Many cows have died recently in Britain. Its creators suspect that cattle are victims of electric currents that pass through the soil. Is this a realistic explanation?
Their cows are dead because of electricity: this is what many Breton breeders are convinced. The Regional Health Agency (ARS) was seized by a mayor whose commune is concerned about this strange plague, France reported 3 regions March 24, 2019.
In Allineuc, a commune in Côtes-d & Armor, a farmer claims to have lost 200 cows in 3 years and suspects the blame is " electric currents Passing on the ground or in the water. In another city, one farmer reports the inexplicable death of 120 cattle. The animals also have strange behaviors (loss of appetite, decrease of milk production). The mayor of this commune, the one who took the ARS, points to " electricity in water at abnormal rates ".
" With electricity, we die immediately. 200 cows in 3 years, I've never seen this Jeanne Brugère-Picoux says by telephone. She is an honorary professor at the National School of Veterinary Medicine in Alfort, specialized in the medical pathology of domestic animals and animals.
A similar case in the early 2000s
This is not the first time the researcher has heard of such a situation. In 2003, she became interested in dairy farming in Normandy, where 45 died since 2001. The trace of her proximity to electrical installations is evoked. " A geobiologist has put it in the checking account "For her part, she prefers to focus her research on the metabolism of cattle.
In his study, he concludes that " the problems encountered are mainly related to food and construction "Jeanne Brugère-Picoux is convinced that this is a food problem at the root of laminitis, a disease of the hoof (foot inflammation) that can affect cattle." Understanding the digestion of ruminants is complex. But it was a metabolic disorder, they needed more hay when they got too much grain She remembers.
This experience leads him to relativize the conclusion that the cows died in Brittany are victims of an electric current that passes through the soil. " This is extremely suspicious. Did the creators really look for a diagnosis? A vet came to visit us? For me, it's more likely to be fraud. "Jeanne Brugère-Picoux continues.
"Electrical current": what are we talking about?
" If we attend to the electrical phenomenon, we must distinguish the primary source and the local source "Explains Laurent Quiquerez, a professor at the Claude-Bernard Lyon 1 University, who specializes in electronics. In relation to the primary source, the researcher points out that" each electrical installation locally injects current into the ground It is " if the installation is well done, this current is negligible ".
Laurent Quiquerez explains that the current injected by the primary source into the soil « dilute "Gradually – every time the distance from the installation is doubled, this current is divided by 4." But there may be weak resistance paths favored by the electric current He watches. Where the animal is, we can speak from a local source, to designate " a local current and the local soil facility to conduct this current ".
Finally, the scientist is interested in the animal: " an amount of current can pass In your body, depending on your size. " However, the resistivity of the nails (animal hooves) is high, so the current is low in the absence of a layer of water (rain, dew) »Continue Laurent Quiquerez.
For our interlocutor, it is probable that the intensity of this current is smaller than that found in the electric fences of the farms. " Only differences in exposure (continuous, rather than exceptional), differences in the body parts involved (abdomen or paws and muzzle), differences in characteristics (frequency, signal strength) could possibly give different behaviors, even if death of animals seems unlikely "Summarizes the specialist.To find out more, he tells us that we should know the results of the measurements made on the spot.
Cédric Berthod, electrical engineer graduated from ESME Sudria Paris, adds: « Electricity does not get stagnant. The earth is electrically conductive, but only in case of failure or impact of lightning. A human fears nothing, then a cow even less because its resistivity [ndlr : la résistance à la circulation du courant électrique] is even greater. "
Breeders suspect these electric currents will pass through water. It's possible? " Like earth, water is conductive, answers Cédric Berthod, but if there was danger, humans should die before the cows. According to him, there is a proven case in which cattle are more exposed than humans: love at first sight. This difference is explained by the greater distance separating the legs (compared to the legs). However, lightning strikes do not seem to be questioned by breeders of the Breton breed.
Cases of dead cattle by electrocution
There are many cases of cattle death by electrocution. In 1994, Henri Brugère, a former professor at the National School of Veterinary Medicine in Alfort, wrote in the Bulletin of the Practical Veterinary Society of France that " electric and magnetic fields of very low frequency can exert effects on the living beings ".
He added that the imputation to an electrical accident is not always easy, because the injuries can be very discreet and the electrical anomaly is not always detected immediately "In this study, the researcher is interested in electrocuted animals, whose death occurred suddenly.In the case of Breton breeders, the animals also present behaviors considered abnormal.
The Electricity Transmission Network (TEN), the company responsible for the management of France's high-voltage transmission network, also clarified the matter. " 50Hz magnetic fields, such as those emitted by power lines, have no direct impact on the health of farm animals Explains the network in a report in 2013. Animals may be sensitive to parasitic currents In " faults in the electrical installation But the RTE writes that " this phenomenon is not dangerous "- although it may provide stress in animals.
Contacted by us, the Regional Health Agency of Brittany confirmed to have been apprehended by a mayor in the center of the Great Britain. " It is important to determine the origin of these phenomena described on various farms, in particular by examining the electrical environment more broadly. "Answers ARS Britain, referring to the Ministry of Agriculture.To know the end of the story, we will have to wait for your answer.We bet it will not be electric.
