This could be difficult if you live in an apartment or a small area, but if you're able, try to unpack your groceries in your garage or the entryway of the house, so you're not bringing germs any farther into your house than necessary. It's not a bad idea to wear gloves while unloading the groceries in the garage and disposing of all unnecessary packageing there. Then transport the food into your kitchen in a clean container and finish sanitizing everything.
