In Germany, at least ten people have now died and three hundred have been taken ill after contracting a rare and virulent form of E.coli blamed on contaminated cucumbers. The outbreak in Hamburg is the is the largest ever in Germany and the biggest of its kind worldwide.
Health officials say traces of the bacterium have been found on a shipment of cucumbers from Spain.
A spokesman for the EU says two greenhouses in Spain identified as the source of the outbreak have suspended production.
Water and soil from the site are being analysed to see if the contamination originated there or elsewhere. The results are expected later this week.
A small number of cases have also been reported in the UK, Sweden, Denmark and the Netherlands. All have connections to travel from Germany.
