In the wake of the recent trimetazidine (TMZ) doping scandal involving 23 Chinese swimmers, the New York Times has reported that three of the swimmers had previously tested positive for clenbuterol, a banned substance, in 2016 and 2017. Chinese authorities have maintained that the athletes ingested the substance through contaminated meat, while the World Anti-Doping Agency (WADA) has acknowledged that the clenbuterol levels detected were below the minimum reporting level. However, the revelations have raised concerns about the handling of doping cases by WADA and the prevalence of clenbuterol contamination in meat.
