Detection of flunixin in the urine of untreated pigs housed with pigs treated with flunixin meglumine at labeled doses.

The objective of this study was to determine the likelihood that swine treated with flunixin meglumine could contaminate their environment, which could cause untreated swine housed in the same pen to ingest or absorb enough drug to be detected in their urine. Currently, any detectable level of flunixin found in the urine of pigs exhibited at livestock shows in Texas can disqualify the exhibitor. We conducted 2 trials in this study.
