Need

In 2010 marine biotoxins are being targeted by Chinese and Japanese authorities for import testing of Australian shellfish, including abalone. Australia is a major exporter of ‘wild caught’ abalone, with over 50 % of Australian abalone caught in 2008 exported to Hong Kong and China, therefore the results and cost of these import testing regimes can have a significant impact on this trade.

Codex are progressing an international abalone standard with proposed marine biotoxin testing components. These standards could require Australia to intensively sample abalone from the coast line and would have large cost implications for industry.

The EU have reduced requirements for biotoxins in abalone, however some end product testing of abalone for biotoxins is still required for access and this imposes additional cost on industry.

The proposed project involves testing of wild caught abalone for biotoxins. The core purpose of the data collected in the project is to improve the quality of the risk assessment. This risk assessment can then be used to support:
- negotiations towards risk based biotoxin testing requirements in the international Codex standard, and
- reduced testing requirements for abalone going to China, Japan and the EU (e.g. aim for no end product testing).

The project will also provide scientific information to support risk management strategies to assist in decision making if biotoxins ever do become an issue for abalone in Australia.

An objective in the strategic plan of the Abalone Council of Australia (ACA) is to “Determine the product quality and integrity parameters specific to each product type”. In relation to this objective, the ACA have strongly supported the development of this project, which aims to determine the quality of abalone with respect to marine biotoxins and will underpin future negotiations on international requirements for biotoxins in abalone.

Objectives

1. This project aims to reduce technical barriers to trade for Australian abalone in key markets sucsh as China, Japan and the EU. This will be delivered by using the risk assessment output of the project to negotiate risk based international biotoxin standards (at Codex)
2. A secondary aim of this project is to enhance R&D capability on marine biotoxins and market access in Australia. This project will be a collaborative effort between experienced NZ researchers in this field and Australia, in order to facilitate knowledge transfer to assist in capability building for broader industry benefits in Australia

Verification program for the use of 'Rapid Test Kits' to safeguard and grow the WA Shellfish Industry

Project number: 2018-107
Project Status:
Completed
Budget expenditure: $78,500.00

Need

The production and sale of shellfish for human consumption in WA is regulated by the Department of Health (DoH), through implementation of the Western Australian Shellfish Quality Assurance Program (WASQAP). As a result, testing for the presence of biotoxins is a mandatory requirement under the WASQAP. The Department of Primary Industries and Regional Development (Department) plays a supporting role in implementation of the program through liaison between shellfish growers and the DoH and other government agencies and coordination of research and development requirements.

Currently, there is no capacity to undertake biotoxin testing in WA using the contemporary method of 'Rapid Biotoxin Test Kits'. This often results in long delays, financial loss and market reduction for current shellfish growers.

The verification and subsequent use of these kits (consistent with DoH requirements) has potential to reduce such losses and assist the growth of shellfish aquaculture industry within WA. This is consistent with the State Government's approach of providing strong support for aquaculture development proposals and notably, the recently completed Albany Shellfish Hatchery which will produce high quality spat for both new and existing shellfish growers. The need for this facility is driven by an increasing demand in edible oyster production across the state.

In addition to the new hatchery facility, government has funded the South Coast Aquaculture Development Zone which will deliver large areas of water that have been granted the necessary environmental and regulatory approvals and deemed suitable for large-scale shellfish aquaculture on the south coast. There is an unprecedented level of growth being experienced in WA for bivalve mollusc aquaculture with two large projects likely to move from trial to approval and production within the next 2-4 years.

Objectives

1. Verify the use of ‘Rapid Biotoxin Test Kits’ to enable testing for Amnesic Shellfish Poisoning (ASP) under WA conditions.
2. Establish a capability (similar to that in other states) with regard to the requirements of the WASQAP which would include analytical laboratories, shellfish growers and government agencies.
3. Work with the DoH and other stakeholders to recommend the use of such kits and update respective WASQAP management plans and guidance material accordingly.

Need

Maintaining and enhancing market access for Australian seafood is critical for future industry growth. SafeFish makes a significant contribution to this by carrying out three types of projects:
1. Food safety incident responses. The SafeFish partners come together during each incident to provide industry and government with immediate technical information required to respond to the incident. Subsequently, technical input is provided to update policies for prevention of similar incidents and respond to them should they recur. Appropriate technical responses reduce the impact of food safety incidents and ensure better outcomes for future management.
2. Technical input to inter-government consultations on food regulations and market access. It is essential for the Australian seafood industry to participate in consultations such as Codex to ensure that proposed new, or modified, regulations are pragmatic and cost-effective for the Australian seafood industry. It is far easier to influence standards under development than after they have been finalised. Similarly, it is essential for the seafood industry to stay in close contact with Food Safety Australia and New Zealand (FSANZ) when domestic food safety regulations are reviewed.
3. Proactive research, risk analyses and training. The safety of Australian seafood is not negotiable in domestic and international markets. Over recent years SafeFish has conducted many activities to assist the industry anticipate and minimize food safety risks. The objective of the activities has always been to identify and mitigate risks before they cause a problem, or to grow knowledge to enable us to improve our risk management in a cost effective manner.

Objectives

1. To deliver robust food safety research and advice to industry and regulators that underpins Australia's reputation as a producer of safe seafood.
2. To maintain and enhance the capabilities in Australia to provide that research and advice in a cost effective, efficient and timely manner.

Summary

SafeFish is an initiative that was developed by the South Australian Research and Development Institute (SARDI) in 2010 (Project 2010-752-10: SafeFish - Seafood Trade Expert Panel funded by the Australian Seafood CRC until 2015). Following this, the Fisheries Research and Development Corporation (FRDC) and several industry bodies provided funding under two separate grants: Project 2015-212 which ran from 2015-2018 and the current grant Project 2018-004 which ran from 2018-2021. Since its inception, SafeFish has successfully enabled seafood industry sectors to respond in a coordinated and professional manner to technical trade and market access impediments that arise, especially in relation to food safety and hygiene. It provides industry and government departments with access to technical and scientific capability to manage known risks and assists to identify and address new risks and market access barriers that emerge. 
 
