Council investigates dog deaths linked to Townsville beach
Vets are mystified and say the only common factor is the dogs had been playing with coconuts found in the sand.
Veterinarian Alistair Graham-Evans said the three family pets died from acute liver failure this week, falling ill hours after separate visits to the Pallarenda dog beach in Townsville.
"Tragically they have all died despite intensive care," Dr Graham-Evans said.
"The common factor to all three is that they were all on Pallarenda dog beach and all three were eating, chewing, or playing with coconuts."
Dr Graham-Evans said his team alerted authorities who were investigating possible toxic exposure to beach coconuts contaminated with blue-green algae.
He said the exact cause of death could only be proven through a post-mortem exam, which the dogs' owners were reluctant to authorise.
James Cook University PhD candidate Joseph Perkins said it was possible microorganisms such as blue-green algae, stemming from a larger algal bloom, had attached onto the coconut fibres.
"The cyanobacteria, they're microscopic organisms and they're natural within the environment and under certain conditions they can rapidly grow and cause these algal blooms," he said.
"It seems like what's happening with this tragic incident is that it could be through contact with these microscopic organisms."
Mr Perkins said water sample tests could determine if there was an algal bloom off the coast.
A Townsville City Council spokesperson said in a statement it was investigating the matter and would update the community as soon as possible.
Dr Graham-Evans said he urged pet owners to be cautious about the exposure risk.
"To our knowledge, three dogs have been affected and the circumstances are similar enough to issue a warning," he said.

TGA concedes it failed to prevent growing number of blood toxicity cases attributed to Vitamin B6
Australia's medicines regulator has conceded its laws have failed to slow a growing number of blood toxicity cases attributed to a common over-the-counter vitamin. The Therapeutic Goods Administration (TGA) also admitted some associated effects — including irreversible nerve damage — are a bigger problem than the agency first realised. "The [legislation] changes from a few years ago, we've seen, were not sufficient to reduce the rate of the level of toxicity from B6," the department's chief medical advisor Professor Robyn Langham told 7.30. In its manufactured form Vitamin B6 — often labelled pyridoxine, pyridoxal, or pyridoxamine — is added to thousands of Australian products including foods, energy drinks, diet shakes and supplements. Overconsumption of the synthetic vitamin can cause life-altering issues including peripheral neuropathy, a nerve damage complication causing tingling, numbness, burning or weakness in limbs. "It's just shocking," said clinical pathologist Dr David Kanowski, who runs a clinic testing B6 blood samples from across Australia. "Sometimes we talk to doctors who think it's a clerical error because the toxicity results are so high, and we say, 'No it's real, you need to sort it out,'" he said. Dr Kanowski has noted a "massive" increase in the number of people coming forward for B6 blood tests; doubling since January to more than 10,000 each month. Looking at the data for May, he said 4.5 per cent, or 450 people, returned results showing they were "very likely" to develop a neuropathy. A quarter of the samples, or 2,500 people, would "possibly, but not probably" also be showing symptoms. "One big lot [of cases] was caused by magnesium supplements, and I think it was possibly added as filler," Dr Kanoski said. "I'm not sure the technical reasons why it was there." The TGA is responsible for approving the ingredients used in complementary medicines in Australia. B6 is registered in more than 1,500 over-the-counter supplements — from magnesium to multivitamins. Eighty per cent of them contain levels well above the recommended daily amount of 1.7mg. 7.30 asked Blackmores Group, one of Australia's biggest supplements manufacturers, why many of its products contain B6 in such high levels. The company declined an interview but said all its products "including those containing Vitamin B6, are developed in strict accordance with the regulatory requirements of the TGA". While its own interim report found "the benefits of supplemental intake of vitamin B6 to be negligible", the TGA now joins the list of organisations which could not or would not say why B6 is added to so many products. "I'm not really able to answer why the commercial decisions are made by the different sponsors," Professor Langham said. She was quick to defend the TGA's "regulatory frameworks" as "very robust". "They exist so that the safety of the Australian community is held right at the centre of everything that we do," she said. After months of pressure to act, the agency handed down several recommendations on Friday, based on the advice of a committee tasked to investigate the burgeoning B6 problem. It was critical of the complementary sector, describing product labelling as "inconsistent and confusing", and called for clearer information and the rescheduling of supplements containing more than 50 milligrams of the vitamin, which would move several products off shelves and behind counters. "That will give the Australian community more protection and a greater sense of safety," Professor Langham said. The TGA last tightened the rules around B6 in 2022, requiring supplement companies to put warnings on products with more than 10mg. But many sufferers and medical professionals say they didn't go far enough. And there are new concerns that the latest round of proposed changes won't prevent toxicity for people taking multiple supplements at once. "It could still easily be an overdose over a period of time, if you're taking three or four complementary medicines with lower dosages," community pharmacist Caroline Diamantis told 7.30. The complementary medicines sector argues that B6-related incidents are "extremely rare", according to Complementary Medicines Australia boss John O'Doherty, "based on a comparison of sales data with the TGA's public database". While that data shows more than 170 adverse events, the TGA's Professor Langham said it could not be used to make that case. "I think it's sufficient to say that our database of adverse events doesn't necessarily reflect the true incidence of what's happening in the community," she told 7.30. "It's also important to understand that because something is reported, it doesn't necessarily mean that there's a definite attribution of cause there." Ms Diamantis is also concerned the proposed implementation of the TGA's regulatory changes, February 2027, "is too far away". "Personally I feel like that's too long, because there's another year or more where people could still be experiencing side effects," she said. Professor Langham said the complexities of the changes means the process "is a long one". "We're going to have to look at reformulating their products, which will mean either transitioning them out of the market or reducing the dosage that's in there," she told 7.30. "And there's also another element of changes that the TGA is looking to make from a legal perspective to our legislation around some of the labelling and also around some of the lists of medicines, what we call our permissible ingredients list. "It's done so that things can be done carefully and properly, and so that Australians can feel confident, ultimately, that the correct decision is being made." The TGA will accept submissions on its "interim decision" until July 27 2025, which will be considered by a senior medical officer before a final decision is made.

NSW man in hospital with state's first confirmed case of Australian bat lyssavirus
A northern New South Wales man is in a critical condition after contracting the state's first confirmed case of Australian bat lyssavirus. Keira Glasgow of NSW Health said the man, aged in his 50s, received treatment after being bitten by a bat several months ago. "Unfortunately he's recently developed symptoms of lyssavirus … which is incredibly rare," she said. Ms Glasgow said there was "no effective treatment" for the illness and that an investigation was underway to establish whether other exposures or factors contributed to the man's infection. It is the fourth case recorded in Australia. Ms Glasgow said lyssavirus was a "rabies-like infection" transmitted from infected bats to humans via a bite or scratch. The virus affects the central nervous system and is often fatal. "This is a tragic situation," she said. NSW Health is reminding the community to avoid touching or handling bats. "There are people who are trained and fully vaccinated and protected who are able to handle bats," Ms Glasgow said. "The best thing you can do is to call your local wildlife carers agency to help you." She said anyone exposed to a bat bite or scratch should seek urgent medical attention. "You should wash the wound thoroughly for 15 minutes right away with soap and water and apply an antiseptic such as Betadine," Ms Glasgow said. "You will then require treatment with rabies immunoglobulin and rabies vaccine."
