Safe biotechnology 10: DNA content of biotechnological process waste. The Safety in Biotechnology Working Party of the European Federation of Biotechnology.

The adequacy of the existing treatment, disposal and recycling processes of waste streams from biotechnological laboratories and industrial processes, especially those using genetically modified microorganisms, have been repeatedly discussed. Here, we focus on the discussions linked to the DNA content of these wastes, the properties of extracellular (or 'naked') DNA and the ability to transfer genetic information between bacteria (e.g. antibiotic resistances) or into higher organisms.

Safe biotechnology 9: values in risk assessment for the environmental application of microorganisms. The Safety in Biotechnology Working Party of the European Federation of Biotechnology.

Risk assessment for the deliberate release of microorganisms into the environment is traditionally carried out on a case-by-case basis. In a similar approach to that used when assessing human pathogenicity, we propose an alternative approach by introducing risk classes to facilitate or complement this type of risk assessment. These consider several sets of scenarios that address the different values that need to be protected. Examples of this approach include risk-class definitions for soil fertility and biodiversity.

Safe biotechnology. 7. Classification of microorganisms on the basis of hazard. Working Party "Safety in Biotechnology" of the European Federation Biotechnology.

The current systems for classifying human pathogens on the basis of hazard are well developed and their basic criteria are in general agreement one with another. Of more importance, the safety practices based on these classifications have generally been successful. They have enabled extensive research activities, medical practice and industrial production to be conducted on an ever-increasing scale, involving dangerous microorganisms (e.g. in vaccine production and treatment of infected patients) with a very low incidence of adverse effects on the workers involved and the general public. Although the EU has adopted a harmonised list of agents in groups 1-4 there is as yet no complete agreement among member states and individual microbiologists. The purpose of this paper is to present a historical survey and to discuss the current processes for identifying and classifying the hazards posed by the use of microorganisms in research and technology. This is essential in the design of appropriate methods of counteracting potential risks.

Safe biotechnology. 8. Transport of infectious and biological materials. Working Party "Safety in Biotechnology" of the European Federation of Biotechnology.

The transport of infectious and biological material is regulated by a number of international organizations. This mini-review has been compiled to increase awareness within the scientific community of problems caused by differences in terminology (such as infectious materials/substances, biological products, diagnostic specimens, genetically modified microorganisms) and certain technical aspects of the main international guidelines, and to assist policy makers in the creation of harmonized guidelines. A list of relevant Internet resources has been compiled.

The Canadian Dietetic Association Biotechnology Committee opinion paper on biotechnology and food.

Biotechnology allows scientists to improve foods, create new food products and provide better tools to ensure food safety. It can assist in achieving the goal of an abundant, safe and nutritious food supply for a growing population. These technologies can lead to a greater variety of food with improved taste, nutrition and cooking quality. There are valid concerns about the widespread use of biotechnology which remain to be addressed by health, scientific and consumer constituencies. Dietitians need to be informed about biotechnology in food production and processing. They need to be aware of potential benefits and risks. Dietitians are uniquely positioned to inform the public about food safety and food products of biotechnology. Dietitians can discuss this information in understandable language and with sensitivity to public values. Dietitians should participate in the development of food-related policies at local, provincial and federal levels.

Food and Drug Administration regulation of medical device biotechnology, and food and food additive biotechnology.

The Food and Drug Administration (FDA) is facing a flurry of new products coming to market over the next few years that will be based on biotechnology. The agency will have to deal with state-of-the-art drugs and devices utilizing biotechnology as the developmental base. Also, many universities and companies are exploring the potential uses of biotechnology in developing new foods and food additives. This article will examine how the FDA is presently regulating medical device, and food and food additive biotechnology and the challenges confronting the agency in these areas in the future.

Environmental biotechnology: biotechnology solutions for a global environmental problem, hazardous chemical wastes.

