Antimicrobial efficacy of citrala
| Time (h) | Log10 reduction (mean ± SD) |

|---|---|---|---|
| Control | 2.0% (vol/vol) citral | 4.0% (vol/vol) citral | |
| 0.5 | 0.15 ± 0.3 | 0.67 ± 0.3 | 0.70 ± 0.4 |
| 6 | 0.05 ± 0.1 | 1.40b ± 0.5 | 1.88b ± 1.1 |

a
Results shown are the log10 reductions in cell culture infectivity of murine norovirus (initial titer, 1.79 × 106 TCID50/ml) after various time exposures to citral at two concentrations. The experiment was conducted in triplicate.
b
Reduction was statistically significant (P ≤ 0.05) in comparison to the control (with no antimicrobials) at the same time exposure.
