ST. LOUIS — Investigators were looking into a possible link between salad bars at a major grocery chain and 33 suspected E. coli cases in the St. Louis area, a state health official said Tuesday.
The Missouri Department of Health and Senior Services said 26 people have tested positive for the E. coli strain 0157:H7. Results of tests on seven other people were pending.
St. Louis County had just five cases of E. coli in all of 2010, county health department spokesman John Shelton said.
“We are calling this an outbreak, which is a word we don’t throw around loosely,” he said.
