Sheep Mulesing — The Ongoing Debate

Mulesing — the surgical removal of skin folds around sheep's hind quarters to prevent fly strike — is one of the most controversial routine farm animal procedures in Australia.

Key Facts

Approximately 10 million Australian sheep are mulesed annually
Mulesing is performed without general anesthesia in most cases — using only topical or local anesthesia on some farms
Fly strike (blowfish larvae infestation) can kill a sheep in 24 hours — mulesing prevents it
New Zealand banned mulesing in 2018 and has moved to alternative fly strike prevention
ZQRX and other certifications require no mulesing as a condition of certification

Welfare Considerations

Mulesing causes acute pain — the procedure involves removing elliptical sections of skin to create bare scar tissue that resists fly strike. Pain assessments show significant suffering during and after the procedure without adequate analgesia. The welfare case for alternatives is strong: selective breeding for plain-bodied sheep with less skin folding, targeted application of insecticides, and improved monitoring can reduce fly strike risk without mulesing. New Zealand's successful mulesing phase-out demonstrates commercial viability. The Australian industry has been slower to transition due to economic inertia, though consumer pressure through wool certification is accelerating change.

What You Can Do

Choose wool products certified as mulesing-free by ZQRX or equivalent programs
Avoid wool from Australian sources without mulesing-free certification
Support selective breeding programs developing fly-strike resistant sheep breeds
Advocate for New Zealand's mulesing-free model as the standard for Australian wool
Engage fashion and outdoor brands about their wool sourcing and mulesing policies
