Bovine spongiform encephalopathy (BSE), better know as Mad cow disease is a relatively new disease. Most sources state that BSE first showed up in Great
Britain in 1986 [Dealler p.5] but some say it popped up in 1985 [Greger p.1].
However the official notification was not until 21 June, 1988 [Dealler stats.
p.1]. Spongiform encephalopathies are invariable fatal neurodegenerative diseases and there is no treatment nor is there a cure for this disease [Greger
p.1]. The recent scare of BSE has arisen because of the contraction of
Creutzfeldt-Jakob disease (CJD: see Appendix B) in humans from eating beef products. Although there are many forms of Spongiform encephalopathies that affect a wide range of animals, BSE has received the most attention because many people in the world consume beef and people are that they might contract the disease from eating a burger at their favourite fast-food restaurant. In this essay I will discuss BSE and other forms of Spongiform encephalopathies, how it affects the ani mal, what causes the animals to contract the disease, and the recent issues of BSE in the world. I hope to set out the true facts about
BSE and that it only affects a small percent of the world population. Due to the fact BSE is a new disease most of my information might be proven wrong in the future because there is a great deal of testing going on in the scientific community. They are also very concerned about this new disease and the effects it can have on humans if it is not stopped. Bovine spongiform encephalopathy is not some bacteria and it is not a virus, but in fact it is an infectious protein or prion [Greger p.2]. Before I go into more detail, I would like to discuss what a prion is. A prion is composed solely of proteins, and lacks genetic material in the form of nucleic acids. They are the tiniest infectious agents known, they can only be viewed under the strongest of electron microscopes

Mad Cow Disease Research Paper

... but there is a certain disease that makes people suspiciously zombie-like. This disease is called mad cow disease. There have always been a number of diseases and disorders that can turn a person violent, but they were also never contagious, until humans discovered mad cow disease. When a person becomes infected there are several symptoms that sound suspiciously zombie-like. Some of the symptoms related to mad cow disease include, muscle twitches, delirium, changes in how the infected person walks. If mad cow disease were to get out of control and turned our delirium into rage, and could be transmitted by blood, then humans could be just a bite away from a zombie apocalypse. Mad cow disease is a prion that affects cows. When someone ingests the infected meat they have a chance of getting the disease. It affects the...

Mad Cow Diseases: What Makes The Cattle Slaughter

...I found it interesting that the farmers use “drugs” to make the cattle bigger, before they are slaughtered. I disagree with this because I think the cow should just grow normally without any drugs. What happens to the people who drink the cow's milk? Would the drugs that was put in the cows be in the milk that is fed to humans? - Chapter 5 Another thing I found interesting is that sometimes cattle are fed other cattle parts. The farmers fed the other cattle old scraps because the cow’s needed protein. In 1997 the government banned the practice because people in England were dying of mad cow disease. Mad cow disease is a fatal brain disease. People or cows can get it from eating the brains of infected animals. Disgusting right? - Chap 5 pg 69...

...they have an extremely fragmented supply chain, with other correlated sectors and sub-sectors. The British beef industry includes large number of seperated producers and a combined retail and processing sector. Therefore, as the British beef industry consists of many suppliers the industry has an elastic supply. This is because the existance of large number of suppliers enable the industry to react or bring changes to the supply in accordance with the fluctuating demand. The British beef industry is worth £6.4 billion of the British economy, playing an important role in protecting the economy’s rural way of life and providing employment opportunities to more than 130,000 workers. The UK beef sector concentrates on cross breeding dairy cows with beef and as well as concentrating on the international market. Inconsistent or contradiction in composing of finished animals is the biggest challenge the UK beef industry is facing. Having a nature of large number of fragmented foundation of 63,000 supplies, this inconsistency leads to unnecessary costs that should be passed onto the consumers. This creates a negative impact on the quality of beef produced and the value of the customers towards consumption of beef compared to other alternative meats. The industry that is mainly affected due to the demand and supply fluctuations in the British beef industry is the poultry industry, which means that the change in demand and supply of British beef would have an huge impact...

