Regulatory Testing  

Why should fair management test for drug residues in livestock?

  • One reason is to assure the public that 4-H and FFA exhibitors are producing a safe wholesome product that can safely be consumed. 
  • The second goal of this regulatory exercise is to insure that no illegal drugs were used with these market animals.

How do you insure that the regulatory testing process is not compromised?
Assure a chain of custody throughout the process. It is recommended that a trained volunteer or veterinarian collect, store and maintain custody of the sample. The sample is collected, labeled with the animal’s information and sealed. The samples are then kept in a container which is sealed shut between sample collections. A veterinarian will maintain control over the sample container. The samples maybe refrigerated in the container prior to being delivered to the lab.

What samples will be collected?
The collection of urine is more beneficial than collecting blood, although both work. Generally, urine is collected from cattle, sheep, goats, pigs and rabbits although drawing blood would suffice if there were time limitations. 
In the case of poultry collection of a fecal sample is necessary, but be sure to not get environmental contamination.

Urine sampling technique
Using a urine cup on a stick greatly facilitates urine collection  Have lid unscrewed and left in place to reduce environmental contamination.  This will insure you can respond immediately after the animal exits the arena and returns to its stall. If you miss the initial urination it might be 1-4 hours before the animal may need to urinate again. Work with your fair veterinarian to get the proper equipment.
