The answer to that is yes you can do that but it’s not necessary.
Should I Wash My Groceries with soap and water?
Yes. Instead of leaving them outside, you can wipe down all the bags and boxes with soap and water.
Also wipe the floor where the groceries where with soap and water as well.
When you are at the grocery store, make sure you’re wiping down the shopping cart handle and stay six feet away from people. Of course wear a mask to keep safe.
And try to get everything you need for a while. The less you have to go to the grocery story, the less likely you are to get coronavirus.
