Waterborne outbreak of Salmonella I 4,[5],12:i:-.

Salmonella I 4,[5], 12:i:- is an emerging serotype, and little information regarding attribution or risk factors for infection has been documented. We investigated an outbreak of Salmonella I 4,[5], 12: i:- infections in a rural community and identified the community's private water system as the source of infection. Five people were ill with gastroenteritis. Water testing identified Salmonella. Contamination of the unprotected spring from an environmental source was suspected.
