The State Agricultural Laboratory provides for the mandatory certification of laboratories providing agricultural laboratory services to agencies and departments of this state or its political subdivisions, including those laboratories that are a part of a state agency or department or a political subdivision of this state. You can see a list of currently certified labs here: SAL Certified Labs
Scientists from the State Agricultural Laboratory (SAL) are certified by the U.S. Food and Drug Administration (FDA) as Laboratory Evaluation Officers (LEOs). As such they provide FDA mandated audits and inspections of dairy testing laboratories which provide certain types of testing. When compliance is reached, the laboratories achieve Approved status for such testing. You can see a list of all labs which are currently approved by the SAL LEOs here: SAL Approved Labs
The State Agricultural Laboratory is certified by the Association of Official Seed Analysts (AOSA) for the provision of seed testing services. We currently provide seed testing when it is necessary for the export of seed products.
