Salmon company Huon used tonne of antibiotics in bacterial outbreak, EPA report finds
Samples of wild fish caught near a Huon Aquaculture lease in February were found to have antibiotic residue levels up to a dozen times higher than the threshold for commercially sold salmon, according to an Environment Protection Authority (EPA) report.
The interim report monitoring Huon's antibiotic use was completed by environmental consultants Aquenal.
According to the report, 1,133 kilograms of the antibiotic Oxytetracycline (OCT) was administered via fish feed at Huon's Zuidpool lease between February 13 and February 26 this year.
In February, a mass mortality event caused by the bacterial pathogen Piscirikettsia salmonis devastated salmon farms in the D'Entrecasteaux Channel, south of Hobart.
Between January and March, the death of more than 13,500 tonnes of salmon was reported to the EPA by the three major salmon companies operating in the state.
By late February, Huon's Zuidpool lease had begun to draw public and media attention after the Bob Brown Foundation released drone footage showing workers at the lease putting live salmon into tubs along with dead stock.
Oily globules made of salmon fat began washing up along beaches on the channel, which were found to contain low levels of antibiotics.
According to the Australian New Zealand Food Standard Code, salmon destined for sale must comply with an antibiotic maximum residue limit (MLT) of 0.2 milligrams per kilogram.
The report said eight samples of wild fish were taken in the Zuidpool North lease, with three samples — all blue mackerel — testing above the reporting threshold.
It found one sample site with wild fish showing "relatively high" antibiotic residue levels of up to 2.4 milligrams per kilogram, or 12 times higher than the maximum antibiotic threshold for commercially sold salmon.
In a statement, Tasmanian Public Health Director Mark Veitch said the results were consistent with estimates used in a Food Safety Australia New Zealand (FSANZ) risk assessment.
"These samples were collected in late February 2025, in the days after the period of [antibiotic] dosing ended, when antibiotic residue was most likely to be present in fish and the environment."
The report also tested at Zuidpool South, with no samples returning antibiotic residue levels above the limit of reporting.
Samples were also taken at five locations several kilometres from the Zuidpool salmon pens.
One of those sites, Ventenat Point on Bruny Island, recorded noticeably elevated antibiotic levels in blue mackerel that was sampled.
Verona Sands, Jetty and Conleys Beach on Bruny Island, and Roaring Beach near Surveyors Bay were also sampled for antibiotic levels.
Aquenal said the results of those surveys will be released "in subsequent reports".
The EPA will release a final report with all sample results after the monitoring program finishes.
It raised concerns that prolonged exposure to antibiotic treatment could result in resistant bacterial strainers that were more difficult to treat.
This year the EPA would not disclose how much antibiotic was being used by Huon, citing commercial in confidence.
"If individuals are concerned at all about potentially having antibiotics in wild fish, then of course they can choose to fish further away from the [affected] lease," former EPA Tasmania director Wes Ford said at the time.
Antibiotics have been commonly used by salmon companies to treat bacterial diseases.
However, the EPA said antibiotic treatment has declined since 2009 due to the development of vaccines.
In 2022, Tassal used 675 kilograms of the same antibiotic to treat a vibrio outbreak at its Sheppards lease off the coast of Coningham.
Three flathead caught 2 kilometres from the lease were also found to contain more than the reportable threshold of antibiotics in their flesh that same year.

