According to the Centers for Disease Control and Prevention (CDC), listeriosis caused by food-borne listeria monocytogen bacteria affects approximately 1,600 people each year, of which approximately 260 die. The highest risks are pregnant women, newborns, young children, children over 65 years old, and people with a weakened immune system. In pregnant women, Listeria infection can cause miscarriage, stillbirth, or premature birth.
Symptoms of Listeria infection include fever and diarrhea, along with headaches, stiff neck, nausea, loss of balance, abdominal pain, confusion and cramps, according to the CDC and FDA. However, pregnant women usually have milder symptoms, the CDC says.
Western United Fish Company said there were no diseases related to the recalled AHI tuna products as of Saturday.
