I was wondering the same thing about sanitizing a store. More importantly, what about the hands opening boxes, taking product out and stocking the shelves? Are they all gloved? How often are gloves changed? How are they doffed and discarded?
I figure you bring things home, put on gloves, put your groceries away. I think they have a list somewhere that tells you how long the virus lives on inanimate objects. Wipe down anything plastic with wipes (or Lysol), don’t save the plastic bags just throw them away.
