CDC's listeria report isn't 100% sure, but it's final
WASHINGTON — After months of uncertainty, the Centers for Disease Control and Prevention (CDC) issued its final report on the Bil Mar Foods listeria outbreak with a suggested conclusion supported by the available evidence: Removing a refrigeration unit probably spread the bacteria.
“It is impossible to reconstruct the exact events that triggered this outbreak,” concedes Paul S. Mead, M.D., M.P.H., staff epidemiologist, Division of Bacterial and Mycotic Diseases for the CDC.