Landmark trial to enable energy trading between solar homes and those without
Maree Tynan knew that her cottage in Mittagong, in the New South Wales Southern Tablelands 110 kilometres south of Sydney, was the place for her more or less the first time she saw it. It was more than four decades ago and, in time, her and her late partner turned what was a getaway into their permanent home. During that time, Ms Tynan has seen her fair share of changes in Mittagong and in so many other ways besides. Among them has been the extraordinary rise of rooftop solar in Australia, where one in three homes now has the technology. It's long been something she's wanted, too. "We were very keen to be part of it, but we had two major problems," recalls Ms Tynan, whose home was built in the late 1920s. "The first is it's the original roof. That is terracotta. "As you can imagine, after 100 years in a very cold climate, it is very, very fragile. "Apart from the roof, we also have a lot of trees." Faced with those challenges, Ms Tynan feared she may have been locked out of the solar market for good. That was until she came across a project aiming to connect people who don't have solar panels with those who do. "To have had rooftop solar put on, we were going to have to have the whole roof replaced," she explains. "That just seemed crazy because, yes, we'd have solar, but we'd be spending an awful lot of money. "We decided that, while ever the roof was secure and not letting rain in, we'd stick with that and we'd look for alternatives. At its heart, the project aims to enable energy trading between solar households and those without the technology. Known as WinZero, the project is centred around the Wingecarribee Shire Council. Households taking part in the so-called virtual energy network are given a smart meter and hooked up to a scheme allowing them to buy from or sell to other participants in their local area. In order to participate, they must go through small, privately-owned electricity retailer Energy Locals, which uses third party software to handle the trades. Those without panels can buy surplus solar power for a rate lower than a standard tariff over the grid. Similarly, solar householders facing ever lower — or even non-existent — feed-in tariffs can yield higher payments for their exports. Now a new study based on the Wingecarribee model is being led by Deakin University, which is hoping to widen its scope to the entire national electricity market, which spans Australia's eastern seaboard. Of particular interest to researchers are consumers who don't or can't have solar panels themselves. Andrea La Nauze, an associate professor of economics at Deakin, says Australia might lead the world in the take-up of rooftop solar, but most people are still missing out. "We have the highest rate of rooftop solar in the world," Dr La Nauze says. "But there are many of us who are renters or live in apartments or for various reasons can't install solar panels. "First of all, it's expanding access to rooftop solar, which is good for the environment. "It's also hopefully good for the back pocket." As of last year, there were more than 4 million "small-scale" solar installations across the country. Under the definition in Australia, a small-scale installation can be anything up to 100 kilowatts, meaning many businesses with solar are also grouped with the category. However, most installations are on standalone homes and the vast majority of these are owned by their occupants, according to Dr La Nauze. She says virtual energy networks could be a way of bridging what is an inherent divide. By allowing customers with excess generation to sell it to those without panels, she says, both sides of the transaction might just end up winning. "Using the existing poles and wires, people who have excess energy from their rooftop solar can sell it to their neighbour or a local cafe," she says. "They can get more, hopefully, for that energy that they sell than they otherwise would. "And the cafe or the neighbour can buy energy at a lower price than their current retail contract." More broadly, Dr La Nauze says solar trading schemes could help answer a number of thorny questions hanging over Australia's energy transition. While equity in access to clean tech is one of them, she says the over-abundance of solar generation in the middle of the day is another. "We might also relieve some of the congestion that we have on the distribution network," she says. "The poles and wires in many parts of Australia are struggling because we have so much energy coming from rooftop solar in the middle of the day. "If we can encourage households and small businesses to soak up more of that power during the middle of the day, that's beneficial for the network. Michael Dello-Iacovo from Energy Consumers Australia, which is helping to fund the new trial, says the lobby group is keen to see how feasible an expanded network is. Mr Dello-Iacovo acknowledges the idea of trading might be an intimidating idea to some householders but notes the trial would be seeking to overcome this. "It ultimately comes down to the platform itself," Mr Dello-Iacovo says. "And so the platforms that I've seen for virtual energy networks … you can be as engaged as you like and there is an option to be very disengaged. "You can set up very simple trades to either sell electricity from your solar and battery or to buy electricity from someone else with solar or battery. "You can set up more specific trades and trade with an individual you know at a set price, for example. Although such networks are in their infancy, Mr Dello-Iacovo says the notional potential of "peer-to-peer" trading is enormous. He notes there are still millions of people in Australia who do not have access to solar power, making them a huge source of potential demand. "At Energy Consumers Australia, we advocate for all energy consumers," Mr Dello-Iacovo says. "And part of that means making sure everyone who wants to have access to consumer energy resources like solar and battery can have access to it. "So this trial is really exciting for us because there's a lot of potential for bringing those benefits from the energy transition to all households, not just those who are physically able to install solar and batteries." For Mittagong householder Maree Tynan, the scheme seems to be working. She acknowledges her electricity bills are generally modest anyway because she tries to limit how much power she uses. Even still, Ms Tynan says her costs are lower now. To that extent, she reckons buying other people's surplus solar power while cutting her bills is the next best thing to have some panels herself. Asked if she would be happy to keep doing it, she says: "Oh yes, I definitely will keep going while it's available." "I'd dearly love to have solar myself," Ms Tynan says. "But I can't see it happening anytime in the near future for the reasons I've explained." She says that for people in similar circumstances to her, the scheme should hold great appeal, especially if it can help save them money. "I'm very cognisant of what's happening in the world," she says. Along with Deakin University and Energy Consumers Australia, the new trial will be delivered in partnership with QuantumNRG, ReThink Sustainability and WinZero.

