I heard a distant bell ringing with this story. Finally found the one I remembered from a year ago.

From soil in Haiti, hopes for antibiotic

With doctors increasingly worried about "superbugs," deadly infections that can defeat most known drugs, a small Cambridge biotechnology firm has won $70 million in venture capital money to develop a powerful antibiotic from a microbe discovered in Haitian dirt...

..."You've got the Darwinian battle going on under the ground in Haiti," said Targanta chief executive Mark Leuchtenberger . "Somehow, this became the don't-mess-with-me microbe."
I'm NOT saying "Forget about the poverty dirt cookies.". Those conditions are deplorable, and it's outrageous that anyone in our own hemisphere has to resort to such drastic measures, when there is such opulence all around.

But, maybe there's a bio-chemical reason that such a menu doesn't kill the "diners" over time.
