Genetic modification is the technology by which the genetic makeup of the living organism such as plants and animals bacteria is changed. Thus the resultant organism is called genetically modified, genetic engineered or transgenic. Source citation (http://www. ext. colostate. edu/pubs/foodnut/09371. html).
First of all Consumers have a right to know whats in their food, especially concerning products for which health and environmental concerns have been raised, this I think is one of the most important reason why individuals will prefer the labeling of genetically modified food, and also to know the condition of the environment of which the product was made from weather is a place with good sanitation or not.
Mandatory labeling will allow consumers to identify and steer clear of food products that cause them problems because some people who with medical problems or allergic to some product will have to know before using them in order not to get themselves in trouble or contracting any form of diseases Surveys indicate that a majority of Americans support mandatory labeling. (However, such surveys often do not specify the effect on food prices.)
Least 21 countries and the European Union have established some form of mandatory labeling source citation (Gruere and Rao, 2007; Phillips and McNeill, 2000) For religious or ethical reasons, many Americans want to avoid eating animal products, including animal DNA. For example some religious beliefs enact laws for people to avoid eating some certain products due to this labeling of genetically modified food will help consumers know the right choice of product to consume example are the jewish and the buddist.
