Chicago Public Schools sent grief counselors to Edison Regional Gifted Center on Monday after the death of a seventh-grader who had an allergic reaction to food she ate at school.

The Chicago Tribune reports Katelyn Carlson, 13, of the Sauganash neighborhood, was rushed from the Albany Park school at 4929 N. Sawyer Ave. to Swedish Covenant Hospital on Friday afternoon and transferred to Children’s Memorial Hospital, where she died of anaphylaxis, a severe reaction to a food allergy, according to Fire Department officials and the Cook County medical examiner’s office.

CPS officials said they were conducting an investigation and could not provide details. Two parents of other students said they had been told by school officials that Katelyn had a severe allergic reaction to peanut oil from Chinese food ordered from a restaurant for a class party.

Matthew Akinrinade, whose daughter was a classmate and close friend of Katelyn’s since kindergarten, said his daughter also has a peanut allergy and assured him earlier last week that a teacher had called the restaurant several times to make sure peanuts would not be used in the food. Akinrinade said his daughter did not have a reaction to the food Friday, but she saw that Katelyn was having trouble breathing.

According to the American Academy of Pediatrics, food allergies affect approximately 1 in 25 school-aged children, and 16 percent to 18 percent of children with these allergies have had a reaction in school.
