D-values with 99% CI and times needed for a 12-log10 reduction in H7N1 HPAIV, based on the upper 99% CI, and in ϕ6 phage and MS2 phage in compost material consisting of manure, straw, and embryonated eggs (mixture 2) treated at various temperatures
| Temp (°C) | Virus or phage | D-value (99% CI) | Time to 12-log10 reduction |
|---|---|---|---|
| 35 | HPAIV | 0.39 h (0.28–0.63) | 7.6 h |
| ϕ6 | 0.17 h (0.10–0.44) | 5.3 h | |
| MS2 | NIa | ||
| 45 | HPAIV | 7.2 min (4.2–49.2) | 9.8 h |
| ϕ6 | 6.6 min (5.4–10.2) | 2.0 h | |
| MS2 | 2.6 days (2.3–2.9) | 34.8 days | |
| 55 | HPAIV | 2.5 minb | 30 min |
| ϕ6 | 1.2 minb | 14.4 min | |
| MS2 | 1.2 days (1.0–1.4) | 16.8 days |
a
NI, not included due to the estimated D-value exceeding the study period.
b
99% CI was not calculated due to insufficient data.
