This is a story on how genetically engineered rice has contaminated
shipments of rice to countries that don't allow GE rice.
It shows that industry is failing to maintain the safety and security of its
experiments. And it is also a sludge issue.
Many university biosafety staff are unaware that the material sent to the
sewers can end up in home gardens and farmfields.
If laboratories are putting their experiments down the drain, who knows what
impact that has at the sewage plant and at the farm field?

On August 18, Agriculture Secretary Mike Johanns announced that commercial
long grain rice contained trace amounts of an unapproved, genetically
engineered (GE) rice called LL601. The government became aware of the
contamination after Bayer CropScience notified the US Department of
Agriculture and the US Food and Drug Administration in July.
Federal agencies characterized the contamination as minor - equivalent to
six rice grains out of 10,000 - and one that posed no health risk. Yet US
rice growers, who export half of their rice, watched overseas customers
quickly raise trade barriers. Bayer soon found itself a defendant in three
class action lawsuits filed on behalf of rice growers in Arkansas,
California, Louisiana, Mississippi, Missouri, and Texas.
Fallout from the LL601 contamination appeared before the end of August.
During September, the LL601 controversy gained steam.
LL601 Makes Serial Appearances
Aventis CropScience, a company bought by Bayer in 2002, developed GE plants
that synthesize the phosphinothricin-N-acetyltransferase (PAT) protein. The
PAT protein confers tolerance to glufosinate-ammonium herbicide. LLRICE62
and LLRICE06, two lines of PAT-producing GE rice, have been deregulated in
the US; they have been deemed safe for use in food and safe in the
environment. These lines have not been commercialized.
Under USDA permits, farmers and researchers performed field trials of
Aventis' LL601 rice between 1998 and 2001. Development ceased in 2001. The
LL601 story should have ended then.
In July 2006, Bayer notified the USDA and FDA about the reappearance of
LL601. USDA officials reported in August that LL601 had been found in
samples taken from storage bins in Arkansas and Missouri. By the time that
Johanns made his August 18 announcement, the FDA had concluded that the
presence of LL601 in the food and feed supply poses no safety concerns,
while the USDA's Animal and Plant Health Inspection Service had decided that
the GE rice should not create a threat to the environment.
These assurances did not help US rice farmers. Officials in Japan and Norway
immediately suspended imports of US long grain rice. The European Union, one
of US rice growers' biggest customers, quickly adopted a costly screening
procedure. Now, an accredited laboratory would have to certify a US shipment
of long grain rice as free of LL601 before it could enter the market. The EU
Commission also required Member States to randomly test products already on
the market.
Dr. Andrew Wadge, the United Kingdom's Food Standards Agency Director of
Food Safety, explained that "The presence of this GM material in rice on
sale in the UK is illegal under European health law, even at extremely low
levels. This is why we are taking steps to test American long grain rice and
ensure future imports are GM free."
According to the UK Food Standards Agency, screening procedures would remain
in place for at least six months. This measure would add to the cost of all
long grain rice varieties at a time when the market price of US rice dropped
about ten percent.
Trade relations between the European Union and the United States felt the
strain. The US stressed that trace amounts of LL601 posed no health risk. EU
officials complained that the US took more than two weeks to warn Europe of
the contamination after Bayer informed federal authorities. Europe needed to
set up protective measures to prevent an illegal incursion of unapproved GE
rice. Tension escalated with the finding that LL601 had already entered the
European Union, where no GE rice is allowed to be grown, sold, or marketed.
In mid-September, Greenpeace International reported trace amounts of LL601
in US parboiled long grain rice sold at Aldi Nord, one of Germany's leading
supermarket chains. The German Agriculture Ministry later confirmed the
presence of LL601 rice. The European Federation of Rice Millers found that
33 of 162 rice samples tested positive for LL601. By the end of September,
random checks performed by national authorities in food and retail supply
chains uncovered the presence of LL601 in at least nine EU countries.
A sense of control over the LL601 spread must have suffered with the
discovery that some contamination had avoided detection. In August, two
barge loads had passed through a Rotterdam port after testing negative for
LL601. Spot checks, later performed by Dutch officials, contradicted those
results.
The false negative results spurred the European Commission to announce that
it intends to take further action to strengthen the testing of US long grain
rice imports for LL601. In early October, the Commission stated that it
hoped to negotiate with US authorities a common testing protocol for US rice
exports. These efforts failed. On October 24, Member State experts endorsed
a draft Commission Decision to impose new mandatory testing. According to
the draft Decision, in addition to the certification requirement, all
consignments of US long grain rice must be sampled and tested at the point
of entry to the European Union by Member State authorities.
A Sticky Rice Dilemma
US agencies had company in finding that LL601 rice does not pose a threat.
The UK Food Standard Agency, the Canadian Food Inspection Agency, and Dutch
authorities confirmed the food safety of the rice. The European Food Safety
Authority announced that the consumption of long grain rice containing trace
levels of LL601 "is not likely to pose an imminent safety concern to humans
or animals." However, the agency accompanied this evaluation with a
disclaimer that it had insufficient data to provide a full risk assessment.
If trace amounts of GE rice do not pose a food safety threat, its presence
in the food supply does raise the question about LL601's escape. In late
September, Bayer announced that the company could not explain how LL601 came
to be present in commercial rice supplies. The storage bins that contained
the originally-discovered LL601 held rice from a 2005 crop originating from
several states.
>From 1999 to 2001, the Agricultural Center of the Louisiana State University
conducted field research on LL601 in collaboration with Aventis. Analyses of
the research station's rice revealed LL601 contamination in a 2003 sample of
Cheniere long grain rice. The affected Cheniere rice plot had been used to
grow foundation stock distributed to seed-producing farmers. Cheniere
foundation seed grown in 2005 appeared to be free of LL601. Thirteen other
varieties, currently in the LSU AgCenter's foundation seed program, also
received a clean bill of health.
How did the Cheniere contamination occur? Some have suggested that LL601
plants fertilized Cheniere plants to create a modified form of Cheniere
plant with the PAT gene. Since rice self-pollinates, the chance of
crossbreeding seems unlikely, however. Steve Linscombe, LSU AgCenter rice
breeder and regional director, said that research protocols with LL601
exceeded the USDA's requirements for isolating the GE plant from
conventional rice plants. Others speculate that grains of LL601 mixed
accidentally with Cheniere grains, and that future plantings of this stock
produced both plants. Can this explain the LL601 contamination of only 0.06%
reported by the USDA?
The role of the Cheniere contamination, if any, in contributing to the trace
amounts of LL601 reported by Bayer CropScience has yet to be determined. The
cause of the LL601 contamination remains unknown. The only certainty is that
LL601's surprise reappearance has cast doubt over whether the agbiotech
industry can control its engineered products.
