(ANSA) - Parma, October 14 - As many as 30,000 internationally prized Italian prosciutti from the Parma region have been swept away in the dirty flood water that is also threatening crops as it washes through the Emilia-Romagna region, farm group Coldiretti said Tuesday. Stables have been flooded and planting of maize has been threatened by the flood waters that have hit the provinces of Parma and Piacenza, where as much rain fell in a few hours as is normal for three months, the group added. The flooding around Parma came at the same time as torrents have spewed mud throughout the medieval port city of Genoa in nearby Liguria, killing one man and destroying millions of euros in property.
