A group of friends shared a rotisserie chicken that had been purchased at the Willison, North Dakota, Economart. Three developed Salmonella Typhimurium. An unrelated family became ill after eating a second rotisserie chicken, as well as additional persons in the community. Some of the ill reported buying prepared food at the Economart. Food handling procedures that were critical for safety were found to be deficient at the market.

A later Williston Herald newspaper report stated that state health department had determined that the source of the outbreak was not local. The strain of Salmonella in this outbreak supposedly matched strains that were causing illnesses in other states. The report mentioned that a food supplier might be the common source. A multistate, orange juice associated outbreak of Salmonella Typhimurium and Saintpaul was concurrent with this outbreak, but no information about how this outbreak might have been linked to the other outbreaks was offered in the newspaper report. The Centers for Disease Control report for the orange juice associated outbreak did not show reported cases from the state of North Dakota.
