Listeria monocytogenes Count Plate

1. Product Overview

FSTest Listeria monocytogenes Count Plate is a ready-to-use, single-use dehydrated culture medium system engineered for the rapid, precise, and cost-effective detection and enumeration of Listeria monocytogenes in food, beverage, and environmental samples.

Utilizing an advanced specific chromogenic enzymatic reaction, Listeria monocytogenes colonies hydrolyze the substrate during incubation to form distinct, characteristic colonies. This eliminates the labor-intensive process of traditional agar media preparation (boiling, autoclaving, pouring plates) while providing clear, error-free visual interpretation. It is highly suitable for food manufacturers and food hygiene inspection institutes to perform rapid and efficient testing on food, water samples, and environmental surfaces.

2. Key Benefits

• Fast Time-to-Result: Delivers definitive colony counts in just 36–48 hours, saving up to 4–7 days compared to traditional culture and MPN methods.

• Ready-to-Use & Zero Media Prep: No glass Petri dishes, autoclaving, or agar preparation required—simply inoculate, incubate, and read.

• High Sensitivity & Accuracy: Detection limit as low as 1–10 CFU/mL (g), ensuring compliance with strict international food hygiene standards.

• Unambiguous Visual Reading: Highly specific chromogenic reaction produces vivid blue-green colonies, drastically reducing manual counting errors and false results.

• Space & Cost Efficiency: Ultra-thin paper-film format takes up minimal storage and incubator space, while significantly reducing biohazard disposal waste and shipping costs.

• Flexible Transport & Long Shelf Life: Stable at ambient temperatures (up to 15 days of room temperature shipping without cold chain reliance) with a 18-month shelf life under standard refrigeration.

6. Performance & Validation

• Colonies/dots growing as blue-green on the count plate are considered positive for Listeria monocytogenes; if there is no growth or if dots of other colors appear, the result is considered negative.
