The best practice is to avoid using the DELETE statement on a queue table because the operation requires a full table scan to rebuild the internal queue table cache. You should reserve this statement for exception handling.

A DELETE statement cannot be specified in a multistatement request that contains a SELECT and CONSUME request for the same queue table.
