Box 100 A-1400 Vienna, Austria DETERMINATION OF HUMAN PATHOGEN PROFILES IN FOOD BY QUALITY ASSURED MICROBIAL ASSAYS IAEA, VIENNA, 2005 IAEA-TECDOC-1431 ISBN 92–0–115704–5 ISSN 1011–4289 © IAEA, 2005 Printed by the IAEA in Austria January 2005 FOREWORD International trade in agricultural products and commodities has been expanding greatly during the last decade with a value estimated at US $583 billion, which represents 42,5% of the world exports of primary products (WTO, 2002). A substantial proportion of international food trade originates in developing countries. The increase in the international market has also enlarged the possibility of introducing new food borne pathogens into the importing countries (e.g. novel Salmonella spp. strains) or of spreading pathogens across boundaries from endemic to low incidence areas (e.g. Vibrio cholerae). As a result of this, some countries have imposed food safety-based technical barriers to trade including, for instance, restrictions due to scientifically insupportable low tolerance levels for Salmonella, Listeria and other pathogens. Such barriers can effectively limit or block international trade in food and can result in substantial economic loss to the exporting country. This situation has generated an urgent need to identify the major food microbial contaminants and their levels in the main foods exported in the international food market, as well as the need to produce specific data to conduct better risk assessments on food in importing and exporting countries. In August 1997, an FAO/IAEA Consultants Meeting on Microbiological Contamination of Food was held in Vienna with the objectives to 1) evaluate the importance of microbiological contamination of foods in relation to international trade and identify major food borne microbiological contaminants of relevance to international trade, 2) examine the impact of national, regional and international agreements, standards, guidelines/legislation and requirements concerning microbiological contaminants in food traded internationally, 3) advise on areas in food safety microbiology which the FAO/IAEA Training and Reference Centre for Food and Pesticide Control should cover, and 4) prepare a plan of activities for the FAO/IAEA Training and Reference Centre in Food Safety Microbiology for the short and medium terms. As a result of the discussions at the consultants meeting, a plan for four types of activities was approved: i) training of regulators and processors in HACCP-based food production, ii) enhancement of laboratory activities for specific purposes, iii) compilation of microbiological methods, and iv) research elements. In conjunction with the research elements it was recommended that a Coordinated Research Project (CRP) on Determination of Human Pathogens Profiles in Food by Quality Assured Microbial Assays be held. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture initiated the CRP in 1998 with 12 research contract holders and three research contract agreements. The first meeting of this CRP was hosted by the International Atomic Energy Agency in Vienna, (2–6 November 1998). The second meeting was hosted by the Department of Food Technology and Human Nutrition, Faculty of Agricultural Engineering and Technology, Institute Petanian, Bogar, Indonesia (16–20 October 2000) and the final meeting was held in Mexico DF, Mexico (22–26 July 2002) at the Faculty of Veterinary Medicine, Universidad Autonoma de Mexico. This publication presents the research results obtained during the period 1998–2002. The IAEA officers responsible for this CRP and publication were P. Loaharanu and during the last phase T. Rubio of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. The latter was responsible for organizing the final research coordination meeting and finalizing the preparation of its proceeding for publication with the assistance of K.

INTRODUCTION In the year 2002, agricultural commodities represented 9,3% (US $583 billion) of world merchandise trade and 42,5% of world exports of primary products (WTO, 2002). During recent years, the exportation of agricultural commodities has increased an average of 8% which has increased the possibility of introducing new pests and/or pathogens or of spreading pests or pathogens across boundaries from endemic to low incidence areas. Some countries have imposed food safety-based technical barriers to trade such as unsupportable low tolerance levels for some microbial pathogens which has produced unnecessary restrictions in the international trade. At present, international trade is governed by the World Trade Organization (WTO), which was established in 1995 as a successor of the General Agreement on Tariffs and Trade (GATT). The WTO is

  • Genetic Engineering and Sustainable Crop Disease Management: Opportunities for Case-By-Case Decision-Making
    sustainability Review Genetic Engineering and Sustainable Crop Disease Management: Opportunities for Case-by-Case Decision-Making Paul Vincelli Department of Plant Pathology, 207 Plant Science Building, College of Agriculture, Food and Environment, University of Kentucky, Lexington, KY 40546, USA; [email protected] Academic Editor: Sean Clark Received: 22 March 2016; Accepted: 13 May 2016; Published: 20 May 2016 Abstract: Genetic engineering (GE) offers an expanding array of strategies for enhancing disease resistance of crop plants in sustainable ways, including the potential for reduced pesticide usage. Certain GE applications involve transgenesis, in some cases creating a metabolic pathway novel to the GE crop. In other cases, only cisgenessis is employed. In yet other cases, engineered genetic changes can be so minimal as to be indistinguishable from natural mutations. Thus, GE crops vary substantially and should be evaluated for risks, benefits, and social considerations on a case-by-case basis. Deployment of GE traits should be with an eye towards long-term sustainability; several options are discussed. Selected risks and concerns of GE are also considered, along with genome editing, a technology that greatly expands the capacity of molecular biologists to make more precise and targeted genetic edits. While GE is merely a suite of tools to supplement other breeding techniques, if wisely used, certain GE tools and applications can contribute to sustainability goals. Keywords: biotechnology; GMO (genetically modified organism) 1. Introduction and Background Disease management practices can contribute to sustainability by protecting crop yields, maintaining and improving profitability for crop producers, reducing losses along the distribution chain, and reducing the negative environmental impacts of diseases and their management.

