Rapid Detection of Salmonella from Meats by Oxoid Salmonella Rapid Test

Abstract

The Oxoid Salmonella Rapid Test (OSRT) that utilizes a selective enrichment motility technique to detect Salmonella in foods was evaluated with pure cultures and naturally contaminated raw meat. All motile Salmonella strains tested by the OSRT gave positive results Non-motile Salmonella strain gave negative results. None of hydrogen sulfate-positive bacteria such as Citrobacter freundii, Edwardsiella tarda and Proteus spp gave a positive results. OSRT was compared with the standard culture method for detection of Salmonella in 77 samples of naturally contaminated chicken meat. Twenty-nine (37.6%) of these samples were positive by OSRT and 30 (39.0%) by the culture method. OSRT was found to be a rapid screening method for detection of Salmonella in food.
