Following the completion of the PTM study, an additional 17 matrices (15 foods/beverages and
7
2 environmental surfaces) were evaluated in a pre-collaborative study. Orange juice, frozen
8
peas, peanut butter, shell eggs, shrimp, white pepper, and infant formula were compared to the
9
FDA BAM method; ice cream, nonfat dry milk, and cocoa were compared to both the FDA BAM
10
and HC CAM methods; hot dogs, beef trim, ground beef with soy, and ground turkey were
11
compared to the USDA-FSIS MLG method and HC CAM methods. Environmental surfaces
12
(ceramic tile and plastic) were compared to both the FDA BAM and the USDA-FSIS MLG
13
methods. Method comparison data is presented in Appendix 10.1. Results obtained using the

BAX® System Real Time
Salmonella
test kit indicate no statistical difference when compared to
15
the corresponding reference method results. A full pre-collaborative study manuscript is
16
currently being drafted.
