Pregnant and older Americans shouldn't eat deli meat amid deadly listeria outbreak, CDC says

Some people should not eat any meat or cheese from any deli counters due to an ongoing outbreak of listeria in the U.S. that has killed one person, sickened more than a dozen others and caused a lost pregnancy, federal health officials say.

"You are at higher risk for severe listeria illness if you are pregnant, aged 65 or older, or have a weakened immune system due to to certain medical conditions or treatments," the U.S. Centers for Disease Control and Prevention said Wednesday in an alert posted on the agency's website.

"If you are in any of these groups, do not eat meat or cheese from any deli counter, unless it is reheated to an internal temperature of 165°F or until steaming hot."
