A trip to any supermarket in Canada will reveal nothing out of ordinary, just the usual of array of fresh and packaged goods displayed in an inviting manner to attract customers. Everything appear familiar and reassuring, right? Think again. A closer microscopic inspection discloses something novel, a fundamental revolution in food technology. The technology is genetic engineering (GE), also known as biotechnology. Blue prints (DNA) of agricultural crops are altered and “spliced” with foreign genes to produce transgenic crops. Foods harvested from these agricultural plants are called, genetically modified (GM). Presently, Canada has no consumer notification; GM foods are being slipped to Canada’s foods without any labels or adequate risk assessments. This essay argues that GM foods should be rigorously and independently tested for safety; and, consumers be given the right to choose or reject GM foods through mandatory labels. What is the need for impartial examination of safety of transgenic foods? And why label them? GM foods are not “substantially equivalent” to conventional foods, genetic engineering of agricultural crops is not a mere extension of traditional plant breeding, and finally, there are human health implications associated with it.
Modern biotechnology was born at the hands of American scientists Herb Boyer and Stain Cohen, when they developed “recombinant deoxyribonucleotide, (rDNA), [1] for medicinal purposes. Subsequently, biotechnologists started genetically engineering agricultural plants using this technology. A single gene responsible for a certain trait, from one organism (usually a bacterium) is selected altered and then ‘spliced” into the DNA of a plant to create an agricultural crop consisting of that...

...ad in the powerful world of genetic modification with caution. Health Canada should follow the “precautionary principle” just like the European Union nations. Under this principle, a transgene food is segregated from its traditional counterparts, and is prevented from entering consumer market until unbiased risk assessments test can vouch for its safety. European Union safety authority, (EFSA), strictly regulates GM foods; only a handful of GM foods are released into the market . Most importantly, all food products containing more than 0.9 percent of GMO’s (genetically modified organisms) are labelled [brown journal of world affairs]. GM foods are scrutinized even further by a post market monitoring plan. Like EU, Canadian regulatory agencies should respect consumers’ right to know what they are eating by labeling all foods containing altered gene materials.
A non-GMO label doesn’t necessarily mean “healthy”. White sugar, flour, and processed ingredients if not genetically modified are considered non GMO. Recently Cheerios made their ingredients GMO free. This label made Cheerios seems as a “healthy conscience choice” when in fact they are not healthy at all. The truth is that this breakfast cereal is highly processed and is best to be avoided despite the “healthy halo” of being approved by the National Heart Association and GMO free. The truth appears on the nutrition label and the ingredients (Wartman). “If you can’t pronounce it, don’t buy it” The voluntary labeling places a burden on the consumer. The average Americans are forced to navigate confusing and cluttered food landscape” (Wartman). A mandatory labeling law is vital to give clear and concise information to citizens.
Pamela Ronald, a plant geneticist, presented a Ted Talk “The case for engineering our food”, Ronald points out that engineered genetics for our plants is not harmful, yet better for our environment and health. “Now, genetic modification is not new; virtually everything we eat has been genetically modified in some manner”(Ronald).
Next, companies that refuse the use of genetic modifications on their foods must begin to label foods that do not contain GMOs so that consumers can be sure of their safety, even if others that contain GMOs do not label. Due to this labeling, there will be an exposure to which foods are natural because the foods that are the most appealing will have “the ‘Non-GMO Project Verified’ seal [in order] to help shoppers recognize which products meet rigorous GMO avoidance practices” (“Whole Foods Market”).

The Controversy Over Genetically Modified Foods The genetic engineering of foods has, in one sense, been in existence for hundreds of years. The first time Gregor Mendel bred different varieties of pea plants to observe the various traits present in their offspring, the concept was born. Today, genetic engineering has developed into one of the most complex and advanced fields of scientific thinking, all the while provoking many questions and acquiring many opponents along the way. While there are compelling arguments presented for each side of the issue, the simple fact is that genetically modified (GM) foods are a reality, especially in the United States, as they are already present in many products that are consumed on a daily basis.
Are genetically modified foods safe? Genetically modified foods are crop plants created for human or animal consumption using molecular biological techniques. These plants have been modified to enhance certain traits like increased resistance to herbicides or improve nutritional content. This process traditionally has been done through breeding, but is not very accurate. Scientists have been using biotechnology to implant the gene that makes the plants act the way they want them to. Genetically modified foods have advantages and disadvantages on the environment and advantages and disadvantages on society. We have to weigh the positives and negatives to see if genetically modified foods are healthy for us and if we really need them.
