Improved Isolation of Salmonellae from Naturally Contaminated Meat Products by Using Rappaport-Vassiliadis Enrichment Broth

Abstract
A total of 454 specimens of meat products were examined for salmonellae by using 5 procedures of enrichment. The use of a selective motility medium, inoculated from enrichment in Muller-Kauffmann broth, resulted in an increase in the number of positive specimens. Simple enrichment in Rappaport-Vassiliadis broth, after pre-enrichment, was more sensitive and specific for recovering salmonellae than the selective motility medium Muller-Kauffmann broth method.
