Compact Dry LS is a simplified medium to identify Listeria spp. by the combination of selective agents and chromogenic substrates. Due to the chromogenic substances it contains, Listeria grow as blue colonies with a diameter of 1 – 2 mm. Listeria monocytogenes are considered to be the main cause of food poisoning. Compact Dry LS can be used to test any food, water and beverage to ensure food safety.
