Listeria Insite Swab Test

InSite Listeria Swab Device

Listeria Environmental Testing

Listeria monocytogenes, is an important foodbourne pathogen capable of causing serious illness.

There are well established traditional methods but these can take up to five days to obtain a result.

Listeria species are common colonisers in food factories where they may form biofilms that are difficult to remove, and act as reservoirs of persistent L.monocytogenes contamination for process foods if not controlled. The presence of Listeria species in the food factory is often used as an indicator for L. monocytogenes contamination.

The InSite Listeria Swab is a quick and easy test for the detection of Listeria species in food processing environments. The test contains a liquid media formulated with growth enhancers, antibiotics and chromogenic compounds specific to the growth of listeria species.

A colour change from yellow to light brown /black is a presumptive positive. Positive results are attainable in as little as 24hrs.

Advances in this product for 2016 a new swab wetting agent which has been modified to include non-hazardous buffering agent and salts in addition to existing neutralizing agents.

The improved device has been validated over 3 production batched (>5000) compared against the original device

This improvement will see significant improvement in the tests performance, increasing selectivity and specificity of this screening test thus reducing the number of false positives and increasing confidence in the results and its cost benefit.

All presumptive positive results should be confirmed by biochemical and molecular methods.
