The University of Minnesota’s National Center for Food Protection and Defense has been awarded a $20 million grant from the U.S. Department of Homeland Security.

The center is a multi-disciplinary group that works on addressing potentially catastrophic threats of intentional contamination of the nation’s food supply.

The university says in a news release that it expects the center to receive the money over six years. It has been funded by Homeland Security in the past.

The center was launched in 2004 and has found ways to close vulnerabilities within the agriculture system and devised methods to recover from widespread contamination.
