Livestock face mass mortality during European heatwaves

Extreme heatwaves in Europe are causing significant mortality among livestock. In Germany, research indicates that at least tens of thousands of farm animals died during a heatwave in late June 2026, when temperatures reached nearly 42 degrees Celsius. Poultry and pigs are particularly vulnerable because they lack sweat glands, making it difficult to regulate body temperature through evaporation.

While official nationwide statistics for heat-related animal deaths in Germany are lacking, similar crises have been reported elsewhere. In the United Kingdom, authorities estimated losses of over 17,000 animals this summer, primarily poultry. French media have also reported mass die-offs of poultry and pigs.

To mitigate heat stress, farmers are implementing various cooling measures. In the Märkischer Kreis region of Germany, farmers are using large-scale fans, water misting systems to utilize evaporative cooling, and ensuring constant access to shade and water. Managing the stable climate is critical, as different animals have varying sensitivities; for example, while older cattle require constant airflow, young calves and piglets are highly sensitive to drafts.
