Three Minnesota residents have become ill with confirmed E. coli O157:H7 infections after contact with animals at Dehn’s Pumpkins in Dayton, MN, the Minnesota Department of Health reported today.

The three cases were all children, ranging in age from 15 months to 7 years and are residents of the Twin Cities metro area. One child is hospitalized with hemolytic uremic syndrome (HUS), a serious complication of an E. coli infection characterized by kidney failure. The others were not hospitalized and are recovering. Routine monitoring by the health department identified the E. coli O157:H7 cases, which all have bacterial isolates with the same DNA fingerprint. These cases visited the farm on October 12 or 13, and became ill on October 16 or 18.

The Minnesota Department of Health is in the process of following up with any groups that visited the farm in order to help determine if more people have become ill. At this time, two additional people have reported symptoms consistent with E. coli O157:H7 infection and are currently being tested. These people visited Dehn’s on October 18, raising concern that exposures also could have occurred after the weekend of October 12-13.

All of the cases reported having contact with cattle and/or goats at Dehn’s. The farm owners have been cooperating fully with the investigation and public access to the cattle and goat areas is being prohibited. The rest of the farm, including the pumpkin patch, remains open for business.
