The parents of a Lincoln County girl, Serena Profitt, who died last month of shiga-toxin producing E. coli, say public health officials suspect the 4-year-old was infected by droppings from the family’s goat.

But Rachel Profitt told The Oregonian lab tests have not been conclusive and the investigation continues into the death of her daughter Serena.

Proffit says Lincoln County health officials advised the family to euthanize the goat, a family pet named Cathy. They are reluctant. It’s now corralled away from people.

A 5-year-old boy and a 3-year-old girl from surroundings areas have also been infected and developed hemolytic uremic syndrome.

Health officials say they’re still investigating the cause of the three kids’ E. coli infections.
