Genetic modifications have existed for as long as
humans have cultivated plants. Traditionally, cross-breeding plants genetically modified
them to create greater yields and higher quality. Bioengineering speeds this process by taking genes for
traits in one organism and inserting them into another organism lacking these genes.
Genetic modifications using bioengineering has two purposes. To improve or correct genetic defects, or Genetically modify organisms.
Genetic Modification
![Page 3: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/3.jpg)
“The process of breeding staple crops to have higher levels of essential
nutrients, either through selective breeding or genetic modification.
Biofortification
![Page 4: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/4.jpg)
Food security in developing countries. Creation of superior plants resistant to pests and
disease; thus, reduction of the use of pesticides and their harmful environmental effects.
Reduction of costs to farmers and customers. Increase in the nutrient and vitamin content of
foods. Alleviation of nutrient deficiencies around the
world.
Purpose of GMOs
![Page 5: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/5.jpg)
Fortified vs. Enriched
Fortification:A strengthening or
improvement, as by addition of or
intensification with another ingredient to increase nutritional
value.
Enrichment:The replacement of lost nutrients during the refining process, making foods finer in quality by supplying
desirable elements or ingredients.
![Page 6: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/6.jpg)
Zinc: Protein synthesis, DNA replication
and metabolism. Iron: Oxygen transport, regulation of
cell growth and differentiation. Beta-carotene: Precursor to vitamin A. Folic Acid & Vitamin B12: Reduce the
risk of neural tube defects. More recent target of biofortification.
Physiological Roles of Essential Micronutrients Targeted in GMO Foods

Potential Hazards of
Biofortification Sources:
Parent host (traditionally bred crops), gene donor, transformed crop
Types: Gene transfer to bacteria or
mammalian cells Nutritional changes or anti-
nutrient effects Toxicity including allergenicity
Potential Targets: Farmers Processors Consumers Animals

The US Food and Drug Administration (FDA) has
the ultimate responsibility to evaluate GM foods and deem them safe for human consumption or not. The FDA is responsible for regulating labeling practices as well.
The United States Department of Agriculture (USDA) evaluates the safety of growing GMOs.
The Environmental Protection Agency evaluates the environmental safety of GMOs.
Safety of GMO Foods
![Page 9: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/9.jpg)
Current FDA policy: GM food is
‘substantially equivalent’ to non GMO food. No labeling or safety testing required.
Conflict of interest? Michael R. Taylor, former VP of Policy at Monsanto, has been the Deputy Commissioner of Foods (FDA) since 2010. http://www.fda.gov/AboutFDA/CentersOffices/OfficeofFoods/ucm196721.htm
Why loosen current regulations? During 2011, deregulation of sugar beet and alfalfa crops occurred in the US with no investigation into the potential dangers of either crop.
GMO Regulation: United States
![Page 10: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/10.jpg)
GMO Labeling:
California’s Prop 37
Proposed the labeling of GM ingredients in food products sold in supermarkets.
![Page 11: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/11.jpg)
Rejected by voters (53% against, 47% in support). Corporate campaigning:
$45 million spent to fight the GMO labeling initiative versus $8 million spent to support the campaign.
‘No’: Monsanto ($7.1 m), Dupont de Nemours ($4.9 m), PepsiCo ($2.14 m), Kraft ($1.6 m)
‘Yes’: Organic Consumers Fund ($1.034 m), Co-founder of Seed Saver Exchange ($1 m), Nature’s Path Foods, Inc. ($1.15 m)
(Breakdown of money spent)
Significance of Prop 37
![Page 12: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/12.jpg)
Mandatory Labeling Arguments
Pro-labeling: Consumers have the
right to know what’s in their food, especially foods with health and environmental concerns involved.
Anti-labeling: No significant difference
between conventional foods versus GM foods.
Costly to consumers and companies for mandatory testing and labeling of products.
‘100% Organic’ offers consumers the option of purchasing non-GM foods.
![Page 13: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/13.jpg)
Regulation Abroad
US first exported GM food to Europe in 1996. Britain followed with mandatory labeling in 1997.
Mandatory labeling: European Union, Australia, New Zealand, Japan, South Korea, Indonesia It’s an issue over consumer
choice and consumer rights, not health.

Products:
Agricultural and vegetable seeds Plant biotechnology traits Crop protection chemicals
Globally: 21,035 employees 404 facilities in 66 countries
Controls ~90% of global seed genetics. http

Monsanto discovered glyphosate:
Active ingredient in Roundup® formula. Successful in killing weeds/roots. Decreases space between crops and increases
crop yield. Requires only one spraying per crop. Roundup represents 50% of Monsanto’s
revenue. Thus, GM seeds developed to withstand
herbicide.
Roundup® herbicide formulation
![Page 16: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/16.jpg)
Compared the health effects in three groups (rats):
GM maize cultivation with Roundup GM maize cultivation without Roundup Control group (Conventional maize without
Roundup) Study lasted two years (typical rat lifespan). Rats in the first two groups were 2-3 times more likely
to have enhanced tumor production compared to the control group.

GM Maize Study: “Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize”
![Page 17: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/17.jpg)
It did not meet acceptable standards and findings
are not supported by the data presented. Breed of rats is known for developing tumors Type of corn used was not specified Research protocol does not meet OECD standards
Lifetime cancer studies previously done have shown glyphosate does not cause tumors or cancer in rodents.
Published epidemiology studies evaluating health effects reinforce the lack of evidence linking glyphosate to tumors or cancer.
Monsanto’s Response:Limitations of Study
![Page 18: Safety and Regulation of GMO Foods](https://reader036.fdocuments.net/reader036/viewer/2022062815/568168f2550346895ddff965/html5/thumbnails/18.jpg)
More research is needed.
Agricultural GMOs and corresponding pesticides must be evaluated carefully with long term studies to measure potential toxic effects.
