From the windows of their whitewashed school, Preignac's 300 nursery and primary pupils look over the verdant vineyards of Sauternes.
The grapes are ripe and will soon be turned into the most acclaimed sweet white wines in the world.
Yet the price for keeping the fabled grapes in good health may have been the pupils' lives. Preignac, population 2200, has a child cancer rate five times the French national average and a new report says scientists cannot "exclude" the possibility of a link to pesticides sprayed on the vines.
In December 2012, Jean-Pierre Manceau, Preignac's former mayor and a researcher at the CNRS national science research centre, alerted authorities to the cancer rate.
After reports highlighting the dangers of pesticides, France's national health monitoring institute, InSV, and the regional health agency, ASR, ordered a study on cancer cases among local children in 2013.
