Bear bile farming involves invasive catheter insertion into bile ducts causing chronic pain, with humane alternatives making the practice unnecessary.
Bear bile farming causes some of the most severe sustained suffering documented in any farmed animal. Bears kept in cages too small to stand up in, with infected abdominal catheters causing constant pain, show behaviors consistent with profound psychological and physical suffering. The justification — that bear bile has unique medicinal value — has been undermined by the availability of equally effective synthetic and plant-based alternatives. The welfare case for ending bear bile farming is among the clearest in animal welfare science.
