Ritz Crackers are vegan as they do not contain any ingredients derived from animals.
Unless you add cheese to the Ritz Crackers they are vegan and vegans can eat Ritz Crackers.
Ritz Crackers do contain gluten so if you have a gluten allergy then you should avoid Ritz Crackers.
Ritz Crackers do have gluten because a few of the ingredients in Ritz Crackers are Wheat and Barley.
The shelf life of Ritz Crackers is around 10 years although Ritz Crackers can start going stale after 2 years so the Ritz Crackers are best eaten within 2 years but they remain safe after that time.
Ritz crackers have a shelf life of up to 10 years as long as the Ritz crackers package stays sealed and you store them in a cool dry place such as your pantry.
Once you open the Ritz crackers package the Ritz crackers shelf life then goes down and usually only lasts around 3 to 6 months before they go stale.
So if you open the Ritz crackers make sure to eat them up within a month for the best taste but after a few months they will still be safe to eat but also they won't taste as good.
Ritz crackers here don't last long because we eat them up well before they have time to go bad because we love the Ritz crackers and I buy them every month to keep stocked up on them.
