EMD Millipore’s Readybag pouches with granulated culture media are now available in larger pack sizes to enable pathogen testing of composite food samples. Composite samples are larger than traditional food samples and therefore require the addition of more culture media before incubation. The Readybag pouches are now available in 86 gram packs for testing of Salmonella in 375 gr/ml samples and 63 gram packs for testing of Listeria in 125 gr/ml samples. Both Readybag pouches are also available in packs for standard 25 gr/ml samples.

The pre-weighed, gamma-irradiated pouches eliminate all media preparation steps and reduce typical sample preparation time by more than 50 percent. Readybag granulated media pouches do not require capital equipment costs and involve less labor than both high efficiency and traditional methods for sterile media creation. Performance tests confirm that Readybag media provides similar results compared to non-irradiated, autoclaved culture media.
