Mold in a juice box


Kids’ juice boxes can breed mold when the drinks don’t contain preservatives

St. Louis Post-Dispatch

What’s grosser than gross? Slimy green mold growing in kids’ juice boxes. When the drinks are preservative-free, defects in the packaging can allow oxygen in and fungus to grow.

One concerned parent recently took a Juicy Juice box filled with mold to St. Louis Children’s Hospital. The juice was not past its expiration date, and the child who drank it had no symptoms.

The local incident was the only complaint from that batch of juice boxes from the factory, according to a statement from a Juicy Juice representative.

“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,” said Shannon King, a manager at Nestle. “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.”

Moldy or fermented juice is not particularly dangerous to drink, said pediatrician Dr. Kathleen Berchelmann of St. Louis Children’s. But she took the opportunity to advise parents against giving juice to kids because of its sugar content and low nutritional value. The American Academy of Pediatrics recommends kids eat whole fruits over fruit juice.

“For me as a pediatrician, this is an opportunity to catch people’s attention and talk about that kids really shouldn’t be drinking their calories,” Berchelmann said. “Juice is not a health food.”

The problem is not just with Juicy Juice, advertised as 100 percent fruit juice. An Indiana State biology student from St. Louis recently found five types of fungus in Capri Sun packaged drinks as part of a research project.

Leah Horn spent her senior year using a vacuum to filter the drinks and search for fungal microbes. She found three species of fungus in the tropical punch flavor and one each in the roaring waters and fruit punch flavors. Horn has since graduated and could not be reached for comment.

On its website, Kraft Foods answers questions about mold found in Capri Sun drinks, which are also free of preservatives. The company acknowledges occasional complaints of mold among “many, many millions of pouches we sell each year.”

The company has added a disclaimer to its cartons about tossing any damaged or leaking pouches, while acknowledging that microscopic holes don’t cause leaks but allow for mold to grow. An attempt at transparent juice pouches caused too many manufacturing problems, according to Kraft.

The company states that the mold in Capri Sun is similar to that found on bread and cheese and other foods, adding:

“And yes, it can be ugly, gross and totally unappealing. It would be great if foods stayed fresh forever. But the basic laws of science and nature dictate that most foods eventually spoil and get moldy.”
