For the best quality, store-bought hummus first check the expiry date. The shelf life of your hummus depends on when it was made at the factory. You will need to check all the containers because the hummus shelf life might fluctuate. You will want to pick a container that has a long shelf life. The expiration time could be in a few days to a few weeks, so be sure and look for the longest expiration date. Look your container over to be sure the package is sealed well. Check that it has a normal consistency for hummus, this is a good indication that it is fresh. Some hummus packages have chopped veggies or seeds on top of the hummus or a little olive oil drizzled so don't be alarmed. It's best to give hummus with toppings a good stir before serving.
