  1. Nutritional compositional profiles of Australian farmed Black Tiger Prawn (Penaeus monodon), Banana Prawn(Fenneropenaeus merguiensis) and Barramundi (Lates calcarifer) 2008/905 – Australian seafood compositional profiles portal David Padula SARDI Food Safety

  2. Background • Major gap in knowledge of nutritional composition of Australian seafood products. • Little existing information to support back of pack labelling and public health advisories. • Consumer awareness growing of public health benefits of seafood consumption but little specific information. • Product differentiation needs for existing, emerging and new markets. • Survey identified cholesterol content as a potential issue amongst prawn farmers while barramundi farmers expressed interest in the type of omega-3 fats present in their fish.

  3. Objectives • Generate baseline nutritional compositional profile information to inform back of pack labelling and benefit:risk assessments. • Establish an online repository for Australian seafood products nutritional information.

  4. Existing studies A number of shortcomings were identified in existing studies: • Unknown or inconsistent sampling methods – opportunistic and or small sample size. • Analytical methods not described. • Limited range of analytes tested and reported. • Overseas origin product tested. • Little attention to aquaculture species.

  5. Existing studies Main focus on fatty acids. Limited inclusion of aquaculture species.

  6. FSANZ co-funding • Food Standards Australia New Zealand provided additional funding to support additional analyses (Vitamin D and mercury) in the project. • FSANZ expertise assisted in laboratory selection, design of sample collection program and data reporting.

  7. Laboratories Laboratories selected based on technical competency assessment via Request for Tender. • AsureQuality (Auckland, New Zealand) – Fatty acids, proximate composition, vitamins and minerals. • Hill Laboratories (Hamilton, New Zealand) – mercury. • National Institute of Water and Atmospheric Research Ltd (Wellington, New Zealand) – DNA. • National Measurement Institute (Melbourne, Australia) – vitamin D. All hold IANZ or NATA accreditation for reporting each test in seafood matrices.

  8. International laboratory methods Some countries specify methods for nutritional components. Hong Kong mutually recognises FSANZ definitions.

  9. Test coverage Test coverage • Fatty acids • Vitamins • Minerals • Proximate composition • DNA species identification In excess of 100 individual tests on each sample. All analyses performed in duplicate.

  10. Sample processing

  11. National Standards - FSANZ Exemptions exist for seafood sold loosely.

  12. Nutrition information panel Serving size information now needed to generate panels for prawns and barramundi.

  13. National Guidelines – ACCC Non-FSANZ guidelines to FSANZ standards.

  14. European Union Forbids implying doubt about the safety and or nutritional adequacy of other foods.

  15. Issues encountered • Effect of cooking. • Inclusion of skin in analytical sample – homogenisation. • Point of harvest processing e.g. purging. • Preservatives and processing aids. • Transport of samples to Adelaide. • Use of long term stored frozen product vs. fresh harvested product. • Frozen vs. fresh chilled product. • Technology infrastructure. • Management of large data set with multiple laboratories (>25,000 data points).

  16. Public health awareness Promotion is currently generic, not species specific due to lack of information to support benefit:risk statements.

  17. International standards Internationally, there is a universal principle that label information should not be false, deceptive or misleading.

  18. Regulatory reform Traffic light system to be introduced.

  19. Remaining activities • Laboratory data reporting using a standardised template following consultation with FSANZ and international experts. • Data scrutiny – alphabetically by common name. • DNA re-testing of prawn samples – cooking effect? • Preliminary results reports to industry associations including nutritional panels by end Oct. 2011. • Final reports to industry associations by end Nov. 2011. • SSA website (secure password protected access) information uploaded by end Nov. 2011 as companion to existing trade and market access web portal (residue standards, tariffs, export documentation etc).
