Figure 1.

Survival of SARS-CoV-2 on deli foods. SARS-CoV-2 was recovered from foods immediately after inoculation (0 h) and at 1 h, 24 h, 7 days (d), 14 d, and 21 d after inoculation at 4 °C (n = 3). Infectious SARS-CoV-2 was quantified by plaque assay on Vero E6 cells and shown as log PFU/mL. The inoculum is shown as a solid gray line (3.9 log PFU/mL) and the detection limit of the plaque assay is shown as a dashed line (0.7 log PFU/mL). Significant differences between means are indicated by asterisks (* < 0.05; ** < 0.01; *** < 0.001).
