A New Jersey high school's food vendor says it's investigating after several students began circulating video purporting to show a live insect squirming inside a taco salad school lunch.

Video taken by North Bergen High School students show what appears to be a small worm on the lunch plate. One girl posted the video on Instagram, and another boy sent video to NBC 4 New York.

The authenticity of the videos could not be immediately confirmed Friday, but the lunch vendor for the school, Nu-Way Concessionaires, said it's investigating and that the health department was immediately called in.

"This is an isolated incident. We've taken steps to discuss this with our food producers. We are very concerned about what we feed children," said Sal Valenze of Nu-Way Concessionaires.

One student, Luis Godreau, said "I would think they would make sure nothing like that would get inside it. It's crazy to see that inside it."

Another junior student who wanted to remain anonymous said a freshman made the gross discovery and brought the video to the school's main office.

Nu-Way officials say they believe the insect was a small worm, and though rare, insects can get into produce during the agricultural process.

As a precaution, the product batch has been pulled from distribution. The USDA is also expected back at the school Monday to continues its investigation, Nu-Way said.

Calls to the school district and the North Bergen Health Department were not returned Friday night.
