Buy dry or block ice in case the power is out for longer than expected. About 50 pounds of dry ice will keep a fully stocked 18-cubic-feet freezer cold for up to two days.
And to prevent cross contamination, place your meats and poultry on one side of the freezer and your thawing juices on the other.
What should I do if my home is flooded?
You should not eat any food that comes in contact with floodwaters. This includes raw fruits and veggies, milk and eggs. Get rid of any food that is not stored in a waterproof container even if you think it has not come in contact with floodwaters. That goes for items packaged with plastic wrap, cardboard, screw‐caps, snap lids, pull tops and crimped caps.
Check for damaged cans too. Discard any can that has swelling, leakage, punctures, holes, fractures, extensive deep rusting or crushing that prevents normal stacking or opening with a manual, wheel‐type can opener.
When the storm is over, how do I know what to toss?
You will need to check the temperature of your fridge and freezer. Throw away any perishable foods that have been above 40 degrees Fahrenheit for two hours or more.
Inspect everything separately, and thrash anything with an unusual smell, color, texture or anything that is warm to the touch.
As for things in your freezer, you can refreeze them if the food still contains ice crystals or is 40 degrees Fahrenheit or below.
Never taste anything to determine if it is safe. “When it doubt, throw it out.”
