CDC warns Americans about listeria outbreak Tied to pre-cooked chicken before the 4th of July festivities.
Actual numbers may be higher, as some people recover from Listeria without seeking medical help and it may take one to four weeks for symptoms to appear.
While the CDC investigates, the Agency recommends That people “reheat pre-cooked chicken to an internal temperature of 165 degrees Fahrenheit” and avoid eating “any cold dishes made with pre-cooked chicken, such as savory chicken salad and salads with chicken sold at a salad bar, deli counter, or section radiator from the store.
All of the diseases that have been linked to this outbreak have been in long-term care facilities or hospitals.
The CDC notes that “pregnant women, adults 65 or older, and people with weakened immune systems are at greater risk of developing serious illness.”
Listeria is caused by the germ Listeria monocytogenes. While it usually only leads to minor illness in pregnant women, it can be devastating to the fetus or newborn, possibly causing miscarriage, stillbirth, or premature birth.
About 1,600 Americans become infected with it each year, resulting in death in about 20% of cases, according to the CDC.
