Comprehensive Guide to AOAC 991.39 Detection of Cryptosporidium Oocysts in Water Testing Services by Eurolab

The detection of Cryptosporidium oocysts in water is a critical aspect of ensuring public health and safety. The American Association of Official Analytical Chemists (AOAC) has established Standard 991.39, which outlines the methods for detecting Cryptosporidium oocysts in drinking water. This standard is widely recognized and adopted globally, and it serves as a benchmark for laboratories to follow when conducting this type of testing.

Legal and Regulatory Framework

The detection of Cryptosporidium oocysts in water is governed by various laws and regulations at both the international and national levels. The Safe Drinking Water Act (SDWA) in the United States, for example, requires public water systems to monitor for Cryptosporidium oocysts on a regular basis. Similarly, the European Unions Drinking Water Directive sets limits for Cryptosporidium oocysts in drinking water.

International and National Standards

Several international and national standards apply to the detection of Cryptosporidium oocysts in water, including:

  • ISO 15549:2004 (International Organization for Standardization)

  • ASTM E2431-06 (American Society for Testing and Materials)

  • EN 16140:2015 (European Committee for Standardization)

  • TSE 537:2007 (Turkish Standards Institution)

    • Standard Development Organizations

    Standard development organizations, such as AOAC, ISO, and ASTM, play a crucial role in establishing and maintaining standards for laboratory testing. These organizations bring together experts from various fields to develop and update standards that reflect the latest scientific knowledge and technological advancements.

    Evolution of Standards

    Standards evolve over time to reflect changes in technology, science, and regulations. New methods and techniques are developed, and existing standards are updated to incorporate these advancements. For example, AOAC 991.39 was revised in 2019 to include new methods for detecting Cryptosporidium oocysts.
