(The Sports Xchange) - The NFL Players Association is warning players about eating meat from China and Mexico that might be contaminated.
In a letter to players and shared on social media by at least two players -- Arizona's Patrick Peterson and Baltimore's Steve Smith -- the NFLPA reminds players they are ultimately responsible for what they put in their bodies.
"There is some evidence that some meat produced in China and Mexico may be contaminated with clenbuterol, an anabolic agent which is banned by the NFL Policy on Performance-Enhancing Substances," the letter reads.
