A case of anthrax has been discovered in a cow in Wiltshire - the first case in an animal since 2006.
There are restrictions on the farm at Westbury. The cow has been incinerated.
It has been confirmed that no cattle from the field have entered the food chain. A local footpath has been closed. Wiltshire Council is taking "swift action" to deal with the case, saying it is working with partners locally and nationally.
Anthrax is caused by the organism Bacillus anthracis, which can be found in cattle or other hoofed mammals.
A man died in 2006 in Scotland from the disease, which was believed to be the first case for 20 years.
There are fears that heroin contaminated with anthrax is being distributed around Oxfordshire.
The Health Protection Agency says one person has already been diagnosed with the infection. That person is now recovering, but others are being urged to be aware of the symptoms. Kate Bunkall reports.
The Health Protection Agency (HPA) is aware that a person who injected heroin has been diagnosed with anthrax infection in Oxford. The patient is recovering.
This case has occurred after two drug users died from confirmed anthrax infection in Blackpool within a month of each other earlier this year.
There is an ongoing outbreak of anthrax among people who inject drugs in a number of countries in Europe with 12 cases now identified since early June.
The latest case in Oxford brings the total number affected in the UK to five. The source is presumed to be contaminated heroin.
It is unclear whether these cases are linked to others in Europe (four in Germany, two in Denmark, one in France) but the HPA is continuing to monitor the situation.
The European Centre for Disease Prevention and Control (ECDC) have concluded that heroin users in Europe are still at risk of exposure.
