Do beef bouillon cubes expire or cause expiration?
Bouillon cubes can last for quite a while. Thirty years may be pushing that limit, though, as they lose flavor over time. Typically, they are good to use for a year maybe two; that depends on how they were stored, though. If they were in a dry cool place, they should be fine for while. They are loaded with fat and salt which are natural preservatives, anyway. Although dying is unlikely, it is definitely possible to get sick.
