Oregon Salmonella cases linked to Cold Stone Creamery ice cream

 


 

A new outbreak of salmonellosis has been traced to consumption of Cold Stone Creamery ice cream, public health officials in the Oregon Department of Human Services (DHS) said today.

 

Cold Stone announced a national recall of "cake batter" flavor ice cream today, after the Minnesota Department of Health linked cases of Salmonella Typhimurium in that state to consumption of that flavor.

 

As of today, Oregon public health officials have identified four salmonellosis cases that appear to be part of this cluster, in Linn, Lane and Washington counties.

 

Other cases have been identified in Washington and Ohio and the number of Oregon and national cases is expected to increase.

 

Kohn said there are at least 20 Cold Stone Creameries in Oregon. This brand of ice cream is not sold at any other retail outlets, such as grocery stores or supermarkets. Cake batter ice cream is also sold as part of the "Birthday Cake Remix," according to Cold Stone officials.

 

"Anyone who has Cold Stone brand cake batter flavor or Birthday Cake Remix ice cream in their freezer should discard it immediately," said Kohn. "We are working with other state health departments, federal authorities, and the manufacturer to identify other cases and to determine how the contamination occurred. Cold Stone officials are being very cooperative with our investigation."

 

Salmonellosis is an acute bacterial infection that can cause diarrhea--sometimes bloody--fever, and vomiting. Symptoms usually develop within one to six days after eating contaminated food. Most cases resolve without the need for medical attention.

 

Antibiotics are not recommended for persons with uncomplicated diarrheal illness, and can extend the period of communicability. The risk of severe illness is particularly high among the elderly, people with compromised immune systems, and the very young.

 

"Anyone who has eaten Cold Stone cake batter ice cream and developed severe symptoms should contact their local health department, " Kohn said. "Those who are still sick should contact their doctor for advice. Some persons with salmonellosis develop serious illness that can lead to hospitalization and even death."

 

At least one person in another state was hospitalized, Kohn said.

 

Contaminated ice cream was previously identified as the source of a 1994 salmonellosis outbreak that affected more than 200,000 people nationwide.
