With world food demands growing at unprecedented rates, biotechnology has taken a giant step into the future: genetic engineering. Not only do genetic modifications aim to increase crop production, but also enhance nutrient values and decrease pesticide applications. However, not all consumers see genetic engineering as a positive step. In fact, many are actually opposed to it. The most common complaints are centered on safety issues, as long term effects of genetically modified foods in terms of both health and the environment are largely unknown.

As a double major in Environmental Studies and Biology at St. Olaf College, I thought it would be interesting to look at some of the controversies surrounding genetically modified organisms, specifically in terms of product labeling. I wanted to research some background information and public opinions throughout the United States through a literature review; however, I also wanted to bring it all home to Northfield. I attempted to gain a more local perspective through interviews to local farmers, grocers, and consumers (St. Olaf students).

As defined by Measure No. 27 of Oregon's Nov. 2002 ballot, genetically engineered means "produced by biological changes to the molecular or cell biology of an organism by means not possible under natural conditions."

This "definition excludes breeding, hybridization, tissue culture, certain other processes." and "applies to all foods derived from, or prepared with, genetically-engineered material, regardless of whether that material is present in the final product."

For all extensive purposes, the following terms will be used interchangeably:
genetically modified (GM)
genetically modified organisms (GMOs)
genetically engineered (GE)
biotechnology, or transgenic technology.

To further clarify,
Breeding: organisms mate with other organisms of common ancestry; may include controlled mating, artificial selection, or hybridization to produce desirable offspring
Hybridization: crossbreeding; breeding between two different varieties or species
Tissue Culture: growing or keeping alive tissue in a medium outside of the organism

How to genetically modify food:

According to Dave Starck (of Monsanto), there are two basic ways of splicing genes into a plant. You can either infect it with agrobacterium (a pathogen that switches DNA with the plant’s nucleus) or shoot it with a gene gun (literally). This process is actually not entirely consistent; the gene transfer takes somewhere between 10-90% of the time. There are thousands of possible outcomes (Pollan 2001: 207-209).

Examples of GMOs:

Monsanto

  • Roundup Ready
  • Bollgard
  • YieldGard (bT or Bacillus thuringiensis)
  • YieldGard Rootworm Corn
  • Posilac (rBGH or recombinant bovine growth hormone, more specifically rBST (recombinant bovine somatotropin), sometimes called simply bST)
  • Genepacker

Bayer CropScience:

  • Nunhems (vegetable seeds for mainly onions, carrots, melons, and leeks)
  • FiberMax Cottonseed
  • InVigor canola
  • Hybrid rice seed

BASF

  • Clearfield (corn, wheat, rice, canola, and sunflower)
