(NBC6 MIAMI) -- A South Florida mother says her 15-year-old daughter died after mistaking a Chips Ahoy cookie with peanut butter for a regular cookie and now her mother is calling for the company to make distinguishable packaging for foods with allergens.

Alexi Ryann Stafford, of Weston, made the fatal mistake when she was at a friend's house and reached into an open package of chewy Reese's Chips Ahoy cookies, thinking it was safe for her to eat because of the familiar red packaging. The top flap was peeled back, hiding the Reese's label on the package.

"She started feeling tingling in her mouth and came straight home," her mother, Kelli Travers-Stafford, wrote in a Facebook post Thursday.

Travers-Stafford said they administered two EpiPens while waiting for paramedics to arrive. Stafford quickly went into anaphylactic shock, stopped breathing and went unconscious.

She died on June 25, within one and a half hours of eating that one cookie.
