Outbreak first announced December 18, 2014.

As of December 30, 2014, a total of 32 people infected with the outbreak strains of Listeria monocytogenes have been reported from 11 states: Arizona (4), California (2), Minnesota (4), Missouri (5), Nevada (1), New Mexico (6), North Carolina (1), Texas (4), Utah (1), Washington (1), and Wisconsin (3). Dates when the Listeria strains were isolated range from October 17, 2014, to December 11, 2014. Ten illnesses have been associated with a pregnancy (occurred in a pregnant woman or her newborn infant). One fetal loss has been reported. Among people whose illnesses were not associated with a pregnancy, ages ranged from 7 to 92 years, with a median age of 66 years, and 32% were female. Three invasive illnesses (meningitis) occurred among otherwise healthy children aged 5–15 years. Thirty-one ill people have been hospitalized and six deaths have been reported. Listeriosis contributed to three of these deaths, and it is unclear whether it contributed to an additional two deaths. The sixth death was unrelated to listeriosis.

Illnesses that started after December 14, 2014, might not be reported yet due to the time it takes between when a person becomes ill and when the illness is reported.

Although voluntary recalls have been issued for three brands of commercially produced, prepackaged caramel apples, CDC’s Advice to Consumers remains the same. CDC continues to recommend that U.S. consumers not eat any commercially produced, prepackaged caramel apples, including plain caramel apples as well as those containing nuts, sprinkles, chocolate, or other toppings, until more specific guidance can be provided.
