A Quebec teen with a severe peanut allergy did not die from kissing her boyfriend following his snack of peanut butter, a coroner has confirmed.

Michel Miron says the sudden death of fifteen-year-old Christina Desforges in November 2005 was not caused by a peanut butter sandwich.

The tragedy made headlines around the world.

Miron would not reveal the official cause of the teenager's death because he said he hadn't yet submitted his final report and is still waiting on some test results.

But Miron said he wanted to speak out before the case was mentioned in a forthcoming initiative by the Canadian Association of Food Allergies.

"The Canadian Association of Food Allergies intended to use the Desforges case to launch an education campaign," he told Saguenay's Le Quotidien newspaper. 

"I had to tell them the cause of death was different than first believed."

Miron also said the teen, who lived in Saguenay, Que., did not receive a shot of adrenalin immediately after being kissed by her boyfriend.

Earlier reports suggested the shot hadn't penetrated her skin.

Miron said scientific journals had contacted him questioning the use of the adrenalin shot and how it was injected.

He said the teen did not use her syringe to give herself a shot of adrenalin because she didn't have an allergic reaction to peanut butter.

Saguenay is about 250 kilometres north of Quebec City.
