Table 6 Sensitivity and specificity of the NMKL71 (RVS), MSRV and EN ISO 6579:2002 (RVS + MKTTn) methods at different spiking levels of Salmonella.

From: A comparative study of cultural methods for the detection of Salmonellain feed and feed ingredients

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
  1. The reported range defines a 95% confidence interval for the sensitivity and specificity respectively. Palm kernel meal was excluded from the calculation.
