Why use Legipid?
Real time management of Legionella Risk
Until recently, Legionella testing was confined to regular sampling and testing with growth based methods (culture). With a 10-14 delay to results, managers were unable to control risk in real time due to the absence of accurate information. This inevitably results in higher operational cost (OPEX) and business interruption in order to ensure compliance. Costs arise due to the loss of confidence:
- Unnecessary investment in expensive preventative maintenance
- Hidden cost from business interruption while waiting for test results
Legipid provides an accurate result in just 1 hour. Risk can be pro-actively managed with total confidence so you only incur cost when necessary.
Business pressure to avoid disruption had led to interim plate counts to give a ‘presumptive count’. Despite best endeavours, these can be notoriously inaccurate and often require a decision based on less than adequate information. Facilities management are caught in a dilemma; ignore a possible positive result and be found negligent should an outbreak occur, or undertake costly but potentially unnecessary remedial action “just in case”. If you opt for the latter, you could be incurring many thousands of pounds of needless remediation and business interruption.
Legipid removes the need for presumptive plate counts. Act on accurate information and only incur cost when necessary.
Post remediation, re-testing to ensure a system is compliant creates further delays and interruption.
Ironically, if remedial action involved the application of a biocide, this can inhibit growth by culture. The presence of VBNC (viable but non-culturable cells) can also go undetected by culture methods. Alternative fast methods such as PCR is also known to produce a false positive result in the presence of dead cells, incorrectly indicating that remedial action has not been effective.
Legipid will accurately detect Legionella, even in the presence of growth inhibitors and give an accurate result post remediation.
As the “gold standard” culture testing is written firmly into the HSE guidance. With the emergence of various fast testing methods the guidance is continually under review and online editions are subject to frequent updates. Register with us for updates or contact the HSE directly.
The purpose of regulation is to prevent and contain risk to public health in the event of an outbreak; this requires prompt action to be most effective. With a delay of 10-14 days, a dependence on culture testing inevitably places people at risk. It is not a question of if provisions for fast testing will be included in the guidance, but when.
