The U.S. Department of Agriculture has withdrawn its inspectors and suspended operations at a California meat company because of "insanitary conditions at the establishment," the department's Food Safety and Inspection Service said Wednesday.

The Central Valley Meat Co. in Hanford, California, supplies beef for federal school nutrition programs. In 2011, it provided nearly 21 million pounds of beef, or nearly 16% of the supply.

"The plant's suspension will be lifted once we receive adequate assurances of corrective action," a USDA statement said.

Meanwhile, Nestlé USA has issued a recall of two varieties of Philly Steak and Cheese Hot Pockets because they may contain meat the department has already recalled.

The two brands are Hot Pockets brand Philly Steak and Cheese in three different pack sizes, and Hot Pockets brand Croissant Crust Philly Steak and Cheese in the two-pack box.
