Brilliant Green Agar is used for the selective isolation of Salmonella spp. in a laboratory setting. Brilliant Green Agar is not intended for use in the diagnosis of disease or other conditions in humans.

Kristensen, Lester, and Jurgens first described the use of Brilliant Green Agar as a primary plating medium for the isolation of Salmonella. The report described the medium as useful for the differentiation of "paratyphoid B" from other intestinal Gram-negative bacilli. Kaufmann modified their formula and used Brilliant Green Agar in addition to Tetrathionate Broth for the isolation of Salmonella from stool specimens. The outstanding selectivity of this medium permits use of moderately heavy inocula, which should be evenly distributed over the surface. Brilliant Green Agar is used in the microbial limits test. Brilliant Green Agar supplemented with novobiocin is used in food testing.
