(ANSA-AFP) - ATHENS, SEP 15 - A quarter of Greece's annual agricultural production was wiped out in last week's deadly flash floods triggered by Storm Daniel, which drenched the central region of Thessaly, according to experts. The floods, which killed 15 people, have also left thousands of people in temporary shelters in hotels, schools or with relatives while 30 villages were inaccessible amid the threat of waterborne diseases. Officials were trying to determine if a body found on a beach in Pelion, central Greece, was that of an Austrian missing with his wife since last week. As government officials began the daunting task of mapping the damage dealt to the plain that feeds much of Greece, one pressing need was to dispose of tens of thousands of decomposing farm animals. Out of over 110,000 dead sheep, goats, pigs, cows and chickens reported lost by farmers, fewer than half have been buried or incinerated, officials said. Inspection crews were still unable to reach half the areas with reported dead livestock, the agriculture ministry said Wednesday. (ANSA-AFP).
