[2022/03/10, 11:16:26] Gernot Redeke: Hi everyone. Is there any time span/guideline or recommendation on meat usage after darting with opioids? This is for hunting farms? [2022/03/10, 11:34:54] Erik Verryne: No. Not yet. But the SAVA Wildlife Group is supporting a current project by Silke Pfitzer et al looking into Thianil and naltrexone residue in buffalo muscle and organs [2022/03/10, 13:31:45] Gary Bauer: If there is no published withdrawal period, as far as my knowledge stretches, it defaults to 90 days [2022/03/10, 13:34:33] Richard Burroughs: Yes. That is the default legal period. There is no published withdrawal period. [2022/03/11, 17:55:32] David Gerber: According to the Vet Regulations, rule 10(6)cThe withdrawal period is 120 days or 10 times the half-life of a drug. In most cases, 10 x the half-life is much more friendly than the 120 days.I assume that there should be some literature about the half-life at least of etorphine and possibly thiafentanil.
