UK Gelatin :: essays research papers
UK Gelatin Ã Ã Ã Ã Ã Bovine Spongiform Encephalopathy, or BSE, is a degenerative disease affecting the central nervous system of cattle causing the brain to appear as a sponge. The cattle then begin acting abnormally and eventually have to be killed. BSE can be transmitted to humans if they consume raw meat from an infected cow or if one consumes the eyeballs, spinal tissue, or the brain. This disease is known as Creutzfeldt-Jakob disease. Another disease similar to BSE, which is found in sheep, is Scrapie. Scrapie has been around for nearly two hundred years. It is presumed that the Scrapie agent jumped species and moved into cattle when sheep offal, leftover parts of butchered animals, were ground up and used as a protein supplement in cattle feed and the subsequently fed to cattle. Gelatin is considered safe for human consumption since its preparation involves a chemical process that destroys BSE infectivity. BSE-infectiousness is also destroyed during cooking and baking. Gelatin is manufactured primarily from the hides of pigs and the bones of cattle. During processing, these source materials are exposed to extremely harsh conditions, including prolonged exposure to highly acid or alkaline solutions. Gelatin is used in a wide variety of consumer and medical products regulated by the FDA. These products range from candies and desserts to vaccines, drugs, medical devices, dietary supplements and cosmetics. Ã Ã Ã Ã Ã In the unlikely event of any initial contamination of raw material, the gelatin manufacturing process would reduce BSE activity. The steps are as follows one hundred times by degreasing, ten times by acid demineralization, one hundred times by alkaline purification, one hundred times by washing, filtration, and ion exchange, and one hundred times by sterilization. Therefore, the combined effect of the processing stages gives a person a one in one billion chance of contracting BSE. The gelatin production process is efficient enough to remove and or inactivate minimal remaining infectivity. As a safety precaution, the use of UK bovine raw material for the manufacture of gelatin for food, animal feed, pharmaceutical, medical and cosmetic uses is not permitted under certain UK and EU legislation. All UK produced bone gelatin intended for these uses is made from non-UK raw materials. The UK manufacturing sites have to be registered with the Ministry of Agriculture Fisheries and Foods (MAFF) and regular inspections confirm that strict controls are met. These controls include full trace ability of raw materials. Consequently, UK produced bone gelatin can be considered to be the best controlled and monitored of any gelatin produced in the world, providing maximum reassurance to consumers.
