If you go to any place and you can physically see where those spit barriers have not been cleaned. Turn around right away. There’s a White Castle I went to where bacteria growth had started taking place and now that a lot of customers aren’t coming inside: even basic cleaning like mopping have stopped. If I were a scientist and could prove my theory. I would say Covid has made into our food supply chain and is spreading non traditionally. While we’re oh so caught up in wearing masks: we are also ingesting in our foods and drink and in some cases through our eyes. Your best bet is to stay home order groceries delivered cut the bags open on the porch leave the bags outside and take your food only inside.
