111 students fall ill after prom at Shedd Aquarium

CHICAGO — At least 111 students from a suburban high school became ill with stomach flu-like symptoms after their Friday night prom at the Shedd Aquarium.

Roughly 400 students from Andrew High School in Tinley Park, Ill., celebrated prom at the aquarium at 1200 S. Lake Shore Dr. on Friday. By Saturday and Sunday, some students started to come down with fevers, chills, vomiting and diarrhea. It is still too soon to tell whether the illness is norovirus.

Officials originally reported that 50 students were ill. By Tuesday morning, the number had climbed to 111.

A spokeswoman for Shedd said the aquarium's food provider, Sodexo, was investigating. Shedd did "an extra precautionary deep clean of the aquarium" Monday; no one at additional private events hosted at the aquarium since Friday became ill.

“At this time, we do not believe there are any safety concerns related to food or drink being served to our guests visiting the aquarium,” spokeswoman Andrea Rodgers said.

All known details have been reported to the Chicago Department of Public Health.

School officials are asking parents of students who became ill to contact the dean’s office to provide more information. School officials want to know what the students ate, in which activities they partook and when they first saw symptoms.

Kacie Johnson, a senior, said she felt ill by Saturday and had stomach cramping Sunday morning.

Marci Condon said her son Jack, a football player at Andrew, was still sick in bed Monday. Dozens of students went to Kalahari Resort in Wisconsin Dells and became sick there. Others fell ill on trips to Indiana, Michigan and Six Flags Great America.

“Clearly, my heart goes out to all our kids and their families who were affected," Principal Bob Nolting said in a statement. "We have many individuals who work very hard on creating a prom experience that is enjoyable and meaningful. It is saddening to see the excitement of an otherwise positive and memorable event dampened by this situation."

The high school said it is taking steps to sanitize the school.
