Sheep Scab Control and Welfare

Sheep scab, caused by the Psoroptes ovis mite, causes intense pruritus and welfare compromise. Effective control requires coordinated community action.

Key Facts

Sheep scab was eradicated from the UK in 1952 but re-emerged after dipping regulations changed
Infestation causes intense itching, fleece loss, and body condition deterioration
Untreated animals develop skin thickening and may die from secondary infection
Treatment options include injectable macrocyclic lactones and organophosphate dipping
Effective control requires biosecurity and coordinated treatment at community level

Welfare Considerations

Sheep scab causes severe, persistent pruritus that significantly reduces welfare. Affected sheep bite and rub constantly, causing fleece loss and skin damage. The welfare case for effective, sustained control programmes is strong. Both injectable and dip treatments are effective, but resistance management is important to maintain efficacy.

What You Can Do

Report suspected scab to your vet or the Animal Plant Health Agency
Support biosecurity measures in your area to prevent scab re-introduction
Advocate for coordinated community-level scab control in high-risk areas
