Consumers usually find out pretty quickly if the meat they're planning to throw on the grill has been recalled. What consumers may not be finding out about recalls and the inspection process, however, could make them doubt the effectiveness of what is actually a pretty good system to keep food safe, according to Kansas State University researchers.

Bremerhaven, July 20th 2009. Scientists from the Alfred Wegener Institute have researched the geology of the seabed in the Labrador Sea on board of the research vessel Maria S. Merian. They have studied the so-called Eirik Drift at the southern tip of Greenland, a structure of several hundred kilometres length formed like a ridge.
