The true number of sick people in an outbreak is likely higher than the number reported, and the outbreak may not be limited to the states with known illnesses. Often people recover without medical care and are not tested for Listeria.

Of the 23 people interviewed and asked about the foods they ate prior to becoming ill, all reported eating ice cream, and 16 reported eating Big Olaf Creamery brand ice cream or eating ice cream at locations that have been supplied by Big Olaf Creamery. Four illness clusters were identified in this outbreak. An illness cluster is defined as two or more people who do not live in the same household who report eating food from the same retail location before getting sick. If several unrelated sick people ate food from the same retail location, it suggests that the contaminated food item was served or sold there. Ten people were identified as being part of four illness clusters and all clusters were linked to retail locations that sold Big Olaf Creamery ice cream.

Investigators used the PulseNet system to identify illnesses that might be part of this outbreak. CDC PulseNet manages a national database of DNA fingerprints of bacteria that cause foodborne illnesses. DNA fingerprinting is performed on bacteria using a method called whole genome sequencing (WGS).

WGS showed that bacteria from sick people’s samples are closely related genetically. This means that people in this outbreak got sick from the same food, Big Olaf Ice Cream.

The Florida Department of Agriculture and Consumer Services (FDACS) collected samples of ice cream and environmental samples from the ice cream production area at the Big Olaf Creamery facility in Sarasota, Florida. FDACS also performed WGS on these samples, and the Florida Department of Health identified the outbreak strain in the samples collected from the ice cream and the environment.

On July 2, 2022, CDC advised people who had Big Olaf Creamery ice cream at home to throw away any remaining product. On July 13, 2022, Big Olaf Creamery LLC recalled all flavors, lots, and expiration dates of Big Olaf brand ice cream through June 30, 2022.

Listeriosis is a serious infection caused by eating food contaminated with the bacterium Listeria monocytogenes. Listeria has been found in a variety of raw foods, such as uncooked meats and unpasteurized (raw) milk products. Listeria is killed by heating, but contrary to many other bacteria it thrives in the cool temperatures such as those provided by refrigeration. Therefore Listeria may be found on ready-to-eat foods such as cheese, hot dogs, deli meats, or produce.

Symptoms of Listeria Infection

Listeria has an incubation period of 21-70 days, so a person with an infection may not realize it for sometime after eating a contaminated food. When symptoms develop they typically manifest themselves in the form of fever, muscle aches, and sometimes diarrhea or nausea.

A Listeria infection may spread to the nervous system which may cause headache, stiff neck, loss of balance, or convulsions. In some cases Listeria may infect the central nervous system causing meningitis and/or brain infection.

If a pregnant woman becomes infected, miscarriage, sillbirth, or infection of the newborn can occur.
