SUBJECT: DSM Food Specialties' Delvo®Scan Reader For The Delvotest® P 5 PACK

The Food and Drug Administration's (FDA) Center for Veterinary Medicine (CVM) has evaluated data supporting the use of DSM Food Specialties' Delvo®Scan Reader as an instrument reader for the Delvotest® P 5 PACK.

The Delvo®Scan Reader has been validated as a reader when testing raw, commingled bovine milk and pasteurized bovine white milk (0%-3.5% fat) for amoxicillin, ampicillin, cephapirin and penicillin-G.

The data have been evaluated in accordance with the standards established for the acceptance of screening tests for raw, commingled bovine milk used for testing in accordance to the provisions of Appendix N of the Grade "A" Pasteurized Milk Ordinance (PMO).

The data submitted demonstrated that the Delvo®Scan Reader provides results equivalent to the results obtained from visual reading. No changes to the 90/95 concentrations or sensitivity data currently listed on the label and in M-a-85 are required. It is important to note that as no changes were made to the 90/95 concentrations, this is not considered a new test, and the visual reading option is still available. The printout from the reader used with the test must meet the current requirements for printing results.

CVM's evaluation of the data presented by DSM Food Specialties indicates that the performance of the Delvotest® P 5 PACK when used with the Delvo®Scan Reader meets the standards established for acceptance of screening tests for monitoring raw, commingled bovine milk and pasteurized bovine white milk in accordance with the provisions of Appendix N of the PMO.

NOTE: The Delvo®Scan Reader has not been evaluated for use to test bovine cream or chocolate milk. For these products, the Delvotest® P 5 Pack must be read visually.
