That is a scientific experiemental test that I want to be invited to, eh??
I wonder if it's white cheese from this same manufacturer??
I love cheese, White Cheddar in particular, so I'm very sorry to hear your having allergy issues
Awhile back there was someone here with a Soy allergy and everytime they went to *$'s the hand they held the cup in became red and itchy like the outside of the cup was contaimanated by the barista.
Allergies are soooo weird!!!
Hope you find out and if you need help testing just let me know!!
