A Northumberland yard, where equine infectious anaemia (EIA or swamp fever) was diagnosed in a horse in September has reopened.
One horse was euthanased and others remained under quarantine for 90 days at the premises in Ashington, Northumberland after the disease was found.
The area has been under a movement restriction since the outbreak but the restrictions were removed on Thursday 16 December.
A Defra spokesman said: “Careful checks were made after the 90-day testing deadline. None of the other horses at the premises have the infection.”
The yard belongs to horsedealer John Graham and the infected horse was in a group imported from Holland in August.
