Bovine Spongiform Encephalopathy - Jessica



It was as if the most beautiful drawings of farms were inspired by this particular farm, so wonderful, nothing had touched it but Gods hands. The grass was always green; the house was surrounded by blue, yellow, purple, and pink flowers. The garden was over flowing with vegetables and fruits sprouting giving a good sign that this year was the golden year. The cows roamed freely with in their home lands, fat and happy. But all of that came to a quick end in December of 1984. It was three days before Christmas in 1984 when the first cow had been spotted with a strange and distracting behavioral change on Peter Stent’s farm. (Walters 19)
The Stent’s first had brushed aside the cow’s new personality and ignored it for a while. But soon more cows had become ill and they acted strangely the same.  Therefor the famer had become very concerned for his cows and he figured it was time to call his personal veterinarian Bee. Bee had no idea what was wrong he went through many scenarios and finally came to the conclusion that it had something to do with the cows’ brains. (Walters 20) On this farm was indeed the first reported case of BSE in London in the year of 1984. (Walters 23)
This first breakout was the start of something scary. Something no one was expecting; it had become a nightmare. Left and right there were cows turning up with the symptoms signifying that they were marked by the deadly disease. Questions bounce off everyone’s mind wondering what and where this mad cow disease had come from, what happens to everyone and everything after the disease hits, and how will everyone react?
Well, Bovine spongiform encephalopathy commonly known as mad cow disease, or BSE, is where the brain decays into a spongy mass, slowly but the results always ends with death. (Clark)  There is yet a cure to be discovered. It is caused by proteins in the brain and spinal cord, known as prions that inexplicably change shape. (Cooper) Described by one reported, bovine spongiform encephalopathy is a rare and unexplainable brain disease that rapidly and severely affects the brain, has no cure and is eventually fatal. (“Man’s”)  British scientist actually had suggested that mad cow disease had come from outer space carried to Earth in a meteor shower. (Copper) although mad cow disease is not a natural disease, it did not come from outer space. It is not natural because cows are not “naturally” carnivores. Said by Clark in his report “To avoid waste animal remains (including the brains) were grounded up and added to animal feed- a mind is a terrible thing to waste.”  This is the sole reason how the disease started. It is now thought that a flip flop event turned a regular prion into something that changed completely, causing the cow to go crazy somewhere in the 1970’s. But we could not see that the cow went crazy until 1984 when one cow showed physical side effects to the disease.
So now it is believed that the cattle get the mad cow disease by eating other cow’s brains that had been grinded up and put in their feed. And these cows that were eating the brains were healthy but does that mean that the cows that were grounded up healthy? The answer is no. Many had died from other diseases and then yes there were a few that died from old age, but even that is enough to flip a prion around. Mad cow disease also occurs spontaneously in individual cattle, but very rarely does this happen. Only one in a million cows does this occur. (Cooper)
After one cow had gotten it, the disease had spread like wild fires throughout England. Cows were dying everywhere you look. Going crazy and falling ill and then dying shortly after. In January of 1993 the mad cow disease had reached its peak. There were nearly 1,000 cases reported every week. (Cooper) This had made everyone fearful.
The first case of mad cow disease in a human came shortly after the first of the cows. The word had not gotten around that the cows were coming down with something therefore the people in England were still eating infected cows. The disease in humans later became known as CJD or mad cows in humans. (“Tens”) About 24,000 people in the UK were carrying the deadly brain condition, which was indeed the twice the number of people that were estimated to carry the disease. This many carriers is significant because there is a very high risk that this could even spread more by the disease through blood transfusions or surgical instruments. (“Ten’s”) The Health Protection Agency had said that one in 2000 of the adult population of Britain were carriers of the condition.
Calculations based on BSE in humans since the outbreak started had suggested an average incubation period is about 17 years. The total number of cases expected is estimated to be 200 to 300 cases reported. These estimates are much lower than many earlier and overly emotional predictions and reflect the extremely low infectivity of prions when crossing the boundary from one species to another. (Clark)
We can only prevent mad cow disease if we stop feeding herbivore animals meat; especially meat that is infected with diseases and flipped prions causing the cows to go crazy. We need to take a step back and look at what we did and learn from this. Feeding them natural grain and grazing them is the only way to go to my belief. I also believe that if we stick to not feeding them animal remains anymore we can get rid of mad cow disease completely, excluding that one in a million flipped prion. Therefore we would have to slaughter that one cow and get rid of it immediately.
Mad cow disease first broke out in England in 1984 and has sense killed more than 150,000 cattle and before the 1984 in England the disease was unknown. (Clark) In my opinion the biggest, by far, effect is all the deaths that the mad cow disease has taken from us. Not only has the cattle industry diminished but there have been lives taken from our population as well.
