The state laboratory in Frankfort has confirmed a seventh case of E. coli bacteria infection thought to be linked to the nationwide outbreak from tainted fresh spinach.

A male teen-aged Kenton County resident received outpatient treatment for the illness, a particular strain of E. coli O157:H7, said Gwenda Bond, spokeswoman for the Kentucky Department for Public Health reports the Lexington Herald-Leader.

Of the six previously confirmed cases, an Oldham County woman remains hospitalized. In addition to the Kenton County case, two cases have been identified in Oldham County, two in McCracken, one from Hopkins and one from Jefferson.

The Department for Public Health also reminds people to continue to avoid eating fresh spinach products to avoid potential infection.
