How to tell if wax beans are bad
Smell
Fermented, sour or musty odour.

Wax beans past the expiration date
Best-by and sell-by
FoodKeeper gives unopened wax beans 3–5 days in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
Wax beans past their best-by date are usually safe if stored well; check smell, look and taste before using.
How to keep wax beans fresh longer
- Store unwashed; wash just before eating.
- Keep ethylene producers (apples, bananas, avocados) away from produce that over-ripens.
- Refrigerate once cut, in a covered container.
