It is the purpose and intent of this section that the department desires to make its personnel, facilities and laboratories available to such persons and to determine if such feeds are in compliance with the provisions of ORS 633.006 to 633.089 or for any other purpose that the department may determine is reasonable and necessary.

(2) The department may provide for the obtaining, handling and testing of samples of bulk commercial feed and custom mixed feed as provided in subsection (1) of this section, including split sampling thereof with portions of each sample being made available to the seller and to the contract feeder or person feeding the feed to animals. Copies of the final results of the tests or analysis, which shall not be a public record, shall be made available only to the seller and to the contract feeder or person feeding the feed to animals.
