There's been at least two known cases within the last six years of contaminated meat being blamed for positive tests. Alvarez now sits in a no-win situation, where any winning decision for him will be heavily scrutinized.

Mexican superstar and middleweight contender Canelo Alvarez has tested positive for the banned substance clenbuterol, ahead of his anticipated rematch with unified middleweight world champion Gennady Golovkin, per Dan Rafael of

Contaminated meat is being called the cause of the positive test.

Golovkin and Alvarez are scheduled to meet on May 5 (HBO PPV) in Las Vegas at the T-Mobile Arena, for a rematch of their controversial draw from September. It appears the fight will proceed as scheduled.

Both boxers had agreed to be randomly tested by the Voluntary Anti-Doping Association for this fight and their previous clash.

Alvarez says he's embarrassed by the positive test.

I am an athlete who respects the sport and this surprises me and bothers me because it had never happened to me. I will submit to all the tests that require me to clarify this embarrassing situation and I trust that at the end the truth will prevail

Alvarez produced urine samples on Feb. 17 and Feb. 20, and both tests came back positive for trace amounts of clenbuterol, per a letter from VADA president Dr. Margaret Goodman.

There's a recent history of contaminated Mexican beef causing controversy.

In 2012, Erik Morales blamed contaminated meat for his positive tests before a rematch with then-junior welterweight world champion Danny Garcia in New York. However, Garcia dominated Morales, ending the Mexican's career with a fourth-round knockout.

In 2016, then-junior lightweight world titleholder Francisco Vargas was also popped, in front of a match with Orlando Salido. He too was allowed to slide, and the fight went to a brutal draw.
