Health officials are still searching for the source of 15 cases of salmonella reported here in late May and early June.
Julie Goplin, an epidemiologist for the State Health Department, said the first case found in Williston was May 23 and the last cases were reported June 14. Health officials said one woman, who was older than 65, died. She has not been identified.
A food supplier may be a source of the salmonella, but no link to all the cases has been pinpointed in Williston, she said. DNA samples taken in North Dakota have been sent to the CDC to see if they match samples that were taken in 17 other states.
