Celery salt is an ingredient of the Bloody Mary cocktail and the Caesar cocktail.^[6] It is also reported to be an ingredient in KFC's secret spice mix.^[7] It is also commonly used to season the Chicago-style hot dog, the New York System wiener, salads, coleslaw and stews. It is a primary ingredient in Old Bay brand seasoning.^[8]

Because sodium nitrate, a chemical that serves as a food preservative, occurs naturally in celery, celery salt is often used by food producers to prevent spoilage while avoiding listing sodium nitrate on the ingredients list directly.^{[9][citation needed]}.
