A 15-year-old girl with a peanut allergy died this week after being kissed by her boyfriend following his peanut butter snack.
Christina Desforges, who lived in Saguenay, just north of Quebec City, received a shot of adrenalin immediately after being kissed but did not recover.
The official cause of death was not released.
Karen Sigman, M.D., a pediatric allergist, told reporters that if peanuts are still on the tongue or the lips, they can still cause a reaction.
Sigman said teenagers with allergies have to let their friends know.
"If they're going to be dating somebody that they have to tell the people they're close to that they're allergic to make sure the people they're with aren't in contact with those nuts or peanuts," Sigman said.
