Analysis of Pseudomonas Aeruginosa to Comply with New Department of Health Guidelines


Following the latest guidelines from the Department of Health, an increased focus is to be placed on the analysis and monitoring for the presence of Pseudomonas aeruginosa at hospitals that provide augmented care.

The focus on Pseudomonas aeruginosa has been highlighted due to the high risks associated with water systems whereby the water can come into direct contact with the patients, or is used by staff to clean equipment that will then come into direct contact with patients.

Severn Trent Services are able to test and confirm for the presence of Pseudomonas aeruginosa as outlined in the best practice guide issued by the Department for Health on 31st March 2012 entitled, “Water Sources and Potential for Pseudomonas aeruginosa Infection from taps and water systems”.

The method used by Severn Trent Services to analyse for Pseudomonas aeruginosa follows the guidance in “Annex 2 – Microbiological examination of water samples for P. aeruginosa”. This method uses a secondary conformation test to reduce the risk of false positive results occurring in the laboratory.

Our Analytical Services divison offer a broad spectrum of Microbiological testing which can include other forms of Pseudomonas. As well as the aeruginosa we also offer analysis for Total Viable Counts, E-coli, Coliforms, Legionella, Enterococcus, Clostridium, Salmonella, Listeria, Campylobacter, Staphlycoccus and Cryptosporidium.

Under the current Health Technical Memorandum 04-01 (HTM04-01), “The control of Legionella, hygiene, “safe” hot water, cold water and drinking water systems” there is no proviso for Pseudomonas aeruginosa, which this document covers and a new version of HTM04-01 to include Pseudomonas aeruginosa is expected in early April 2013.
