Bid to identify E.coli source

Researchers have still not been able to pinpoint the cause of a food-borne bacterial outbreak that has hit Germany and other European countries, Germany’s health minister said today.

Ilse Aigner told German ARD Television that scientists are working non-stop to try to find out what produce has caused the contamination with an unusual strain of the common E.coli bug which has killed 15 people and infected about 1,500 in Europe.
