"People are so confident that somebody in their government is watching out for their family, and the honest answer is they are not," said U.S. Sen. Dick Durbin, D-Illinois.

Durbin reviewed surveillance video of tainted transports that included pork thawing and dripping on to fresh produce.

"Even one truckload of meat that is not carefully watched can become a lot problems for a lot families," Durbin said. "The bottom line is, no one is accepting responsibility."
