As a result, 13 crates carrying the creatures - which were technically not eels but hagfish - hitting a vehicle and causing four others to shunt into it. There were no major injuries, though several vehicles suffered damage and became engulfed in the slime.
Mr Tragale's load of hagfish were destined for South Korea where they are enjoyed as a delicacy.
The Oregon Department of Transportation warned travelers of delays as the highway has been shut down to one lane in the area of the crash. Video shows crews using bulldozers to clear eels and slime from the roadway.
And, of course, that they don't get overturned and left on Highway 101.
"In this heat... what is this going to start smelling like in the next few days?" the Oregon State Police tweeted.
An eyewitness, Erin Butler of McMinnville told FOX 12 that the scene was unbelievable.
"[I'll remember] the sliminess of it all", she said, adding, "I will never eat eel". Tragale has not been charged at this time, but police say that charges are pending.
Hagfish can be found dwelling at the bottom of the Pacific Ocean and are harvested off the coast of Oregon.
The task was surely not easy, as the Oregonian points out that "Hagfish slime - a type of mucus - can expand to more than five gallons when combined with water". "People always find ways to be grossed out by odd marine creatures, but when you think about it, hagfish are magnificent".
