What is Genetic modification?

Genetically modified (GM) organisms are plants, animals or microorganisms in which their DNA has been modified in a way that does not occur naturally. The process of genetic manipulation involves the translocation of genes from multiple genetic sources in a process widely known as recombinant DNA technology (Bawa & Anilakumar, 2013). This process is sometimes referred to as genetic engineering, modern biotechnology or gene technology (WHO, 2016). Genetic modification allows selected individuals genes to be transferred from one organism into another, also between non-related species. Food produced from using GM organisms are often referred to as GM foods.

Genetic engineering used to produce plants that produce their own insecticides. The bt toxin gene, which encodes an insecticide, was isolated from bacteria and transferred to tobaccop plants. (Pierce genetic conceptual approach, page 526) 



























Examples of GMO in Europe and UK
GM crops have been used as food sources for many years around the world. Since November 2015 the first GM animal in the US, in this case GM salmon was approved for human consumption by the US food and drug administration (Nature, 2015). Although no GM animals have been approved in Europe, it still produces GM crops and allows the import of GM products such as cotton, maize, yeast biomass, oilseed rape, sugar beet and soybean from other countries (EU Plants, 2016). Spain is the largest producer of GM crops in Europe with a hectare of 0.1 used for GM maize (ISAAA, 2013). However, small amounts less than 0.1 hectare are grown in Slovakia, Romina, Poland and Czech Republic (ISAAA, 2009).
Large amounts of GM foods such as soya and maize are imported into Europe including Britain to be used as animal feed. In the UK, meat and dairy products that are fed on GM feed are not labelled. Most of the main supermarkets in the UK such as Asda, Aldi, Tesco, Co-op, M&S and Morrison’s have meat and dairy products that are fed on GM food (Gmfreeze, 2015). One of the most consistently stocked GM items in UK supermarket is cooking oil. Most retailers in UK do not sell any other GM foods and if they do then labelling is required.

  1. That's a good read, we'll add it to the poster on Wednesday. I have some more information I'll incorporate in and we'll finalise it all.
    We also need to do Harvard referencing on the links which we can do on Wed.
