The Minnesota Department of Health is investigating a petting zoo and farm in Dayton. In the past several weeks, three children have been infected and are recovering from E. coli infections after visiting Dehn’s Pumpkins. The kids are between the ages of 15 months and seven years. One child is still hospitalized with serious complications including kidney failure. The health department says that the E. coli bacteria are common in cattle and goats, and Dehn’s is cooperating with the investigation. The farm has closed public access to the animals.
