New Zealand's Cambridge Stud on Thursday issued a statement from CEO Henry Pumptre regarding the suspect positive test result for the disease Theileria equi that was returned as part of standard export certification testing of a Cambridge Stud mare prior to shipment from New Zealand.
We have been notified by the New Zealand Ministry for Primary Industry (MPI) that, following a routine pre-export blood sample analysis, a Cambridge owned broodmare is suspected of carrying Theileria equi, one of the causes of piroplasmosis.
The mare in question was imported under New Zealand protocols last year from France as a maiden and has been resident at Cambridge Stud since her arrival in February 2019. She was purchased at the Arqana sale in December 2018, was negative in a pre-sale test, was negative prior to going into quarantine and was negative under New Zealand protocols, before departing the U.K.
She was due to visit an Australian stallion this year and was tested, along with nine other Cambridge mares, last week. We were informed of a possible positive and we immediately requested a second sample which is being tested this week. The implication is that she will be positive again.
We are working with the MPI and our own vets at Cambridge Equine to test every mare at Cambridge Stud. Fortunately the mare in question is known to have had direct contact with a very small number of horses, and given the main means of transmission by tick, the likelihood of further infection is considered very low. However, we have taken the cautionary route with the MPI and will test every horse on both properties at Cambridge and Karaka.
It is our intention and that of the MPI to work through the testing process as quickly and efficiently as possible, given the restraints that have been placed on our industry in the past 24 hours. There will be a further update as soon as we have the results from mares that will be tested today at Cambridge and tomorrow at Karaka.
