As many as 140 students will need to be tested for E. coli after a recent case matched a previous cluster of infections that occurred in August and early September, according to the Green County Health Department.

Three students at Abe Lincoln Elementary School, in the Monroe School District, have the E. coli infection.

In response, the Green County Health Department and the Wisconsin Division of Public Health have recommended stool testing for all pre-kindergarten and kindergarten students who attend Abe Lincoln Elementary School. Stool collection kits have been prepared for distribution.
