A salmonella outbreak in the water supply of Alamosa, Colo., in 2008 has prompted 29 local families to file a lawsuit against the city. The Denver Post reported that up to 1,300 people may have become ill from salmonella, including 40 percent of the city’s infants. The state’s health department concluded that the outbreak was probably caused by animal feces that got into the water supply. The lawsuit seeks unspecified damages.
