EFSA Rejects GM Form Of Corn Used In NZ Food
Europe’s food safety regulator has rejected a form of GM corn that is legal to use in New Zealand foods. Food Standards
Australia New Zealand (FSANZ) approved the same product in 2010.
In rejecting the new GM corn, the European Food Safety Authority (EFSA) is upholding a standard set by the international
food safety guidance body known as Codex. This requires assessments of GM foods to be made with reference to the
conventional food it was derived from.
The Agency’s GMO Panel said: “In the absence of an appropriately performed comparative assessment by the applicant, the
EFSA GMO Panel was not in the position to complete its risk assessment on maize 98140 and therefore does not conclude on
the safety of maize 98140 compared with its conventional counterpart with respect to potential effects on human and
animal health.”
The key defect in the safety assessment was the use by the developer, DuPont Pioneer, of an incorrect line of maize to
use as a comparator to detect possible harms that might be caused by the GM maize. This comparator, called a negative
segregant, was found to have been another GM maize. As such, the comparator had no pre-existing history of safe use upon
which to base a claim of safety for the GM maize under consideration by the Authority.
“As negative segregants are derived from a genetically modified organism, the GMO Panel does not consider them
appropriate conventional counterparts with a history of safe use” EFSA said.
A comparative risk assessment is the most common way of assessing the safety of GM-derived foods. In this case, if it
had compared two foods that have no history of safe use, the Authority was in danger of overlooking new potential
hazards that the two GM maize lines had in common.
This is not the first GM food that FSANZ has approved as safe using the same flaw in its assessment. In perhaps the
first case of its kind, the University of Canterbury Centre for Integrated Research in Biosafety (INBI) challenged FSANZ
over this practice in its approval of high lysine corn LY038 eight years ago. FSANZ rejected the concerns of INBI at the
time. However, EFSA raised this issue with the corn’s developer, Monsanto, and as reported (Christchurch Press, 2
November 2009) Monsanto withdrew plans to grow the maize rather than address EFSA’s safety concerns.
High lysine corn and the new GM corn just rejected (98140) both remain approved for consumption by the people of
Australia and New Zealand despite other regulators being unable to determine the safety of these products. In addition,
FSANZ has approved as safe for use as food at least two other products that used the incorrect comparator: a soybean
line called DP-305423-1-1 and the amylase corn line 3272.
FSANZ Chief Scientist Dr. Paul Brent told National Radio’s Nine to Noon programme on 28 March 2013 “that all of the
regulators around the world do the GM food safety assessments in the same way we do…I’m talking about the European Food
Safety Authority that has a GM Panel.” If FSANZ is to indeed align with EFSA, as well as Codex guidelines, then it will
need to revoke the relevant approvals.
