To the scientific proof of a danger for man and animal ?

A recent study showing a link between electromagnetic waves and unexplained cattle deaths is bringing water to the mill of Stéphane Le Béchec, an Allineuc farmer who has lost more than 300 cows in four years.

One could have taken this dairy farmer in Allineuc, near Loudéac in the Côtes-d'Armor, for a madman, so much so that what he told seemed surreal. But a recent study, carried out by the scientific committee of a French association for the defence of the environment, gives solid reasons to think that Stéphane Le Béchec, is not an enlightened man.

This study is the brainchild of an independent group, toxSeek with a state-of-the-art research laboratory, born from the meeting between a doctor in pharmaco-toxicology, a chemist, a public health specialist and a high-tech entrepreneur.

Their investigation, the first conclusions of which were delivered last month, aimed to establish, on the one hand, whether there is a relationship between a high electromagnetic risk and a toxic impregnation with rare earths (metals found in magnets, telephones, televisions, etc.) in human beings.
On the other hand, the question was whether the existence of this relationship can be correlated with a decrease in the productivity of the animals studied and one or more animal pathologies. About ten farms were concerned by this analysis, including Stéphane Le Béchec's farm.

The latter, who claims to have himself become electrosensitive, has lost more than 300 cows in four years.


And I have lost 14 more since July 2020.

The cause of this <bb> frightening hecatomb? For him, it is sure: electricity and equipment that emits electromagnetic waves near his farm. Abnormal behaviour of the animals, pathologies and unexplained deaths, but also the absence of migratory animals or snails... The farmer has listed no less than 110 anomalies. "The presence of this type of metal (rare earths, N.D.L.R.) can also cause other pathologies such as leukaemia", he fears.

Scientists from toxSeek have notably observed that the average toxic impregnation to rare earths is seven times higher in farms subject to a high electromagnetic risk and experiencing significant health problems than in control farms where these problems are non-existent.

This is an exciting fact in terms of understanding the phenomenon, but one that still needs to be "dug up" by medical biology. This is what the laboratory toxSeek intends to do from now on, in connection with university hospitals.

For Stéphane Le Béchec, in any case, it is an important step in his long-term fight against electromagnetic emissions. It remains to be seen whether the study will be taken seriously by the competent authorities...

The impact on humans

The citizen collective Coll'Air Pur launched a hair analysis campaign on September 16, 2020 on National Air Quality Day. The study involved 76 children and 6 adults for a targeted search for metals, heavy metals and rare earths, carried out by the independent laboratory toxSeek.
Its aim was to find out the impact of chronic pollution in the Arve valley (Haute-Savoie), mainly on children. The 82 subjects of the study were compared to a control population of 988 adult and child subjects. A significant cadmium contamination was observed, 3 times higher than that of the control population, indicating chronic toxicity. Worrying results according to Dr Mallory Guyon :


Cadmium is a heavy metal with known effects on the lungs, kidneys, bones, cardiovascular system, brain and reproductive system. At chronic exposure doses, i.e. below threshold values, this heavy metal will have an impact on the body in the medium and long term.

The scientific committee toxSeek has identified a rare metals and earths contamination profile that could be a bio-marker of Electro-Hyper-Sensitivity.
This contamination has been discovered in the context of toxicological analyses of metals in hair, in several contexts : pediatric cancer clusters at Sainte-Pazanne ; farms in Nozay (Loire-Atlantique), in Brittany and in the Aisne (human and animal), people suffering from electro-hypersensitivity.
Hair allows chronic contamination with inorganic pollutants (metals, heavy metals and soil rares) : 3 cm of hair allow to study 3 months of contamination.


We put forward a hypothesis which is currently being researched by scientists : contamination with metals (rare earths) could be potentiated by electromagnetic fields (antenna effect).

In one equation:
contamination with metals (rare earths) electromagnetic fields = increase in effects and sensitivity, appearance of dermatological, neurasthenic, chronic disease symptoms....

This would be due to the magnetic properties of rare earths, which interact with electromagnetic fields.

The impact on animals

Following the results of the first toxicological analyses of dairy cow hair on five farms with significant problems (including Stéphane Le Béchec's farm in Allineuc), toxSeek emergency decided to initiate a case-control type study on the toxic impregnation with rare earths of farms subjected to significant electromagnetic fields.
As with human hair, cow hair can be used as a "biological matrix to highlight the bio-marker of rare earth contamination subjected to electromagnetic fields".

Toxic impregnation with rare earths 7 times higher

Toxicological analyses screening 49 metals, heavy metals and rare earths on cow hair of the 80 subjects were performed (ICP-MS technology). The scientific committee toxSeek observed that the toxic impregnation with rare earths of the dairy cows in the control farms is "very low or nil for a majority of the subjects".

On the other hand:


The average toxic impregnation with rare earths is 7 times higher in farms subject to a high electromagnetic risk and experiencing significant health problems.

The hair of 40 cows was analysed in problem farms to compare it with that of 40 other cows less exposed to electromagnetic risks.

For toxSeek, this study shows a correlation between the health status of farms, whose cows are subject to toxic impregnation with rare earths, and the electromagnetic risk. According to Matthieu Davoli, "we did not find anything in particular with regard to heavy metals (Editor's note: lead, cadmium, mercury, which are well known for their toxicity). On the other hand, there are differences in rare earths, so we can say that we are really onto something! "

The health challenge

Will the increase in electromagnetic fields (domestic, 5G, wind turbine...) coupled with rare earth contamination become a major environmental health problem?

What are rare earths?

All but land and all but rare. What are improperly called "rare earths" are actually metals, present in quantities comparable to those of nickel, for example, but infinitely more dispersed, which makes their extraction difficult.

They are essential to current technologies (flat screens, leds, computers, mobile phones, batteries...), to renewable energies (permanent magnets...) but also for the manufacture of some drugs, pesticides and MRI contrast products . Their magnetic properties are "20 to 100 times better than a conventional magnet".

Increasingly used, they are not, however, reprocessed or recycled.
