As another poster pointed out, they did hire a private investigater, and bought more burritos and tested them, and also asked for information about the source of their meat and offal. Most athletes would not be able to afford the 6-figure expense.
There is nothing illegal or wrong with selling boar meat in the USA that contains endogenous nandrolone, so there would be nothing to tell the health department, there was no "contaminated" meat, and no basis for any lawsuit.
Any "blame" for the "governing body", and the direction for reform of the WADA Code, is what USADA CEO's Travis Tygart complains against regarding 2015 changes in the WADA Code that places the burden on athletes to investigate the source, which unfairly burdens innocent athletes as collateral damage, in order to make it easier to punish the guilty ones based on presumption alone.
The TD2021NA should also make more clear when its explicit comments regarding pork offal ingestion must be applied, to avoid the ambiguity that reporting the positive as an AAF was both required by the standard (opinion of the majority of the CAS panel), yet deviated from the applicable testing standards (opinion of the minority of the CAS panel). The CAS explained that the WADA Lab has the prerogative to interpret what to report, while later stating that it is not up to the WADA Lab to finally decide the (exogenous/endogenous) origin. It doesn't seem correct that the WADA Lab should have that prerogative arising from an ambuigity in the standard. WADA's intent should be clarified to remove the ambiguity. For an athlete, the difference in reporting is the difference between a 4-year ban, and being flagged for further testing.
