Introduction
The summer of 2025 was the hottest on record in the UK, and this increase in temperatures had a devastating impact on livestock being transported to slaughterhouses. According to a recent analysis, the number of livestock deaths due to heat stress during transportation more than doubled compared to the summer of 2024.
Heat-Related Deaths
Data obtained through the UK's Freedom of Information (FOI) Act shows that 6,595 animals died due to heat stress during transportation to slaughterhouses between June and August 2025. This represents a significant increase from the summer of 2024, when 3,100 animals died due to heat.
The most severe incidents occurred during heatwaves, with nearly 1,000 chickens dying in a single day during a heatwave on July 11, 2025. On August 12, 2,154 chickens died due to heat stress, with some of their body temperatures reaching 46°C.
Preventing Deaths
To prevent these deaths, it is essential that livestock transporters take measures to protect animals from heat stress. This includes ensuring that ventilation and cooling systems function properly, avoiding travel during the hottest parts of the day, and recognizing signs of heat stress in animals.
Furthermore, it is crucial that governments and agricultural industries work together to develop and implement sustainable policies and practices that prioritize animal welfare and food safety.
Cold-Related Deaths
In addition to heat-related deaths, livestock are also susceptible to cold-related deaths. According to the data, 13,057 animals died due to cold weather between December 2024 and February 2025, more than double the number of deaths in the previous winter.
It is essential that livestock transporters are prepared to handle extreme weather conditions and take measures to protect animals from the cold, such as providing adequate shelter and food.
Conclusion
Livestock deaths due to heat stress during transportation are a serious issue that requires immediate attention. It is essential that governments, agricultural industries, and livestock transporters work together to develop and implement sustainable policies and practices that prioritize animal welfare and food safety.
Additionally, it is important that consumers are aware of these issues and make informed choices when purchasing agricultural products. Together, we can work to reduce the number of livestock deaths due to heat stress and promote more sustainable agricultural practices.