When people get CJD it is a terrible and sad condition, because you see the people around you surly and quickly loosing it. When it first out broke in people, we weren’t really sure what was going on at first. For example a young man at the age of thirteen was well on his way to be an amazing person. He had already became an Air Cadet, and was on his way to joining the RAF after high school. But when he reached the age of 18 things ended up going in the opposite direction quickly. His grades fell dramatically and he became withdrawn. They later diagnosed his symptoms with depression, and gave him antidepressants but his condition had only become worse. Sadly on May 21, of 1995, a month after this young man’s 19th birthday, he had past away from an unknown disorder. This sad story turned out to be the very first known human victim of mad cow disease. (Cooper)
Often the symptoms in humans for mad cow disease are; loss of memory, loss of coordination, drunk- sounding speech, weight loss due to the fact that they lose the ability to eat or talk, and in some cases they suffer seizers. (“Man’s”) It is clear in all autopsy tests that humans that have CJD have a massive loss of brain cells. Therefore that gives us a clear image why many of the victims are considered crazy for they have lost their brain technically. And when the brain is viewed under a microscope the brain tissue appears to look spongy. (Copper) The average age of CJD is about 28, but it has affected everyone young and old. In 1996 10 people had died from the mysterious disease, but when 2001 rolled around nearly 100 people have been killed from CDJ. Some experts say that it could eventually infect 275,000 people. Meanwhile bovine spongiform encephalopathy has slaughtered over 180,000 known to be infected. (Cooper)
Governments in Europe and North America have now banned feeding supplements containing meat and other ruminants, such as sheep and goats to other ruminants. But because between the infection and physical symptoms could be 30 years, we may not know if the regulations are even working. (Cooper) And now critics worry that it is only a matter of time before the disease pops up again in another part of the world. The reason why they believe this is because many other new countries do not have any regulations and they will by feed for their cattle that has ground up remains in it only because it is cheap. For example the U.N. Food and Agriculture Organization had come to the conclusion that cattle in more than 100 countries may have already been exposed to the mad cow disease.
When mad cow disease had infected the people it was different, we gave our all in saving them. But when it was the cattle that fell ill, some tried their best to save them but they were slaughtered quickly to attempt to stop the rapid spreading of the disease and to also stop the suffering. According to Clark, the Secretary of Health had stated that by May 1996, BSE had affected 160,000 cattle on more than 30,000 English farms.
As more cows were infected the more the beef industry went down as well. British beef was banned from many nations, despite the fact that the British government attempted to keep the campaign secret. (Clark)And now many countries have a long list or regulations that any beef coming from another country has to go through before they buy any. Putting everyone’s beef harder to sell and causing everyone to drop the prices until the beef industry will come back up again. Although we still do not know if BSE is out of our system our beef prices have rose but some are still scared and may never eat beef again. (Cooper) People had gone as far as marking sealed packages of any meat to assure the buyers that the meat was tested and they were 100 percent sure that the disease had not infected this product.
After I had taken in all of this information I had wondered how the government handled these situations, did they try to hide it or were they open with what was going on. But when I kept digging many of the fingers pointed to the government trying to hide.
            “When a new problem arises in society, especially a novel health issue, the response of the political establishment is pretty much as followed: ‘The problem does not exist.’ ‘The problem is extremely rare and, in any case, is declining. There are more important things to worry about.’ The problem has been highly exaggerated by irresponsible activist and popular journalists.’ There is a serious problem, and we have been doing everything possible to deal with it from the very beginning.’(Clark)
Clark believed that the political response was the government lying to us and our families. In 1995 one gals’ daughter had died from mad cow disease and the government’s response was only to tell her that that is impossible because mad cow is not in humans and that he needs to make that clear for everyone else to see. (Clark) Finally the lying had stopped in March of 1996 when Dorrell, from Secretary of Health had admitted that humans were infected with mad cow disease by eating beef products.
Although the government had attempted to cover up the tracks left behind from the disease, they did attempt to protect the people as well. They had attempted to regulate the beef and their feed to stop the spread. They had also slaughtered many cows to stop the spread. (Cooper) But sometimes that’s just not enough. Said by Gray George director of the food safety and agriculture program, “If the government is enforcing there new regulations and if the job is being done well- and that’s a big caveat- I believe that we’ve minimized the chance that, if a case of BSE ever happened here, it would end up being a major risk to human health.” (Cooper)
Have you ever wondered what it would be like if an outbreak happened here in America? Well I have and it turns out that we have had cases reported but we weren’t hit like England was. We kept it well contained, but the disease had regained attention for a small handful of cattle had been infected in the United States. Consequently, several countries have instituted restrictions on the import of American beef. (Clark) Also there was an outbreak in California recently last April. But the dairy cow was not an endangerment because they had put the cow down shortly after the figured out that she contained the disease. (New Case)
To me the mad cow disease is an important issue and we can address it calmly and get out on top rather than fussing about making everyone scared and hiding it is not the solution either. All we must do is not feed herbivores meat, which only makes sense.  
In conclusion if you are still terrified and not sure that the government is not doing enough to protect the health of the people, there are a few tips you can follow to make you and your family feel more confident that you will not acquire mad cow disease. Number one, choose meats that are muscle cuts because then you are staying away from the bone which gives you less of a chance to eat the nervous tissue. Next stay away from ground beef, hot dogs and sausages because these cuts are more likely to have the nervous tissue in them. Thirdly, which is most obvious, do not eat any meat that comes from any outside countries that have a past of outbreaks, because they have all the more chance to have the disease in them than anything else. (Prevent Mad)
Overall we still have yet to find a cure for the horrible mad cow disease but there are many ways to prevent getting mad cow disease. Keep your eyes peeled when shopping for meat and stay away from foreign beef. Even better we can prevent mad cow disease entering the cattle by not feeding them any more grounded up infected or any dead animals all together. We must take care of the people and the cattle that are infected instead of abandoning them. The cattle industry is very important to us as humans and to our government. I encourage people into finding the cure. And I trust that the government will protect us and our livestock.
