Blue Bell Creameries voluntarily recalled all of its products in April, including ice cream, frozen yogurt, sherbet and frozen snacks.

ATLANTA — The Centers for Disease Control and Prevention on June 10 said it had ended its investigation of a Listeriosis outbreak that affected a reported 10 people, including 3 who died. The investigation indicated various Blue Bell brand products were the source of the outbreak.

“This outbreak investigation is over,” the Atlanta-based C.D.C. said. “However, people could continue to get sick because recalled products may still be in people’s freezers, and consumers unaware of the recalls could eat them. Institutions should not serve and retailers should not sell recalled products.”

Blue Bell Creameries, Brenham, Texas, on April 20 voluntarily recalled all of its products, including ice cream, frozen yogurt, sherbet and frozen snacks, on the market made at all of its facilities. Blue Bell Creameries on June 9 said it had provided the Food and Drug Administration a detailed list of corrective actions that are under way in response to the agency’s inspection reports of Blue Bell’s production facilities in Brenham; Broken Arrow, Okla.; and Sylacauga, Ala.

“We hope our efforts demonstrate the seriousness with which we are taking this situation, as well as our commitment to making sure we get this right,” said Paul Kruse, president and chief executive officer of Blue Bell. “We are committed to seeing this plan through and to working with the F.D.A. each step of the way.

“Once Blue Bell, the F.D.A. and the applicable state regulators agree we are ready to reintroduce products into commerce, we plan to resume production with a phased-in selection of flavors and sizes, expanding only after our revised programs have demonstrated they are capable of ensuring product safety.”
