Testing for Prohibited Substances in Rural Agricultural Show Exhibits: A Twenty-Three Year Experience

Area of Science:

• Veterinary pharmacology
• Animal welfare science
• Sports integrity

Background:

• Prohibited substance administration in animal competitions undermines fair play.
• Detection of illicit drug use is crucial for maintaining ethical standards in animal sports.

Purpose of the Study:

• To prospectively investigate drug testing outcomes in four animal species over 23 years.
• To identify commonly detected prohibited substances and compare testing strategies.

Main Methods:

• A large-scale, prospective descriptive study involving 1,598 animals across four species.
• Analysis of drug testing results from both random screening and targeted testing protocols.

Main Results:

• Overall, 4.7% of tested animals returned positive results for prohibited substances.
• Commonly detected drugs included acepromazine and phenylbutazone, often legitimate veterinary therapeutics.
• Targeted testing yielded a significantly higher positive rate (50%) compared to random screening (4.7%), though sample sizes differed.

Conclusions:

• Random drug testing effectively identifies a portion of animals using prohibited substances.
• The prevalence of both legitimate therapeutics and other drugs necessitates continuous adaptation of detection methods.
• Ongoing vigilance and research are essential to combat evolving drug use in animal competitions.
