WCCO.com reports that a Rochester, Minn. sub shop is temporarily closed after 10 people were sickened in a case of suspected food poisoning.

Olmsted County environmental health director Rich Peter said the Quizno's restaurant was closed by its management as a precaution.

State Health Department spokesman Doug Schultz said 10 people became sick, including three workers.

Schultz said the illnesses were related to "some type of salmonella." He says if people are showing signs of salmonella should see a doctor.
