ENVIRONMENTAL LABORATORY CERTIFICATION

The Illinois Department of Public Health has been designated by the U.S. Department of Health and Human Services and the U.S. Environmental Protection Agency as the certifying agency for approval of microbiological laboratories processing official samples of milk and water. The laboratory certification program ensures that approved laboratories use methods and techniques that are in substantial agreement with the current editions of Standard Methods for the Examination of Dairy Products, Standard Methods for the Examination of Water and Wastewater, and Official Methods of Analysis of the A.O.A.C. (Association of Official Analytical Chemists).

       evaluator to receive a packet containing a copy of the regulations and requirements, a request
