Evaluation of Residual Pesticides and Heavy Metals Levels in Conventionally and Organically Farmed Potato Tubers in Egypt

  • Sameeh A. Mansour
Chapter

Abstract

Egypt is one of the top 10 potato exporting countries in the world. The increasing demand of food safety has stimulated research regarding the risk associated with consumption of foods contaminated by pesticides and heavy metals. Egypt, like many other countries, is moving towards production of organic crops along with traditional ones. This chapter examines and discusses contamination levels of pesticides and heavy metals in potato tubers in Egypt. As there is a widespread belief that organic agriculture products are safer and healthier than conventional foods, this chapter comparatively analyzes the data of pesticides and heavy metals in conventionally and organically farmed potato tubers produced by the chapter author and his colleagues. Information in this chapter shows it is difficult to come to conclusions, but what should be made clear to the consumer is that “organic” does not automatically equal “safe”. More research efforts are needed to evaluate and assure sustainable production of high quality and safe potato from both conventional and organic farming practices.
