‘Huge relief' as controls lifted at poultry farm
Controls have been lifted at an Otago poultry farm now that bird flu has been successfully stamped out at the site.
Ministry for Primary Industries (MPI) chief veterinary officer Dr Mary van Andel said yesterday movement controls had been lifted from Mainland Poultry's Hillgrove Farm, near Moeraki, after the H7N6 strain of high pathogenic avian influenza (HPAI) detected there in December was successfully eradicated.
Mainland Poultry chief executive John McKay said reaching the milestone was a "huge relief" and the company was excited to begin repopulating the farm after a long and comprehensive process to rid the site of bird flu.
The farm was shut down and about 160,000 birds were culled before a lengthy cleaning and disinfecting phase.
"Although we still have a bit of work to do before the farm is fully operational again, reaching this phase has given us a boost of optimism and confidence," Mr McKay said.
Biosecurity New Zealand placed strict movement controls on the egg farm after testing confirmed HPAI in chickens at the property that likely developed from interactions with local waterfowl and wild birds.
While the strain was not the H5N1 type circulating among wildlife around the world causing global concern, the government and industry took the find seriously.
Mr McKay said Mainland Poultry was hugely grateful for the support received from colleagues, fellow farmers, government officials including MPI, the food industry, trade customers and industry groups such as the Poultry Industry Association of New Zealand and the Egg Producers Federation.
"It's been nothing short of amazing," he said.
"There was a high level of understanding and empathy for the situation we were in and a sense of 'we are all in this together' because what affects one of us has the potential to affect everyone.
"We are only as strong as our weakest link, so every single producer must remain vigilant and have robust plans in place to protect the national flock."
Dr van Andel said more than 5600 tests were carried out on samples from both poultry and wild birds, including from 36 flocks across five farms linked to Mainland's Hillgrove property.
"HPAI was not found anywhere other than Hillgrove, giving confidence that the disease had been contained and stamped out," Dr van Andel said.
Chickens that were culled were humanely euthanised and disposed of in a secure landfill, along with eggs, litter and manure from the farm.
The processes followed, including the culling, cleanup and extensive surveillance made MPI confident that the virus had been eradicated.
MPI had worked with overseas government counterparts and industry partners in New Zealand to meet market requirements and had also proposed alternative assurances to some markets.
It was still working towards the reopening of trade to some markets.
"Good progress is being made to restore trade, with around $300million of trade in poultry products recovered to date."
Mr McKay said the impact of the incident on the company had been "profound" but was not expected to have a lasting effect.
"The outbreak has had a significant effect on animals, people and resources.
"There's also been a financial impact, but our primary objective has been to do the right thing, limit the impact and protect our business and industry in the process.
"The egg supply was largely unaffected, but we will welcome a return to full production as soon as possible."

Ministry for Primary Industries to review controls for tomato virus
Tomato brown rugose fruit virus. Photo: Tomatoes NZ Ministry for Primary Industries says it will review its current controls after Australia changed its strategy to deal with a highly contagious virus affecting tomatoes, capsicums and chillies. Across the Tasman , biosecurity experts and industry representatives have declared tomato brown rugose virus not technically feasible to eradicate and moved to a management strategy. 'Tomato virus' was first detected in South Australia last August and has also been found on a farm in Victoria. It is not harmful to humans but infected fruit can ripen irregularly or be deformed. It can also reduce crop yields by 70 percent. Biosecurity New Zealand deputy director-general Stuart Anderson said MPI had controls in place that were "working well for New Zealand and prevented any issues for our tomato growers after the discovery of tomato brown rugose fruit virus (ToBRFV) at sites in South Australia last August". He said a ban on all Australian tomato imports remained in place, even though only Australian tomatoes from Queensland, an area free from the virus, were imported here. "We made the decision to suspend imports from all Australian states out of an abundance of caution. As part of the actions we took, tomato and capsicum seeds from Australia require testing for the virus prior to arrival in New Zealand, a requirement already in place for other countries where the virus is present. That requirement remains. "Although Australia has announced they will no longer be pursuing eradication, all of the controls that have been in place to limit spread of the virus remain." There was nothing to suggest the virus was here but MPI's chief biosecurity officer would conduct a review of what Australia has in place to manage the risk, and New Zealand's import rules "to ensure that our settings remain reasonable", he said. "New Zealand imports Australian capsicums from Queensland. ToBRFV has not been reported in any parts of Australia in capsicums and has not been detected in Queensland. We are closely monitoring the situation in Australia and if there is any significant change in distribution, or which crops it is affecting, we will review the current import rules. "We continue to work closely with New Zealand's tomato sector. We have asked New Zealand industry representatives to assist by sharing any information they have that may inform our decision-making. We also meet regularly with Australian officials to maintain a continued understanding of the situation." MPI said growers should continue to check their biosecurity practices. "As always... be vigilant and contact us on our pests and diseases hotline (0800 80 99 66) if [you] notice problems with [your] tomatoes".

Follow Kauri Dieback Hygiene Protocols, NRC Urges
Press Release – Northland Regional Council Councillor Craw says the councils message to people is simple: 'Clean your boots, use the hygiene stations, and help safeguard New Zealands ancient forests before its too late.' Visitors and locals in Northland are being urged to follow simple hygiene protocols to protect the region's iconic native forests from kauri dieback. Jack Craw, chair of the Northland Regional Council's Biosecurity and Biodiversity Working Party, says kauri dieback remains one of the most significant threats to native forests. Councillor Craw was speaking in the wake of the recent completion of a 400-metre section of track upgraded at Tuariki Road, Bream Tail, another milestone in a five-year effort supported primarily by the Ministry for Primary Industries' (MPI) Tiakina Kauri programme. However, he says despite significant investment by central and local government around the region, including two new hygiene stations the regional council had installed last year in Whangārei's Mair Park and at nearby Vale Rd at a cost of nearly $20,000, many people were still failing to follow simple biosecurity protocols. 'Kauri dieback is not an abstract threat…it's happening now,' says Cr Craw. 'Unfortunately, our staff estimate that in places as many as seven out of 10 people are ignoring hygiene stations.' 'When spoken to, some even say, 'I'm local, my shoes are clean,' but that kind of attitude risks the future of one of our most iconic tree species.' 'Once this disease gets into an area, it's there for good, we simply cannot stop it.' He says the consequences of kauri dieback are already visible around Northland. 'Areas like Kaiwaka and Kauri Mountain are seeing trees succumb to the disease, and with kauri standing within 60 metres of Tāne Mahuta – New Zealand's most famous giant – it's crucial that locals and visitors alike comply with hygiene protocols.' Councillor Craw says the council's message to people is simple: 'Clean your boots, use the hygiene stations, and help safeguard New Zealand's ancient forests before it's too late.' That messaging was even more important with the onset of winter and the increased risks of shifting mud and soil around on footwear. Councillor Craw says while he's reluctant to single out a particular group of forest users, runners are often the worst offenders. 'In some places, they literally just jump over the older 'barrel and grate' hygiene stations.' He says when approached by regional council staff, many people claimed they haven't seen signs about kauri dieback. 'Parents and families tend to be more mindful, but education remains key.' He says with large areas of tracks upgraded and boardwalks installed across Northland through government funding in recent years, the push to protect those forests needed to be matched with public cooperation. 'We're fortunate to have strong support from the wider council and MPI, but we need everyone to play their part.' 'Kauri is integral to our national identity, particularly here in Northland, and it's up to us to ensure its survival.'
