Reference Samples for the Evaluation of Salmonella Isolation Methods
Reference samples consist of gelatin capsules containing 0.2 g of spray-dried milk inoculated with Salmonella. These reference samples enable each laboratory to test individually the performance of Salmonella isolation methods and to study the effects of foods and its competitive flora on the isolation of Salmonella. The reference samples have also been found useful in collaborative studies testing the reproducibility of methods. It is recommended to evaluate the performance of Salmonella isolation methods with reference samples.
