In October 2013 three Minnesota children became ill with E. coli O157 infections after contact with animals at Dehn's Pumpkins located in Dayton, Minnesota. One child was hospitalized and developed hemolytic uremic syndrome. The children visited the farm on October 12 or October 13 and became ill on October 16 or 18. All three had contact with cattle and/or goats at Dehn's. All three were infected with an indistinguishable strain of E. coli O157:H7 as determined by PFGE.
