Tetracycline hydrochloride-medicated water samples taken from commercial farms were found to darken to yellow or brown. Tetracycline hydrochloride from collected samples was quantified by high performance liquid chromatography and assessed for its biological activity. Samples were biologically active in the expected range, but safety could not be determined.
