Bear bile farming confines Asiatic black bears in tiny cages for decades to extract bile used in traditional medicine, representing one of the most severe documented animal welfare crises.
Bears on bile farms develop severe physical pathologies from their conditions: severe muscle atrophy from inability to move, dental problems from cage bar gnawing, chronic infections from bile extraction wounds, and liver pathology from the extraction process itself. Psychological distress manifests as stereotypic head-weaving, self-mutilation, and extreme responses to human approach. Bears that have been farmed for years require extensive rehabilitation before they can experience quality of life in sanctuary environments. The welfare crisis on bile farms is among the most severe documented for any captive species.
