Hi,
Recently we had Res. Grand Steer at our state show. Customary urine samples were taken. Upon review, elevated levels of sulfamethazine(antibiotic) were found. Our show cattle were treated for coccidiosis the 2nd week in October. I keep very detailed records of all treatments, etc. They were given Sustain III boluses. The listed withdrawal is 12 days. The urine tests were taken the first week in Feb. which is way beyond the 12 days. How can I possible find out what could have caused this? I have already contacted the manufacturer of Sustain. I am not looking to place blame by no means, I am simply looking for possible causes of the elevated levels in the steers body. Any help would be greatly appreciated. The sooner the better. We are to meet with officials next week and I want to be as prepared as possible. I have looked all over the internet and copied papers, but none have really valid reasons.
Thank you so much,
