The University of Maine is an equal opportunity/affirmative action institution.

The Cooperative Extension Diagnostic and Research Laboratory brings together scientists researching animals, agriculture, insects, and plants under one roof. The unique combination of researchers provides many teaching opportunities for students, as well as premier research and outreach facilities.

By allowing for research contributions to agriculture, public health, communities, and wildlife, the lab aims to benefit Maine in a variety of ways, including protecting the natural resource- and food-based economies, adding to food safety and human health, and providing unique diagnostic and testing services to farmers, homeowners, and the public.
