Action Alert: Stop Registration of Bt Crops
August 6, 2001

Note: Comment period extended through September 10, 2001.

The U.S. Environmental Protection Agency (EPA) is currently determining whether genetically engineered insecticidal crops should continue to be grown in the United States. Because the permits under which the agency first approved insecticidal corn and cotton expire in 2001, EPA must decide in the near future whether or not — or under what conditions — to allow farmers to plant the crops in 2002 and beyond. Genetically Engineered Food Alert urges you to send comments to EPA before August 31, 2001.

To date, all commercialized genetically engineered insecticidal plants produce a type of Bt toxin, one of a family of related molecules produced by a soil bacterium, Bacillus thuringiensis (Bt). To develop what are known as Bt crops, a company clones the insecticidal gene from the bacterium and inserts it into a crop plant. The plant then produces the toxin in most, if not all, parts of the plant through all or most of a growing season.

Many nongovernmental organizations, scientists and farmers around the world are opposed to the use of Bt crops for a variety of reasons including:

* Bt crops pose may pose serious long term risks to butterflies such as Monarchs and the endangered Karner Blue. Monarchs in states such as Minnesota and Iowa are exposed to Bt corn pollen right at the time of their peak migration to Mexico. Insufficient scientific studies have been carried out to show that Bt corn doesn’t pose a threat to endangered butterflies like the Karner Blue.

* Bt crops may cause allergic reactions. While the EPA no longer permits pesticidal StarLink corn to be grown due to concerns about its allergenic potential, the Agency has refused to subject other Bt corn varieties to similar scrutiny. This is especially important in light of an EPA-sponsored study which detected antibodies consistent with allergic reactions in farmworkers exposed to Bt sprays.

* Bt crops can contaminate organic and conventional crops. Organic and conventional corn farmers have lost valuable markets because some of their crops were contaminated with genetically engineered corn. Contamination occurs when genetically engineered corn pollen, often carried for miles by the wind, pollinates regular corn. The EPA’s analysis has not considered the significant economic impacts of Bt corn on organic farmers and conventional farmers who don’t plant genetically engineered crops.

* Widespread use of Bt crops can lead to loss of Bt spray as an effective pest management tool. For more than 50 years, conventional and organic farmers have used Bt in spray form to control insect pests. Toxins in Bt sprays break down rapidly in the environment and do not persist in water or accumulate in the food chain. Now, because of widespread use of Bt crops in which the Bt does not break down and there is increased insect exposure to the toxin, insect resistance could develop and this valuable pest management tool could be lost.

Genetically Engineered Food Alert urges you to tell EPA to end the registrations of Bt crops in the United States. EPA must receive your comments by August 31, 2001.