Prions

...| Prion Disease | VET 140 Mr. Bell | Roger Meadows 5/7/2012 | A prion is a protein that has been mutated. Prion means proteinaceous infectious particle. Proteinaceous infectious particle can be broken down into:” proteinaceous which is relating to, resembling, or being protein, Infectious which is capable of causing infection, and particle which is a minute quantity or fragment” (Merriam – Webster 2012). So a proteinaceous infectious partial would be a very small protein that can cause an infection. The protein called PrP can be found in nerve cells all through the brain. The prion does not have a nucleus like other infectious dieses, and this makes it rare. Without the nucleus, it is not a virus or bacteria; it is only a protein (Hinz, A., Doremus, C., 1997). Prions cause a wide range of neurologic diseases in sheep, cows, and humans and were identified by Stanley Prusiner at UCSF in 1981 (Immunity and Disease, 2001). Prions are responsible for transmissible spongiform encephalopathies or TSE’s. Spongiform encephalopathies can develop three different ways, either by a normal prion changing into an abnormal one, or the PRNP gene that targets the creation of a protein which mutates into an abnormal protein, or consumption of contaminated items (Hinz, A., Doremus, C., 1997). TSE’s are very rare and affect around one person in every million each year over the world. TSE’s include bovine spongiform encephalopathy, or mad cow disease in cattle, scrapie in sheep, chronic...

Mad Cow

...What are Prions and their role? Prions are the proteins that cause Mad Cow Disease also known as BSE. Prions are an infectious protein. Prions are defined as an proteinaceous infectious particle, the protein is capable of changing the conformation of proteins to match its own and becomes infectious without the use of genetic materials. They can cross between species such as cattle, and sheep. Extreme heats chemical agents can inactivate the proteins. Prions are naturally occurring in the body and are not considered foreign nor do they stimulate the immune system and will not hurt your body, however the disease causing prions contact the normal prions by physical contact and alter the normal prions therefore causing the disease. With Mad Cow Disease The Prions target the specific protein in the cell that is normal called PrPC The role of protein Misfolding in BSE Diseased proteins result from improper folding and therefore the misfolded proteins induces copies of the same protein to also again misfold and increases the disease progress when it is misfolded. The scrapie prion PrPsc contacts and bumps into the normal cellular form PrPc intermediate and shifts the folding process converting them to the misfolded prion (the sheep version of mad cow disease called the PrPsc prion). The process continues over and over again. The body continues producing the normal cell PrPc and the scrapie prion PrPsc continues creating more replications of itself without needing any nucleic...

Supply

...the supply and demand aspect of economics. Several characteristics determine the causes for shifts in supply demand for milk. Milk is a product that almost everyone uses, and in most cases is viewed as a necessity. Milk is a product that will always be in high demand. This product is included in the food pyramid of healthy foods; therefore people will always want milk. There are however some factors that do affect the supply of milk. For example if a disease outbreak occurs in cows, the milk supply may drop. One aspect that has affected milk prices of in the past is Mad Cow Disease. Mad Cow Disease is an illness that has infected cattle since 1986. It is a disease that affects the brain. Since its first appearance in British dairy herds in 1986, BSE has affected roughly 200,000 cattle (Grace, n.d.). There was a more recent outbreak in America that caused cattle ranchers to put down several cows. As of November 2006, 3 individuals with mad cow disease had been identified in the United States (Kulger, 2006). Several cows were put down causing the supply of milk to decrease, because the supply decreased the price increased. The demand for milk stays virtually the same; people were just paying more for the product. People are willing to pay a higher price for milk because it is viewed as a need. When shifts occur in supply and demand, price, quantity, and market equilibrium can all be affected. As the price of milk falls in grocery stores, there is going to...

How the Zombie Apocalypse Is Totally Possible.

...How Zombies Could Actually Happen: A Research Paper Imagine a person infected with a disease to the point that they are some how no longer who they were before. The disease would take over the brain and make the body do only one thing, infect others. Sounds like a bad horror movie? Well think again. There are plenty of viruses, fungi, parasites, and chemicals in the world that affect the brain already and could cause such a thing to happen. The “zombie” wouldn’t be eating brains but it would want to spread the virus. Who is to say that a virus cannot mutate into something horrendous. This essay will show you that there are viruses, fungi, parasites, and chemicals that either can or have the potential to make people or animals into walking dead. Where did the idea of zombies come from? Zombies originated in Haiti as a sort of voodoo slave labor. What would happen was the person would be fed or rubbed with a mixture of the skin of the common toad and puffer fish. The skin of the common toad can actually kill people but the important part of it is that it is an incredibly strong pain killer. The puffer fish is extremely poisonous. It puts you in a coma in a near death state. People in Haiti are buried very soon after death and would be in the ground in less than 8 hours. The “dead person” would be dug up and fed datura, a plant with mind blowing after affects. According to Scientist Karl Kruszelnicki “Datura breaks your links with reality, and then destroys all recent memories...

