Salmonella sickened eight people who attended a function at Clearview High School in Lorain, Ohio, according to the Lorain County General Health District.
Health Commissioner Kenneth Pearce said an Ohio Department of Health laboratory analysis confirmed that all were positive for Salmonella B. Meanwhile, local health investigators are trying to determine the source of the illness.
Pearce told the Morning Journal newspaper the investigation is focusing on a weekly football team dinner that all eight victims attended.
The Chronicle-Telegram newspaper said at least two of the confirmed Salmonella cases were members of the football team.
Those infected with Salmonella were among about 100 students reported to have been out sick during the first week in October, but the high rate of absenteeism at the high school likely was coincidental to the Salmonella outbreak, Pearce told the Morning Journal. He said the majority of ill students probably had upper-respiratory problems.
Lorain is located about 30 miles west of Cleveland on Lake Erie.
