Although no cases of mad cow disease have been confirmed in people or cattle in the United States, a Purdue specialist believes that individuals have died as a result of the disease. Although there is no scientific evidence to back up these claims, they have had an impact. Mad cow disease has never been found in any animal in the United States, so there is no risk of it spreading here.
People can become infected with bovine spongiform encephalopathy (BSE) or "mad cow disease" when they eat products such as meat and dairy products that contain the brain tissue of cows, sheep, and humans. BSE was first discovered in 1986. Since then, more than 10 million animals have been killed to prevent the spread of the disease.
In 1996, a human case of BSE was reported for the first time. The patient showed symptoms similar to those seen in people with Alzheimer's disease - mainly memory problems and loss of judgment. He was a 67-year-old man who lived in England and had eaten meat and bone meal before he became ill. This material is used as a fertilizer and contains parts of animals' bodies such as bones, horns, skin, and viscera. It has been suggested that this case may have been caused by contact with this material, but further studies are needed to confirm this hypothesis.
In 2003, a second case of BSE was reported.
Humans are unable to develop mad cow disease. However, in rare situations, they may develop a deadly human version of mad cow disease known as variant Creutzfeldt-Jakob disease (vCJD). This can occur if you consume nerve tissue (the brain and spinal cord) from Mad Cow Disease-infected cattle. VCJD is not contagious and cannot be spread from person to person.
In addition to nerve tissue, the body also contains other tissues that are used in blood transfusions and transplant operations. These include heart, lung, liver, pancreas, and intestine. It is possible for a person to contract vCJD after having contact with infected material such as blood or bone marrow. In these cases, the vCJD infection would have been passed on even though the patient did not show any signs of being Mad Cow Disease-positive.
It is very important to know that just because you do not have Mad Cow Disease does not mean that you are immune to vCJD. Only humans who have had contact with the brain tissue of Mad Cow Disease patients are at risk of getting vCJD. In addition, pregnant women or those who are trying to get pregnant should avoid any kind of meat product that has come into contact with brain tissue from Mad Cow Disease-affected cows.
If you are a health professional and suspect that a patient might have vCJD, then it is your responsibility to refer them to a center that can provide them with proper testing.
In addition to the cases of mad cow reported in the United Kingdom (78 percent of all cases) and the United States, cases have also been reported in France, Spain, the Netherlands, Portugal, Ireland, Italy, Japan, Saudi Arabia, and Canada. All cases confirmed by laboratory tests were caused by the same form of the disease: Alzheimer's-like brain disorder.
Mad cow disease was first discovered in 1986 when British farmers began finding parts of cows that had eaten grass contaminated with the waste products from bacteria that cause mad cow disease. Scientists later learned that the cows' brains contained abnormal proteins that included elements found in human brain tissue.
The cows affected were mostly older animals of both sexes fed milked regularly and kept as pets. No case of transmission to humans has been reported so far. However, because the disease affects the brain and mind, it can be difficult to diagnose. Patients may appear normal but will likely develop dementia or some other cognitive impairment over time.
Currently, there is no cure for mad cow disease. However, doctors are working on treatments that might help patients during their illness.
Mad cow disease is found for the first time in the United Kingdom in 1986. A British outbreak affected approximately 180,000 cattle and devastated farming communities from 1986 to 2001. The disease was named after the brain disorder it caused in animals: "mad cow" disease.
The origin of mad cow disease goes back years before it was recognized as such. In 1967, there were reports of a new disease in cows in Britain called "scrapie." This disease was similar to human Alzheimer's disease in that it involved the loss of memory and other mental abilities. Scientists believe that scrapie came from sheep that had been infected with a parasite called "mulga," which lives in the intestines of sheep and goats. When it infects cows, mulga causes them to act strangely and eventually die.
In addition to humans and cows, scrapie can also be found in mice, rats, and hamsters that have been infected with the parasite. It is not known how the disease is transmitted from animal to animal, but it seems likely that it is through the consumption of contaminated meat and dairy products. Although mad cow disease has never been reported in sheep, it is thought to come from cows that have eaten contaminated feed or pastures.
Mad Cow Disease can cause severe symptoms such as personality changes, muscular stiffness, involuntary muscle movements, dementia, and seizures. There is no cure for Mad Cow Disease; however, it can be prevented by not eating products that contain brain tissue.
Although rare, another member of the Bovidae family called vvss disease has been linked to human cases of spongy bone disease and mental impairment. This disease can be transmitted from animal to animal through saliva or urine, so avoid coming into contact with animals' feces or penises if possible.
In addition to mad cow disease and vvss disease, other transmissible spongiform encephalopathies (TSEs) can result in cognitive impairment or death. TSEs are diseases of the nervous system that affect both humans and animals. They are usually fatal unless you have a form of TSE that has been diagnosed early enough to allow for treatment.
People who are exposed to TSEs may become infected if they eat food contaminated with the virus. In addition, blood products, organs, tissues, and any other part of an affected animal can transmit TSEs to people who receive them via transplant or surgery.
