Baker City, OR -

The Baker City Public Works Department says recent water samples were free of cryptosporidium and a boil order has been lifted.

Health officials still recommend that people with compromised immune systems seek the advice of a health care professional before drinking the tap water.

The source of cryptosporidium is usually animal feces . The parasite causes severe diarrhea and is believed to have sickened hundreds of Baker City residents this summer.

A water advisory was issued July 31 and a boil order followed days later.

The Baker City Herald reports officials will continue to closely monitor the water.
