Adverse Analytical Findings: An anti-doping review has found World Aquatics to be "transparent and collaborative" in its review of the contamination case involving 23 Chinese swimmers. The 23 Chinese swimmers tested positive for trimetazidine (TMZ) in January 2021 after having allegedly been inadvertently exposed to the substance through contamination.

After an investigation, the Chinese Anti-Doping Agency (CHINADA) decided that the Adverse Analytical Findings (AAFs) for TMZ were an isolated mass incident caused by athletes' consumption of food contaminated with TMZ when they were participating in the event, reports Xinhua.

It was then decided that the athletes involved would be "held to have no fault or negligence, and the AAF cases should not be brought forward as Anti-Doping Rule Violations (ADRVs)."
