Example of Data Submitted to Federal Agencies

[Front page and table of contents]

The committee had the opportunity to review scientific studies that reflect the type of data submitted by Monsanto to EPA in support of registration for Bt Corn, Bollgard Cotton, and NatureMark NewLeaf Potato. The amount of data can be extensive (studies are typically 20 to 150 pages, single spaced, typed, 1" margins, 12 pt font), and as such, the committee did not have the time to thoroughly analyze all of the data provided. Although the specific studies may change depending on the transgenes and the plant species, the following list gives an indication of the type of data typically submitted for some transgenic pest-protected plants containing Bt transgenes.
