The Milwaukee Channel has also reported on E. coli linked to the Sam’s club recall.
From the article:

The investigation into the how the meat was contaminated and how far it has spread was just beginning, said Dr. Harry Hull, Minnesota state epidemiologist.
“There is the potential for this to be much larger,” he said.
John Schaller, vice president of operations for Carneco, said Sam’s Club notified his company about the illnesses on Aug. 2.
“But the problem is that anyone can put this in their freezer and eat it six months from now,” Schaller said.
