Shelby Houlihan, the American record holder in the 1,500 and 5,000 meters, posted on social media that she’s been banned for four years following a positive test for what she concluded was a tainted pork burrito.

What You Need To Know

  • U.S. Olympic runner Shelby Houlihan wrote on social media that she’s been banned for four years following a positive test for the anabolic steroid nandrolone

  • Houlihan wrote that she believes that it's a false positive and attributed it to a tainted pork burrito

  • She said she’s since learned it has “long been understood by WADA (World Anti-Doping Agency) that eating pork can lead to a false positive for nandrolone, since certain types of pigs produce it naturally in high amounts. Pig organ meat (offal) has the highest levels of nandrolone”

  • Houlihan's coach Jerry Schumacher issued a statement maintaining her innocence, claiming she was "treated unfairly at every step of this process."

Houlihan’s announcement on her Instagram account Monday arrives days before the start of U.S. Olympic track and field trials in Eugene, Oregon, where the top three in each event earn a spot to the postponed Tokyo Games. She finished 11th at the 2016 Rio de Janeiro Olympics in the 5,000 meters.

The 28-year-old Houlihan said she received an email from the Athletics Integrity Unit (AIU) on Jan. 14, notifying her that a drug testing sample returned a finding for the anabolic steroid nandrolone. She said she’s since learned it has “long been understood by WADA (World Anti-Doping Agency) that eating pork can lead to a false positive for nandrolone, since certain types of pigs produce it naturally in high amounts. Pig organ meat (offal) has the highest levels of nandrolone.”

Houlihan made a list of all the food she ate leading up to a Dec. 15 test that produced the adverse analytical finding for the anabolic steroid.

“We concluded that the most likely explanation was a burrito purchased and consumed approximately 10 hours before that drug test from an authentic Mexican food truck that serves pig offal near my house in Beaverton, Oregon,” Houlihan wrote. “I notified the AIU that I believed this was the source.”

An email and text from The Associated Press were left with her agent.

Houlihan added that “although my levels were consistent with those of subjects in studies who were tested 10 hours after eating this source and WADA technical guidelines require the lab to consider it when analyzing nandrolone, the lab never accounted for this possibility. They could have reported this as an atypical finding and followed up with further testing. The anti-doping experts I have reached out to say they should have. I did everything I could to prove my innocence.”

She said she passed a polygraph and had a hair sample analyzed by toxicologists.

“WADA agreed that test proved that there was no build up of this substance in my body, which there would have been if I were taking it regularly,” Houlihan wrote. “Nothing moved the lab from their initial snap decision. Instead, they simply concluded that I was a cheater and that a steroid was ingested orally, but not regularly. I believe my explanation fits the facts much better — because it’s true. I also believe it was dismissed without proper due process.”

Houlihan said she was informed last Friday the Court of Arbitration for Sport, “did not accept my explanation of what had occurred and has subsequently banned me from the sport for four years.”

The ban, as it stands, would keep Houlihan out of the Tokyo games, as well as the 2024 Olympic Games in Paris and the World Athletics Championships in Budapest (2023) and Eugene, Oregon (2022).

“I feel completely devastated, lost, broken, angry, confused and betrayed by the very sport that I’ve loved and poured myself into just to see how good I was,” Houlihan wrote.

She set the American 1,500-meter record of 3 minutes, 54.99 seconds at the world championships in Doha, Qatar, on Oct. 5, 2019.

Last July, Houlihan broke the U.S. 5,000-meter mark with her time of 14:23.92 in Portland, Oregon.

“I want to be very clear. I have never taken any performance enhancing substances. And that includes that of which I am being accused,” Houlihan wrote. “I believe in the sport and pushing your body to the limit just to see where the limit is. I’m not interested in cheating. I don’t do this for the accolades, money, or for people to know my name. I do this because I love it. I have so much fun doing it and it’s always the best part of my day.

Houlihan's coach Jerry Schumacher issued a statement maintaining her innocence.

"Shelby’s positive test was for an exceedingly small amount of a substance that is known from WADA’s own studies to be present in certain types of pork — less than 12 hours after she ate at a Mexican food truck that served pig organ meat," he wrote. "I do not understand how any competent and unbiased body could fail to conclude that Shelby is innocent."

Schumacher went on to blast the anti-doping authorities in his letter to the Track and Field community, claiming Houlihan was "treated unfairly at every step of this process."

"Throughout this process we were confident that the truth would lead to justice," he wrote. "What I’ve come to learn instead is that anti-doping authorities are okay with convicting innocent athletes so long as nine out of ten convictions are legitimate. That is wrong."

"What we are witnessing here is a great tragedy in the history of American distance running," he continued. "Not only is Shelby an exceptionally talented athlete, but she has also developed her talent through hard work and discipline. She is tough as nails. She is an exceptional teammate. She loves to compete. She just might be the best 1500m runner in the world this year, but we will never get the opportunity to find out. And that’s a tragedy."
