An environmental study has found that some bottles of wine from France are contaminated with pesticides. The survey analysed 40 bottles of wine and found that 34 bottles contained pesticides, some of which are classified by the EU as health threatening. Among the affected wines were three Bordeaux cru classé wines and a Burgundy Santenay. On average the bottles tested contained more than four different pesticides but they were found to exceed EU pesticide limits.
