A case of glanders was reported in the USA on 3 April 2015.
Due to the nature of the detection, the United States Department of Agriculture (USDA) still considers the USA free from glanders. Consequently, the veterinary certification for equine semen from the USA to New Zealand is not affected.
The IHSs for horse semen from the USA and Canada currently require testing for Taylorella asinigenitalis and Taylorella equigenitalis when donors have not spent their whole life in the USA or Canada.
The causative agents for both these diseases are identical, therefore a negative test for Taylorella equigenitalis is sufficient to declare an animal free of Taylorella asinigenitalis.
Regarding clause 4.4 of the Veterinary Certificate:
The antibiotic combinations, at the concentrations listed below, have been accepted as equivalent to the Import Health Standard requirements, and may be added to the semen after final dilution.
• Ticarcillin at 1.2 mg/mL
• Ticarcillin at 1.0 mg/mL and Amikacin 0.5 mg/mL (Timentin® at 1.0mg/mL)
• Gentamycin at 50 mg/L
All other requirements of the IHS must be met.
