A 7-year-old girl with an extreme allergy to peanut butter was hospitalized for two days after she was allegedly attacked on a St. Louis school bus by a boy with a peanut butter cracker, according to a Local 6 News report.

Arionna Lunceford said a boy was harassing her on the school bus about her allergy to peanut butter and then shoved a peanut butter cracker in her face and then dropped pieces of it on her head.

Lunceford collapsed moments after getting off the bus in her hometown of Ladue and had to be rushed to the hospital to be treated for an asthma attack.

Arionna's mother said the second-grader could have died because her air passages close up when she gets too close to peanuts.

"It's like I can't breathe and I'm going to die," the girl told reporters.

"There are definitely people who are sensitive and just having the food in the general vicinity is enough to set off an allergic reaction or allergy attack," St. John's Mercy Medical Center spokeswoman Dr. Kristen Soehngen said.

Doctors said the number of cases of peanut allergies has risen 50 percent in children over the past five years.

The Ladue, Mo., school district has a policy of no eating on school buses, in part because of such allergies.

Arionna's mother said she's thinking about moving out of the district because of this incident.
