title: Unstable injectable selenium treatments that may be toxic to cattle.
abstract: High or toxic tissue levels of selenium resulted from administration of the aqueous layer of an unstable injectable oil emulsion of selenium and vitamins A and D. Since selenium partitioned from hydrophobic to aqueous media in the poorly mixed product, the aqueous portions constituted a significant threat to health.
