the butcher or food store, be sure to ask where the boar comes from.

2. Avoid European and Japanese wild boar.

If you are in Europe, it will not be too difficult as, mostly, you will not find it on the menus in most restaurants.  When asked, most restaurants will discreetly tell you that “wild boar is not in season right now”. Beware though, and recall the wild boar that was found being sold in the Austrian super market.
(Dr. Helen Caldicott goes as far as saying she won’t eat anything that was grown in Europe).
(ヘレン カルディコット博士は、ヨーロッパ産のものは決して食べない、とまで公言している)

3. If you want to eat wild boar – Canadian may be a safer bet.
