Visability and stench problem on the freeway(fog like)

As you drive away from the Brawley outskirts and are turning on the corner on the freeway there is a cattle lot on the left which there was a fog emitting from the lots that was covering the highway and for around 1/2 mile or more a visabilty problem and a very bad stench from the fog which was emitted through the vents of the A/C of the car. Concerned about the contamination of these toxics to the homes nearby and the visabilty for the travelers in that area that are not warned about the fog ahead.
