Joint statement of the US FDA and USDA:
there is no credible evidence of food or food packaging associated with or as a likely source of viral transmission of severe acute respiratory syndrome coronavirus
Of course, the wipe down theater will continue.
Related: It seems acknowledged now that transmission has been mostly via airborne aerosols. This explains the work place outbreaks where, say, 90 people in a hospital ER, all wearing PPE, contracted Covid-19 simultaneously. They did not have direct droplet hits on all of them. Austria, Germany, the White House and the NBA have banned cloth masks, and now mandate N95 equivalent masks. France and the EU’s CDC equivalent now recommend using medical-grade masks only and OHSA may mandate N95 masks for certain U.S. workers as soon as March 15. Their actions say they see aerosolized spread as primary and cloth masks as ineffective since day #1.
