In Bernard v. Louisiana Wild Life and Fisheries Commission, 152 So. 2d 114 (La. App. 3 Cir. 1963), plaintiff recovered compensation for occupational diseases, chemical pneumonitis and emphysema, caused by his inhalation of the chemical spray 2-4-D. Neither disease was specifically listed in R.S. 23:1031.1, and neither was the pathogen, 2-4-D (Dichlorophenoxyacetic Acid), but plaintiff was awarded workers' comp benefits under R.S. 23:1031.1. There was no discussion as to the chemical properties of 2-4-D, other than it was toxic and an irritant, but implicit in the court's analysis is the fact that 2-4-D was a listed compound.
