Blue Bell Creameries announced late Monday that it is recalling all of its products after the Listeria bacteria was found in two samples of chocolate chip cookie dough ice cream.

The company released a statement saying that is pulling its ice cream, frozen yogurt, sherbet and other frozen treats because they might be contaminated with Listeria.

"This means Blue Bell has now had several positive tests for Listeria in different places and plants," the company said in a written statement. "At this point, we cannot say with certainty how Listeria was introduced to our facilities, and so we have taken this unprecedented step."

Altogether, federal regulators say that there has been at least 10 listeria illnesses linked to ice cream and other products made by the Blue Bell Creameries since 2010.

Back in March, three patients at a Kansas hospital died from a food-borne illness after eating Blue Bell ice cream contaminated with listeria.

"These people had been in and out of the hospital for other reasons," Sara Belfry, spokeswoman for the Kansas Department of Health and Environment, told the Los Angeles Times. "This was a contributing cause, not the only cause."

In total, five people in the state were infected with life-threatening listeriosis, which is caused by eating food tainted with the bacteria Listeria monocytogenes. Symptoms include fever, muscle aches and diarrhea. However, the disease is treatable with antibiotics.

According to the Centers for Disease Control and Prevention (CDC), four of the victims drank milkshakes last month made with a single serving of Blue Bell's Scoops ice cream at the hospital, a finding "that strongly suggests their infections were acquired in the hospital," reports Fox News. The CDC added that all of the individuals were being treated in the same hospital for unrelated conditions.

The Food and Drug Administration (FDA) stated that the outbreak was linked to tainted products made on a production line at the Blue Bell Creameries plant in Brenham, Texas.
