New Zealand

On 16 January 2019, Promed reported an outbreak of strangles at a pre-export facility in New Zealand, which resulted in a consignment of horses being prepared for export to Hong Kong not meeting the requirements for certification. A total of four horses were initially confirmed positive, amongst a group of 30 horses in total. The horses were due to travel to Hong Kong in July 2018, but tested positive during routine testing, halting the Post Entry Quarantine (PEQ) process immediately, in accordance with Hong Kong Jockey Club procedures. Since then, 12 of the 30 horses have met entry requirements and travelled to Hong Kong in September 2018. There are still 17 horses in quarantine and 4 more of these horses have since tested positive and been isolated. A spokesman for the New Zealand Ministry of Primary Industries (MPI) confirmed the outbreak. It is now intended for the remaining horses to be exported from New Zealand by the end of this month (January 2019), pending an inspection and approval.


The Michigan Department of Health and Rural Development has confirmed three separate strangles events in the state. The first involved a five-year-old Quarter Horse gelding in Jackson County. It was reported with a nasal discharge and fever on 14 December 2018 and was cultured positive for the disease. The horse has since recovered. The second outbreak involved 15-year-old Arabian mare in Washtenaw County that had an almost two month history of a cough and feed coming from its nostrils. The mare was subsequently cultured positive for strangles. The mare remains under treatment and the premises where she is located has had additional cases of strangles confirmed this year. Vaccination history against strangles cannot be confirmed. The third event involved a seven-year-old Quarter Horse gelding in Monroe County. On veterinary examination on 28 December, the gelding was found to have a nasal discharge of indeterminate duration. A diagnosis of strangles was confirmed. The horse had not been vaccinated against the disease and is recovering. No quarantines have been imposed on this premises. The latest cases bring the state’s total of cases of strangles to 22.
