Here's a video about Smithfield and how they have failed, so far, to phase out gestation crates. The video depicts gestation crates, which confines pigs to the smallest space they can possible be squeezed into. They have no way of moving around, and often have sores and injuries as a result of their confinement. This is sad, especially when other corporations have been willing to change their practices.
I don't like ham or pork, but for those of you who like to have ham for your family Christmas meal, consider thinking about who you are buying from. Some companies have better, more humane practices than others.
