Cases of shredded romaine lettuce distributed to delis, schools and a host of institutions around the metropolitan area have been recalled because of a potentially deadly E. coli contamination — trigging a queasy feeling for salad eaters around the city last night.

At least two people in New York — a Daemen College student in upstate Amherst and another person in Dutchess County — were sickened by the bacterial outbreak.

Another 17 in Ohio and Michigan also were sickened, prompting the recall for romaine sold in 23 states and the District of Columbia, authorities said.

The New York state Public Health Laboratory in Albany discovered the contamination in a bag of Freshway Foods shredded romaine on Wednesday.

A spokeswoman for the city Department of Health had no immediate information about any reported illnesses in the city.

The state Health Department said the two upstate patients were “recovering.”

The Food and Drug Administration is focusing its investigation on lettuce grown in Arizona, according to two sources.

E. coli infection can cause mild diarrhea or more severe complications, including kidney damage.
