Classical swine fever: how to spot and report the disease
How to spot classical swine fever, what to do if you suspect it, and measures to prevent its spread.
Classical swine fever affects pigs.
It is not known to affect humans.
The last outbreak in Great Britain was in 2000.
Classical swine fever should not be confused with swine flu which is a different disease.
Classical swine fever is a notifiable disease. That means if you suspect it you must tell the Animal and Plant Health Agency (APHA) immediately. Failure to do so is an offence.
How to spot classical swine fever
The signs of classical swine fever are very similar to African 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
- nervous signs, eg convulsions and tremors in newborn piglets
There are several different strains of classical swine fever.
Pigs infected with mild strains may not become ill or show clinical signs.
Severe strains of the disease are generally fatal.
How classical swine fever is spread
Classical swine fever is very contagious. It can spread by:
- pigs eating infectious meat or meat products
- contact with infected pigs or their faeces or body fluids
- contact from infected sows to their piglets
- contact with anything contaminated with the virus including:
- people and their clothing
- vehicles and other equipment