What the US warning on China means for our defence
Sam Hawley: Donald Trump is demanding America's allies massively boost defence spending. His Defense Secretary, Pete Hegseth, says a Chinese invasion of Taiwan could be imminent. And one of our closest allies, the UK, is rushing to invest billions of dollars in its defence force to make sure it's war-ready. Today Peter Dean from the United States Studies Centre at Sydney Uni, on what that all means for us, and whether our defence force is fit for purpose. I'm Sam Hawley on Gadigal Land in Sydney. This is ABC News Daily. Sam Hawley: Peter, we better start with these comments from the US Defense Secretary, Pete Hegseth, at the Shangri-La meeting in Singapore. He has warned that China poses an imminent threat to Taiwan. Pete Hegseth, US Defense Secretary: To be clear, any attempt by communist China to conquer Taiwan by force would result in devastating consequences for the Indo-Pacific and the world. There's no reason to sugarcoat it. The threat China poses is real and it could be imminent. We hope not, but it certainly could be. Peter Dean: Yes, so Secretary Hegseth I believe is referring to here is comments made by the Chinese leader Xi Jinping and by other members of the Chinese leadership, where Xi Jinping in particular has said that the Chinese military are prepared to use force and to achieve specific capability goals by the dates of 2027 and the dates of 2029. Pete Hegseth, US Defense Secretary: We know, it's public, that Xi has ordered his military to be capable of invading Taiwan by 2027. The PLA is building the military needed to do it, training for it every day and rehearsing for the real deal. Peter Dean: This is about requirements that Xi Jinping has set for the development of the People's Liberation Army and its subsequent Navy and Air Forces as well. So this is about its development of specific capabilities, but also its command and control systems, its ability to conduct exercises and its ability to conduct the types of high-end warfare to undertake, for instance, a strike across the Taiwan Strait. Sam Hawley: So what has China then, Peter, had to say about all of this, that it will imminently attack Taiwan? Peter Dean: Well, I mean, what Xi Jinping has said is that he reserves the right to use force to solve what the Chinese argue is a domestic political issue. They, of course, refer to Taiwan as a rogue state. They don't recognise the democratic system that the Taiwanese people have. And of course, they don't recognise the will of the Taiwanese people, who overwhelmingly identify now as Taiwanese and do not wish to be reunited with the mainland. Sam Hawley: Well, China's foreign ministry does say that the US is overstepping its bounds and stoking flames in the South China Sea in response to those comments from Pete Hegseth. Sam Hawley: Let's consider, Peter, now then China's military build-up and defence spending by Western nations. Now, our Defence Minister, Richard Marles, he also addressed that conference in Singapore, noting that Australia can't rely on the US alone to counter China's military strength in the Indo-Pacific. Richard Marles, Defence Minister: There is no effective balance of power in this region absent the United States, but we cannot leave it to the United States alone. Other countries must contribute to this balance as well, and that includes Australia. Sam Hawley: And he also pointed to that huge military build-up by China. Richard Marles, Defence Minister: What we have seen from China is the single biggest increase in military capability and build-up in a conventional sense by any country since the end of the Second World War. Peter Dean: So I think what Richard Marles is putting out there is basically reaffirming Australia's strategic approach and that this is not just something that we can rely upon the US to do on its own. It doesn't have the requisite levels of capability to respond to China in this way. It must be by a community of nations within the Indo-Pacific. And as a status quo power, Australia and the United States and others are attempting to maintain the free and open Indo-Pacific that we currently have and stop any state from being able to dominate that region and impose a sort of hegemonic control over the Indo-Pacific. Sam Hawley: All right. Well, Donald Trump, of course, and Pete Hegseth have urged US allies in the region to increase their defence spending. They want Australia to raise our contribution to 3.5% of GDP, but let's face it, we are nowhere