A semi-truck hauling a trailer full of salmon heads and guts intended for cat food spilled its load on U.S. 101 north of Ilwaco.

Washington State Patrol Trooper Russ Winger says the "soupy" cargo apparently started sloshing around on a curve and caused the trailer to tip over Friday, closing the highway with the slimy mess.

The truck cab remained upright, and the driver was not injured.

An excavator was brought in to scoop up as much of the spill as possible. The rest was practically on the shore of Willapa Bay near the Willapa National Wildlife Refuge. Winger said it would make a banquet for seagulls and crabs.

The truck was carrying the salmon leftovers from a rendering plant to a cat food factory.
