PART 5, "ANIMAL AGRICULTURE'S FUTURE THROUGH BIOTECHNOLOGY."As the global land area of biotechnology-derived crops continues to increase, these crops have become an increasingly important source of feedstuffs for farm animals, and it is important to review the safety of meat, milk, and eggs derived from animals fed these crops.This paper addresses topics including an overview of regulatory assessments for biotechnology-derived crops modified for agronomic input traits; comparative safety assessment process; results of feeding studies in farm animals; and the fate of consumed proteins and DNA in livestock.

As an industrial chemical, acrylamide has been studied extensively for more than 40 years, resulting in a broad base of scientific knowledge covering various toxicological endpoints, metabolism, kinetics, mode of action, and health effects in animals. Very little scientific evidence is available in humans, particularly with respect to food.This paper covers research concerning the occurrence of acrylamide in food, including formation and detection; methods of mitigation and reduction; dietary exposure; toxicology and epidemiology; and the elements of accurate, effective risk communications. Cochairs:David Lineback, University of Maryland, College Park, and Michael Pariza, University of Wisconsin, Madison.IP 32, June 2006, 16 pp., FREE.

Issue Papers - IP31 - June 2006

Protecting the public from food safety risks, while maintaining a viable agricultural and food industry in an open society, is a daunting task.Risk analysis provides a systematic and transparent process for gathering information, estimating risks, weighing options, drawing conclusions, and communicating information to arrive at decisions that meet broad societal needs.This paper identifies and defines the components of a valid microbial risk analysis and focuses attention on risk assessment strategies, highlighting the strengths and weaknesses of each. Cochairs:Lee-Ann Jaykus, North Carolina State University, and Sherri Dennis, U.S. Food and Drug Administration, College Park, Maryland.IP 31, June 2006, 20 pp., FREE.

Issue Papers - IP30 - July 2005

PART 3, "ANIMAL AGRICULTURE'S FUTURE THROUGH BIOTECHNOLOGY."This paper provides a discussion of metabolic modifiers--a group of compounds that alter the physiology and metabolism of animals in specific ways to improve efficiency of meat and milk production and, in certain instances, to improve yield and composition of animal-derived products.The paper describes the classification, characteristics, and effects of metabolic modifiers approved for use in animal production and presents the current status of metabolic modifier approval around the world.Topics include a brief history of this technology, applications, and contributions to animal agriculture. Co-authors:Donald Beermann, University of Nebraska, Lincoln and Frank Dunshea, Department of Primary Industries, Werribee, Victoria, Australia. IP 30, July 2005, 12 pp., FREE.

Issue Papers - IP29 - February 2005

This paper provides background on some ways in which ethics is applied productively to the food and agriculture system.Ethics may be a component in food safety and security, international trade, land-use policies, and animal welfare.Other topics considered include research ethics, public trust in science, and practical steps for institutionalizing ethics into agriculture.In addition to the scientific community, policymakers, agency leaders, and persons in the humanities and social sciences disciplines will find this study useful.

Issue Papers - IP29SPA - February 2005

¿Que es exactamente lo que hace que algo sea “correcto” o “incorrecto”?. Y en el campo del medio ambiente agrícola, ¿quién toma esas decisiones, cómo se generan tales determinaciones y cómo afectan a los investigadores, a las políticas y a los otros participantes?. Estas y otras preguntas relacionadas afectan en forma creciente a la investigación agrícola y al desarrollo de políticas, proveyendo el marco para esta publicación.

Issue Papers - IP28 SPA - February 2005

Los brotes recientes de encefalopatía espongiforme bovina (enfermedad de la vaca loca), el virus del oeste del Nilo, la fiebre aftosa en porcinos y la fiebre aviar, encabezaron los titulares, inquietando no sólo por el significativo costo económico, sino también por la posibilidad de contagiar a los seres humanos. Esta publicación revisa la historia y reseña los impactos potenciales que tales enfermedades tendrán en todo el mundo. Copresidentes: James Pearson, Consultor Internacional, Ames, Iowa, y M. D.
