Anti-doping tests conducted during the 2026 World Cup have returned what are known as “atypical findings” for eight players from the Tunisia national team. The detected substance was clenbuterol, a banned performance-enhancing drug.
Clenbuterol is a substance that can be used to enhance physical performance, particularly for fat loss and boosting endurance. Due to these effects, it is strictly prohibited under global anti-doping regulations.
At this stage, there is no indication of intentional doping by the Tunisian players, as the test results have been classified as “atypical findings” rather than positive doping violations. In anti-doping terminology, this means the levels detected are low enough to trigger a routine review rather than an automatic suspension or immediate sanction.
Investigators currently believe the most likely explanation is that the players consumed contaminated meat during their stay in Mexico, where similar cases have been documented in the past.
It is worth noting that Tunisia finished at the bottom of their group in the 2026 World Cup following three consecutive defeats against Sweden, Japan, and the Netherlands, respectively.