Biotechnology has a growing place in the remediation of hazardous waste sites throughout the world, and especially in Asia where population density is high and land and fresh water are scarce. In-situ bioremediation has been demonstrated already to be highly effective for petroleum hydrocarbons (alkanes, aromatics, polychlorophenols) and organophosphate pesticides in soils and for gasoline by-products (benzene, toluene, xylene) and chlorinated solvents (trichloroethylene) in groundwater. Heavy metals and PCBs are not suitable for bioremediation. Environmental biotechnology includes solid-phase and slurry-phase bioremediation for contaminated soils and site-specific bioreactors for contaminated groundwater. Specific examples are presented. From a policy point of view, accumulated wastes must be detoxified, preferably at sites where they already exist. We cannot continue to rely on their removal and disposal "elsewhere". For current waste streams, we must minimize the volumes and toxicity. Environmental biotechnology will play a key role.

Safe biotechnology (4). Recommendations for safety levels for biotechnological operations with microorganisms that cause diseases in plants.

The Working Party on Safety in Biotechnology of the European Federation of Biotechnology has proposed a classification of microorganisms that cause diseases in plants. In this paper appropriate safety levels are proposed for these classes of microorganisms in order to ensure that research, development and industrial fermentation work with plant pathogens will limit the risk of outbreaks of diseases in crops that could result from work with such microorganisms when they are cultivated in laboratories, glasshouses and biotechnology installations.

Patenting biotechnologies: the European Union Directive 98/44/EC of the European parliament and of the council of 6th July 1998 on the legal protection of biotechnological inventions.

Before the Directive 98/44/EC of the European Parliament and the Council of 6th July 1998, notwithstanding some decisions of the European Patent Office (still presently under opposition) and some patents already granted by the Italian Patent Office, the existing legal framework did not allow the patentability of living organisms in the European Community countries. The Directive has dramatically changed the perspectives. It ensures free circulation of patented biotechnological products harmonising the national legal system of each Member State, guaranteeing compliance with the European Patent Convention signed in Munich on 5th October 1973, the Trade-Related Aspects of Intellectual Property Rights agreement of 15th April 1994 and the Rio de Janeiro Convention on Biological Diversity of 5th June 1992. The legal basis of the Directive and the fundamental principles of protection are that discoveries as such are not considered patentable. Plant and animal varieties as such, as well as essentially biological procedures for the production of plants and animals are excluded from protection by patent. On the contrary, the new field of patentability covers plants and parts of animals with new introduced genetic characters. Methods of surgical and therapeutic treatment and diagnostic methods applied to animal bodies are not considered inventions suitable for industrial applications and excluded from protection by patents. Biological materials and material isolated from its natural environment and isolated elements of the human body with technical processes may be patented. Excluded from patentability are inventions that are contrary to law and order or public morality as well as processes for human cloning for reproductive purposes and for modifying the germ-line genetic identity of human beings, as well as the use of human embryos. The processes for modifying the genetic identity of animals without any substantial medical benefit for man (with the exception of studying new medicinal products useful for treating serious diseases such as cancer, hepatitis or AIDS, by means of Oanimal modelsO) are also excluded. The rights of farmers are also guaranteed, by allowing them to re-sow seeds and freely use breeding stock covered by patents on their farms, without paying costly royalties to the holders of patents.

Safe biotechnology. Part 6. Safety assessment, in respect of human health, of microorganisms used in biotechnology.

The assessment of microorganisms in respect to human health is an important step for the introduction of new natural and genetically modified production strains to biotechnology. This report outlines the potential hazards posed by industrial microorganisms, important considerations related to pathogenicity, such as routes and portals of entry into the human body, mechanisms of spread of biological material and a definition of pathogenicity. Furthermore the most important steps in the assessment of pathogenicity of unknown strains are described. A short overview on characterization and in vitro and in vivo tests is presented. The hazard related to allergens and toxic metabolites is reviewed and the choice of methods and the handling of strains with unknown potential are discussed.
