Oak processionary moth threatens public health in Germany

The oak processionary moth (Thaumetopoea processione) has become a growing concern in Germany. Its caterpillars feed on oak leaves and are covered with urticating hairs that contain the toxin thaumetoporin. Contact with these hairs can cause skin irritation, allergic reactions, eye irritation, respiratory problems, dizziness and fever. Health authorities such as the Naturschutzbund Deutschland (NABU) and the Umweltbundesamt advise anyone exposed to avoid touching the eyes, wash skin and clothing at at least 60 °C, and use antihistamines or anti‑inflammatory creams. In severe cases, affected eyes should be flushed with water. Recent sightings in Hahnbach prompted local authorities to cordon off affected oaks and warn residents of the health risks.
