Link between listeria, second poultry plant puzzling

PHILADELPHIA (AP) -- Investigators who had traced a nationwide outbreak of food poisoning to a Pennsylvania factory have discovered the same strain of potentially deadly bacteria at a poultry plant 30 miles away in New Jersey.

The national Centers for Disease Control said last month that a Wampler Foods plant in Franconia was responsible for a listeria outbreak that killed seven people and sickened 50.

But Friday, a batch of listeria genetically indistinguishable from that found at the Wampler plant turned up in a sample of deli meat at J.L. Foods in Camden, N.J., the CDC said.
