oil-contamination

It also blocks nares, causes aspiration pneumonia, and has toxic effects on kidneys, reproduction and the gastrointestinal tract.

crops grown primarily for their oil production, e.g. linseed, safflower, sunflower, rapeseed.
crude petroleum oil
crude oil and its several distillates are all relished by cattle and can cause poisoning. The oil as it is extracted from subterranean deposits varies widely in its additional contents. These may be salt or sulfur and cause poisoning by those substances. Oil causes vomiting and death from aspiration pneumonia.

includes kerosene (or kerosine, or paraffin), gasoline (or petrol), diesoline and additives to lubricating oils, e.g. highly chlorinated naphthalenes; any of them may cause poisoning.
oil spill
