Nebraska Crop Contamination Issue Briefing

From: Tom Zinnen
Date: Thu Nov 14, 2002 2:12:36 PM US/Central
To UWEX Colleagues,
Here's the USDA press release issued yesterday (Nov 13) on the case of soybean seeds being impounded in Nebraska.
This press release also addresses the issue of another earlier violation, one in Iowa, of procedures for running test plots of transgenic plants. Three links to articles on the Des Moines Register website at the bottom of this page have something about that.
What the USDA reports did happen in Nebraska:
  1. The company ProdiGene failed to remove tasseled volunteer corn plants from a field of soybeans, soybeans growing on the site that in summer 2001 was a test plot of corn genetically engineered to make a drug.

  2. That failure to remove the volunteer corn before it tasseled and to remove the tasseled corn before the soybeans were harvested are violations of the regulations of such test plots.

  3. The failure to remove the tasseled corn before harvesting the soybeans resulted in the soybeans being considered to be adulterated.

  4. Furthermore, the 500 bushels of adulterated soybeans were delivered to an elevator and mixed with other soybeans, and that adulterated a total of 500,000 bushels.
Some comments:
  1. So far, it is not clear to me if the volunteer corn was transgenic or if the corn produced seed. The USDA press release says the volunteer corn did not produce viable seed. That leaves open the possibility of nonviable corn seed mixed in the soybean seeds. However, even if corn seed was not in the soybean seed, the failure to remove the tasseled corn was a violation of regulations.

  2. A food, including a crop, can be adulterated by at least two ways: one is because it contains something that is prohibited. The other is because it is processed in a way that is prohibited. So far this case is a case of the latter: a violation of procedure, and that suffices.

  3. There is no claim that the gene for the drug moved from corn to soybean.

  4. To reduce the possibility of the spread of a gene for a drug from one variety of corn to other varieties of corn, plant breeders can put the gene for the drug into a line of corn that produces little if any viable pollen. It is not clear to me whether Prodigene uses this approach.

  5. This case in Nebraska illustrates the legal if not the food safety problems and environmental problems of the strategy of using plants that are usually food crops to make non-food-grade-quality drugs or enzymes or industrial feedstocks. Such drug-producing varieties are not fungible--that is, they are not interchangeable for varieties that produce food-grade corn.

USDA INVESTIGATES BIOTECH COMPANY FOR POSSIBLE PERMIT VIOLATIONS

       WASHINGTON, Nov. 13, 2002--The U.S. Department of Agriculture's Animal and Plant Health Inspection Service, in close coordination with the Food and Drug Administration is investigating ProdiGene, Inc., of College Station, Texas, for violations of the Plant Protection Act.

       During a compliance inspection in October 2002, APHIS found potential permit violations by ProdiGene at a site in Nebraska that had been used for small-scale field testing of genetically engineered corn in 2001.  APHIS discovered tasseled volunteer corn plants growing in a soybean field that stands on the site of the 2001 field test.  The presence of these plants is a violation of permit conditions. Following this discovery, APHIS instructed ProdiGene to remove the volunteer corn plants from the field, despite the fact that the corn plants did not have viable seed.  However, the soybeans were harvested before all of the tasseled corn was removed.  APHIS immediately placed a hold on the soybeans that were located at a single storage facility in Nebraska so that these materials would not enter the human or animal food chains.

       APHIS also discovered possible permit violations at a ProdiGene 2001 test site in Iowa in September 2002.  Volunteer tasseled corn plants were found growing in a soybean field and in a pile of volunteer corn plants removed from the field earlier in the season--both of which did not comply with permit conditions.  At APHIS' request, and under APHIS supervision, ProdiGene has harvested and destroyed by incineration 155 acres of corn surrounding the field test site.

       At the conclusion of the ongoing investigation into ProdiGene's regulatory permit compliance APHIS, in coordination with the FDA, will determine the appropriate enforcement action against ProdiGene.

       Under the Federal Plant Protection Act, APHIS regulates the movement, importation and field release of genetically engineered plants.  APHIS requires significant safeguards to prevent the unauthorized release of genetically engineered material.  The Act provides criminal penalties for knowing violations as well as civil penalties.  Any company or individual that violates the Act faces civil penalties of up to $250,000 per violation, or $500,000 per adjudication, and may have their permits revoked.

       USDA has strengthened field-testing requirements for permits on genetically engineered traits that are not intended for commodity uses, such as pharmaceuticals, veterinary biologics and certain industrial products by adding new safeguards as a condition for all permits allowing the confined release of such products into the environment.  These specific safeguards include comprehensive confinement procedures, performance standards, and required monitoring/auditing practices for ensuring that out-crossing or commingling with other seeds and commodities are prevented.
