We just got back the test results from a bottle of Dasani water. It's confirmed the substance inside is infact a type of mold. And while Dasani says all the bottles should be off the shelves, I suggest looking at your bottled water very closely before you take a gulp. Just to eliminate the chance of getting sick - not from the mold itself - but from the "yuck factor"!
If you happen to have one of the bottles.. you can contact Great Plains Coca Cola at 800-753-COKE.
