Farm Sheep Mulesing Welfare and Alternatives

Mulesing is a controversial surgical procedure performed on Merino sheep to prevent flystrike, causing acute pain while addressing a genuine welfare threat — and alternatives are increasingly available.

Key Facts

Mulesing involves surgically removing skin folds around the hindquarters of Merino lambs, typically without analgesia
The procedure is intended to prevent flystrike, where blowfly larvae infest wool folds and cause severe tissue damage
Flystrike causes intense suffering — untreated cases can kill sheep within days from bacterial infection and tissue destruction
Australia is the largest Merino producer and has been the center of debate over mulesing since the early 2000s
Major wool buyers including Patagonia and H&M committed to phasing out mulesing-derived wool, driving industry pressure
Pain relief during mulesing is now increasingly available and used, including local anesthetic and NSAID sprays
Alternatives include selective breeding for bare-breech sheep, chemical treatments, and wool clipping to reduce flystrike risk

Welfare Considerations

Mulesing presents a genuine welfare dilemma: the procedure causes acute pain, but flystrike causes severe suffering that mulesing prevents. The welfare-optimal solution is to develop and adopt alternatives — selective breeding for low-wrinkle sheep, combined with pain relief during any necessary procedures in the interim. The industry has made progress but pace is inconsistent. Consumer and retailer pressure has been one of the most effective drivers of change, as wool buyers setting sourcing requirements create market incentives for faster adoption of alternatives and mandatory pain relief.

What You Can Do

Support wool and apparel brands that require mulesing-free wool or mandatory pain relief during mulesing from suppliers
Look for the ZQ or Responsible Wool Standard certification on wool products which address mulesing welfare
Advocate for mandatory pain relief during mulesing as a minimum standard while alternatives are developed
Support research into selective breeding for low-wrinkle Merino sheep that eliminates the need for mulesing
Ask wool retailers about their sourcing policies on mulesing and encourage transparency about the transition timelines
