Bt Toxin Found in Blood of Pregnant Women and Fetuses

CryAb1 toxin was detected in pregnant women, their fetuses and non-pregnant women. This is the first study to reveal the presence of circulating [pesticides associated to genetically modified foods] in women with and without pregnancy, paving the way for a new field in reproductive toxicology including nutrition and utero-placental toxicities.

NOTE: Bt corn (maize) was developed by transferring cry1Ab from Bacillus thuringiensis (Bt) into corn. It is to be found in the most common GM corn - Monsanto's Bt MON810 (marketed with the trade name YieldGard) - a corn genetically engineered to resist corn borers by producing its own insecticide, the Cry1Ab toxin. Global production of Bt corn takes place on many millions of hectares worldwide and many different types of foods contain Bt corn. In the European Union, seven countries - Austria, Hungary, Greece, France, Luxembourg, Germany and Bulgaria have banned Mon810.

Pesticides associated to genetically modified foods (PAGMF), are engineered to tolerate herbicides such as glyphosate (GLYP) and gluphosinate (GLUF) or insecticides such as the bacterial toxin bacillus thuringiensis (Bt).

The aim of this study was to evaluate the correlation between maternal and fetal exposure, and to determine exposure levels of GLYP and its metabolite aminomethyl phosphoric acid (AMPA), GLUF and its metabolite 3-methylphosphinicopropionic acid (3-MPPA) and Cry1Ab protein (a Bt toxin) in Eastern Townships of Quebec, Canada.
