City recommends boiling drinking water
Five cases of cryptosporidium, a waterborne illness that can cause persistent watery diarrhea, stomach cramps and a fever, symptoms that in some cases mimic the flu, have been confirmed in Baker City residents the past two days, and more possible cases have been reported.
Although the source of the infections has not been confirmed, the city’s drinking water is suspected, and city officials recommend residents boil tapwater that is to be consumed or used for cooking, washing dishes or brushing teeth, City Manager Mike Kee said this morning.
The city will be flushing its water system over the next several days, according to a press release.
The city also has closed Sam-O Swim Center to drain and clean the pool.
Kee said city officials are taking water samples to be tested. Results could take several days.
All five confirmed cases involve people who are believed to have ingested contaminated water between July 12 and July 26, according to the press release.
Kee said city workers early today changed the area of the watershed from which the city gets its water. The city uses a dozen springs and streams in the Elkhorn Mountains about 10 miles west of town.
According to the Oregon Public Health Division there has been only one confirmed case of crypto in Baker County since at least 1999. The agency’s report doesn’t list the source of that case, which happened in 2007.
Officials from the state Health Division are traveling to Baker City today to try to pinpoint the source of the infections.
St. Alphonsus Medical Center-Baker City confirmed that crypto was responsible for the symptoms that brought people to the emergency room, Kee said.
Water should be boiled (rolling boil) for one minute, according to the U.S. Centers for Disease Control and Prevention.
According to the Health Division, symptoms of cryptosporidium infection (technically it’s called cryptosporidiosis) in healthy people usually are relatively minor and do not require emergency room treatment.
Diarrhea can cause dehydration, so people with symptoms should drink plenty of fluids.
Pets also can be affected by cryptosporidium, said Dr. Emilio DeBess, public health veterinarian. Pet owners should boil water for their pets as well or provide bottled water.
A prescription medication called nitazoxanide is sometimes used to treat diarrhea caused by crypto.
The city has until Oct. 1, 2016, to install equipment that would remove crypto from its water.
Three of 24 samples of the city’s water, collected in April 2010, October 2010 and January 2011, each contained relatively small amounts of crypto. No cases of illness were reported during that period.

Cyrptosporidiosis is a diarrheal disease caused by the microscopic parasites of the genus Cyrptosporidium. If the parasite is swallowed, then that person or animal becomes infected. It’s not possible to be contaminated through blood contact. Cryptosporidium can be found in soil, food, water or surfaces that have been contaminated.
• watery diarrhea
• weight loss
• stomach cramps or pain
Symptoms appear two to 10 days after becoming infected. The average amount of time between exposure and signs of illness is seven days. Some have no symptoms at all.
