You can ship food with dry ice as long as it's in a cooler such as a sealed Styrofoam cooler.
Omaha Steaks are food that comes shipped with dry ice to keep the Omaha Steaks frozen.
Omaha Steaks last around 36 hours in dry ice.
By the time the Omaha steaks get to your door the dry ice is usually either partially melted or no longer in the cooler with the Omaha Steaks.
The Omaha Steaks should be frozen as soon as you get them so they won't spoil.
Omaha Steaks are shipped in dry ice and frozen to ensure they remain safe during shipment.
Omaha Steaks says they expect there to be little or no ice left in each cooler when they arrive but the Omaha Steaks are still frozen.
I've found this to be true with the Omaha Steaks I buy.
The steaks are still frozen but the dry ice is nearly gone or gone fully.
I immediately either set some of the steaks aside to cook or if not cooking the steaks right away I place them in the freezer.
