Frequently Asked Questions
What's the difference between expiration and best quality dates for Unopened String Cheese?
The expiration date on string cheese indicates the date until which the product is guaranteed to be at its peak quality in terms of taste and texture.

It is best to consume string cheese before the expiration date for the best culinary experience.
How can I tell if Unopened String Cheese has gone bad?

Unopened string cheese, being a dairy product, can be susceptible to contamination by harmful bacteria such as Listeria monocytogenes if stored improperly.
