The Food, Water and Environmental sections of Public Health Wales carry out a wide range of methods for the examination of all types of foods and waters.
These tests include standard microbial quality indicators such as aerobic colony counts, fungal counts, coliforms, faecal streptococci (enterococci), Listeria species, Enterobacteriaceae and Escherichia coli and specific pathogens associated with food and water such as Campylobacter, Salmonella, Listeria monocytogenes, E.coli O157, coagulase positive Staphylococcus, Clostridium perfringens, Bacillus cereus, Legionella, Cryptosporidium and Pseudomonas aeruginosa.
Within Public Health Wales there are four centres providing microbiological services linked to testing food, water or environmental samples. Three centres (Bangor, Cardiff and Carmarthen as seen below) collectively provide a wide test repertoire working to common methods and can give advice on sample collection, appropriate tests to undertake in a given situation and any relevant statutory tests.
Test repertoires at each site reflect the mix of samples that Local Authorities and private customers request in their area. Legionella culture from water samples is only available at the Cardiff site.
These three sites are all official food control laboratories for Wales and they are all UKAS accredited (test schedules are available on the UKAS website). Two of the centres are based in their respective Public Health Wales Microbiology laboratories but the third site (Cardiff) is based at the Llandough hospital site.
The fourth centre is the Cryptosporidium Reference Unit (CRU), based at Public Health Wales Microbiology, Swansea. This does not provide the range of services found at the other four sites but provides advice related to sampling for Cryptosporidium; confirmation of identification and management and control of the parasite.
Testing for Cryptosporidium in water samples in undertaken on behalf of the CRU by CREH Analytical Limited in Leeds, an arrangement supported by a memorandum of understanding. The CRU in Swansea is the England and Wales reference centre for genotyping Cryptosporidium isolates.
Below is a listing of all the five sites and the key individuals who can be contacted by telephone about the service that Public Health Wales can provide. To send a query to a particular site via this website, please use the on-line enquiry forms provided for each laboratory. Please either contact your nearest local laboratory or the CRU specifically in relation to Cryptosporidium if you need further information.
