Legionella is a type of pathogenic bacteria that are linked with water systems, consisting of water tanks, pipework, showerheads, and whirlpool baths usually discovered in domestic properties. In the case whereby the bacteria becomes airborne, that is, in a water spray, brume or vapor, then they could be inhaled by people, thereby causing a range of pneumonia-likee ailments.
As of 2014, about 342 people were recorded to be diagnosed by legionella bacteria, although it is a fair number, the health effects can be chronic that's why it is required we do everything that's within our reach to control the risks.
According to the Health and safety executive on Legionnaires' diseases, which says the control of legionella bacteria in water systems, approved code of practice L8 - draws out the blueprints and licit necessities for people concerning how to manage and minimize the dangers brought about by legionella bacteria.
Because domestic properties are regarded as "low venture" in terms of legionella, it is not compulsory that a risk assessment to be performed by a Professional or Specialist unless you don't just feel assured or secured performing the evaluation yourself. It is only necessary we lookout for small legionella risks and has a record of our discoveries.
Laboratory procedures for Legionella testing
Legionella bacteria can develop when water in plumbing lines are not tested consistently. When a risk assessment sources for legionella, there are different types of sampling and detection methods that could be used in legionella testing Glasgow laboratory. Every test method has different potency when considering if the bacteria are in the water sample.
When legionella testing Edinburgh laboratory is in a water sample, there are two major ways that could be used, which are swab and bottle.
Swab sampling as to do with the collection of a surface sample with a sterile swab. This swab sampling is not often used, which is because the spread of legionella is by individual bacteria drifting in the aerosol or spray. In contrast, swab sampling doesn't allow measurement of the quantity of legionella in the water producing an aerosol or spray. Bottle sampling (Bottle bulk water sampling) is the most used method. Bottle sampling involves the collection of water from drinkable water fixtures. It allows the measurement of the quantity of legionella according to each specific volume of water.
Culture method- This a detection method legionella testing Edinburgh laboratory can perform. To detect legionella colonies on BCYE agar, the legionella culture method is used. This detection method takes ten days to achieve, thereby wasting time, which would be needed to prevent exposures and finding the root. The culture method for environmental water sampling is usually not true; this is because legionella colonies on BCYE agar are usually developed or held back by rivalrous microbial flora which guise the presence of legionella colonies, especially with water sampling which are taken from warm water - holding mechanical equipment exposed to our environment, such as; Cooling towers, fountains, and Saunas.
