If it worries you, when you get in with the shopping, put all the non-perishables (eg biscuits, pasta, tins etc) into a quarantine area (for me this is a carboard box in the hallway outside the kitchen door) and just leave it in there for 3 or 4 days. No need to wipe down, as the virus can't survive linger than that.
For the rest of it, wash your hands, assemble tins or bags or tupperware or whatever, and then decant your shopping - eg bread - into this fresh packaging and throw the old away, or for milk, etc, or sealed plastic containers that need to go in the fridge, soap them down and rinse them off in cold water, then put away. Remeber to wash hands when moving between outside stuff and inside, and afterwards, too.
There is very little risk at all of infection, so don't worry too much, but if it helps you, then it doesn't hurt to do it.
And remember, it's a good thing if your local area is testing, even if it means that your figures locally seem high.
