A modified colorimetric enzyme-linked immunosorbant assay (ELISA) for Salmonella detection was compared to the standard culture method of the Bacteriological Analytical Manual/Association of Official Analytical Chemists (BAM/AOAC) using 20 artificially contaminated foods (1,200 test samples). The modifications to the current methodology consisted of an elevated incubation temperature of 42°C for the tetrathionate selective broth and M-broth postenrichments, as well as addition of 10 μg/ml novobiocin to the M-broth. The microtiter plate as not agitated during assay incubation, and centrifugation steps were eliminated from the protocol. This modified ELISA method was at least as productive as the standard AOAC culture method for the food samples tested. No false-positive reactions were encountered. The false-negative incidence was 1.5% for the immunoassay and 5.3% by the AOAC cultural method. The incidence of agreement between the methods was 96.7%.
