October is a month of harvest and National Non-GMO Month promotes awareness about Genetically Modified Organisms (GMO). GMOs are also known as bioengineered crops and food. A GMO is an organism that has been genetically modified in a laboratory using bioengineering. GMO foods have been on the market since 1994, but food labeling regarding GMOs didn’t arrive until 2016.

GMO Timeline
  • 1982 – The FDA approves genetical modified human insulin – the first consumer GMO product.
  • 1992 – FDA updates its policy to state that foods from GMO plants must meet the same safety standards as non-GMO foods.
  • 1994 – Calgene introduces the first GMO crop – the Flavr-Savor tomato.
  • 2003 – The World Health Organization (WHO) and the United Nations develop international guidelines and standards for GMO food safety.
  • 2016 – The U.S. Congress passes the National Bioengineered Food Disclosure Law requiring labeling of genetically engineered foods.

A variety of foods in the U.S. are genetically engineered and many of them are ingredients in the foods we eat. Some of the most common GMO crops are:

  • Soybeans
  • Corn
  • Sugar beets
  • Canola
  • Cotton

But there are several more and the Agricultural Marketing Service of the USDA maintains a list that consumers can review. The observance provides an opportunity to learn more about food labeling and to exercise their consumer choice.
