Investigation continues into salmonella contamination

Health officials still seek the cause of a foodborne illness outbreak that briefly closed a Rochester restaurant in mid-October.  Quizno’s Subs at 3499 22nd Ave. N.W. closed for one day because salmonella made 10 workers and customers sick.  "At last count we had 22 cases, only one person hospitalized and released," said Doug Schultz, spokesman for the Minnesota Department of Health. "We’re still investigating the outbreak, and part of that investigation involves produce items being the likely vehicle for the contamination."  Tomatoes are suspected, but no definitive cause has been confirmed. The restaurant re-opened after certification from Olmsted County Public Health.  Because workers got sick at the same time as customers, health workers suspect food deliveries might have been contaminated before reaching Quizno’s Subs, health officials said.
