Two beef producers, one in California and the other in Pennsylvania, have recalled a total of close to 400,000 pounds of beef stemming from fears of E. coli contamination.

A Pennsylvania beef company is recalling about 259,230 lbs of beef products and a California company is recalling about 107,943 pounds of frozen ground beef products due to possible contamination with E. coli O157:H7, the U.S. Agriculture Department said on Friday.
