This site is an informational resource about boar taint, or "boar odor." It defines what it is, why it is important to continue to control and explores past and emerging solutions producers use to control boar taint to keep high quality pork available across the globe.

The traditional agricultural practice to control boar taint is physical castration of male piglets at a very early age.
