LINCOLN, Neb. (AP) -- Nebraska's homeland security director says state officials are increasingly focused on computer hackers and terrorism aimed at agriculture as potential threats.

Lt. Gov. Rick Sheehy said Wednesday that officials plan to devote more attention to both issues at an infrastructure protection conference later this month.

Nebraska homeland security officials will meet with representatives from the FBI, U.S. Attorney's office and private industries at the meeting in LaVista. The conference is designed to help state and local governments, nonprofit agencies and businesses prepare for large-scale emergencies.

Sheehy says the gathering will look at monitoring to detect any attempts to infect livestock with diseases and contaminate food supplies.
