Think it's Haemonchus? Don't panic-test first to be sure

SCOPS (Sustainable Control of Parasites in Sheep) is encouraging farmers and the wider sheep industry to stay alert and informed as Haemonchus contortus - commonly known as Barber’s Pole worm - gains more attention across the UK

- 

While recent reports and testing suggest increased interest and possible cases of haemonchosis (disease associated with Haemonchus infections) appearing further north across the country, the reasons aren't fully understood yet. Climate change with warmer winter temperatures may allow the parasite to survive on pasture and drier, warmer springs create ideal conditions for it to take hold earlier in the spring. SCOPS stresses the importance of accurate diagnosis and calm, evidence-based decision-making to support effective parasite control on farm.

"While Haemonchus can cause serious issues in flocks, it's important that you do not panic," says Nerys Wright, SCOPS Technical Adviser. "We're seeing more interest and investigation into this parasite, which is positive, but we must avoid jumping to conclusions or reverting to blanket treatments especially in adult ewes that could undermine responsible and sustainable parasite control." What is Haemonchus contortus?

• Haemonchus is one of a number of different roundworms that are found in sheep in the UK.

Unlike many other roundworms, it does not typically cause diarrhoea.

It is a blood-sucking roundworm that resides in the stomach of sheep.
