Sea Transport of Livestock: Welfare Guide
Sea transport of live animals represents some of the most challenging welfare conditions in the livestock sector — long durations, exposure to motion sickness, limited ability to respond to animal welfare emergencies, extreme temperatures, and distance from veterinary care create welfare risks that land-based transport does not.
Welfare Challenges in Sea Transport
Motion sickness is a genuine welfare concern for animals on vessels — cattle, sheep, and pigs can experience vestibular disruption from vessel motion, causing nausea, reduced feed and water intake, and distress. Animals that habitually travel poorly at sea may develop severe condition loss over long journeys. Seasickness is difficult to prevent and underrecognised as a welfare concern.
Temperature extremes are harder to manage on vessels than in road transport — particularly on long open-sea voyages through different climate zones. Livestock exported from Europe to the Middle East in summer face extreme heat stress if vessel cooling systems are inadequate or fail. Catastrophic mortality events from heat stress during sea transport have occurred and continue to occur in unregulated trades.
International Trade and Welfare Deficits
Much of the world's live animal sea trade — particularly from Australia, South America, and Europe to the Middle East, North Africa, and Asia — occurs under conditions that would not meet EU or UK welfare standards. Animals exported from countries with relatively strong welfare regulations enter trade chains where those protections cease to apply. The importer state determines the actual welfare experienced.
Welfare NGOs and government investigations have documented severe welfare failures in long-haul sea transport: animals dead on arrival, extreme overcrowding, heat stress, water deprivation, and inability of crews to care for sick animals effectively on multi-week voyages.
The Case for Replacing Live Animal Trade
Multiple welfare organisations and European institutions have argued for replacing long-distance live animal trade with chilled or frozen meat and genetic material trade — eliminating the welfare costs of live transport entirely. This transition would require investment in slaughter and chilling infrastructure in source countries and market development for processed product in destination markets.
