Transportation Security Administration officers found an 8.5-inch knife in an enchilada carried by a passenger trying to board a plane at the Sonoma County airport.

The knife, which was inside some enchiladas wrapped in aluminum foil, was discovered Monday morning in a passenger's carry-on bag at the Charles M. Schulz-Sonoma County Airport, a TSA spokesperson tweeted. The enchiladas appeared to be homemade, according to the TSA.

The passenger was cleared to fly, the spokesperson said. It was not clear why or how the knife ended up with the enchilada.

Jon Stout, manager of the airport, referred questions about the knife to a TSA spokesperson, who was not immediately available.
