According to the ingredient list for Kirkland Signature Beef Hot Dogs, they contain sodium nitrite, a synthetic preservative. While the food court hotdogs share many similarities with the packaged variety, they also use sodium nitrite for preservation. This differs from 'uncured' hotdogs, which rely on naturally occurring nitrates from sources like celery powder.

Costco's own Kirkland Signature hotdogs are explicitly labeled as gluten-free on their packaging, which suggests they are safe for many. However, for those with celiac disease or severe gluten intolerance, the question, "Do Costco hotdogs have gluten?" is far more complex when considering the food court experience.
