PORTLAND – Food-borne bacteria caused around 60 Sandy River Outdoor School students and student leaders to become sick earlier this month, officials said.
Approximately 55-60 students and student leaders of the 139 children and adults at the Sandy River Outdoor School became sick on Oct. 8 with stomach pains and diarrhea.
Laboratory results showed that beef stroganoff served at the school contained the bacteria, Multnomah County Health Department officials said.
The Multnomah County Health Department said no one had to go to a hospital and no new cases were reported after the initial outbreak.
Sandy River is one of three sites where the Multnomah Education Service District teaches sixth-graders about the natural sciences in outdoor classes.