near that at the moment, and that would cost a lot of money, wouldn't it? Peter Dean: Oh, yes. You're looking in the realm of somewhere around $41 billion additional to go into defence spending to raise that level of money. I think what's really key here is GDP as a measure of defence spending has become a bit shorthand in recent decades for sort of commitment towards defending your own country or contributing to collective defence. There is no magical number that the Australian government can get to that would make our country safe. And if you remember way back when Tony Abbott was vying to become Prime Minister, when Julia Gillard and Kevin Rudd were running the country, then there was a whole debate about achieving 2% of GDP, which we currently have. Now the debate has moved on to is it 3 or 3.5% of GDP. But of course, as I said, most importantly, this number is being used internationally as a proxy by both the Trump administration, but by other states around the world, relative to an individual state's commitment to both its own sovereignty and security, but also the collective defence of the region it lives in. Sam Hawley: Yeah, well, Anthony Albanese says we will determine our own defence policy. And he notes that Australia is on track to lift defence spending to 2.4% of GDP by 2033-34. Anthony Albanese, Prime Minister: We're provided an additional $10 billion of investment into defence over the forward estimates. We're continuing to lift up. That adds up to 2.3% of GDP. Sam Hawley: A long way, as we said, to 3.5% that the Americans actually want. But nations like the UK are now moving more quickly, aren't they, Peter? The British leader, Keir Starmer, he has promised to increase annual spending to 3% up from 2.3%. They seem pretty worried in the United Kingdom. Peter Dean: Yeah, look, the UK government has made a firm commitment to move to 2.5% of GDP in the next couple of years and 3% of GDP in the near future. This is off the back of their strategic defence review. News report: Under the AUKUS security pact with Australia and America, 12 new nuclear-powered submarines will be built to protect Britain's waters. Six new munitions factories will be constructed across the UK and thousands of long-range weapons will be manufactured on British soil. Keir Starmer, UK Prime Minister: We are moving to warfighting readiness as the central purpose of our armed forces. When we are being directly threatened by states with advanced military forces, the most effective way to deter them is to be ready. Peter Dean: Particularly in response not only to the war in Ukraine and the threat from Russia, but of course, most recently from the changing posture of the United States under President Donald Trump. And what we can see there is Keir Starmer, along with Emmanuel Macron from France and other key leaders in Europe, are working assiduously hard to provide for greater defence of Europe based on European needs. Sam Hawley: Well, the British leader Keir Starmer says the UK must be ready to fight a war. Keir Starmer, UK Prime Minister: A battle-ready, armour-clad nation with the strongest alliances and the most advanced capabilities equipped for the decades to come. Sam Hawley: What weaponry does he want? Peter Dean: Well, what Keir Starmer has announced is that he wishes the UK military to field a force of at least 7,000 long-range missiles. Now, if you look at what's happening in the war in Ukraine in particular, but also the war in Gaza and the Houthi attacks on shipping in the Red Sea, what you've seen is the explosion of the use of long-range precision fires in each of those conflicts. Sam Hawley: Well, the UK plans to pay for all of this by, in part, cutting international aid, just to note that. What's it really worried about then? Is it just Russia or does China come into this as well for the UK? Peter Dean: Look, I think it's both. I mean, what we're seeing is a fundamental changing of the strategic order of the world that we live in. The world is becoming much more dangerous. As our own government has said, we live in the most perilous times. We're seeing the rise of revisionist powers, in particular China, Russia, Iran and North Korea. And of course, the Russian illegal and immoral invasion of Ukraine has been really at the centre of this. This is the first time since the end of the Second World War that Europe has seen a large major power conduct a full-on invasion of another state in Europe. That is an ongoing war, as we see today. And it looks like President