Sea transport of live animalsāprimarily cattle and sheep transported on large livestock vessels from Australia, South America, and Europe to Middle Eastern and North African marketsārepresents some of the most severe and prolonged animal welfare experiences in global trade. Journeys lasting weeks combine extreme heat, high stocking density, disease, and mortality in ways that have attracted sustained welfare concern.
Australian live export of sheep and cattle has involved documented mortality events during summer voyages through the Middle East: heat stress deaths, salmonellosis outbreaks, and respiratory disease in high-density conditions. Australian government inquiries documented systemic welfare failures across multiple voyages. The footage of suffering animals that emerged drove significant public and political pressure on the industry.
Stocking density: Insufficient space prevents normal lying and movement. International guidelines set minimum space allowances but compliance and enforcement have been inconsistent. Thermal environment: Summer voyages through tropical waters generate heat loads that exceed cattle and sheep thermoregulatory capacity. Ventilation systems have been inadequate on some vessels. Disease: Bovine and ovine respiratory disease spreads rapidly in high-density, stressed populations. Feed and water: Ensuring adequate access for all animals when feed is provided at specific times and locations is challenging with high stocking densities.
Australia's Live Export Reform process culminated in a phase-out of live sheep export by 2028. Improved regulatory oversight, stricter heat stress standards, and enhanced veterinary inspection have reduced mortality rates in the short term. The fundamental welfare question of whether sea transport over weeks can ever be welfare-acceptable for large mammals remains contested.
