The Southeast District Health Department confirmed an outbreak of salmonellosis in the Blackfoot area Tuesday. The four laboratory-confirmed cases are currently under investigation.

The environmental health supervisor for the health department Mike Reas said because the source of the contamination hasn’t been pinpointed yet, the health department is currently interviewing people who have the symptoms of salmonella. He urges anyone currently suffering from the symptoms of salmonellosis to contact a physician and seek medical attention.
