Best option is to buy local.  Visit your local farmers market, they typically have fresh meat or know where you can go to get it. 

Also slaughterhouse is not the correct term as all animals end up there; that is the term used for where animals are killed and hung and then butchered.

Talk to Lyme, she just recently bought a half cow if I remember correctly.  She also just had her first "organic" beef (I used quotes because organic is not a typical term for animals).
