SwabSURE Listeria is a direct screening test designed for the presumptive detection of Listeria spp., including Listeria monocytogenes, from food contact surfaces and manufacturing environments where regular sanitisation is performed.

The test provides clear visual results via a built-in color change system, simplifying interpretation.

Each kit includes a 45mm breakpoint swab with a foam tip pre-moistened in TSC Neutralising Buffer for efficient sample transfer. The system is ISO 18593:2018 compliant when used with a sampling template (e.g., TS/15-T40).

Targeted Detection

Listeria monocytogenes

Listeria ivanovii

Other Listeria spp.

Differentiates from non-pathogenic Listeria such as L. innocua

Inhibition of Background Flora:
Suppresses common background organisms including:

Bacillus spp.

Enterococcus spp.

Micrococcus spp.

Gram-negative species like Klebsiella spp. and E. coli

Recommended Use

Routine environmental and food contact surface monitoring

GMP-compliant surface testing

HACCP-aligned pathogen control programs

Suitable for use alongside ISO 11290-1 methodology

Limitations & Considerations

Screening only – all presumptive positives must be confirmed using standard or molecular bacteriological techniques.

Not for direct food contact – discard after use.

Not validated for uncleaned surfaces – may cause false positives or unclear results.

A negative result does not guarantee absence – possible causes include:

Low organism load

Ineffective neutralisation of sanitiser

Damaged cells unable to recover

Incubation at 25°C is recommended – reduces false positives, especially in high-contamination zones like drains or complex equipment. For more specific detection, see alternative chromogenic product SS-L01.
