Hardy Diagnostics has announced the new PDX-SIB test, which is both reliable and inexpensive with presumptive results available for the most common Salmonella spp. within 24 to 48 hours. The test is AOAC-RI approved and is specifically designed as a Critical Control Point surveillance tool. The Salmonella-selective enrichment medium contains a specific color change indicator that turns yellow when Salmonella spp. are present.
