Well, assuming you're healthy it is sterile
Just remember if I can detect urine using an FDA approved test it's not statistically insignificant.
The catch with your moral code is that you are legally required to test for transfat using an FDA approved test. If it contains less than 0.5g or is undetectable by the approved method you use, you are legally required to print contains 0g transfat.
So do you shutdown/sell Great Grandad's fishstick business and donate all the proceeds to heart research?
The only way to get them to print more precise labels is to change the stance of the FDA.
