HOUSTON (AP) - Blue Bell Creameries is reassuring customers that its ice cream is safe, even as it tries to determine if listeria has once again been found at one of its facilities.

The Texas company is returning products to stores following contamination last year that was linked to three deaths and prompted a national recall.

But the company announced Friday that the bacteria may have been detected at one of its plants, though it didn't say which plant. The company has three plants, in Texas, Alabama and Oklahoma.

In April, Blue Bell recalled its products after its ice cream was linked to 10 listeria cases, including three deaths in Kansas. Listeria bacteria can cause serious illness, especially in older adults, pregnant women and people with weakened immune systems.
