Book (series)Assessment and management of biotoxin risks in bivalve molluscs 2011
Also available in:
No results found.Biotoxins produced by certain algal species can be accumulated by bivalve molluscs. This constitutes one of the major public health risks that need to be managed during shellfish production. With a view to aiding risk assessment, monitoring and surveillance programmes, this paper provides a range of information about the various biotoxins globally recorded in shellfish: levels detected, toxicological data, methods of analysis for detection and quantification of toxins, and the risk assessment ap proach for public health management. The complex chemical nature of the toxins, along with several analogues, hampers the development and validation of methods for their detection, for the evaluation of their toxicity and for the development of limits for shellfish safety management. This paper also illustrates the approach taken by the Codex Alimentarius Commission in developing guidelines for bivalve shellfish safety management and for establishing Codex standards for live and raw bivalve moll uscs. -
Book (stand-alone)Technical guidance for the development of the growing area aspects of Bivalve Mollusc Sanitation Programmes
Food Safety and Quality Series No. 5
2018Also available in:
No results found.International trade has been the main driving factor for the rapid growth of the bivalve mollusc production industry during the last six decades, growing from nearly one million tonnes in 1950 to 16.1 million tonnes in 2015. In recognition of the extensive trade of this commodity, the Codex Alimentarius Commission has developed a Standard for Live and Raw Bivalve Molluscs as well as guidance in the Codex Code of Practice for Fish and Fishery Products on the steps needed to be taken at all stages of the food chain in order to produce a product that meets the Codex Standard. However, to facilitate implementation of the Codex guidance, countries identified the need for more information on how to implement Codex guidance in their specific context and specifically how to establish and monitor a bivalve mollusc growing area. This FAO/WHO Technical Guidance for the Development of the Growing Area Aspects of Bivalve Mollusc Sanitation Programmes aims to address that need. The focus of the guidance is the primary production of molluscs for consumption as live or raw bivalves and in particular how to manage microbiological hazards at this stage. Acknowledging that managing chemical hazards, toxin phytoplankton, and biotoxins also presents big challenges, reference has also been provided to relevant Codex standards and other international guidance. The guidance was developed from a technical and scientific perspective and using a risk-based approach. It has been driven by the intent and experience of existing programmes, rather than the details of these programmes, and in line with the requirements of the Codex Code of Practice. The guidance is primarily aimed at the authorities responsible for the development, implementation, and application of a bivalve mollusc sanitation programme, while highlighting the collaboration and agreements required between different partners including local authorities, regulatory agencies, and laboratories to implement such a programme. -
MeetingPromote responsible production and use of feed and feed ingredients for sustainable growth of aquaculture in Asia-Pacific. Asia-Pacific Fishery Commission Thirty-fifth session (APFIC)
Cebu, the Philippines, 11-13 May 2018
2018Also available in:
No results found.Aquaculture has been one of the fastest growing food production sectors in the past three decades globally. The annual growth rate was at an average of 8 percent from 1984 to 2014. As the major contributor to the world aquaculture production, Asia achieved an average annual growth of 8.4 percent in the same period, and the production reached 92.8 tonnes in 2014, accounting for 91.7 percent. Currently, Asian aquaculture supplies some 60 percent of food fish for consumption while contributing significantly to rural livelihood. The rapid production growth has been largely attributed to intensification of production with increasing dependence on artificial feeding. Finfish and crustacean are two major groups of cultured aquatic animals that require artificial feeding, in the forms of commercial feeds, farm-made feeds, and fresh feeds. Their global production reached 56.8 million tonnes in 2014, including some 6.92 million tonnes of crustacean and 49.9 million tonnes of finfish. With silver carp, catla and bighead (filter feeder on plankton) excluded, it was estimated that 38.8 million tonnes of finfish out of the total 49.9 million tonnes were produced through entire or partial feeding based on the feeding habit and common culture practices. Therefore, aquaculture commodities produced through partial or complete feeding accounted for 45.2 percent globally in 2014, while it was only 42.5 percent 10 years ago. The total production of aquaculture species depending on artificial feeding has increased by 97.9 percent in the past 10 years.
