The Microbiology Laboratory, located in Olympia, supports the department's Food Safety Program by testing food and dairy products for food poisoning organisms and by examining food products for contamination by insects, rodents or filth.  The laboratory only accepts food samples from the Food Safety Program. 

Please contact the Food Safety Program (360) 902-1876, if you have questions about food testing. 

The laboratory also tests dairy products for quality and to meet requirements for the interstate shipment of milk. Laboratory staff inspect and certify commercial and dairy-industry laboratories performing officially sanctioned dairy microbiology.  

The Microbiology Laboratory used to support the department’s Animal Health Program by testing animal blood and tissue for disease to aid in disease eradication programs and to allow animals to move interstate or internationally.

As of July 1, 2009, the Microbiology Laboratory is no longer conducting any animal health testing.
