A cull of 100 healthy sheep began on a farm in Cambridgeshire this morning.
Slaughter begins on Cambs farm
Officials from the Ministry of Agriculture moved in at dawn to begin the slaughter as part of the Government's efforts to slow down the spread of foot-and-mouth disease.
The cull was necessary because farmer Robin Anderson had taken a flock of sheep for sale at Northampton market on February 22 but had decided not to sell two underweight animals and brought them back.
Although none of his animals have shown any sign of the disease the possibility of contact with infected sheep means they must be slaughtered.
No cases of foot-and-mouth have so far been found in Cambridgeshire.
