Evaluation of Stabilized Bismuth Sulfite Agar for Detection of Salmonella in Foods.

The combination of a new manufacturing process, packaging, and media engineering has all contributed to the development of extended shelf-life (stabilized)-plated media (DuraPak). One of the first products stabilized by this process was bismuth sulfite agar plates (BSA). Stabilized BSA were stored 3-4 months at 35°C and then were inoculated in parallel with lab-prepared BSA following overnight aging at room temperature.
