We ship ALL frozen packages with Dry Ice. Dry Ice is unique in that it goes from a solid (ice) to a gas (carbon dioxide) without ever becoming a liquid. This process is called sublimation, and it makes dry ice perfect for shipping frozen foods. We add the optimal amount of dry ice to get your shipment to you in good condition. It is very likely that the dry ice will have sublimated by the time the package arrives. As long as the steaks are “mostly frozen” they are perfectly safe to consume and it is fine to store steaks in the freezer for up to 1 year or until you are ready to enjoy them. NEVER touch residual dry ice with bare skin, as it will cause instant freezer burn!!
