Strangles
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.
