a
If only one value is reported, that value is marked as the mean value. VpV, V. parahaemolyticus virus.
b
Rates correspond to published observations at the minimum, mean, and maximum temperatures listed for this study.
c
These temperatures (4.0/9.4°C) are usually reported as bacteriostatic for V. parahaemolyticus.
d
The reported rate of 0.33 day−1 was at a temperature of 15°C instead of the corresponding 14°C in this study.
e
BC, British Columbia, Canada; FL/HI, Florida and Hawaii; NW, Northwest; US, United States; JP, Japan.
