Girl Eating Hot Dog

Unlike other sausages which may be sold uncooked, hot dogs are precooked before packaging. Hot dogs can be eaten without additional cooking, although they are usually warmed before serving. Since even the unopened packaged hot dog can have bacteria it is safer to reheat them, which is especially important for pregnant women and those with suppressed immune systems.
Claims about hot dog invention are difficult to assess, as stories assert the creation of the sausage, the placing of the sausage (or another kind of sausage) on bread or a bun as finger food, the popularization of the existing dish, or the application of the name "hot dog" to a sausage and bun combination most commonly used with ketchup or mustard and sometimes relish.
