( CNN ) Blue Bell ice cream has temporarily shut down one of its manufacturing plants over the discovery of listeria contamination in a serving of ice cream originating from that plant . Public health officials warned consumers Friday not to eat any Blue Bell-branded products made at the company 's Broken Arrow , Oklahoma , plant . That includes 3-ounce servings of Blue Bell ice cream from this plant that went to institutions in containers marked with the letters O , P , Q , R , S or T behind the coding date . The warning by the Centers for Disease Control and Prevention does not affect other Blue Bell ice cream , including other 3-ounce servings , not made at the plant . But Blue Bell has recalled other products . The company is shutting down the Broken Arrow facility `` out of an abundance of caution '' to search for a possible cause of contamination . It is the third time Blue Bell has taken action in light of a listeria outbreak at a Kansas hospital that served the company 's ice cream . Listeria monocytogenes was recently found in a cup of ice cream recovered from the hospital . The cup contaminated with the bacteria was produced at the Broken Arrow plant in April 2014 , Blue Bell said . And , according to the CDC , listeria bacteria was found in additional samples of the same product that were recovered from the plant . The bacteria in the hospital sample and the factory sample appeared to match each other genetically , the CDC said . But they did not appear identical to listeria samples taken from patients infected in the Kansas outbreak . In a separate outbreak in Texas , the CDC did find that listeria samples taken from patients who came down with listeriosis between 2010 and 2014 in a hospital that served 3-ounce Blue Bell cups matched the listeria in recovered samples . None of this means the ice cream is the source of either spate of the infections . `` Investigation to determine whether these illnesses are related to exposure to Blue Bell products is ongoing , '' the CDC said . In early March , in light of the Kansas listeria outbreak , Blue Bell recalled a group of products made at a plant in Texas . It later added 3-ounce cup servings to the recall . Five people were infected and three died in the past year in Kansas from listeria that might be linked to Blue Bell Creameries products , according to the CDC . All five of them were hospitalized at the same hospital before developing listeriosis , the CDC said . At least four of them had consumed milkshakes made with Blue Bell ice cream before developing the infection . `` We are devastated and know that Blue Bell has to be and can be better than this , '' Paul Kruse , Blue Bell CEO and president , said in a statement . `` Quality and safety have always been our top priorities . We are deeply saddened and concerned for all those who have been affected . '' The CDC advises that individuals and institutions should check their freezers for the recalled products and throw them away . In a statement on its website , Blue Bell said `` this recall in no way includes Blue Bell ice cream half gallons , pints , quarts , 3 gallons or other 3 oz . cups . '' This has been the first product recall in the 108-year history of Blue Bell Creameries , the company said . Listeriosis is a serious infection caused by eating food contaminated with listeria , and primarily affects the elderly , pregnant women , newborns and people with weakened immune systems , according to the CDC . Symptoms of a listeria infection are fever and muscle aches , sometimes associated with diarrhea or other gastrointestinal symptoms . In the United States , an estimated 1,600 people become seriously ill each year , and approximately 16 % of these illnesses result in death . Cervical infections caused by listeriosis in pregnant women may result in stillbirth or spontaneous abortion during the second or third trimesters . CNN 's Debra Goldschmidt , Amanda Watts and Jacque Wilson contributed to this report .
