CDC is currently investigating a multistate outbreak of Listeria monocytogenes infections. Up to August 24th, there were 24 people reported sick from 13 states (CA, FL, IA, IL, IN, KS, KY, MI, MO, NY, OH, OR, and TX). 22 people have been hospitalized and two deaths have been reported.
CDC advises that this is an ongoing investigation and no specific food item, grocery store, or restaurant chain has been identified as the source of the infections.
As noted by the CDC, pregnant women, 65 or older adults, and people with weakened immune systems are more likely to get Listeria infections. Usually, for pregnant women, the symptoms include only fever and other flu-like symptoms, such as fatigue and muscle aches. For people other than pregnant women, the symptoms may include headache, stiff neck, confusion, loss of balance, and convulsions in addition to fever and muscle aches.
