Foie gras production through force-feeding (gavage) of geese and ducks causes severe welfare harm; production is banned in many countries.
The welfare case against foie gras production is among the most clear-cut in farm animal welfare. Repeated gavage of a metal feeding tube causes oesophageal trauma, chronic stress, and progressive physiological deterioration as the liver becomes pathologically enlarged. Birds in the final stages of force-feeding show laboured breathing, reluctance to move, and are clearly in distress. The product is the result of induced disease — the enlarged liver represents a pathological state, not enhanced quality. Consumer rejection of foie gras is the primary mechanism for reducing production and imports to non-producing countries. Import bans in countries where production is illegal would provide stronger consumer protection.
