Guidance on the Risk Assessment of Genetically Modified Microorganisms 1 3 and Their Food and Feed Products EFSA Journal 20YY;volume(issue):NNNN 1 SCIENTIFIC OPINION 2 Guidance on the risk assessment of genetically modified microorganisms 1 3 and their food and feed products 4 EFSA Genetically Modified Organisms (GMO)2, 3 5 European Food Safety Authority (EFSA), Parma, Italy 6 ABSTRACT 7 The EFSA Panel on Genetically Modified Organisms (EFSA GMO Panel) published its first 8 Guidance Document for the risk assessment of genetically modified microorganisms and their 9 derived products intended for food and feed use in October 2006. Since then, the EFSA GMO 10 Panel has gained significant experience in assessing applications for marketing food and feed 11 involving genetically modified microorganisms within the EU, which has enabled it to 12 identify areas of the Guidance that needed clarification and issues that should be covered 13 more in depth. In addition, the Panel has received and acknowledged input from different 14 stakeholders, and considered recent developments in relevant European legislation. This 15 revised document provides updated guidance for the preparation and presentation of 16 applications for science-based risk assessment. It describes the steps to be taken and the 17 issues to be considered when carrying out a comprehensive risk characterisation. 18 © European Food Safety Authority, 2010 19 KEY WORDS 20 GMOs, GM microorganisms, GM food and feed, guidance, Regulation (EC) No 1829/2003, Directive 21 2001/18/EC, food safety, feed safety, environment. 1 On request from EFSA, Question No EFSA-Q-2009-521, adopted on DD Month YYYY. 2 Panel members: Hans Christer Andersson, Salvatore Arpaia, Detlef Bartsch, Josep Casacuberta, Howard Davies, Patrick du Jardin, Gerhard Flachowsky, Lieve Herman, Huw Jones, Sirpa Kärenlampi, Jozsef Kiss, Gijs Kleter, Harry Kuiper, Antoine Messéan, Kaare Magne Nielsen, Joe Perry, Annette Pöting, Jeremy Sweet, Christoph Tebbe, Atte Johannes von Wright, and Jean-Michel Wal.

Available online: www.efsa.europa.eu/efsajournal.htm © European Food Safety Authority, 20YY 1 Guidance on the risk assessment of GMMs and their food and feed products 22 SUMMARY 23 The European Food Safety Authority (EFSA) asked the EFSA Panel on Genetically Modified 24 Organisms (EFSA GMO Panel) to establish a self-tasking Working Group with the aim of 25 updating the Guidance Document for the risk assessment of genetically modified 26 microorganisms and their derived products intended for food and feed use. The aim of the 27 Working Group was to provide updated guidance for the preparation and presentation of 28 applications involving genetically modified microorganisms (GMMs). 29 30 To complete its mandate, the self-tasking Working Group: i) reviewed the existing Guidance 31 Document, and identified areas of improvement, ii) considered input received from the 32 Member States and applicants on the existing Guidance Document and iii) discussed and 33 developed improvements for those areas. 34 35 The EFSA GMO Panel published its first Guidance Document for the risk assessment of 36 genetically modified microorganisms and their derived products intended for food and feed 37 use in October 2006. This revised document was adopted on (XX-XX-XXXX). The EFSA 38 and the EFSA GMO Panel published the Guidance on the EFSA web site for public 39 consultation prior to the final adoption of this document. 40 41 Updated guidance for the preparation of applications is given throughout the different 42 chapters of the guidance document. Chapter I clarifies the scope of the document and the 43 regulatory background for the risk assessment of GMMs and their food and feed products at 44 the Community level. Chapter II describes the overall risk assessment strategy. Chapter III 45 describes the steps to be taken and the issues to be considered when carrying out a 46 comprehensive risk characterisation. These issues include general information, information 47 relating to the recipient/parental, the donor(s) of the genetic material, the genetic modification 48 and the final GMM, as well as information relating to the food and/or feed containing, 49 consisting of, produced from and produced with GMMs4. It also includes information on 50 modification of the genetic traits or phenotypic characteristics of the GMM and evaluation of 51 food and feed safety aspects of the GMM and derived products5. Data on composition, 52 toxicity, allergenicity, nutritional value and environmental impact provide, on a case-by-case 53 basis, the cornerstones of the risk assessment process. The characterisation of risk may give 54 rise to the need for further specific activities including post-market monitoring of the GMM 55 and derived food and feed and/or for the environmental monitoring of the GMM. A table 56 (Table 1) summarising the risk assessment requirements for the different categories of GMMs 57 and their products is also provided. 58 59 4 Regulation (EC) No 1829/2003 defines food and feed ‘produced from GMOs’ as derived, in whole or in part, from GMOs, but not containing or consisting of GMOs. “Containing or consisting of GMMs” is understood as products in which GMMs capable of replication or of transferring genetic material are present. “Produced with GMMs” is understood as produced by fermentation using a GMM which is kept under contained conditions and is not present in the final product. Such products are not included in the scope of Regulation (EC) No 1829/2003 (EC, 2004). 5 According to Regulation (EC) No 1829/2003 “Derived (food and/or feed) products” is understood as products containing, consisting of or produced from GMMs, but not produced with GMMs. EFSA Journal 20YY;volume(issue):NNNN 2 Guidance on the risk assessment of GMMs and their food and feed products 60 TABLE OF CONTENTS 61 Abstract ................................................................................................................................................ 1 62 Key Words ........................................................................................................................................... 1 63 Summary .............................................................................................................................................. 2 64 Table of contents .................................................................................................................................. 3 65 Background as provided by the EFSA GMO Panel ............................................................................. 5 66 Terms of reference as provided by the EFSA GMO Panel .................................................................. 5 67 I.

