No answers yet as to source of E.coli scare

Health officials in Germany are still searching for the source of the E.coli outbreak which has killed 23 people in Europe.

With the latest chief suspect being beansprouts from a farm in Lower Saxony, tests are continuing. Although 23 of 40 samples have registered negative this doesn't mean some beans weren't contaminated before they sprouted and were then later distributed.

But Germany's agriculture minister is still warning against eating other salad based vegetables.
