THE world's oldest breed of cattle is under threat of being wiped out by foot-and-mouth.

A new case at Millfield, Northumberland, spells danger for the Chillingham herd, which roam in parkland only ten miles away.

The herd, which has been bred for more than 700 years, narrowly survived the last outbreak in 1967.

The 48-strong herd could succumb if the highly contagious virus spreads to the 300 acres of Chillingham Park.

Keeper Austin Widows fears for their safety.

He said: "They are still in their park, which is surrounded by forest and a wall, so they are far less at risk than commercial cattle.

"The herd are more resistant to disease than commercial cattle - but foot-and-mouth is obviously a big worry."

In 1967, farms only two miles away from the estate were affected.

Contamination of any of the cattle would result in the whole herd being destroyed and the species becoming extinct.

Mr Widows said: "This is such an ancient and important breed that we must take every measure possible to keep them safe."
