I don't know, but all my friends with food allergies or a problem with bee stings carry Eppi Pins.
This was avoidable.
From what I read elsewhere, she did have an EpiPen, and did use it on herself before passing.
“Not long after having eaten, Tangsuan began having trouble breathing, went into a nearby restaurant and collapsed. The complaint says she was having a “severe acute allergic reaction to the food served at Raglan.”
Tangsuan used her EpiPen to help stop her allergic reaction while a bystander called 911, the complaint says. Her husband, who had gone back to their hotel room, was unaware of what was happening, it says.”
