The transport of live animals across long distances is among the most welfare-compromising practices in modern food systems, causing stress, injury, illness, and death to billions of animals annually.
Long-distance livestock transport causes progressive welfare deterioration through multiple pathways. Animals experience acute fear and stress responses during loading that persist throughout the journey. Mixing unfamiliar animals triggers aggression and social stress. Overcrowded vehicle conditions cause thermal stress, particularly dangerous for poultry in warm weather. Access to water is often inadequate or absent during legal maximum journey durations. Physical injuries from falls, crushing, and aggression accumulate over journey time. Sea voyages pose particularly severe welfare risks, as evidenced by multiple disasters including the 2020 Gulf Livestock 1 sinking that killed approximately 6,000 cattle and 40 crew. Reducing transport journey durations and transitioning to carcass trade rather than live animal trade would substantially reduce this welfare burden.
