It's quite a stretch to think that out of all the billions of chicken nuggets made, they happened to pick the only two, from two different sources, that contained blood vessels, nerve tissue and bone. If you were looking for trace amounts of something a larger sample would surely be required, but a sample of two is good enough to determine the basic elements that go into the product.
In Zyglo's example, you might have to examine a hundred crankshafts to find out if there was a recurring manufacturing flaw, but you would only have to examine one or two to conclude that they are generally made of steel.
