Carnivore Snaxs are best enjoyed within 3 days after opening. We recommend refrigeration after 3 days in order to preserve the integrity of their awesome texture. Consume Carnivore Snax within 10 days after opening. Unopened bags are good for 6 months (if they last that long!). These are preliminary shelf-life tests. Carnivore Snax can also be frozen if you're going away or unable to consume right away - we do have some customers who freeze them.
