Alamosa, Colo. (AP) Alamosa officials say there are now 47 confirmed salmonella cases in an outbreak in Alamosa out of 123 being investigated by health officials.
State health officials have advised residents to use boiled or bottled water for washing dishes, cooking, drinking, making ice and brushing teeth because the tap water may be linked to the outbreak.
Health officials say city water tested positive for bacteria believed to be salmonella.
The cause of contamination is being investigated. Flushing and disinfecting the water system could take a week.
Meanwhile, three distribution centers offering free bottled water have opened in Alamosa, and hoses are available at a fourth center for residents to fill up on safe water.
