Damp materials or high humidity environments contribute to preferential conditions for mould growth. Moulds are capable of colonising and persisting on a vast array of surfaces due to their role in nature in the decomposition and nutrient recycling process in the environment. After flooding or water damage has occurred, insufficient remediation of the affected buildings can lead to favourable conditions for mould/fungal growth, both visible and hidden. Floor coverings such as vinyl, laminate and carpets as well as underlying insulation should be replaced where necessary. Where not replaced or left untreated, flooring can act as a favourable substrate for microbial growth. Additionally, any underflooring materials such as chipboard or joists should be replaced without hesitation if damaged, while any modifications such as cracks, heaves or discolouration may be indicative of damage that needs to remediated.

airmid healthgroup was delighted to attend the Irish Fungal Meeting which was held in NUI Maynooth on the 20th and 21st of June 2013. At the conference, an impressive collection of national and international delegates from academia and industry presented research in the fast developing area of fungal biology.
Gabriel Scientific, in conjunction with airmid healthgroup, launched The Pillow Check Up 2013 on RTE Radio 1’s The Mooney Show on the 17th of April. Listeners were invited to send their pillows for analysis at airmid healthgroup’s laboratories to measure the levels of mould, allergens and bacteria present in pillows around Ireland. The results revealed that one third of pillows sampled had evidence of dust mite allergen. All of the pillows were found to harbour bacteria, just under a third of which at high levels, while half contained detectable levels of mould. A variety of mould and bacterial species were identified including Candida, Aspergillus, Rhodoltorula, and Streptococcus.
There is a bewildering array of ISO and ASTM antimicrobial surface validation studies and a whole host of biocidal activity testing available. It can be very complex for companies to navigate their way through this and the results they get may not always translate into market valuable data. Control of indoor pathogens on surfaces and in the air is a highly topical issue, so we asked John Fallon PhD, Head of Microbiology at airmid healthgroup, to talk us through some of the testing we do at the laboratory and the relevance of this testing.