Well, imagine it to be a lot like visiting a supermarket. You choose the goods you want and take them to the cashier. Usually you have to pile them onto a conveyor. The clerk picks up one item at a time and interrogates it with a laser to read the barcode. Once identified and if sense prevails, similar goods are collected together e.g. fruit and vegetables go into one shopping bag and household goods into another. Now picture in your mind the whole process automated; replace shopping with biological cells; and substitute the barcode with cellular markers – welcome to the world of flow cytometry and cell sorting! We aim to give you a basic overview of all the important facets of flow cytometry without delving too deeply into the complex mathematics and physics behind it all. For that there are other books (some recommended at the back).

  • Flow Cytometric Determination for Dengue Virus-Infected Cells: Its Application for Antibody-Dependent Enhancement Study
    Flow Cytometric Determination for Dengue Virus-Infected Cells: Its Application for Antibody-Dependent Enhancement Study Kao-Jean Huang*, Yu-Ching Yang*, Yee-Shin Lin*, Hsiao-Sheng Liu*, Trai-Ming Yeh**, Shun-Hua Chen*, Ching-Chuan Liu*** and Huan-Yao Lei*! *Departments of Microbiology and Immunology, College of Medicine, National Cheng Kung University, Tainan, Taiwan **Department of Medical Technology, College of Medicine, National Cheng Kung University, Tainan, Taiwan ***Department of Pediatrics, College of Medicine, National Cheng Kung University, Tainan, Taiwan Abstract The theory of antibody-dependent enhancement plays an important role in the dengue virus infection. However, its molecular mechanism is not clearly studied partially due to lack of a sensitive assay to determine the dengue virus-infected cells. We developed a flow cytometric assay with anti-dengue antibody intracellular staining on dengue virus-infected cells. Both anti-E and anti-prM Abs could enhance the dengue virus infection. The anti-prM Ab not only enhanced the dengue virus infected cell mass, but also increased the dengue virus protein synthesis within the cells. The effect of anti-prM Ab- mediated enhancement on dengue virus infection is serotype-independent. We concluded that the target cell-based flow cytometry with anti-dengue antibody intracellular staining on dengue virus- infected cells is a sensitive assay to detect the dengue virus infected cells and to evaluate the effect of enhancing antibody on dengue virus infection on cell lines or human primary monocytes. Keywords: Dengue, enhancing antibody, ADE, flow cytometry. Introduction characterized by abnormalities of haemostasis and increased vascular permeability, which in Dengue is an acute infectious disease caused some instances results in DSS.

  • The Acceptable Daily Intake (ADI)
    Appendix 1- Definitions and glossary of terms Acceptable Daily Intake (ADI) The Acceptable Daily Intake (ADI) for humans is defined as an estimate of the amount of a chemical that can be ingested daily over a lifetime without appreciable risk to health (WHO 2001). ADIs are set using information obtained from toxicological studies, including data from studies on various laboratory animals. From these studies, a No Observable Effect Level (NOEL) is established. The NOEL is the highest dose level that produces no observable toxic effect in the most sensitive test species and is expressed in milligrams per kilogram of body weight per day (mg/kg bw/day). The ADI is derived by applying a safety factor to the NOEL. The safety factor takes into consideration the nature of the effect, differences between laboratory test animals and humans, and genetic variation in the human population. If any information on exposure in humans is available, usually from short to mid-term studies, this will be used to set the ADI. The unit for the ADI is milligrams per kilogram of body weight per day. Limit of Detection (LOD) The LOD is the lowest concentration of a chemical that can be qualitatively detected using a specified laboratory method and/or item of laboratory equipment (i.e. its presence can be detected but not quantified). For the purposes of this study, analytical results reported as being less than the LOD were assumed to be zero. Limit of Quantification (LOQ) The LOQ is the lowest concentration of a chemical that can be detected and quantified, with an acceptable degree of certainty, using a specified laboratory method and/or item of laboratory equipment.

  • Introduction to Flow Cytometry
    Introduction to flow cytometry Flow cytometry is a popular laser-based technology. Discover more with our introduction to flow cytometry. Flow cytometry is now a widely used method for analyzing the expression of cell surface and intracellular molecules, characterizing and defining different cell types in a heterogeneous cell populations, assessing the purity of isolated subpopulations and analyzing cell size and volume. It allows simultaneous multi-parameter analysis of single cells. It is predominantly used to measure fluorescence intensity produced by fluorescent-labeled antibodies detecting proteins, or ligands that bind to specific cell-associated molecules such as propidium iodide binding to DNA. The staining procedure involves making a single-cell suspension from cell culture or tissue samples. The cells are then incubated in tubes or microtiter plates with unlabeled or fluorochrome-labeled antibodies and analyzed on the flow cytometer. Contents The flow cytometer: fluidics The flow cytometer: measurement of forward and side scatter of light The flow cytometer: measurement of scatter light and fluorescence Antibody staining Selecting a fluorochrome conjugate Discover more at abcam.com 1 of 8 The flow cytometer: fluidics Figure 1. Overview of the flow cytometer. Sheath fluid focuses the cell suspension, causing cells to pass through a laser beam one cell at a time. Forward and side scattered light is detected, as well as fluorescence emitted from stained cells. When a cell suspension is run through the cytometer, sheath fluid is used to hydrodynamically focus the cell suspension through a small nozzle. The tiny stream of fluid takes the cells past the laser light one cell at a time (Figure 1).
