In today’s food-sensitive world, ensuring the safety of your products isn’t just best practice—it’s essential. One of the persistent microbial hazards in the food-production environment is Listeria monocytogenes (commonly just “Listeria”), a bacterium capable of surviving and even thriving in cold, wet, and processing-plant conditions.
Why Listeria is a Concern
-
Listeria is hardy. It can grow at refrigerated temperatures, making it a major concern for ready-to-eat (RTE) foods, cold-smoked meats, dairy products, and other chilled items.
-
Even though Listeria infections (listeriosis) are relatively rare compared to some other food-borne illnesses, when they do occur they can be very serious—especially for vulnerable populations (pregnant women, newborns, elderly, immunocompromised).
-
Regulatory frameworks demand rigorous monitoring. For example, in the EU, Commission Regulation (EC) No 2073/2005 lays down microbiological criteria for foodstuffs including Listeria in RTE foods.
How Listeria Enters and Persists
The bacterium can be introduced and persist in various ways in a food production environment:
-
Via raw materials (dairy, fish, meat),
-
Through equipment or surfaces where cleaning is incomplete,
-
via water or condensation in wet processing areas,
-
Or through cross‐contamination within cold storage or RTE production zones.
Once established, Listeria can form biofilms and remain resistant to standard cleaning if not properly managed.
Key Control Measures
To control Listeria in your facility:
-
Implement strict hygiene and sanitation protocols, especially for equipment, drains, floors, and cold-rooms.
-
Monitor regularly surfaces and finished products for Listeria and related indicators.
-
Ensure your cleaning regimes reach cold and damp zones that may otherwise be overlooked.
-
Adopt rapid and reliable microbial detection tools to identify contamination quickly and act before product release.
Introducing the Solution: Microlab Listeria
One of the newer and smarter tools available for on-site detection of Listeria is the Microlab Listeria system. Through collaboration with ZEULAB S.L., this compact device allows food processors to conduct in-house testing without needing a full laboratory setup.
How It Works
-
The device integrates enrichment, detection, and inactivation all within a single disposable unit. That means fewer handling steps, less risk of contamination, and simpler workflow.
-
Samples (food or surface swabs) are placed into the unit; the system incubates (typically 48 hours at ~37 °C) then delivers a visual result via an immunochromatographic lateral‐flow assay targeting the antigen p60 of L. monocytogenes.
-
The test claims a limit of detection defined as “absence in 25 g of sample or 100 cm² of surface” for the target organism.
-
Because it is sealed and self‐contained, the risk of cross‐contamination or exposure to the operator and the wider production environment is minimised.
Why It’s a Practical Choice
For facilities that may not have full microbiology labs or want quicker internal screening, Microlab Listeria offers major advantages:
-
Simplified workflow: no complex media preparations, fewer transfers, minimal training required for non‐specialist staff.
-
Safety: The closed device design helps keep sampling and testing safe even within a production environment.
-
Speed to result: While not instantaneous, the system reduces the time from sample to check compared to traditional lab outsourcing (and often gives more control).
-
On-site capability: Enables proactive on‐floor monitoring rather than waiting for external lab results, allowing faster response to potential Listeria presence.
Application Areas
This kind of in-house testing is suitable for:
-
Ready-to-eat food producers (salads, sandwiches, chilled meals)
-
Dairy and cheese production
-
Cold‐smoked fish or meats
-
Surface hygiene verification in processing plants
-
Environmental monitoring programmes in the meat, poultry, dairy, and bakery sectors
