O'FALLON, Mo. (KSDK) - If you're eating or drinking right now, especially a juice box, you might want to set it down for a moment.

A non-edible, disgusting slime was found in a child's juice box, and is prompting a warning from doctors at St. Louis Children's Hospital.

A thick green mold coated the edges of the box and the O'Fallon, Mo. mom was worried it was going to make her 10-year-old daughter sick.

" Iwent on line and started looking stuff up and found out it was mold and I wasn't sure if it was toxic soI took her to the emergency room," said Julie Herbert.

Doctors say, the mold is nothing new. If a tiny bit of air gets into a juice box through a microscopic hole, sugars ferment, not only turning the product into a form of alcohol, but since there are no preservatives, it permits mold to grow.

The good news is that moldy juice isn't life-threatening. It can give you an upset stomach and totally gross you out, but it won't kill you.

Still, doctors are recommencing cutting juice out all together. Why? Because juice is so full of sugar and calories that some have called it a gateway drug to obesity.

"You have to ask yourself, do your kids really need this? and the answer is no." She added, Kids just don't need the sugar of juice. People say it's so much better than soda. Well, it doesn't have artificial stuff soda does, but it still has the sugar, and what's wrong with water? That is the take home lesson," said Dr. Kathleen Berchelmann, a pediatrician with St. Louis Children's Hospital.

Shannon King with Nestle, USA issued the following statement: "We completely understand the concern about mold and assure our consumers that the safety of our products and health of our customers, especially the children who drink our juice, is of the utmost importance to us. Juicy Juice does not contain any artificial ingredients or preservatives and spoilage can, in very rare circumstances, occur if the packaging was damaged in any way and due to the natural sugars in juice. There have been no other mold complaints for this date code or similar date codes from the same factory for this product. We believe this was an isolated incident."

The American Academy of Pediatrics offers this guidance regarding kids and fruit juice:
Never serve your kids unpasteurized juice.
