We have a very small Catholic /private school (pre-k /8th )and they have zero policy as well .Well due to DD eating habits she wanted to take bread and butter it at school If she did it in the Am. is was mushie.
I went to school for a solution and they gave me one ,small butter knife (ones with little char.on top ),butter had to be applied in front of a teacher and spreader turned over until we picked it up each day.This was a small price to pay but well worth it as she ate every day and we did not comprimise the safety at school.
We just had a 5th grader Expelled for stabing a girl with a pencil
