Ringworm is a fungal skin infection common in housed cattle. This guide covers welfare impacts, treatment, and zoonotic risk management.
Key Facts
Ringworm in cattle is caused by Trichophyton verrucosum fungus
Characterised by circular, crusty, hairless lesions on the face and body
Young housed cattle are most commonly affected during winter
The condition is mildly irritating rather than severely painful
It is highly contagious between cattle and can spread rapidly in housed groups
Ringworm is a significant zoonosis — human infection is common
Welfare Considerations and Management
Ringworm management involves antifungal treatment of affected animals and environmental hygiene to reduce spread. Topical antifungal sprays applied to lesions and surrounding skin accelerate recovery. Most lesions self-resolve over 3-4 months without treatment. Farm workers must wear protective clothing when handling affected cattle. Human infections should be treated promptly with antifungal cream.
What You Can Do
Wear protective gloves and clothing when handling ringworm-affected cattle
Apply topical antifungal treatment to lesions to accelerate recovery
Disinfect shared equipment and housing to reduce environmental contamination
Seek medical advice promptly if humans develop circular skin lesions
