Listeria Selective Enrichment Broth CM0862 is based on the formulation described by Lovett et al. and is recommended for the enrichment of Listeria species in food. Subsequent work has concluded that the enrichment properties can be improved by increasing the buffering capacity of the medium by the addition of potassium di-hydrogen orthophosphate and disodium hydrogen orthophosphate. Buffered Listeria Enrichment Broth is therefore a modification of the original medium.

• Intended for use with samples of fermented products and as an alternative method for enrichment of environmental specimens
• Also available Listeria Selective Supplement, Part No. SR0140E or SR0143E; Modified Listeria Selective Enrichment Supplement, Part No. SR0206E or SR0206B; and Listeria Selective Enrichment Supplement, Part No. SR0141E

Listeria Selective Enrichment Supplement contains cycloheximide and is toxic if swallowed, inhaled or by skin contact. As a precaution when handling wear gloves and eye/face protection. Acriflavine is activated by light and may form compounds inhibitory for Listeria.
