Olympic athlete banned for steroids, blames it on a burrito she ate

Just weeks before the Olympic track trials US runner Shelby Houlihan has been suspended after testing positive for the steroid nandrolone. Houlihan insists that she wasn't doping but the positive test was caused by the burrito she had eaten earlier. From CNN:

Houlihan said in a post on Instagram Monday that a burrito she ate before the test contained pig organ meat, or offal, which she said can lead to a positive test for nandrolone.
