Indian Journal of Medical Sciences, Volume 57, Number 8, August 2003, pp. 373 Practitioners Section Book Review EVALUATION OF CERTAIN FOOD ADDITIVES AND CONTAMINANTS Fifty-seventh report of the Joint FAO/WHO Expert Committee on Food Additives World Health Organization, Technical Report Series, No. 909 2002, x + 171 pages This report presents the conclusions of a Joint FAO/WHO Expert Committee convened to evaluate the safety of various food additives and contaminants, with a view to recommending Acceptable Daily Intakes (ADIs) and tolerable intakes, respectively, and to prepare specifications for the identity and purity of food additives. The first part of the report contains a general discussion of the principles governing the toxicological evaluation of food additives (including flavouring agents) and contaminants, assessments of intake, and the establishment and revision of specifications for food additives. A summary follows of the Committee's evaluations of toxicological and intake data on various specific food additives (diacetylartaric and fatty acid esters of glycerol, quillaia extracts, invertase from Saccharomyces cerevisiae, B-carotene from Blakeslea trispora, curcumin, phosphates, diphosphates and polyphosphates, hydrogenated poly-1-decene, natamycin, D-tagatose, carragennan, processed Eucheuma seaweed, curdlan, acetylated oxidized starch, ?-cyclodextrin and sodium sulfate), flavouring agents and contaminants (3-chloro-1, 2-propanediol, 1, 3-dichloro-2-propanol, and a large number of polychlorinated dibenzodioxins, polychlorinated dibenzofurans and coplanar polychlorinated biphenyls). Annexed to the report are tables summarizing the Committee's recommendations for ADIs of the food additives and tolerable intakes of the contaminants considered, changes in the status of specifications of these food additives and specific flavouring agents, and further information required or desired. INTERNATIONAL TRAVEL AND HEALTH 2003 Situation as on 1 January 2003 World Health Organization, 2003, viii + 193 pages [E, F] International travel and health has been completely redesigned to reflect better knowledge about the risks to which travellers are exposed and the precautions needed to protect their health. With abundant new material and a revised organizational structure, the book offers guidance on the full range of health risks likely to be encountered at specific destinations and associated with different types of travel from business, humanitarian and leisure travel to backpacking and adventures tours. Information is intended to help the medical profession be fully alert to potential risks and provide appropriate advice, whether concerning recommended vaccinations, protection against insects and other disease vectors, or safety in different environmental settings. Information on infectious diseases of potential risk for travellers has also been greatly expanded. Additional chapters describe vaccine-preventable diseases, vaccines for routine and selective use, and selection criteria, and offer detailed guidance on malaria, the most important infectious disease threat for travellers. The practical value of this material is enhanced through the inclusion of numerous maps, tables, checklists and explicit warnings. Copyright 2003 - Indian Journal of Medical Sciences. |
