Panera Bread was slapped with a lawsuit last week after a 6-year-old girl with a serious peanut allergy was allegedly served peanut butter in a grilled cheese sandwich.
The parents of the young girl said that when they ordered the sandwich online, they noted twice that it was for a child with an allergy, according to The Boston Globe. The girl was hospitalized after biting into the sandwich.
Panera Bread did not immediately respond to CNBC's request for comment.
According to the John Russo, the girl's father, the manager of the Panera Bread in Natick, Massachusetts, apologized and blamed the addition of peanut butter to the sandwich on a "language" issue.
