Where did she get it?

Dade City teen charged in mother's allergic shock - St. Petersburg Times:

"The teen told deputies that she added the seasoning salt to the meal, knowing her mother was allergic to the ingredients. She said she did not mean to hurt her mother and she was sorry for what she had done."

Okay -- so if you were highly allergic to something ... why would you have it in your home??
I'm deathly allergic to fish -- sorry, other than the recent mix up with the Worstershire sauce, we have NO fish in the house.

Not that the mom is to blame for the kid trying to kill her ... but where the hell did she get the Seasoned Salt from?
