"What exactly is in a hot dog?
The ingredients in hot dogs have been the subject of much humor, rumor and speculation. But the answer is less exciting than the question.
All hot dogs are cured and cooked sausages that consist of mainly pork, beef, chicken and turkey or a combination of meat and poultry. Meats used in hot dogs come from the muscle of the animal and looks much like what you buy in the grocer's case. Other ingredients include water, curing agents and spices, such as garlic, salt, sugar, ground mustard, nutmeg, coriander and white pepper.
If variety meats such as liver and hearts are used in processed meats, the U.S. Department of Agriculture requires the manufacturer to declare those ingredients on the package with the statement "with variety meats" or "with meat by-products." The manufacturer must then specify which variety meat is included. In the U.S., companies are required to list ingredients in order, from the main ingredient, to the least ingredient."
