Kosher foods are prepared in a way that follows biblical traditions which are over three thousand years old.
Most domestic poultry is also acceptable.
All meat and poultry, whether kosher or not, first undergoes a rigorous inspection by the U.S. Department of Agriculture. In addition to meeting USDA requirements, Kosher meats are processed according to the rules of one of several Kosher supervision agencies. Meat derived from these animals is then Koshered by first salting and then thoroughly rinsing to remove impurities. During processing, the meat is trimmed of certain fats, all veins and arteries. The primary difference between Kosher and non-Kosher hot dogs is that Kosher hot dogs do not contain pork.
