We set a cooler on the back patio...groceries that require refrigeration go into the cooler for 72 hour before bringing inside. All other groceries are left in the car for 72 hours until we bring them inside. If we need something before the 72 hours, we sanitize. Maybe its overkill?
The stress of our first grocery run is what pushed us to do this. Handling everything, items sitting on the kitchen floor and on the counter, then touching the fridge handles and pantry cabinet we realized we had to sanitize all kinds of items and surfaces when we were done...Waiting 72 hour just offers a little peace of mind.
