From the same news story:

The FDA has determined that any detectable level of melamine makes it unacceptable for use in human or animal feed, he said.

And…

The FDA found melamine-related compounds in the raw ingredients but, in the processed feed, only at levels too small to quantify, he said. The health risk to animals and humans is considered low, so the agency allowed the feed to be sold, he said.

Does that sound like a contradiction? Any detectable amount is too much, unless it’s too small to quantify, which makes you wonder if you can’t quantify it at all, then how do you know it’s there? If you can tell there is melamine in it, then that would be “any amount”, wouldn’t it … and thus it would be unfit for human or animal feed. That’s like saying “Oh, we found some, but it’s not much. Barely there, really. You’ll never notice it.”

Well, I don’t want ANY melamine in ANYTHING that ANY animal or human is consuming.

Because the three contaminated, imported ingredients also are used in a wide variety of human food — everything from baby formula to energy bars to gravy — the federal government launched an unprecedented food surveillance of human and animal foods. It is tracing where Chinese-bought ingredients went and plan to visit manufacturers nationwide to test ingredients and finished products.

The investigation is still in its infancy, and none of Pennsylvania’s 2,100 food manufacturers has been investigated yet as part of the surveillance.

So if they find anything, do you think we’ll actually hear about it? I don’t, unless it’s a little blurb in a larger story saying “Oh, yeah, there was a bit there, but it was such a small amount we believe the risk is low … so we allowed them to sell the product anyway.”
