Un aspecto de la seguridad alimenticia es la necesidad de un monitoreo comprensivo de los residuos de pesticidas en alimentos. Los analistas de residuos de pesticidas estan constantemente desafiados a detectar, identificar y cuantificar cientos de pesticidas de diferentes clases de compuestos en bajas concentraciones, en diverso tipos de muestras, con rápidos tiempos de entrega y a un costo aceptable. Un monitoreo verdaderamente comprensivo requiere de análisis tanto por técnicas de Cromatografía Gaseosa (GC), como de Cromatografía Líquida (GC). También requiere el uso de análisis dirigidos (para análisis de rutina de compuestos conocidos) y también enfoques no dirigidos (para la detección de compuestos inesperados o ilegales).
Este diálogo intercativo presentará cuatro expertos mundiales de renombre en el campo de la seguridad alimenticia y análisis de pesticidas, quienes desarrollarán los aspectos críticos del flujo de trabajo en análisis de pesticidas necesarios para alcanzar resultados válidos y comprensivos. Los expertos debtirán la preparación de muestras, extracción de muestras, y procedimientos de limpieza, incluyendo la opción y optimización de combinaciones de solventes y reagentes. También discutiran la evolucion de los análisis para pesticidas de residuos múltiples, tanto LC-MS/MS como GC-MS/MS, con enfoque en los nuevos desarrollos en instrumentación de espectrometría de masas de alta resolución de masa exacta (HRAM) y también los requerimientos de software necesarios para desarrollar soluciones de screening innovadoras, comprensivas y costo-efectivas.
Asistiendo a esta mesa redonda usted obtendrá información valiosa con respecto al desarrollo y la optimización de flujos de trabajo de métodos, puntos de control críticos de los métodos y soluciones a los desafíos frecuentemente encontrados. También ganara un mejor entendimiento de los requerimientos necesitados para la validación y un control de calidad contínuo, y cómo la implementación de GC y LC Triple Cuadrupolo, HRAM y tecnologías de software son utilizados para resolver los mas complejos problemas analíticos.

Dr. Katerina Mastovska is an Associate Scientific Director at Covance Laboratories. She is responsible for the development of new analytical methods and strategies for testing chemical residues, contaminants, and adulterants in food and food supplements. Prior joining the Nutritional Chemistry and Food Safety business unit at Covance Laboratories in 2009, she worked at the U.S. Dept. of Agriculture (USDA) where she served as an expert in the United Nation’s Food and Agricultural Organization (FAO) panel of the Joint FAO/WHO Meeting on Pesticide Residues (JMPR). Dr. Mastovska is also a Fellow of the AOAC International where she co-chairs the AOAC Chemical Contaminants and Residues in Food community. Dr. Mastovska has authored or co-authored more than 50 scientific publications (journal articles, book chapters, and monographs) and well over 100 conference presentations. She received her Ph.D. in Food Chemistry and Analysis from the Institute of Chemical Technology in Prague, Czech Republic.
Dr. Hans Mol is senior scientist at RIKILT-Wageningen UR (Wageningen, the Netherlands) with 20 years of experience in food safety analysis. He is responsible for analytical method development, validation, and quality control, as well as analytical services in the field of residues and contaminants. His main emphasis is on pesticides, mycotoxins, and plant toxins in food, feed, and related matrices. His key techniques are chromatography with various types of mass spectrometric detection, and rapid MS-based screening methods. He heads the National Reference Laboratory for Mycotoxins and the National Reference Laboratory for Pesticides in products of animal origin. He is active in many national and international research projects, amongst others in the framework of EU (FP7), EFSA, and CEN projects as work package leader, coordinator, and project leader. He is an active member in EU working groups on analytical quality control in the fields of pesticides and mycotoxins and is involved in technical training and consultancy within these domains.

His EURL responsibilities include building the network of official laboratories, providing assistance and training to National Reference Laboratories (NRLs), developing methods for pesticide residue analysis, organizing EU Proficiency Tests, drafting and updating the EU guidelines (SANTE/11945/2015) on method validation and quality control procedures for pesticides residues analysis in food and feed . During the period 2008-2012, he was the head of the Laboratory for Mass Spectrometry at the Insituto Madrileño de Estudios Avanzados (IMDEA-Water). Prof. Fernandez-Alba is the vice president of the Environmental Education Assessment and Protection Committee. He is also a current member of AENOR (the Spanish standardization body), CEN (the European standardization body), the Committee of the Spanish Mass Spectrometry Association, and also the Committee of the Latin American Pesticide Residue Workshops. Prof. Fernandez-Alba has contributed to 24 book chapters and authored and co-authored 244 scientific publications 326 poster presentations. He has also presented more than 50 invited lectures at national and international conferences. Prof. Fernandez-Alba obtained a chemistry degree at the University Complutense of Madrid and his PhD from the University of Granada.
Walter Hammack is an Environmental Manager with the Florida Department of Agriculture’s Division of Food Safety and Chemical Residue Laboratory.
