Scrapie – what you need to know

Find essential information on scrapie and how you can help Defra monitor for the disease.

Scrapie is a notifiable and fatal brain disease that affects sheep and goats.

Signs and symptoms

There are two types of scrapie – classical scrapie and atypical scrapie.

Classical scrapie is highly contagious and usually affects animals aged between 2 and 5 years old. It can be spread via colostrum and milk, and via contaminated animals and what they come into contact with, including pastures where animals have given birth. 

Atypical scrapie usually involves animals older than 5 and is believed to not be very contagious or potentially not contagious at all.

The name scrapie refers to the compulsive behaviour displayed by affected animals who may repeatedly rub against objects and nibble at their body to relieve irritated skin.

Affected animals may also act differently (excitable, nervous, aggressive, depressed), display drooping ears and lag behind the herd. It can also affect their gait and their strength, causing trembling (this usually affects the head) and an overall lack of coordination and weakness, including the inability to stand. Weight loss is a late clinical sign.

Help protect the national flock

Livestock producers are being reminded to arrange fallen stock collection to contribute to Defra’s annual scrapie surveillance to help meet targets.

While Defra covers the cost of sampling and testing, keepers pay for collection and disposal, as usual.

Reporting suspected cases of scrapie

Scrapie is a notifiable disease. Suspected cases of scrapie must be reported immediately. Failure to do so is an offence.

Detection of a positive case of atypical scrapie no longer triggers APHA restrictions on a holding. 

Scrapie surveillance

Measures for the prevention, control and eradication of TSEs (Transmissible Spongiform Encephalopathies) including scrapie are required by law.

Testing is carried out on around 15,000 randomly selected fallen sheep and 500 goats per year across Great Britain.

Fallen stock over 18 months old is tested alongside a sample of nearly 5,000 healthy sheep that have been sent for slaughter.

The survey provides valuable insight into the distribution, causes and control of the disease within populations.

While the decline in classical scrapie cases in recent years highlights the progress made in disease control and management, industry support remains critical in maintaining robust surveillance and important trade and export markets.
