Spannender Fall. In den WADA Dokumenten ist genau beschrieben, wie das laufen sollte:

"The presence in urine of clenbuterol or zilpaterol or ractopamine, or of zeranol or its Metabolite, at an estimated concentration at or below (≤) of 5 ng/mL shall be reported as an ATF, triggering a mandatory investigation by the RMA to determine whether evidence exists that establishes that meat contamination is more likely than not the explanation for the ATF. If there is sufficient evidence to accept meat contamination as the explanation, an ADRV shall not be asserted. If there is insufficient evidence to support meat contamination as the explanation, an ADRV shall be asserted. In such circumstances, the Athlete may still seek to prove meat contamination, as the basis for a plea in mitigation of the Consequences to be imposed for the ADRV."
Entweder lief da wirklich etwas schräg oder die o.g. Ermittlungen sind das, was zu der späten Bekanntgabe durch Swiss Sports Integrity geführt hat. In einem Interview erwähnte deren Chef ja, dass einige zusätzlich Analysen gemacht wurde.
