SARS-CoV-2 persistence on common food covering materials: plastic wrap, fruit wax, and cardboard takeout containers.

Aims: Assess the persistence of infectious SARS-CoV-2 virus and virus genomic material on three common food coverings.

Methods And Results: The stability of infectious virus and genomic material on plastic wrap, fruit wax, and cardboard takeout containers was measured. SARS-CoV-2 in simulated saliva was applied to the surface of these materials and allowed to dry.

Decontamination of SARS-CoV-2 contaminated N95 filtering facepiece respirators using artificial sun lamps.

Aims: Assess the feasibility of using light from artificial sun lamps to decontaminate N95 filtering facepiece respirators (FFRs) contaminated with SARS-CoV-2.

Methods And Results: FFR coupons or whole FFRs contaminated with 5 log TCID (target concentration) SARS-CoV-2 in culture media, simulated saliva, or simulated lung fluid were dried for 1-2 h, then exposed to light from tanning and horticulture lamps to assess decontamination. Exposed coupons and whole FFRs showed SARS-CoV-2 inactivation for all matrices tested.
