Regional Market Outlook
North America tops the microbiologically-tested water products market by introducing molecular testing and promoting building water safety. However, European countries rely on their regulatory standards and regularization testing to maintain their competitive edge. Asia-Pacific is expected to be a new water market player due to rising industrial water demand and urbanization processes. In South America and the Middle East & Africa, the municipalities expansion, development of desalination, and water reuse are among the factors for a growing market.
MicroVal Certification Strengthens Testing Portfolio
Bio-Rad has received MicroVal certification of its new methods for Listeria detection in 2026. These molecular methods were first validated by AOAC and now have double validation (AOAC + MicroVal, as of June 2026). BioRad offers PCR-based multiplex methods for rapid and accurate detection of pathogens, while also including internal controls integrated, in case of the testing done on food or the environment.
Direct-to-Consumer Testing
The increasing public interest in microbiologically safe drinking water presents a good opportunity for laboratory services to offer testing to the public beyond their regular clients (i.e. businesses that need it in the supply chain, or those required to do it under regulation). Simple home testing kits, residential sampling services and clear digital reports can help companies build direct relationships with increasingly informed urban and semi-urban consumers.
