Although mad-cow disease is always fatal, it is not really much of a worry in the United States. There have only been four cases of mad-cow disease ever recorded in the United States. In every case, the United States Department of Agriculture has intervened and recalled tons of beef, 10,400 lbs. in the first case to be exact, in order to insure that the meat did not reach the plates of United States citizens.
In Canada, however, there have been 19 cases of mad-cow disease. This differs considerably from that of the United States. The interesting thing about all of the disease is that the first case of mad-cow disease was imported. The first case of mad-cow disease in Canada was from a cow imported from the United Kingdom. Then, the first case of mad-cow disease in the United States was from a cow imported from Canada.
The possibility of someone getting the disease from consumption of the meat is also very slim. In Europe, there have been over 200,000 cases of mad-cow disease and only 150 people have died from consuming the infected meat. So, really, the chances of you getting mad-cow disease from just eating the meat is very low. Even with that being said, I still believe that any cow with mad-cow disease should be dealt with accordingly, in other words killed and incinerated in order to stop the disease from spreading. If its meat has already been distributed the meat should immediately be recalled.
Now, mad-cow disease is carried by an abnormal protein known as prion. As you now know, mad-cow disease is transmitted through consumption. So, you may be wondering, how is it being transmitted through the infected cows to other cows? The answer is actually strange as well as a little disturbing. There are two ways that is currently b...

In cows with mad-cow disease, the area that is most targeted is the brain. The prions enter the brain and start deteriorating the brain. This is also why the disease is referred to scientifically as spongiform, because it causes the brain to look like a sponge with holes and empty caverns throughout the brain of the infected animal.
Another targeted areas of a cow with mad-cow disease is the spinal cord. The prions will also cause deterioration of the spinal cord. This is what cause paralyzation in some infected cows. The destruction of the spinal cord causes paralyzation because the prions deteriorate some of the nerves necessary for movement and feeling. Also, the spinal cord is linked so if prions devour one of those links, it would be similar to breaking the animal’s back.
...ases that are just as bad like CWD, but people have known about them. Mad Cow, BSE, vCJD--it is here and real and will kill anyone who gives it a chance. It does not pick an individual. It does not pick innocent or guilty. The people choose it. Mad Cow will either stop a person in his train of thought or fly past like a busy bee. This disease is not as well-known as some but is just as deadly. BSE has many terms all under the same definition. Whether a person sees this brain ravaging disease as a threat or a joke, it is up to each individual.
Mad cow disease is caused by prions, "weird mutant proteins that are found in brain and spinal tissue"1. Another name for mad cow disease is called bovine spongiform encephalopathy (BSE) and the definition is "a progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion"2. It started from what is called a prion protein then it turned into a pathogenic, and then it starts to damaged the brain of a cattle. There's another name for this disease and it's called Creutzfeldt-Jakob Disease "a form of progressive dementia characterized by loss of nerve cells and degeneration of nerve cell membranes leading to the production of small holes in the brain. It is rare, degenerative, and invariably fatal"3. This disease happen in human causing lapses in the memory, mood swings similar to depression, lack of interest and social withdrawal3. It is said that this disease has no tr...
Chronic Wasting Disease (CWD) is a fatal neuro-degenerative, transmissible spongiform encephalopathy (TSE) of the family Cervidae (Hamir, et.al., 2006). The family Cervidae includes mule deer, Odocolileus hemionus, white-tailed deer, Odocolileus virginianus, Rocky Mountain elk, Cervus elaphus nelsoni, and moose, Alces alces shirasi, among others (Sigurdon & Aguzzi, 2007). CWD is a prion disease, meaning it is a protein caused infection, that occurs naturally in the deer family (Song & Lawson, 2009). This protein is suspected to be an abnormal isoform (PrPSc) of the naturally occurring host prion protein (PrPC) (Blanchong, et. Al., 2009). Bovine spongiform encephalopathy (BSE), mad cow disease, is a similar prion effecting cattle as CWD affects Cervidae. Although, scientists are not sure of transmission route it is suspected that CWD is transmissible and infectious through direct contact with infected individuals or through environmental contamination (Song & Lawson, 2009). Tests have been performed showing susceptibility of altered mice to oral transmission, mimicking the suspected route of entry, and the incubation appears slower but lasts longer with oral infection (Trifilo, et.al., 2007). The approximate time from the initial infection to death is three years.
TSEs or more commonly prion diseases are a group of invariably fatal neurodegenerative diseases that occur in humans and animals . This disease is caused by a protease –resistant protein (PrPsc) after misfolding of a host-encoded prion protein (PrP). TSEs can exist as genetic, infectious or sporadic forms. The diseases are characterized by dementia, ataxia and neuropathlogically due to loss of specific neurons in the brain. Other clinical features include persistent painful stimuli, dystonia, visual or cerebellar problems and gliosis (1).
