How many deaths have been caused by trace amounts of peanuts? A million? 10,000? 100? 10?
Certainly over 100 worldwide. However, there are also a lot of cases where it’s not possible to determine the trigger for an incident of anaphylactic shock leading to death. And the death toll would certainly be higher if it weren’t for the many thousands of parents and older children who are making a huge effort to avoid exposure. If one of your children had this allergy, and you found yourself in the situation this woman did, you’d being suing too. And you’d win or get a big out of court settlement.
