PRODUCTS IDEXX LAUNCHES NEW RAPID
WATER TEST IDEXX has announced the introduction of Legiolert, a new culture testing method that enables building owners and facility managers to simplify water testing and reduce the risk posed by Legionnaires’ disease.
Legiolert is a highly-sensitive method for the confirmed
detection of Legionella pneumophila (L. pneumophila), in water for use across Europe, the Middle East and Africa and delivers results to decision makers up to seven days faster than traditional testing methods. Legionella pneumophila is the most common Legionella species in water and the primary cause of Legionnaires’ disease, which is deadly for about 1 in 10 people who contract it and often causes long-lasting symptoms for survivors.
Launched in 2016 in North America, Legiolert improves public health response times by accurately and sensitively quantifying L. pneumophila in water, providing a confirmed result in seven days, versus up to 14 days with traditional culture methods. The new test does not require laborious colony counting or confirmation steps that reduce the need for training and the risk of interpretation errors and frees up time for laboratory staff.
Leading water microbiology consultant David Sartory recently concluded that the IDEXX Legiolert™/Quanti-Tray® test is superior to the standard method for quantifying L. pneumophila. His assessment was part of a peer-reviewed study, “Evaluation of a most probable number method for the enumeration of Legionella pneumophila from potable
GREATER-THAN-EVER NEED FOR
FACE-FIT CHECKING New global research, which found that deaths from cancer in the workplace are higher than previously thought, underlines the growing necessity for respiratory protection to have face-fit checking built-in.
According to the research, conducted by various international research organisations including the European Occupational Safety & Health agency and presented at the XXI World Congress on Safety and Health at Work in Singapore on 4th September 2017, occupational exposure to carcinogens kills around 742,000 people globally every year, a sizeable increase from the previous estimate of 666,000 p.a.

and related water samples,” published in the April 2017 issue of Letters in Applied Microbiology.
“With Legiolert, we continue our commitment to innovation in diagnostic technologies to improve the safety and quality of water worldwide,” commented Andrew Headland, Senior Business Manager for IDEXX Water. He added, “Legiolert is so much more sensitive and accurate than current culture methods. Combined with the fact that the product is extremely easy to use and requires minimal training, we expect to see an increase in on-site testing for Legionella pneumophila as well as wide-scale adoption in laboratories.”
The Legiolert test is based on a bacterial enzyme detection technology that signals the presence of L. pneumophila through utilisation of a substrate present in the Legiolert reagent. L. pneumophila cells grow rapidly and reproduce using the rich supply of amino acids, vitamins and other nutrients present in the Legiolert reagent. Actively growing strains of Legionella pneumophila use the added substrate to produce a brown colour indicator.

inhaled carcinogens is twice that from fatal accidents, which number around 380,000 a year, emphasising the need for workers to be supplied with a fit test check system built-in, to secure a correct fit and ensure there is no inward leakage around the mask seal.
The JSP Force 8™ half mask fitted with PressToCheck™ P3 Filters allows the wearer to close off the airflow in order to check the face fit every single time it is put on throughout the day, protecting the wearer from any inhalable dust (including very fine silica dust), particles or aerosols. PressToCheck™ is revolutionising workplace respiratory protection, and is rapidly replacing the inferior, often poorly-fitting, FFP3 disposable mask worldwide.
According to a HSE study, only 41.9% of wearers who thought they had a positive fit using an FFP3 disposable mask actually achieved this when later tested. In contrast, JSP test results show that 97.1% of people using PressToCheck™ achieve a positive fit test result.
Winner of the 2014 BSIF Product Innovation of the Year Award, PressToCheck™ is the UK’s leading respiratory protection solution with integral face-fit checking. It has brought a vast improvement in workplace health and safety across the globe.
