My Prius broke wind

You are talking about a smell, or a farting sound? If it was a smell, it's probably from outside.

Check your 12V battery for leaks.
Check your cabin air filter.
Change brands of gas.

 

Check front right tire for black & white skunk hair.

 

was your air on recirc?

 

Are you sure it wasn't just something from outside the car? I could see something hanging inside the car for a while. And, if you put the air into recirculate to prevent the outside odor from entering, you'd also delay its clearing from within the car.

It could have been something spilled near the roadway, or something that leaked near the road.

 

If you were travelling in a rural area it could have been a farm which was recently sprayed or spread with fertiliser which can really stink. Apart from that I don't know.

It wouldn't hurt to check the 12v battery.

 

I recently ran over a road-kill skunk. I didn't hit it with any of the tires, just straddled over it and didn't touch it with any part of the car. Nevertheless the smell lingered in the car for a few days. So I know that can happen.

I also think the smell you detected came from outside.

The only other explanation might be the emission suppression system; I have been near cars that were emitting hydrogen sulfide (rotten egg smell). But usually they do that all the time and it's a sign that something is not right with the car. And I think that was a hazard of a particular generation of cars; I would be surprised if any modern cars ever do that any more.

 

Got a similar experience before driving other car.

See a fresh dead skunk on the road in the morning commute (skunk stinks!), and by evening the smell is still lingering the same spot even it has been removed. (Guess people complaint too!)

Takes almost 3 days before that section of the road back to normal, guess the light rain did help cleaning up the smell.
This skunk stinky thing is pretty strong if it gets hit in the right part.

 

Were you anywhere near a sewage treatment plant? Presumably you would know that if the route is familiar, but maybe not if the prevailing winds normally have you on the upwind side.

There is a treatment plant just to the east of I-95 in Richmond, VA that I normally don't smell. But in the unsual case where the wind is out of the east, the aroma is gosh-awful for travelers.

 

I like ham sammitches as much as anyone, but my suggestion is that you drove by a pig farm. The farm could have been 3 hills over; the road wouldn't have had to be right next to the pig farm.

Trust me on this.
