Major investigation to find source of BSE case

The Minister for Agriculture Mary Coughlan says that a major investigation is underway into a case of mad cow disease in County Donegal.

The five-year-old cow which was infected with BSE was discovered in a Donegal herd this week.

It was born six years after tight controls were introduced to eradicate the brain disease - which can lead to variant CJD in humans.

Minister Coughlan said that every effort will be made to discover the source of the disease.
