In early 2012, routine disease surveillance detected an outbreak of campylobacteriosis in Butler County, Kansas. After conducting several interviews with ill individuals, investigators learned that all had consumed unpasteurized (raw) milk produced by a dairy located in Whitewater, Kansas. A total of 18 cases were identified - 7 laboratory confirmed cases of Campylobacter jejuni and 11 probable cases. Dates of illness onset ranged from December 15, 2011 to January 15, 2012. No one was hospitalized and no one died.

Kansas Department of Agriculture conducted an inspection of the dairy farm on February 9, 2012 and found no violations. The owner of the dairy farm voluntarily quit selling raw milk on January 17, 2012 after hearing about the reported illnesses. The inspector noted that the farm’s milking procedures met or exceeded the Food and Drug Administration’s Pasteurized Milk Ordinance regulations.
