Kashruth What makes kosher bison, kosher? First, all of our Solomon's Glatt Kosher bison are raised naturally, with no antibiotics or artificial hormones. Only young healthy bison, who show no evidence of disease or illness, are selected by skillful professional shochtim and then each animal is checked according to strict Jewish Law (Halacha) as well as by USDA inspectors, to ensure healthfulness and purity. Only healthy bison, certified by the OU - are sold by our company. All of the bison sold by KosherBison.com meets the criterion of 'halak Beit Yosef', the very highest standard of kashruth. Handling Kashruth doesn't end with slaughter. Kosher meat must be soaked and salted according to Jewish Law within 72 hours after slaughter. Our glatt kosher bison products are all soaked and salted and then chilled and shipped fresh (in most cases) or frozen, and packed with blue ice. Purity, Cleanliness and Kashruth are the hallmarks of every KosherBison.com product.
