She faced a four-year ban, but the federation said an ethics hearing panel ruled "she was found to bear no fault or negligence for the violation, and thus no period of ineligibility has been imposed on her."
In her defense, she collected eight samples of beef and pork in July from a buffet restaurant she regularly eats at in Thailand, and testing discovered traces of clenbuterol, despite it being banned in Thailand since 2003. Because of that national ban, the panel agreed with her that she had no reason to know or suspect that she might eat contaminated meat.
Farmers add clenbuterol to cattle feed to reduce fat. The panel also noted the clenbuterol in her system was also well below minimum levels of concern, and an anti-doping test of her two weeks beforehand was clean.
Ratchanok became the youngest world champion in 2013 at 18, and she became the first Thai to reach No. 1 in the world in 2016.
