Contact Author Genetically Modified Foods: To Eat, or Not To Eat? To eat genetically modified foods or not to eat, that is a question on the minds of many people around the world today.
It has become difficult to avoid consuming these products simply because GM varieties are what farmers are planting. Source Genetically Modified Foods: What Are We Afraid Of?
Why are people so concerned about genetically modified foods? What are they afraid of? While these may be legitimate concerns, they are not what genetic modification is about.
Three Areas of Concern What are the real concerns about genetically modified crops and the foods derived from them? There are three primary areas of concern. The effect on the environment. There is the fear that certain traits of GM crops might be introduced into the wild.
The effect on the human body. Antibiotic resistant bacteria are often used to mark genetically modified plant cells. Will this trait affect the good bacteria in the human digestive tract? Are genetically modified foods one of the reasons antibiotics are not as effective at fighting certain infections as they used to be?
The unintended effects on the plants themselves. By adding a new protein to a plant, are we turning a nonallergenic plant into an allergenic plant which could become a health concern to consumers?
Source The Effect on the Environment The issue: Certain genetic modifications of food crops may be able to spread to wild plants via cross pollination, introducing manmade character traits into nature. A National Public Radio report disclosed that canola plants in North Dakota, which are grown for canola oil, have been genetically modified to withstand the effects of herbicides.
Those new genes have now been found in wild canola plants making it difficult to control their growth.
The cause for concern: Genetically modified plants grown on farms are given traits that will make them resistant to the effects of herbicides, pesticides and drought. If and when these plants cross pollinate with wild plants, the same traits may then be introduced to wild plants, i.
Scientists make genetic modifications in certain plants. These modifications are made in individual cells of that plant. How do they know that the new plant has cells containing the modifications? The modified cells are made to be antibiotic resistant while cells that did not accept the modifications will not have antibiotic resistance.
An antibiotic is then introduced among the cells. Those with resistance, which also have the desired modification, survive. If no cells survive, the genetic modification failed.
A further complication with the maize is that the material was intended to be used unprocessed in animal feed and that the antibiotic resistance gene was under the control of a bacterial promoter.Yet pesticides are still found daily in foods all around the world.
Pesticides are toxins that are used by produce growers universally to control pests that can destroy . To eat genetically modified foods or not to eat, that is a question on the minds of many people around the world today.
It has become difficult to avoid consuming these products simply because GM varieties are what farmers are planting. The use of pesticides was not as common 10, years ago as it is today.
Around "pesticides became common in most areas of the world" (W.R. Carlile). Pesticides are used to prevent unwanted pest (living organisms that occur where they are NOT wanted or . Bacillus thuringiensis produces a variety of different toxins during its vegetative cell state and sporulation.
The crystalline proteins, shown in figure 3, are the typical toxins . Aug 13, · SRO: My introduction to toxins in the environment was in college actually when I started doing work study on organic contaminants in sewage sludge.
Food and Pesticides. Pesticides are widely used in producing food to control pests such as insects, rodents, weeds, bacteria, mold and fungus. EPA must ensure that all pesticides used on food in the United States meet FQPA's stringent safety standard.