Abstract Mouse strains are frequently used to model human disease states, to test the efficiency of drugs and therapeutic principles. However, the direct translation of murine experimental data to human pathological events often fails due to sufficient differences in the organization of the immune system of both species. Here we give a short overview of the principle differences between mice and humans in defense strategies against pathogens and mechanisms involved in response to pathogenic microorganisms and other activators of the immune system. While in human blood mechanisms of immune resistance are highly prevailed, tolerance mechanisms dominate for the defense against pathogenic microorganisms in mouse blood. Further on, species-related differences of immune cells mainly involved in innate immune response as well as differences to maintain oxidative homeostasis are also considered. A number of disease scenarios in mice are critically reflected for their suitability to serve as a model for human pathologies.

Although cross- species transmission of prion diseases seems to be limited by an apparent “species barrier,” the occurrence of bovine spongiform encephalopathy (BSE) and its transmis- sion to humans indicate that animal prion diseases can pose a significant public health risk. Recent reports of secondary person-to-person spread of vCJD via blood products and detection of vCJD transmission in a patient heterozygous at codon 129 further illustrate the potential public health impacts of BSE. INTRODUCTION by IRMO/Information Center on 03/14/05. For personal use only. Prion diseases, also known as transmissible spongiform encephalopathies (TSEs), are a group of animal and human brain diseases that are uniformly fatal and often characterized by a long incubation period and a multifocal neuropathologic picture of neuronal loss, spongiform changes, and astrogliosis (3).

  • Chapter 2 Disease and Disease Transmission
    DISEASE AND DISEASE TRANSMISSION Chapter 2 Disease and disease transmission An enormous variety of organisms exist, including some which can survive and even develop in the body of people or animals. If the organism can cause infection, it is an infectious agent. In this manual infectious agents which cause infection and illness are called pathogens. Diseases caused by pathogens, or the toxins they produce, are communicable or infectious diseases (45). In this manual these will be called disease and infection. This chapter presents the transmission cycle of disease with its different elements, and categorises the different infections related to WES. 2.1 Introduction to the transmission cycle of disease To be able to persist or live on, pathogens must be able to leave an infected host, survive transmission in the environment, enter a susceptible person or animal, and develop and/or multiply in the newly infected host. The transmission of pathogens from current to future host follows a repeating cycle. This cycle can be simple, with a direct transmission from current to future host, or complex, where transmission occurs through (multiple) intermediate hosts or vectors. This cycle is called the transmission cycle of disease, or transmission cycle. The transmission cycle has different elements: The pathogen: the organism causing the infection The host: the infected person or animal ‘carrying’ the pathogen The exit: the method the pathogen uses to leave the body of the host Transmission: how the pathogen is transferred from host to susceptible person or animal, which can include developmental stages in the environment, in intermediate hosts, or in vectors 7 CONTROLLING AND PREVENTING DISEASE The environment: the environment in which transmission of the pathogen takes place.

Infectious Diseases of Poverty (2019) 8:86 https://doi.org/10.1186/s40249-019-0599-4 SCOPING REVIEW Open Access Neglected tropical diseases in the People’s Republic of China: progress towards elimination Men-Bao Qian1, Jin Chen1, Robert Bergquist2, Zhong-Jie Li3, Shi-Zhu Li1, Ning Xiao1, Jürg Utzinger4,5 and Xiao-Nong Zhou1* Abstract Since the founding of the People’s Republic of China in 1949, considerable progress has been made in the control and elimination of the country’s initial set of 11 neglected tropical diseases. Indeed, elimination as a public health problem has been declared for lymphatic filariasis in 2007 and for trachoma in 2015. The remaining numbers of people affected by soil-transmitted helminth infection, clonorchiasis, taeniasis, and echinococcosis in 2015 were 29.1 million, 6.0 million, 366 200, and 166 100, respectively. In 2017, after more than 60 years of uninterrupted, multifaceted schistosomiasis control, has seen the number of cases dwindling from more than 10 million to 37 600. Meanwhile, about 6000 dengue cases are reported, while the incidence of leishmaniasis, leprosy, and rabies are down at 600 or fewer per year. Sustained social and economic development, going hand-in-hand with improvement of water, sanitation, and hygiene provide the foundation for continued progress, while rigorous surveillance and specific public health responses will consolidate achievements and shape the elimination agenda. Targets for poverty elimination and strategic plans and intervention packages post-2020 are important opportunities for further control and elimination, when remaining challenges call for sustainable efforts.
