(CNN)Note to NFL players: Before you eat that steak on your Cancun vacation, find out where it came from.
The NFL and NFL Players Association have warned players in a memo about consuming meat from Mexico and China that might contain clenbuterol, a performance-enhancing drug.
"There is 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 NFL and NFLPA said in a joint statement to players. "Consuming large quantities of meat while visiting those particular countries may result in a positive test for clenbuterol in violation of the Policy."
NFL spokesperson Brian McCarthy told CNN that the league wanted to warn the players and urged the drug program's independent administrator to send that memo.
"Thanks for the heads up," Baltimore Ravens wide receiver Steve Smith Jr. said on Twitter in reference to the memo. "If you have a few steak dinners on vacation your (sic) screwed."
