Story highlights CRF Frozen Foods expanded voluntary recall due to possible listeria risk

Seven people have become ill and were hospitalized due to listeria

(CNN) CRF Frozen Foods announced Tuesday that it's expanding a voluntary recall of frozen organic and non-organic fruits and vegetables because of possible health risks.

The company issued the recall in cooperation with the U.S. Food and Drug Administration and the Centers for Disease Control and Prevention because the products might be contaminated with listeria.

Listeria is a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes. It can cause serious, sometimes fatal infections in older adults, pregnant women, newborns and individuals with weakened immune systems, according to the CDC. Symptoms include high fever, severe headache, stiffness, nausea, stomach pain and diarrhea.

CRF said the CDC notified it that seven people from three states have become ill and were hospitalized due to listeria. Some of these illnesses have been linked to consuming CRF-manufactured or processed products. Two of these individuals died, but listeria was not the cause of death in either person, CRF said in a statement.

The expanded recall of frozen vegetables includes all of the frozen organic and non-organic fruit and vegetable products manufactured or processed in CRF Frozen Foods' Pasco, Washington, facility since May 1, 2014. All of the affected products have the best by dates or sell by dates between April 26, 2016 and April 26, 2018. These include about 358 consumer products sold under 42 different brands.
