Buparvaquone tissue residue study

The Buparvaquone tissue residue study investigated tissue residues in cattle using Buparvaquone to treat tick borne Bovine anaemia.

Summary

Bovine anaemia caused by Theileria orientalis is a tick borne disease that has been identified as the cause of significant morbidity and mortality of cattle in eastern Australia. Buparvaquone (BPQ) is expected to be a highly effective chemotherapeutic which is supported by efficacy studies (MLA project B.AHE.0048). Currently BPQ is not registered for use in Australia. This tissue depletion study provides data that could be used by industry to establish a withholding period for BPQ. Detectable residues were present in meat, back fat and perirenal fat up to 119 days post treatment.

Quantifiable residues were still present in liver, kidney and neck muscle (site of administration) 147 days post treatment.

Project concluded: 28 February 2013
