Food shortages should be anticipated, but even if there were plenty of groceries on the store shelves, during a pandemic you would want to avoid close contact with others, so going to a grocery store might pose an unacceptable health risk to you. Consider that you could physically distance yourself from others and dress appropriately, wearing an N100 respirator and Nitrile gloves while shopping, yet the possibility exists that you will unknowingly bring the flu virus home from the market. It could be on your groceries. This is because humans handled the items in your grocery bags, and in a severe pandemic at least 33% of those humans will eventually get the flu. Influenza virus can easily survive on the exterior of a package for 48 hours or more, you would be compelled to sanitize or quarantine everything you bought before bringing it into your home.
