runninboy said:I always see beef mentioned, it is well know that horse is consumed in mexico, clenbuterol is very common in races horses, which would make far more sense IMO.
Here is some pure speculation from my part, supposedly clenbuterol is used as a diet aid for some people. Just rumours i have heard. High levels in a person seem much more likely to me from ingesting as a diet aid for someone who is not a top tier professional athlete, especially in a place that now is considered by people to have a food contamination risk.
There are no studies whatsoever that i could find on clenbuterol in combination with other drugs. We know drug combinations to be a powerful tool in the legal application of drugs, and combinations can drastically alter the rate at which drugs are metabolized. Even something as simple as grapefruit juice taken in combination with certain drugs can change the way they are absorbed by the body to the point of making them pontentially lethal.
Since we do not know the metabolic properties of clenbuterol in combination with other substances(especially tb500 or diruetics) it is impossible to assertain what amount found in ones urine constitutes a PED.
lastly from a beef producers point of view, looking at the "evidence" of beef contamination it is quite slim. When the AC story first broke i could easily find some studies on clenbuterol & cattle, later they became buried under hundreds of other results. Here is what i first found
In the 80's there was a study in Europe initially raising the possibility that cattle might benefit in muscle growth from the drug but further study was warranted. Subsequent studies showed detrimental effects of the drug on beef. Change of texture & taste of the meat, and most importantly most breeds actually losing more fat than muscle gained resulting in an overall loss of weight .
Most of the evidence of clenbuterol contamination in cattle occured during the 80's and early90's and gradually dissipated as knowledge of the dangers and lack of performance of the drug became clear.as well as other safer legal alternatives such as ear implants came to be known.
When details are searched in the cases i have seen quoted many times they either refer tothe all encompassing term "livestock"(such as horses) or cases that were far from recent.
Now every time i hear of beef with clenbuterol i consider the source and question the accuracy. Is it a country with lax safety standards? Is it a country where consuming horses is a possibility? And if so, could the fact that it takes place in such a country be that it might be somewhat of a safe haven for that behavior?
any country such as Spain which conducts thorough testing of its beef(domestic & imported)and has no recent positives would obviously not be a place where clenbuterol contamination has any reasonable chance of occurring.
And before someone mentions AC lawyers contention of percentage of testing
producers do not sell just one cow so they have tens of chances if not hundreds per year of having their beef tested. And the accuracy of tests they were doing 15 years ago could trace clenbuterol use going back months, i would imagine current testing would be even more advanced.
So over a period of years even a low percentage of overall tests would still result in a great chance of having ones cattle detected for ANY clenbuterol use, with quite severe penalties for being found in violation of the law.
I would imagine in the last 5 years the chances of a cattle producer in Spain not having their product tested is slim & none.
While innocent until proven guilty is the acceptable standard , once you become positive, for any amount you are guilty. The burden of true proof (and not just possibilty) to reestablish innocence is almost impossible to achieve, because, if you allow the use of probability and possibility to substitute for the hard facts that were used to establish guilt, there is too great a number of possibilities to disallow guilt.
As an example the innumerable drug combinations possibile but as yet unresearched.
zero tolerance with no exceptions IMO
all these substances are used on humans and animals for respiratory problems.
With a search for "drugs in drinking water" dozens of things come up, domestic and international studies that find all kinds of things in high concentrations. Finding a common asthma medication in young people athletes or not would hardly be a surprise. I think Poland and China have Mexico beat for horse meat on the table.
