The shelf life for these products are typically 36 months (3 years) from when they are packaged - which is reflected on the date printed on each product. This is an estimated time frame, as spices generally do not go bad if they are stored properly - a cool, dry place is ideal. They may lose their potency slightly, but are safe to consume. Also to be noted as a general rule of thumb is that whole spices typically last longer than ground.
We do not use any preservatives, nor do we use irradiation to extend the shelf life.
