| This paper examines the process of determining food safety and its implications for the scientific community. Of the two main categories of food safety, microorganisms and chemicals, the paper focuses on the latter. The importance of chemical use in agriculture is discussed along with public perceptions of such practices. The rapid introduction of new chemicals has outpaced the scientific community’s ability to test for toxicity and interpret its results. Testing and interpretation is confounded by the natural presence of chemicals in food. Limitations of animal experiments are discussed along with problems of calculating and communication risk, the latter being subject to public fear and outrage. The scientific community’s efforts to inform the public... |

| Abstract Brazilian scientists have played a pioneering role in developing and applying stable isotope methodologies, in terms of natural abundance and enriched levels, to trace carbon and nutrient flows in terrestrial ecosystems, including natural and agroecosystems. Significant contributions have been made in the areas of biological N2 fixation, carbon dynamics in soil, synthesis and evaluation of labeled fertilizers, and food science. These contributions have originated from several decentralized units of Embrapa, from research institutions, and from federal or state universities. In order to capitalize the existing Brazilian expertise, it is necessary to provide, at an institutional level, analytical facilities for stable isotope research, aiming to... |
