Cryptosporidiosis Associated with Consumption of Unpasteurized Goat Milk — Idaho, 2014

On August 27, 2014, the Idaho Department of Health and Welfare's Division of Public Health (DPH) was notified of two cases of cryptosporidiosis in siblings aged <3 years. Idaho's Southwest District Health (SWDH) investigated and found that both children had consumed raw (unpasteurized) goat milk produced at a dairy licensed by the Idaho State Department of Agriculture (ISDA) and purchased at a retail store. Milk produced before August 18, the date of illness onset, was unavailable for testing from retail stores, the household, or the dairy. Samples of raw goat milk produced on August 18, 21, 25, and 28, taken from one opened container from the siblings' household, one unopened container from the retailer, and two unopened containers from the dairy, all tested positive for Cryptosporidium by real-time polymerase chain reaction (PCR) at a commercial laboratory. On August 30, ISDA placed a hold order on all raw milk sales from the producer. ISDA and SWDH issued press releases advising persons not to consume the raw milk; SWDH issued a medical alert, and Idaho's Central District Health Department issued an advisory to health care providers about the outbreak.