For unknown reasons, a normal prion protein changes into a pathogenic prion that causes damage to the cattle’s central nervous system (BSE, 2013). Although these proteins are “normally found in the body”, “the infectious variety adopts a non-native, amyloid fibril-forming conformation that can cause other prions to adopt the infectious fold, presumably through protein−protein interactions” (More than just..., 2001). These fibrils are then often “deposited in tissue-destroying plaques throughout the body, including in the brain” (More than just…, 2001). In summary, these prions, once they become pathogenic, cause other prions to change as well. This formation causes tissue to become infectious, leading to destruction and death. Amino Acid with Side Chain Characteristics: • The carboxyl group has a non-ionized bond. This bond, C to the OH, means it can donate a hydrogen ion. This ability to donate a hydrogen, converting the bond to ionized, is what makes it an acid (Wolfe, 2014). • The amine group is basic, meaning it can accept a proton (H) (Wolfe, 2014).

The forces, bonds, and interactions by protein structures at the Tertiary level. There are Hydrophobic (nonpolar), Ionic bonds, Hydrogen (covalent) bonds, and Disulfide bonds, also called Disulfide Bridges. Hydrophobic are nonpolar bonds, meaning they cannot interact with water or aqueous solutions. Hydrophobic interactions will cause the protein to change shape to avoid making contact with such solutions. Considered weak bonds, but the proteins cluster tightly together on the interior of the protein, Van der Waals interaction take place between the proteins, again these are the weakest of the molecular bonds. Ionic Bonds are by definition bonds that are made up of charged particles. There are 20 Amino Acids, some with negatively charged terminals, some with positively charged terminals. This is a basic chemistry property that opposites attract. These are considered stronger bonds, but not the strongest. Next are hydrogen bonds. Considered stronger bonds than hydrophobic bonds, but weak compared to ionic and disulfide bonds. Hydrogen bonds are formed from Polar Covalent interactions. Two amino acids share a hydrogen electron and connect on the second amino acid oxygen atom. There must be a hydrogen donor on one amino acid, and a hydrogen acceptor on a second amino acid to complete the bond. The strongest...

Growth Hormones in Beef

...INTRODUCTION Did you know 90 percent of all beef in America is grown with artificial growth hormones (Hanrahan, 2000)? Were you aware that these growth hormones can potentially cause cancer and pose significant health risks to individuals who consume this meat? In today's food industry it is crucial to be a keen consumer and have knowledge of where you food comes from and what it actually contains. The regulations and standards put into effect by the US Food and Drug Administration (FDA) in regards to cattle production and what is deemed to be safe have created an up heave of controversy. Consumers and researchers constantly pose the question of what should be considered safe and who should not. They often argue that when it comes to human health no risks should be taken and risk assessment should not be considered. The following essay discusses the controversy of beef cattle production regulation and standards. The essay will analyze various studies conducted that state a possible link between cancer and growth hormone used in beef, and it will outline all view points of the European ban of American and Canadian beef. The issues and controversy surrounding feedlot given to beef cattle will be analyzed and consumer concerns as well as regulations surrounding labeling of beef in America, Canada and Europe will be discussed. ARGUMENT The use of growth hormones has become widely prominent in the beef production industry. Estradiol benzoate and progesterone, which are types...

...Issues Facing Canadian Farmers Today Canadian farmers face many problems such as dealing with the effects of international subsidies. One of the problems that farmers face is the loss of farmland. Due to urban sprawl and rural non-farm development Canada is losing thousands acres of farmland annually. We need to protect our farmland because it’s the base for our agricultural economy. On top of that, our farmlands provide a healthy environment to our wildlife. The American farmland Trust, a nation-wide, not-for-profit agency is working on the preservation of farmland for many years now. They believe that there are four fundamentals to creating growth strategies that benefit farmers, urban dwellers and suburban residents. One, being communities must plan out a good framework that balances out all interest such as work and transportation. Two, being subsidies which support sprawl over top quality farmland must be eliminated. Three, being the support of private landowners must be enlisted to help create land conservation and smart growth strategies. All levels of government must support and commit themselves to the protection of preservation of farmland and open spaces. Canada has good farmland and to pave over it for communities is not right. To make an inch of good topsoil takes millions of years, so there is no way of getting our farmland once it’s lost to the urbanization sprawl. Another problem farmers face are the decline of the family farm and the growth of agribusinesses...
