However the official notification was not until 21 June, [Dealler stats. Spongiform encephalopathies are invariable fatal neurodegenerative diseases and there is no treatment nor is there a cure for this disease [Greger p. 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 animal, 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. 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 [see appendix A]. Most scientists are puzzled because nucleic acid is the basis reproductive material needed in all other life forms [Britannica vol.

Because of their unique makeup, prions are practically invulnerable. They can survive for years in the soil. Only marinating your hamburger in Drain-O would make your burger safe to eat [Greger p. BSE, is a slowly progressing degenerative disease affecting the central nervous system of cattle.

BSE is the same as most of the other spongiform encephalopathies, they evoke no immune response and consequently slowly accumulate for an incubation period up to 30 years. You cannot detect them, purify then, nor can you isolate them [Greger p.

One of the main issues that affect most farmers is how do they know if a cow has BSE. Cattle affected by BSE develop a progressive degeneration of the nervous system. Affected animals may display changes in temperament, such as nervousness or aggression, abnormal posture; incoordination and difficulty in rising, decreased milk production, or loss of body condition despite continued appetite [Kent p.

However it has been noted the signs in American cows is much different. They instead stagger to their death like downer cows do.

There is no treatment so all affected cattle die. The incubation period ranges from two to eight years [Hodgson p. This usually takes from two weeks to six months. Most cases in Great Britain have occurred in dairy cows between three and five years of age [Dealler Bio p. The parts of the cow that is affected by BSE are the brain, spinal cord, and retina from naturally infected animals have been found to be infective and also the lower ileum intestine from experimental cattle inoculated was found to be infective [Varner p.

Great Britain is the site where the major problem of BSE started. The increase of BSE in the UK was mostly due to the fact that farmers were feeding their cattle a bovine food which included parts of dead sheep that had scrapie [see Appendix B.

This method of preparing the bovine food started inin order to be protein concentrated which in return made the cows increase their milk yield.

Most people did not know BSE could be transmitted through the food derived from dead sheep and cattle. Because the normal incubation period for a cow is years, most of the BSE infected cattle did not start to show signs until sixth and seventh year.

Most of these cows were then recycled into bovine food, which was then feed to more cattle and more cattle became infected. It was not until July of that the feed manufacturers were issued a warning to stop the production of bovine food with the presence of cattle offal that were infected with BSE [Dealler pg.

And it was not until 25 September, that bovine offal were specified to be banned from the food of all species [Dealler stats. In the British Government stated that BSE could not be transmitted to any other species because it was the same as scrapie [Greger p.

They were proven wrong and within a few weeks a cat died of a hitherto unknown feline spongiform encephalopathy contracted from an infected cat food. This caused an all out worry in Britain, fearing that BSE would spread into the human population. Nursing homes, hospitals, and more than schools stopped serving beef or restricted its consumption to a minimum [Greger p.What exactly is Mad Cow disease?
