Introduction: the European Commission announced on the 28th that experts have confirmed for the first time that species other than cattle and people are infected with BSE A group of experts from the European Research Center for bovine spongiform encephalopathy confirmed that a French goat slaughtered in 2002 actually died of BSE rather than scrapie The goat became the world's first confirmed case of BSE At the same time, experts say there is little chance that humans will be indirectly infected with BSE from sheep For the first time in history, "a goat suspected of contracting bovine spongiform encephalopathy was slaughtered in France in 2002, and today the panel confirmed that it was indeed infected with bovine spongiform encephalopathy," the European Commission said in a statement Bovine spongiform encephalopathy, commonly known as mad cow disease, is a fatal infectious disease that endangers the central nervous system of cattle It has only been found in cattle before "This is the first case in the world of natural transmission," said Philippe Todd, a spokesman for the European Commission According to the French Ministry of agriculture, the sick goat was born in 2000 in the aldish region of southeast France After suffering from an infectious disease in 2002, it was slaughtered with another 300 goats at a slaughterhouse in ales, southern France After brain tissue was extracted, all goat bodies were destroyed In October, the goat's brain tissue was randomly sampled and sent to the European Research Center for bovine spongiform encephalopathy in waybridge, southern England, for testing Until now, it was thought that goats were suffering from itch disease According to the research center, the goat had bovine spongiform encephalopathy After testing, the rest of 300 goats slaughtered were not infected with BSE The theory that bovine spongiform encephalopathy may cross infection among species has been confirmed In the past, sheep, not goats, have been studied as the targets of BSE infection in the laboratory, because sheep are the majority of people suffering from sheep itch disease Sheep itch disease is similar to mad cow disease, which belongs to spongiform encephalopathy So far, sheep have not been found infected with BSE The chance of the disease infecting people is very small Although the spongiform encephalopathy has penetrated into the sheepfold from the cattle pen, experts believe that the chance of the disease infecting people is very small "I want to reassure people that EU security measures are providing very reliable protection," said Marcos kiprijanu, European Commission Commissioner for health and consumer protection Strict food hygiene and animal husbandry rules will ensure that people can eat mutton, cheese and drink goat's milk at ease Dairy products are not affected by mad cow disease "in the European Union, prevention measures to protect consumers from the disease have been implemented for many years, and the risk has been minimized," the European Commission said The European Union has been banning the use of animal viscera as feed and demanding the destruction of certain dangerous organs The French goat producers' group also said it was not worried about the disease because dairy products are not affected by the disease The European Commission says 140000 goats in Europe have been screened since 2002 The European Union plans to screen another 200000 goats in at least six months, conduct more in-depth research on BSE, and focus on EU countries that have found cases of BSE BSE was first discovered in West Sussex in 1986 After eating the contaminated beef, human beings will suffer from a new type of Creutzfeldt Jakob disease caused by mad cow disease, which will lead to spongiform degeneration of brain nerves, resulting in nervous disorders, balance disorders, muscle contraction and eventually death In Britain, 148 people have died of the disease France, Ireland, Canada, Italy and the United States have also died of the disease Bovine spongiform encephalopathy, also known as mad cow disease, is an infectious disease that endangers the central nervous system of cattle BSE was first considered as a new nervous system disease in cattle When veterinarians from the laboratory of the national veterinary center of Victoria Bridge dissected the brain of the sick cattle, they found that the brain tissue of the sick cattle was spongy According to the pathological changes, the nervous system disease was named bovine spongiform encephalopathy in November 1986 There is no unified understanding of the etiology, pathogenesis and epidemic mode of BSE in the medical community, and no effective diagnosis and control measures have been found But experts generally believe that BSE originated from sheep itch disease, which was caused by feeding ruminant protein feed containing sheep itch factor to cattle Experts believe that mad cow disease is related to a communicable medium This medium is very stable and has strong resistance to heating, ultraviolet, radiation and various chemical disinfectants Ordinary cooking temperature, disinfection, freezing and drying measures cannot kill it Sheep pruritus, also known as sheep pruritus or sheep pruritus, is a latent disease that endangers the central nervous system of sheep and goats Sheep's itch disease is similar to mad cow's disease It is infectious and belongs to subacute spongiform encephalopathy, but it has not been found that it can infect human beings The etiology of sheep itch is still controversial in the medical community Most scholars think that the itch factor is a kind of "microprotein infectious particle" - prion without nucleic acid There have been reports of sheep itch in many countries in the world The earliest records of sheep itch disease appeared in 1732 and were introduced into Britain in 1840's The first confirmed case of sheep itch in the United States occurred in 1947 Canada, Germany, France, Brazil, the Netherlands, Switzerland, Belgium, Ireland, Norway, Japan and other countries have found the disease At present, there is no special term for "mad sheep disease" Before that, there was a saying of "mad sheep disease" in media reports, but it should be regarded as a general and easy to understand reference to sheep itch disease.