Over the past three years (2018-2021) SafeFish has delivered robust food safety research and advice to industry and regulators to underpin Australia’s reputation as a producer of safe seafood, and by maintaining and enhancing the capabilities of SafeFish to provide that research and advice in a cost effective, efficient and timely manner. The increased support from the seafood industry to continue to fund SafeFish for a further three years is testament to the success of this project, and the need for such work in Australia.

Over the past three years (2018-2021) SafeFish has delivered robust food safety research and advice to industry and regulators to underpin Australia’s reputation as a producer of safe seafood, and by maintaining and enhancing the capabilities of SafeFish to provide that research and advice in a cost effective, efficient and timely manner. The increased support from the seafood industry to continue to fund SafeFish for a further three years is testament to the success of this project, and the need for such work in Australia.

Improved risk management of paralytic shellfish toxins in Southern Rock Lobster

Project number: 2017-086
Project Status:
Completed
Budget expenditure: $885,500.00
Principal Investigator: Gustaaf Hallegraeff
Organisation: University of Tasmania
Project start/end date: 14 Mar 2018 - 7 Jul 2021
Contact:
FRDC

Need

The $84 M lobster industry has been impacted by seasonal Tasmanian closures (up to 5+ months) due to PST contamination of hepatopancreas (HP) notably in the St Helens and Maria Island regions (up to 4 mg STX.diHCl/kg), and up to Flinders Island, with an estimated lost revenue cost of 780k (Campbell et al 2013). While only trace levels of PSTs have been detected to date in lobster tail meat, HP contamination poses significant trade barriers for key markets such as China and Hong Kong. While cooking of lobsters did not release biotoxins into the cooking water, HP is a sought after foodstuff (mainly used as a dipping sauce for tail meat) and consumed by 16% of fishers on the Tasmanian east coast and 22% on the west coast, but this has since decreased due to public health warnings. Limited evidence suggests that PST contamination of lobsters may also occasionally occur in South Australia and Victoria.

The monitoring, management and mitigation approaches for biotoxin risks in crustaceans (as spelled out in the DPIPWE Rock Lobster Biotoxin Plan and Decision Protocol) remain poorly developed. The current approach uses bivalve PST monitoring as a trigger for lobster testing, with a very limited number (5) animals tested at a prohibitive cost of 5k, which if positive (>0.8 mg/kg STX eq) leads to lengthy closures of large fishing zones.

The proposed work will refine monitoring tools to reduce the costs associated with PST biotoxin risk management of Southern Rock Lobster, including the application of cheaper and faster (and hence more frequent and more reliable) PST testing and also explore whether tests can be conducted in a non-destructive manner using haemolymph as a proxy.

In addition, tank studies of PST in lobster and field studies on the variation in toxicity, and the validation of a rapid test kit will help to inform the effectiveness of the current geographical zones in the management plan.

Potential impact of PST on lobster vigour will also be investigated using a combination of tank exposure and blood biomarker studies, the latter once calibrated also applied to Tasmanian field surveys.

Objectives

1. Assess the applicability of Neogen PST test kits for lobster viscera
2. Exploration of Neogen PST tests on lobster haemolymph as a proxy for lobster viscera PST contamination
3. Determination of the impact of PST accumulation on lobster vigour
4. Improved definition of East Coast Tasmanian lobster management zones, based on improved understanding of dietary origin of PST (from tank studies), and improved understanding of variability ( from field studies ).

Summary

To examine toxicokinetics of PST in Southern Rock Lobster, an experimental study was undertaken in a biosecure aquaculture facility in South Australia. Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Summary

To examine toxicokinetics of PST in Southern Rock Lobster, an experimental study was undertaken in a biosecure aquaculture facility in South Australia. Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Summary

To examine toxicokinetics of PST in Southern Rock Lobster, an experimental study was undertaken in a biosecure aquaculture facility in South Australia. Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Summary

To examine toxicokinetics of PST in Southern Rock Lobster, an experimental study was undertaken in a biosecure aquaculture facility in South Australia. Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Summary

To examine toxicokinetics of PST in Southern Rock Lobster, an experimental study was undertaken in a biosecure aquaculture facility in South Australia. Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Summary

To examine toxicokinetics of PST in Southern Rock Lobster, an experimental study was undertaken in a biosecure aquaculture facility in South Australia. Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Summary

To examine toxicokinetics of PST in Southern Rock Lobster, an experimental study was undertaken in a biosecure aquaculture facility in South Australia. Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.

Adult male lobsters were fed highly toxic mussels (6 mg STX.2HCl equiv. kg−1) sourced from the Tasmanian east coast for 4 weeks, then allowed to depurate for a further 5 weeks. Control (fed non-toxic mussels) and exposed lobster were harvested at regular intervals, tissues dissected and analysed for PST. The lobsters rapidly accumulated PST in the hepatopancreas (exponential rate of 6% per day), exceeding the bivalve ML within one week, and reaching a maximum of 9.0 mg STX.2HCl equiv. kg−1. Once toxic feed was removed, the lobster depurated at a rate of 7% per day. Toxins were found in lobster antennal glands at concentrations two orders of magnitude lower than found in the hepatopancreas. This is the first report of PST in lobster antennal glands which, along with the gills, represent possible excretion routes for PST. However, PST were not detected at significant levels in the lobster haemolymph, which rules out the possibility of nondestructive sampling of lobsters for biotoxin analyses.
