Regarding contamination in horse racing tests...
1-ounce of coffee equals 12 million nanograms of Caffeine.
However, only 100 nanograms of Caffeine are needed to trigger a 15-day suspension for the trainer and disqualification of purse.
Basically, one sip of coffee is enough to put a race horse 120,000 times over the testing limit for caffeine.
Considering that caffeine is commonly consumed around race horses (coffee, soda, chocolate bars, etc) why don't we see more cases of bad caffeine tests via contamination?
Patrick Biancone got a 15-day suspension for a Caffeine overage -- and a related search of his barn found Cobra Venom. I guess he probably could've argued that the bad test for Caffeine was a contamination, if not for the fact that the search nabbed him for Cobra Venom.

For general sports fans, it's easy to be pessimistic. How stupid does this Nike commercial look now?:

Here's a 10-second clip of a supposedly straight-shooting guy waiving his finger at Congress:

Aaron Rodgers was so sure Ryan Braun didn't cheat -- he offered to bet his $8.5 million salary on it:

Of course, Braun somehow won with his 'contaminated urine sample' defense. But he got busted for PED's again, not long after that.
With human athletes, we've come to accept that "where there's smoke, there's fire" and claims of contaminated tests are usually mocked.
