Foie gras is produced by force-feeding ducks or geese to enlarge their livers. It is banned in over 20 countries and remains deeply contested in others. Understanding the welfare evidence helps consumers and policymakers make informed choices.
The welfare evidence against conventional foie gras production is strong and largely uncontested outside the industry. Force-feeding multiple times daily causes physical injury to the esophagus, respiratory difficulty from abdominal pressure on the air sacs, impaired mobility, and the metabolic stress of induced liver disease. The comparison to pre-migratory gorging in wild ducks is scientifically contested — wild hyperphagia is voluntary, progressive, and physiologically prepared for. In gavage production, the process is forced, repeated, and concentrated. Countries that have reviewed the evidence have consistently concluded that foie gras production causes unnecessary suffering. Consumer avoidance of foie gras is one of the most direct food choices available to reduce a specific, severe welfare harm.
