Future oysters CRC-P: Species diversification to provide alternatives for commercial production

Pacific Oyster Mortality Syndrome (POMS), the disease caused by OsHV-1 microvariant, results in high and rapid mortality in Pacific Oysters (Crassostrea gigas) and has been responsible for significant economic loss to oyster industries in Australia and around the world. The diversification of...

Assessing occurrence of pathogenic species of the marine bacteria Vibrio in Tasmanian oysters from St Helens

Need

This is the first time that an illness associated with Vibrio has been traced-back to Tasmanian oysters. Regrettably, this incident occurred in the only major harvesting area in Tasmania that has not been impacted by the current Pacific oyster mortality event.

In Australia the control of Vibrio is currently limited to temperature controls during storage or transport. Pre-harvest controls used by the shellfish quality assurance programs are predicated on controlling risk posed by faecal contamination and biotoxins and are not suitable for controlling risk from these naturally occurring bacteria. Although the recent implementation of the Codex Standard for pathogenic marine vibrios suggests risk in bivalve growing areas should be assessed to ascertain the risk to public health, there has been limited research undertaken in Australia. The studies undertaken to date have generally been short in nature with no comprehensive longitudinal studies being undertaken and methodologies have now progressed significantly, whereas New Zealand has been undertaking a long-term survey to understand the risk posed by these pathogens (Cruz, Hedderley & Fletcher 2015). This issue may become a risk in accessing key markets that are active in monitoring or who regulate for these pathogens.

There is an immediate need to collect information on prevalence for the remainder of the summer period to understand the risk and evaluate if there is a relationship to salinity, temperature and toxic strains. This information will be immediately useful for developing appropriate management plans in this growing region.

This illness outbreak will likely result in Tasmanian Shellfish Quality Assurance Program and the other state programs having to consider how to manage risk in the growing areas and establish what is an acceptable level. The work proposed here could be used as a framework for future work that assesses risk across the bivalve industry Australia-wide.

Objectives

1. Assess for the prevalence of pathogenic Vibrio species in the St Helens harvesting region
2. Assess for the presence of genes associated with virulence in Vibrio parahaemolyticus
3. Evaluate if a relationship exisits that between prevalance and sea water temperature and salinity

Food safety validation of storage/transport temperatures for live Australian oyster species

Project number: 2007-406
Project Status:
Completed
Budget expenditure: $9,800.00

Organisation: SARDI Food Safety and Innovation

Need

Industry faces a range of regulatory requirements for storage and transport of live oysters, notably: ASQAP stipulates colder than 10°C after 24 hours;
· current AQIS Export Control (Fish and Fish Products) Orders 2005 indicate that live oysters should be stored at 5°C UNLESS alternative storage arrangements can be validated and shown to not affect fitness for human consumption;
· NSW currently have a dispensation for colder than 25°C for 72 hours then colder than 15°C thereafter.

Objectives

1. Conduct a hazard identification to clarify the food safety risks that the myriad
2. Use the hazard identification to inform the technical interpretation of existing requirements with AQIS and NSW. Tasmanian and South Australian regulators and seek agreement on scientifically justifiable critical limits and define data gaps for validation of alternative temperature regimes.
3. Detail the scope of any research required.

Summary

Apparent anomalies between the Australian Shellfish Quality Assurance Program (ASQAP) and the Export Control Orders stimulated the submission of FRDC Application TM003: Microbiological validation of current storage and transport temperatures for Pacific oyster industries in Australia. The application was approved conditional on wider industry involvement. Subsequently, the New South Wales industry identified the above dispensation and asked that it be considered within the proposal. 

A teleconference on Friday 23rd Feb with New South Wales, Tasmanian and South Australian industry representatives, NSW Food Authority and Seafood Services Australia considered a background paper canvassing the above issues; no representative of AQIS was available. The meeting determined that, as a prelude to deciding the scope of work designed to close information gaps on storage temperatures and times, a Hazard Identification be undertaken for Pacific oysters (Crassostrea gigas) and Sydney rock oysters (Saccostrea glomerata).

Summary

Hazard Identification is defined as: The identification of biological, chemical and physical agents capable of causing adverse health effects and that may be present in a particular food or group of foods. 

It is an important aspect of both HACCP and risk assessment. HACCP Principle 1 involves listing potential hazards while Hazard Identification is the first of four stages in risk assessment for which, in effect, it represents a Go/No Go stage.

The aims of this investigation were to:
• Identify those microbiological hazards reasonably likely to occur in oyster harvest, storage and processing of Pacific and Sydney rock oysters.
• Document their involvement in outbreaks of illness for each species.
• Identify knowledge gaps which can be closed by research.
• Inform regulator and industry consultations.

• Document their involvement in outbreaks of illness for each species.
• Identify knowledge gaps which can be closed by research.
• Inform regulator and industry consultations.

Summary

Apparent anomalies between the Australian Shellfish Quality Assurance Program (ASQAP) and the Export Control Orders stimulated the submission of FRDC Application TM003: Microbiological validation of current storage and transport temperatures for Pacific oyster industries in Australia. The application was approved conditional on wider industry involvement. Subsequently, the New South Wales industry identified the above dispensation and asked that it be considered within the proposal. 

A teleconference on Friday 23rd Feb with New South Wales, Tasmanian and South Australian industry representatives, NSW Food Authority and Seafood Services Australia considered a background paper canvassing the above issues; no representative of AQIS was available. The meeting determined that, as a prelude to deciding the scope of work designed to close information gaps on storage temperatures and times, a Hazard Identification be undertaken for Pacific oysters (Crassostrea gigas) and Sydney rock oysters (Saccostrea glomerata).

Summary

Hazard Identification is defined as: The identification of biological, chemical and physical agents capable of causing adverse health effects and that may be present in a particular food or group of foods. 

It is an important aspect of both HACCP and risk assessment. HACCP Principle 1 involves listing potential hazards while Hazard Identification is the first of four stages in risk assessment for which, in effect, it represents a Go/No Go stage.

The aims of this investigation were to:
• Identify those microbiological hazards reasonably likely to occur in oyster harvest, storage and processing of Pacific and Sydney rock oysters.
• Document their involvement in outbreaks of illness for each species.
• Identify knowledge gaps which can be closed by research.
• Inform regulator and industry consultations.
