As the number of Americans sick from Salmonella linked to Mexican cucumbers reached 418, tomatoes have been identified as the source of a Salmonella outbreak linked to Chipotle restaurants in Minnesota.

So much for the wife’s tomato and cucumber salad, with olive oil and salt.

The Minnesota Department of Health reports tomatoes have been identified as the source of the Salmonella Newport outbreak that has sickened dozens of people who ate at Chipotle restaurants in Minnesota since late August. Investigators are working with state and federal partners to trace the tomatoes back to the farm of origin.

Since the outbreak was reported last week, additional illnesses have been confirmed by MDH.  A total of 64 cases and 22 locations now have been linked to the outbreak [locations are listed below]. Nine people have been hospitalized; all are recovering. Meal dates for the cases range from August 16 to August 28 and people became ill between August 19 and September 3. The cases range in age from 10 to 69 years and are from 13 metro counties and several greater Minnesota counties.

“We expected to see additional cases because it can take up to 10 days for symptoms of Salmonella to appear, another few days to a week before people go to their doctors and the cases get reported to us,” said MDH Epidemiologist Dana Eikmeier. “However, there is no longer a risk of Salmonella from this particular product at Chipotle.”  The company has switched suppliers for its tomatoes and implicated product was removed from stores.
