Health officials said Friday that an outbreak at the center near Portland killed one child and sickened three others.
The four children were hospitalized, and Elizabeth Winter of the Washington state Department of Early Learning said her department was notified Friday that one of them, a 4-year-old boy, had died.
The other three others have been released, said Dr. Alan Melnick, health officer with the Clark County, Wash., health department. He declined to provide any further details on the child who died.
Melnick said the department learned of the first hospitalization involving the E. coli O157:H7 bacteria strain on March 19.
Health officials determined that the business' hygienic practices were acceptable, but closed it down in April 2 when it became apparent that E. coli was spreading from person to person, Melnick said in an interview with Portland's KGW-TV.
"We believe we have it confined," Melnick told reporters Friday.
Fletch day care operated by Dianne and Larry Fletch is housed in a tidy single-story yellow rambler on a large lot set back from the road, surrounded by a 6-foot-tall chain link fence. Winter said it has operated since 1990 and no complaints have been filed against it. Lately, it has been caring for about 22 children.
"This is a very difficult time for the family who has suffered such an incredible loss," the Fletches said in a statement Friday. "It is also a difficult time for our day care families and the children who were his friends. It is an especially difficult time for us as day care providers."
The statement said the day care has worked closely with the health department to put measures in place to control the spread of the illness.
The Fletches did not immediately return phone messages from The Associated Press seeking additional comment.
