South Korea has reissued its ban on U.S. beef, citing a disagreement on importation and health safety codes. According to South Korean officials, inspectors also found a piece of cow bone in the beef; South Korean agriculture authorities have banned the importation of beef bones over fears of mad cow disease.

South Korea, which used to be the third largest market for U.S. beef, suspended importing U.S. beef in 2003. It lifted the import ban last year but imposed it again in August this year

A promising new vaccine could one day cause fears of the human version of mad cow disease to melt away like the fat on a well-marbled T-bone steak broiling on a hot grill. That is, of course, if scientists can find a way to develop a vaccine for humans that works as well as one made for mice.

In a new study, researchers at New York University found mice that were given an oral vaccine developed high antibody titers to the prion proteins similar to that in cattle with BSE. The mice had no symptoms more than 400 days after being exposed to the infectious prion disease scrapie

The Canadian Food Inspection Agency has reportedly confirmed the country's 10th case of mad cow disease since 2003. The diseased dairy cow was found in the western province of British Columbia.

Authorities on Wednesday confirmed that no part of the animal entered the human food or animal feed systems and its carcass is under CFIA control. According to preliminary information, the agency is speculating that the 5 1/2-year-old cow was infected during its first year of life

The Canadian Food Inspection Agency has detected a new case of mad cow disease in a bull at Alberta, Canada under the national Bovine spongiform encephalopathy (BSE) surveillance program. Though this is the ninth case of mad cow in the country since May 2003, the authorities have confirmed that none of the animal has entered the food chain yet. All the animals are believed to have contracted the disease from contaminated feed.

BSE - commonly known as mad cow disease, is a fatal disease that causes progressive neurological degeneration in cattle. Similar to BSE, Creutzfeldt-Jakob disease (CJD) is a rare disease that occurs in humans. In 1996, following outbreaks of BSE among British cattle, scientists found a possible link between BSE and a new variant of CJD (vCJD). While it is not certain how BSE may be spread to humans, evidence indicates that humans may acquire vCJD after consuming BSE-contaminated cattle products

Researchers across the United States have reportedly found a way to tackle the Mad Cow disease by genetically engineered cattle. These cattle have immunity against bovine spongiform encephalopathy (BSE), or Mad Cow disease, thus helping eliminate the disease if consumers are ready to accept genetically engineered cattle.

Bovine spongiform encephalopathy (BSE) commonly known as mad cow disease, is a fatal, neurodegenerative disease of cattle. It also adversely affected the country's agriculture industry as many countries banned the imports of cattle from U.S. due to this disease