Normally, cows in Northern Europe in places such as Denmark live normal lives simply grazing on grass, and existing. However, there have been recent changes that have disrupted this normal activity. Generally the bluetongue virus (spread by Culicoides imicola, a biting midge) has been confined to Southern Europe and other places around the Mediterranean. But with the increase in temperature throughout the area, the midge has been allowed to migrate northward. This new pest is a nuisance and causes lots of difficulties to farmers in the area. When a cow contracts this disease, they usually also receive oral ulcers, salivation, stiffness, fever and eventually the inevitable- death (Merck Veterinary Manual NP). Because of the increase in temperature, midges have spread around the globe infecting livestock and creating terrible trouble for many farmers.
Bovine Spongiform Encephalopathy or Mad Cow Disease (BSE), degenerative brain disorder of cattle. Symptoms in cows include loss of coordination and a typical staggering gait. Affected animals also show signs of senility, for example, lack of interest in their surroundings, the abandonment of routine habits, disinterest in feed and water, or unpredictable behavior. Affected cattle show symptoms when they are three to ten years old.
Chronic Wasting Disease is a highly transmissible, deadly neurodegenerative disease that affects cervids in North America (Belay et al., 2004; Saunders et al., 2012). There are only four types of cervid that are known to get this disease which include elk, mule deer, white-tailed deer, and moose (Chronic Wasting Disease Alliance). It has been classified has a transmissible spongiform encephalopathy (TSE), otherwise known as a prion disease (Belay et al., 2004). A prion is an irregular, pathogenic agent that causes abnormal folding of specific proteins called prion proteins. These proteins are mostly located in the brain (Chronic Wasting Disease Alliance). The abnormal folding of this protein causes neurodegenerative diseases in a variety of species including humans, sheep, cattle, and deer (Abrams et al., 2011).
Prions are pathogens, and cause infections, like viruses. Prions cause many neurodegenerative diseases, but are made up of harmless proteins found in mammals and birds. The proteins are not in their normal form though, and once they enter the human brain, can cause severe brain infections. One thing that makes them different from viruses, is the lack of nucleic acids, which means they have no genetic code. Once in the brain, they make normal proteins turn into abnormal ones, which then multiply, causing severe infection. Soon, holes appear in the brain that can only be treated by incineration. An example of a disease caused by a prion would be the Mad Cow Disease, or the human equivalent Creutzfeldt–Jakob disease. Prions are very dangerous. While some people can confuse prions and viruses, there are some ways to tell the difference.
...eats contact. Finally, families who eat spinal or nervous tissue of cows can greatly reduce their risks of developing mad cow disease by not purchasing such items. The beef industry is willingly under surveillance, making all attempts to produce safe and healthy products. American residents should be assured that all necessary precautions have been taken to keep Mad Cow Disease out of the United States and consumer-friendly beef on market shelves. An excerpt from the FDA Consumer Magazine leaves the nation with this very “important message from both the Harvard and GAO studies. . . We must continue to work hard to make a good system even better. The FDA and the states will continue their aggressive inspection program and will continue to work closely with all components of the cattle and feed communities to help make a, thankfully, low public risk even lower.”
In 1997, approximately 35 million pounds of ground beef was recalled by Hudson Foods because a strain of E. Coli was found in the food. However, by the time the beef was recalled, 25 million pounds had already been eaten. Schlosser notes that the nature of food poisoning is changing. Prior to the rise of large meatpacking plants, people would become ill from bad food in small, localized arenas. Now, because meat is distributed all over the nation, an outbreak of food poisoning in one town may indicate a nationwide epidemic.
Did you know that a cow harvested specifically for beef only lives up to 18 months? The average cow usually lives up to 18-25 years! Today I will talk to you about the cruelty and chemicals that goes into the beef you are buying from your local grocery store. Not that I am in any way a vegetarian or against eating meat, but it is important for you to be informed about what goes into the food that you are putting into your body. You only have one, after all.

Creutzfeldt-Jakob Disease is an uncommon, deteriorating, consistently fatal brain disorder that is caused by prions. The symptoms of CJD are similar of Alzheimer’s but progress much faster. There are three variations of CJD, sporadic, familial, and acquired. All variations affect the brain the same way and have the same result of death. CJD is an untreatable and incurable disease.
Today’s medical experts say that avoiding meat helps you avoid saturated fat. They have found out from studies that women who eat meat daily have a fifty percent greater risk of developing heart disease than vegetarian women and a sixty-eight percent greater risk in men (staff writer). People may not know about serious diseases meat can cause such as, mad cow disease and foot-and-mouth disease. In the September 1999 issue of the Emerging Infectious Diseases, approximately 76 million food-borne illnesses- resulting in 325,000 hospitalizations and 5,000 deaths occur in the United States each year from improperly cooked or diseased meat (Licher). That is a lot of fun!
Cows are naturally very gentle and calm creatures. These smart and sweet natured animals have been known to go to great lengths to escape slaughterhouses. More than forty-one million of these sensitive animals suffer and die a painful death each year in the United States. When cows are still very young they are burned with hot irons, there testicles are torn or cut off, all without painkillers. Most beef cattle are born in one state, live in another, and are slaughtered in another. The cows who survive the gruesome transportation process are shot in the head with a bolt gun, hung upside down by there legs, and taken onto the killing floor where there throats
