To best understand the ‘summer risk’ in relation to the incidence of Legionnaires’ disease, it’s useful to refer to the Legionella surveillance reports issued by Public Health England (PHE), which succinctly summarise the monthly position (total reported and total confirmed cases of Legionnaires’ disease) whilst offering year-on-year comparison data.

TVC testing explained and how applicable it is to take a TVC sample?

Posted by Paul Limbrick on Mar 27, 2019 2:21:31 PM

In this blog we explain what a TVC sample is, what the results mean and when a TVC sample can help inform on water safety…

TVC stands for ‘total viable count’, a laboratory test that indicates the level of heterotrophic organisms within a sample. Heterotrophs are a large group of organisms that can be further divided into fungi, yeasts, moulds and bacteria. Therefore, the results of a TVC test may offer an indication into the ‘general level’ of contamination within a system.

Controlling the Chain of Infection

Posted by Paul Limbrick on Mar 6, 2019 7:20:00 AM

If we’re to control the ‘chain of infection’ we must first understand what it entails so that we can identify what is within our control.  In doing so, this may enable us to devise and implement an effective ‘preventative management strategy’ in order to mitigate the risk of infection and subsequent disease.

How to control Legionella – Part 2: the risks and the options…

Posted by Paul Limbrick on Aug 8, 2018 10:47:52 AM

As discussed in Part 1, temperature has limited effectiveness when treating biofilm bacteria (especially mature biofilm) but colonisation of a system with biofilm bacteria may (in the main) be avoided should water temperature be kept within specification and the water within the system kept in regular movement/turned over. Moreover, when outlets test positive for bacteria of ‘human importance’, it’s first of all important to question ‘why’ and to ascertain to what extent the water system has been compromised (ie, how big is the loss of control…?).
