Table 2.
log reductions of SARS-CoV-2 (TCID50/g) on berries stored at different temperatures for various time points. Comparing within berries: means with different letters differ significantly (p < 0.05). Comparing between berries: significant differences are denoted with asterisks when p value < 0.05. Data were expressed as mean ± standard error (SE).
