Any processed food or mass produced food must be assumed to be cross contaminated.
Irresponsible, but my sympathies to the family. Publix isn’t liable.
This was probably one of the cookies bought from behind the glass case of the bakery that they put in regular bakery bags that don’t have labels.
The mother is looking for someone to blame for her own negligence. If she has a child with nut allergies, she should know that ANY bakery item is not 100% allergen free.
Meanwhile, I guess the rest of us Publix customers will face increased cost and possible new inconveniences as they implement measures to insure this doesn’t happen again.
