Abstract
Four rapid methods for detection of Salmonella , (i) the conventional fluorescent-antibody (FA) technique, (ii) a rapid direct FA technique, (iii) microcolony FA, and (iv) enrichment serology (ES), were compared with conventional cultural procedures. A total of 347 subsamples representing 16 different food prototypes, alleged to be naturally contaminated with Salmonella , were analyzed. From these samples, 52 were found to contain Salmonella by cultural methods. Conventional FA identified all 52 culturally positive samples, ES identified 51, microcolony FA identified 48, and the rapid FA method identified 34. The number of false-positive samples for each procedure was: ES-selenite, 7; tetrathionate, 8; rapid FA, 26; microcolony FA, 33; conventional FA-selenite, 27; tetrathionate, 26. Tetrathionate enrichment was found to be superior to selenite for Salmonella recovery from most foods, but the concurrent use of both media allowed maximum recovery.