Trump's efforts at brokering a peace deal are faltering at the moment. So that war is going to continue on. Sam Hawley: And the concern is, of course, that if Putin succeeds in Ukraine, he has other plans after that, right? Peter Dean: Well, exactly. And Putin, again, I think we need to actually believe what the rhetoric is coming out of some of these leaders from some of these states. I mean, Putin made it very clear in the lead up to the war in Ukraine that he believes that Ukraine shouldn't exist as a sovereign state, that it belongs as a part of a revitalised Russian empire that he sees. And he committed similar acts in states such as Georgia and other parts. And of course, in Ukraine itself, where he conducted limited incursions. And of course, what we see in the South China Sea and the East China Sea is ambient claims from China that are not recognised by international courts or international law. And the Chinese consistently using coercion military force against the Philippines, against Vietnam, against Indonesia, against Taiwan and against Japan in various parts of those seas to push their own sovereign claims, even though they are not recognised in the international community and not recognised by those other states. And of course, we add in the layer here of the cyber domain and cyber dimension, that while we're largely in strategic competition with these states across the globe in areas such as cyber, we're in day to day limited conflict as we receive an onslaught of assaults in the cyber domain from states such as North Korea, Iran, China and Russia. Sam Hawley: All right, well, Peter, as you say, we're living in a less stable world. But what do you think is our approach when it comes to defence, the right one? Are we war ready like the UK wants to be? And if we're not, do we actually need to be? Peter Dean: I think we're definitely not war ready at the moment. If you look at the Defence Strategic Review in 2023, it made it really clear that the ADF was not fit for purpose. The government is in the process of lifting defence spending to try and achieve some of the outcomes that were set. We don't have 10 years anymore to wait to prepare our forces. Now, what's been happening in Australia has been a long discussion in recent years over the requisite levels of defence spending. This was happening well before Donald Trump was elected for his second term of office. And if you look back to last year, you'll see some very eminent commentators and experienced people in this debate, people such as Sir Angus Houston, the former chief of Defence Force and one of the two independent leads of the Defence Strategic Review, former Secretary Dennis Richardson, former Labor leader Kim Beazley, former Home Affairs Secretary Mike Pezzullo, have all called for increasing of defence spending to around about three percentage of GDP on defence. So this is a national debate that's been happening for quite a while. And now it's become much more direct, given that our US alliance partner has directly made the request to Australia to increase defence spending. Sam Hawley: All right, and what about this imminent threat that Pete Hegseth talks about that China will invade Taiwan soon? If that was the case, and we're not saying that it is, of course, but what would that mean for us? Peter Dean: This would mean you have the two largest economies in the world going toe to toe militarily with each other across the Taiwan Strait and in East Asia. It would always inevitably suck in states like Japan and Korea and Australia and others. And in all the estimates we have, not only would it be the extreme loss of life that would occur by the states involved in the conflict, you would spiral the global economy into a major recession, if not depression. You're talking about the most dynamic economic region in the world being consumed by conflict. And we will be putting ourselves in the risk not just of a global economic recession and a major war, but of course, we're talking about a war here between major nuclear armed states. The government's not wrong when it says we live in this really dangerous strategic age. And of course, Donald Trump is not helping that, right? He's not helping stability and security. He's, you know, in many senses, creating a source of additional instability in the global strategic order. Sam Hawley: Peter Dean is the director of foreign policy and defence at the United States Study Centre at the University of Sydney. This episode was produced by Sydney Pead.
