CARLSBAD, N.M. (KRQE) – A bag of Cheetos that was dropped on the ground at Carlsbad Caverns National Park had a large impact on the cave’s ecosystem, according to National Park Service staff.

“At the scale of human perspective, a spilled snack bag may seem trivial, but to the life of the cave it can be world changing,” an NPS official wrote on Facebook on Sept. 6. Staff said the bag was found off-trail in the Big Room. The processed corn in Cheetos was softened by the humidity of the cave and “formed the perfect environment to host microbial life and fungi.”

This in turn attracted cave crickets, mites, spiders, and flies, which then spread the mold to nearby surfaces. “Molds spread higher up the nearby surfaces, fruit, die and stink. And the cycle continues. Rangers spent twenty minutes carefully removing the foreign detritus and molds from the cave surfaces,” according to the post.

The park’s rules say that the only food that can be consumed in the caves is unflavored water. Food and any other drinks are prohibited. Park staff encouraged visitors to be mindful of their activities to prevent things like this from happening.
