Summary

A safety assessment found that residues of the herbicide 2,4-D and its metabolite 2,4-dichlorophenol (2,4-DCP) in genetically modified (GM) soybeans are unlikely to pose a risk to consumers. Analytical methods are available to enforce the maximum residue level (MRL).

Area of Science:

Agricultural Science
Food Safety
Environmental Chemistry

Background:

Dow AgroSciences requested an import tolerance for 2,4-D in GM soybeans.
GM soybeans exhibit tolerance to the herbicide 2,4-D.
Soybeans are imported from Canada and the USA into Greece.

Purpose of the Study:

To evaluate the safety of 2,4-D residues in GM soybeans.
To establish an import tolerance for 2,4-D in GM soybeans.

Main Methods:

Residue analysis of 2,4-D and its metabolite 2,4-dichlorophenol (2,4-DCP) in GM soybeans.
Assessment of consumer risk based on submitted data.
Evaluation of analytical method validation for enforcement.

Main Results:

Residues of 2,4-D and 2,4-DCP were detected in GM soybeans treated with 2,4-D.
The risk to consumers from these residues is considered unlikely.
Validated analytical methods exist for enforcing the proposed maximum residue level (MRL).

Conclusions:

The proposed import tolerance for 2,4-D in GM soybeans is supported by safety data.
Enforcement of the MRL for 2,4-D in soybeans is feasible with available methods.
