Sensitivity and specificity of the NMKL71 (RVS), MSRV and EN ISO 6579:2002 (RVS + MKTTn) methods at different spiking levels of Salmonella.
| Selective medium | Specificity (%) | Sensitivity (%) | |||
| cfu/25 g of Salmonella | |||||
| 0 | 0–1 | 1–10 | 10-102 | 102–103 | |
| RVS | > 97 | < 4 | 36–58 | 78–93 | > 96 |
| MSRV | > 97 | < 4 | 36–58 | 78–93 | > 96 |
| MKTTn | > 97 | < 4 | 36–58 | 76–92 | > 96 |
The reported range defines a 95% confidence interval for the sensitivity and specificity respectively. Palm kernel meal was excluded from the calculation.
