>>This is my
>>son's sixth year in that school and he has never had a reaction at school. 

This is overly simplified.  He has had contact reactions that have caused 
hives.  He has had wheezing that we were unsure if it was asthma or a 
reaction to milk.  He has never been given an Epi pen injection at school.  
He has a very complete emergency plan and I have full confidence that it 
would be followed to the letter in the event of a serious reaction.  The Dr's 
orders for contact reactions is to wash the area, give Benedryl and monitor 
his breathing.  We have done this a few times at school and at home.
