Literature review on microbiological analysis of water
With the help of leading Quality Assurance QA and Quality Control QC microbiology specialists in Europe, a complete set of guidelines on how to start and implement a quality system in a microbiological laboratory has been prepared, supported by the European Commission through the Measurement and Testing Programme. The working group included food and water microbiologists from various testing laboratories, universities and industry, as well as statisticians and QA and QC specialists in chemistry. This book contains the outcome of their work. It has been written with the express objective of using simple but accurate wording so as to be accessible to all microbiology laboratory staff. To facilitate reading, the more specialized items, in particular some statistical treatments, have been added as an annex to the book.

Microbiological testing of water
Microorganisms can be studied using a range of technologies, most commonly microbial cultures, immunoassays — such as enzyme-linked immunosorbent assays ELISAs — and polymerase chain reactions PCRs. Microbial cultures are a way of multiplying microorganisms by growing them in specific culture media, which may be liquid or solid, under controlled laboratory conditions. They are used to determine the type of organism, its abundance in the sample being tested, and its susceptibility to antimicrobial agents. Immunoassays use antibodies to detect and identify specific proteins unique to the target microorganism. They may be quantitative, but more often are qualitative assays that simply determine the presence or absence of the analyte of interest. Single and multiplex PCRs are a more recent development.

Microbiological safety hazards cause most of the foodborne illnesses and include pathogenic bacteria, viruses, and parasites. Historically, pathogenic bacteria have been the most prevalent food safety hazard, with viral cases following closely behind according to the most recent CDC report on the etiology of foodborne illness CDC,
