Conclusion
1
Within the statistical constraints of these studies, no differences were found between the reference
2
culture-based methods and the alternative BAX® System method. These results indicate that the
3
alternative method can be used to allow uncontaminated food to be released rapidly from a
4
manufacturer’s control and prevents
Salmonella
-contaminated foods from entering commerce.
5
Furthermore, this test method can be a valuable tool for outbreak investigations when food
6
contamination events occur.
7
Collaborator feedback indicated that the method was easy to use and that the clear yes/no results
8
provided by the BAX® System software were appreciated. Time and labor savings were cited as key
9
advantages of the test method over the reference culture methods. No negative feedback regarding the
10
method was provided by any of the collaborators.
11
It is recommended that the BAX® System Real Time
Salmonella
PCR test kit be adopted as Official First