Food is an essential part of everyday life without it one could not survive. Every day we make choices on what we put in to our bodies. There are countless varieties of food to choose from to meet the diverse tastes of the increasing population. Almost all food requires a label explaining the ingredients and the nutritional value allowing consumers to make informed decisions on what they are consuming. However, many may not be considering where that food is coming from or how it has been produced. Unfortunately, there is more to food than meets the eye. Since 1992, “ the U.S. Food and Drug Administration ruled, based on woefully limited data, that genetically modified foods were ‘substantially equivalent’ to their non-GM counterparts” (Why to Support Labeling). GM food advocates have promised to create more nutritious food that will be able to grow in harsh climate conditions and eventually put an end to world hunger in anticipation of the growing population. There is very little evidence to support these claims and study after study has proven just the opposite. GM crops are not only unsafe to consume, but their growing practices are harmful to the environment, and multinational corporations are putting farmers out of business.
In the U.S., GM foods have received little public opposition; this is largely due to the fact that food manufacturers are not required to label their products as containing genetically modified ingredients for fear of confusing consumers. Due to the lack of evidence that genetically altered foods are harmful, the Food and Drug Administration considers GM foods to be “generally regarded as safe” (known as GRAS) and no special labeling is required (Falkner 103). In the U.S., genetically modified crops are monitored by t...
From the Flavr Savr ™ tomato to the more recent genetically modified corn, genetic engineering has been around for about 20 years. Now, do you really know what GMOs (genetically modified organisms) are? Do you understand both the pros and the cons are? Are you positive that GMOs mat or may not affect your health or the enviroment? If you answered no to any of these questions I strongly suggest you continue reading.
If people really knew what they were putting in their bodies when they ate, they probably would not want to eat it anymore. People don’t even know where their food is coming from, let alone know that their foods have been genetically modified. There are huge issues regarding the consumer’s health when eating these foods. For example, the animals wellbeing is not considered, and the environment is at risk. The United States food industry has become corrupt in so many ways; therefore, the consumer should buy from local farms to improve their health and ease their conscience.
The term GM foods or GMO (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman, 2000). These plants have been modified in the laboratory to offer desired traits such as increased resistance to herbicides or improved nutritional content. Also, genetic engineering techniques have been applied to create plants with the exact desired trait very rapidly and accurately. For example, this is done by the geneticist isolating the gene responsible for drought tolerance and inserts it into another plant. The new genetically-modified plant will now have gained drought tolerance as well.
“Genetically modified foods are a "Pandora's box" of known and unknown risks to humans and the environment. They have been forced onto the American public by multinational biotech and agribusiness corporations without adequate oversight and regulation by the United States government (Driscoll, SallyMorley, David C).”Genetically Modified Food is food which has been chemically altered by scientists during the production process to give the food more nutrients, better appearance, and a longer shelf-life (Rich, Alex K.Warhol, Tom). The importance of this issue is that these GMO’s can actually have a negative effect in our society in general. It could mutate in a negative way and cause cancer or other diseases. Genetically modified food should be strictly controlled due to its various detrimental effects on the environment, human health, and potentially insect/animal effects.
Agricultural biotechnology is a collection of scientific techniques, including genetic engineering, that are used to create, improve, or modify plants, animals, and microorganisms. Using conventional techniques, such as selective breeding, scientists have been working to improve plants and animals for human benefit for hundreds of years. Modern techniques now enable scientists to move genes (and therefore desirable traits) in ways they could not before - and with greater ease and precision (scope.educ.washington.edu).
What is the difference between a'smart' and a's PLANT CELL CULTURE AND APPLICATIONS a) Introduction b) Cell- and Tissue-Culture Techniques c) Applications of Cell and Tissue Culture d) Gene-Transfer Methods in Plants e) Transgenic Plants with Beneficial Traits f) Diagnostics in Agriculture and Molecular Breeding g) Bioethics in Plant Genetic Engineering PREFACES Biotechnology as a fast developing technology as well as a science has already shown its impact on different aspects of day-to-day human life such as public health, pharmaceuticals, food and agriculture, industry, bioenergetic Now it is very clear that biotechnology will be a key technology for the 21st century and the science of the future. It has the potential to ensure food security, dramatically reduce hunger and malnutrition, and reduce rural poverty, particularly in developing countries. Considering its commercial potential and its possible impact on the economy, the government has taken a number of measures to build up trained human resources in biotechnology and promote research and development and its commercial aspects.
Genetic engineering is a way in which specific genes for an animal or plant can be extracted, and reproduced to form a new animal or plant. These new organisms will express the required trait for that gene. This practice is a very controversial topic within the scientific world. It is being implemented in various areas such as agriculture, even though there are many alternatives that can be found for genetic engineered crops, such as organic materials and reducing leeching of the soil. The controversy regarding this practice occurs as it is believed to contribute both negative and positive implications and dangers, not only to oneself but the environment as a whole.
