How to spot African swine fever, what to do if you suspect it and measures to prevent its spread.
African swine fever affects pigs.
It doesn’t affect humans.
There has never been an outbreak of African swine fever in Great Britain.
African swine fever is a notifiable animal disease. If you suspect it you must report it immediately by calling the Defra Rural Services Helpline on 03000 200 301. Failure to do so is an offence.
How to spot African swine fever
The signs of African swine fever are very similar to classical swine fever.
The main clinical signs are:
- loss of appetite
- lack of energy
- sudden death with few signs beforehand
Other signs can include:
- red or dark skin, particularly on the ears and snout
- swollen red eyes
- laboured breathing and coughing
- abortions, still-births and weak litters
There are several different strains of African swine fever.
Pigs infected with mild strains may not become ill or show typical clinical signs.
Severe strains of the disease are generally fatal.
How African swine fever is spread
The disease is highly contagious. It can spread by:
- pigs eating infectious meat or meat products
- contact with infected pigs or their faeces or body fluids
- contact with anything contaminated with the virus including:
- people and their clothing
- vehicles and other equipment
Preventing and controlling African swine fever
You can help prevent the disease by practising strict biosecurity on your premises.
If you report suspicion of African swine fever, APHA vets will investigate.
If African swine fever is confirmed, it will be controlled in line with the contingency plan for exotic notifiable diseases and the African swine fever disease control strategy for Great Britain.
