Prions are natural proteins of animal tissues that may misfold and turn contagious. They are not considered as viruses or cellular organisms as observed by means of medical microscopy using a microscope. In their normal noninfectious status, these proteins may be included in cell to cell interaction as monitored through medical microscopy using a microscope. Once these proteins become unusually shaped such as contagious prions, they are deemed to come into contact with a normally shaped protein and convert that protein into the abnormally shaped prion as observed by means of medical microscopy using a microscope. This procedure initiates a geometric rise of abnormally shaped prion proteins until the number of abnormally shaped protein triggers overt disease. When ingested by animals, prions are believed to be taken up into the body in the course of digestion where they start the procedure of varying their normal protein counterparts into abnormal proteins. Nevertheless, as observed by means of medical microscopy using a microscope, contagious prions from one species of animal have fewer of a potential of initiating the abnormal shape in the normally shaped prion proteins of another species known as the species barrier. While the prion theory of Transmissible Spongiform Encephalopathies or TSEs is globally recognized, there are other theories of the basis of these diseases.

Prions are linked with a group of illnesses known as Transmissible Spongiform Encephalopathies. In humans, the disease alleged of being foodborne is the variant Creutzfeldt-Jakob disease. The human illness variant Creutzfeldt-Jakob disease and the cattle disease, bovine spongiform encephalopathy or BSE, also called as mad cow disease, seem to be triggered by the same agent. Other analogous but not identical Transmissible Spongiform Encephalopathy illnesses emerge in animals as seen by means of medical microscopy using a microscope, but there is no known transference of these Transmissible Spongiform Encephalopathies to humans. Involved among these, the chronic wasting disease of elk and deer, and the oldest recognized of these illnesses is the scrapie, which transpires in sheep and goats. No initial acute clinical symptoms for Transmissible Spongiform Encephalopathies have been illustrated. After a lengthened incubation period of years, these illnesses result in irreversible neurodegeneration as examined through medical microscopy using a microscope.

The neurodegenerative phase of variant Creutzfeldt-Jakob disease in humans normally includes the development of daisy-shaped regions of destruction in the central nervous system as viewed via medical microscopy using a microscope. There is also, in communal with other Transmissible Spongiform Encephalopathies, vacuolization or formation of holes that provides brain tissue a spongy look when examined through medical microscopy under a microscope. It is believed that the build-up of the abnormally shaped prion proteins triggers the observed neurodegeneration.
The most dependable way for diagnosing any Transmissible Spongiform Encephalopathy is the examination of brain tissue by means of medical microscopy under a microscope, which is a post-mortem process. Initial diagnoses of variant Creutzfeldt-Jakob disease are according on patient history, clinical manifestations, electroencephalograms, and magnetic resonance imaging of the brain.

The main worry for customers is the potential infection of meat products by bovine spongiform encephalopathy infected tissues or the inclusion of bovine spongiform encephalopathy infected tissues in foods, including dietary supplements. High risk tissues for bovine spongiform encephalopathy infection involve the cattle’s skull, brain, trigeminal ganglia or the nerves connected to the brain, eyes, tonsils, spinal cord, dorsal root ganglia or the nerves connected to the spinal cord, and the distal ileum, which is portion of the small intestine. The direct or indirect ingestion of high-risk tissues may have been the source of human diseases. Bovine meats provided it is free from central nervous system tissue and milk have displayed no contamination in test animals using medical microscopy. Gelatin, taken from the hides and bones of cattle, seems to be extremely low risk, specifically with sufficient attention to the quality of source material and usefulness of gelatin-making procedure. Based on numerous science research studies, science researchers have concluded that types of Creutzfeldt-Jakob disease other than variant Creutzfeldt-Jakob disease do not to be connected with the ingestion of particular foods.

Instances of variant Creutzfeldt-Jakob disease commonly present with psychiatric problems like depression. As the illness advances, neurologic symptoms manifest such as obnoxious sensations in the limbs and or face. There are difficulties with walking and muscle coordination. At times, late in the course of the illness, victims turn absentminded and then suffer from serious problems with processing information and speaking. Patients are hospitalized and are gradually more not able to care for themselves until death happens.
