Petroleum product toxicosis can be caused by ingestion of, inhalation of, and/or dermal contact with petroleum hydrocarbons in crude oil, gasoline, diesel, kerosene, naphtha, or other hydrocarbon mixtures. Clinical signs can include respiratory distress and aspiration pneumonia, generalized GI disturbance (eg, salivation, bloat, diarrhea and/or constipation, anorexia and weight loss), CNS depression and/or excitation, impaired reproduction, and death. Identifying and obtaining a sample of the petroleum product and samples (feces, stomach/rumen contents, lungs, fat [especially perirenal], liver, brain, and other tissues) from affected animals are important to match the hydrocarbon "fingerprint" in the source material to the biological tissue. Treatment is to stop the exposure and remove the animal from a contaminated environment, feed, or water. Prognosis depends on the animal and the type of hydrocarbon product, as well as the dose and duration of exposure.
