Scientists Miguel Sanchez of ChileBio and Wayne Parrott of the University of
Georgia released an article on their review of research papers that are
usually used as evidence of negative effects of GM food and feed. Their
review article is published in the Plant Biotechnology Journal.

A total of 35 articles were evaluated. These articles are often cited by
biotech critics to emphasize the adverse effects of GM crops. Studies not
published in scientific journals as well as those reports evaluating only
immunogenicity of pure proteins, instead of whole food or GM crops studies,
were not included in the evaluation. Most of the articles assessed (43%)
were about the effects of herbicide tolerant soybean event 40-3-2. Insect
resistant maize MON810 was covered by 23%, while 9% tackled non-commercial
events. Seven studies (20%) did not disclose which particular GM crop was
used, making it impossible to replicate the experiments. Eleven out of 35
studies were authored by the Malatesta group at the University of Urbino and
University of Verona in Italy.

The evaluation of research articles showed that the studies were conducted
in just a few laboratories and published in less popular journals.
Methodological flaws were also found in the papers, such as failure to
disclose important details in the experiment and actual measurement of
results, which invalidate the conclusions of the study.
