If you open your order and there is no dry ice left, look at your meals--if they arrived frozen, partially frozen, or cold to the touch (as if you had just taken it out of the refrigerator)--then they're safe to eat per USDA guidelines. Simply place the meals in your freezer to refreeze and when ready to eat, follow the cooking instructions on each product's packaging. Please note that once a shipment of meals has been opened, the temperature of the meal packaging will increase much faster than the actual temperature of the food. If in doubt, remove the product packaging and inspect each meal individually to determine if it remains safe.
