Dead dolphin tests positive for H5 bird flu

South Australia has confirmed 340 instances of bird flu, following a positive test result in a common dolphin. The frequency of positive detections has decreased. A vaccination program at Cleland Wildlife Park and Zoos SA sites is set to expand to wild little penguin populations in three locations. Another dolphin has tested positive for H5 bird flu.

South Australia's chief veterinary officer, Skye Fruean, stated that the case involved a common dolphin that washed up at Encounter Bay on the state's Fleurieu Peninsula this week. She noted that there is a low risk of a widespread outbreak among dolphins, although there are concerns for land-based sea mammals such as seals and sea lions.

According to Dr. Fruean, the dolphin likely came into contact with an infected wild bird. There is no expectation of a large dolphin mortality rate due to bird flu. South Australia has recorded 340 positive H5 bird flu events, with each event encompassing confirmed positive tests affecting at least one animal from a species at a single location.

Dr. Fruean expressed satisfaction with the recent slowdown in positive cases, though they are still consistently observed. Significant deaths have not been reported in any recent events. The crested tern population has experienced notable impacts, particularly. A vaccination program for selected birds at Cleland Wildlife Park and half of it for birds at Zoos SA facilities has been completed.

The federal government has authorized the release of vaccines for a little penguin program in South Australia. Dr. Fruean mentioned that preparations are underway to commence the little penguin vaccination program in penguin colonies located on Granite Island, Penneshaw, and Emu Bay. The start date for the little penguin vaccination plans has not been determined, but the operational work continues.
