Listeriosis

Listeriosis info
   Listeriosis home
On this page Listeriosis is an often serious infection caused by eating food contaminated with the bacterium Listeria monocytogenes. The disease affects primarily pregnant women, newborns, and adults with weakened immune systems. It can occur sporadically, or in foodborne outbreaks of septicemia (blood poisoning), gastrointestinal (GI) illness, or a combination of both.

In four reported outbreaks of GI listeriosis, the syptom profile was 72% fever, 68% diarrhea, 56 myalgia (muscle ache), 55% headache, 55% abdominal (stomach or intestinal) cramping, 41% nausea and 35% vomiting. A point-source outbreak of GI listeriosis has not occurred in Oregon—yet.
