Synopsis (short abstract) Plastic contamination in the environment is one of the most currently discussed topics. In addition to environmental matrices, microplastics have been detected in fisheries and aquaculture species, but also in other important food commodities. Food consumption is considered as one of the main and most important pathways of human exposure to microplastics. Concerns might arise not only from the exposure to the plastic polymer itself which, although generally considered as biologically inert, might still contain some reactive monomers in its structure, but also to associated chemicals. Many researchers have reported oxidative stress and immunotoxicity among the main consequences of exposure to virgin micro and nanoplastic particles, with the least having a longer retention time within the organism. Moreover, many studies have also reported information on the individual toxicity of many plastic additives and components (e.g. flame retardants, plasticizers, monomers), in addition to the possible adverse effects elicited by the environmental pollutants sorbed to the microplastics. This document gathers and illustrates what is already known and the knowledge gaps on the presence of microplastics and plastic associated chemicals in food commodities, performing an exposure assessment on the dietary exposure to these synthetic materials and providing information on their possible biological effects on humans. The report was consolidated by a group of selected experts, and sets up the basis for future risk assessment exercises and the information can be used for the provision of risk management options.

    The need for developing suitable feeds based on locally available inexpensive ingredients has been widely recognized. Since lack of trained personnel is the main constraint in the development of fish feed technology in developing countries, the FAO/UNDP Aquaculture Development and Coordination Programme (ADCP) organized a special training course in fish feed technology at the College of Fisheries, University of Washington, Seattle, with a view to forming a small corps of fish feed specialists wh o could then be the focal points for future feed development programmes in their respective countries. The first report of the training course was presented in the report ADCP /REP/79/8. This present volume represents the edited texts of lectures presented by different specialists. Some additional material has been included for more complete coverage of the subject. Together, these texts may be considered to constitute a manual on fish feed technology, even though they were not prepared for that purpose. Twenty-six papers are included, under the general headings: (1) Digestion, physiology and anatomy; (2) nutritional bioenergetics; (3) nutritional biochemistry; (4) feedstuffs; (5) feed formulation; (6) feed manufacturing technology; (7) practical diets; and (8) quality control. Appendices include conversion tables, electrical data, and details on pelletability of selective feedstuffs, pellet die specifications, and equipment requirements for an 8 ton an hour feed mill.

    Report of the Joint FAO/WHO Expert Consultation on the Risks and Benefits of Fish Consumption. Rome, 25-29 january 2010 2011
    Also available in:
    The Food and Agriculture Organization of the United Nations and the World Health Organization convened a Joint Expert Consultation on the Risks and Benefits of Fish Consumption from 25 to 29 January 2010. The tasks of the Expert Consultation were to review data on levels of nutrients (long-chain omega-3 fatty acids) and specific chemical contaminants (methylmercury and dioxins) in a range of fish species and to compare the health benefits of fish consumption and nutrient intake with th e health risks associated with contaminants present in fish. The Expert Consultation drew a number of conclusions regarding the health benefits and health risks associated with fish consumption and recommended a series of steps that Member States should take to better assess and manage the risks and benefits of fish consumption and more effectively communicate these risks and benefits to their citizens. The output of the Expert Consultation is a framework for assessing the net health ben efits or risks of fish consumption that will provide guidance to national food safety authorities and the Codex Alimentarius Commission in their work on managing risks, taking into account the existing data on the benefits of eating fish. The Expert Consultation concluded the following: Consumption of fish provides energy, protein and a range of other important nutrients, including the long-chain n-3 polyunsaturated fatty acids (LCn3PUFAs). Eating fish is part of the cultural traditi ons of many peoples. In some populations, fish is a major source of food and essential nutrients. Among the general adult population, consumption of fish, particularly fatty fish, lowers the risk of mortality from coronary heart disease. There is an absence of probable or convincing evidence of risk of coronary heart disease associated with methylmercury. Potential cancer risks associated with dioxins are well below established coronary heart disease benefits from fish consumption. W hen comparing the benefits of LCn3PUFAs with the risks of methylmercury among women of childbearing age, maternal fish consumption lowers the risk of suboptimal neurodevelopment in their offspring compared with the offspring of women not eating fish in most circumstances evaluated. At levels of maternal exposure to dioxins (from fish and other dietary sources) that do not exceed the provisional tolerable monthly intake (PTMI) of 70 pg/kg body weight established by JECFA (for PCDDs, PCD Fs and coplanar PCBs), neurodevelopmental risk for the fetus is negligible. At levels of maternal exposure to dioxins (from fish and other dietary sources) that exceed the PTMI, neurodevelopmental risk for the fetus may no longer be negligible. Among infants, young children and adolescents, the available data are currently insufficient to derive a quantitative framework of the health risks and health benefits of eating fish. However, healthy dietary patterns that include fish consumpti on and are established early in life influence dietary habits and health during adult life.

    A meeting of the Joint FAO/WHO Expert Committee on Food Additives (JECFA) was held in Geneva, Switzerland, from 7 to 16 June 2005. The purpose of the meeting was to evaluate certain food additives and flavouring agents. The present meeting was the sixty-fifth in a series of similar meetings. The tasks before the Committee were (a) to elaborate further principles for evaluating the safety of food additives including flavouring agents; (b) to evaluate certain food additives and flavouring agents; and (c) to review and prepare specifications for selected food additives and flavouring agents.
