“A recent spate of dog deaths in Victoria has been traced to a consignment of horses transported from the Northern Territory to be processed for pet meat, according to Primesafe and Agriculture Victoria. A statement released by the two organisations late last week said test results had confirmed pet meat processed at the Maffra & District Knackery Pty Ltd of Wombat Road, Boisdale, also known as Maffra District Knackery, as the source of indospicine, which caused the recent cluster of liver disease and dog deaths in Victoria.
Since the end of May, Victorian government agencies have been made aware of 61 affected dogs, of which 21 have died. These cases are predominantly in Bairnsdale, Traralgon, Mornington Peninsula and eastern suburbs of Melbourne areas to date. On 23 July, indospicine was confirmed as the toxin causing the illness and deaths.” https://www.beefcentral.com/news/dog-deaths-linked-to-contaminated-horse/
