Compact Dry LM | Listeria monocytogenes
Box of 100 plates
Compact Dry LM plates give you a fast, reliable way to confirm Listeria monocytogenes in food and environmental samples. Each pre-sterilized dish is infused with selective agents and chromogens. Target colonies develop as red colonies, other Listeria appear blue/green, and background flora are suppressed, making interpretation clear.
Compact Dry LM streamlines Listeria testing—delivering easy-to-read results that keep HACCP programs on schedule and products safe.
Key Benefits
- MicroVal-validated – proven equivalent to ISO 11290-1/-2 across a broad range of foods, giving auditors and regulators confidence.

- Ambient-stable & stackable – store at 1 – 30 °C; slim profile maximizes incubator space.
-
Versatile QA coverage – ideal for in-process and finished-product checks in dairy, meat, produce, seafood, bakery, and ready-to-eat facilities.
