| Time (h) | Log10 reduction (mean ± SD) |

|---|---|---|---|
| Control | 2.0% (vol/vol) allspice | 4.0% (vol/vol) allspice | |
| 0.5 | 0.22 ± 0.2 | 0.22c ± 0.3 | 1.39b,c ± 0.4 |
| 6 | 0.28 ± 0.3 | 0.67c ± 0.2 | 1.83b,c ± 0.1 |

a
Results shown are the log10 reductions in cell culture infectivity of murine norovirus (initial titer, 4.21 × 106 TCID50/ml) after various time exposures to allspice oil 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.
c
Reductions were significantly different (P ≤ 0.05) between 2.0% and 4.0% allspice oil.
