I eat a vegan diet so it is mainly vegetables(which I do think about dirty hands touching before mine, so wash thoroughly) and legumes etc which I create meals out of myself that no one else touches( or breathes on) but me. I eat very little processed food.

When I was a kid I would not eat or drink anything until My mother had confirmed how long it had been in the fridge,if she thought it was still okay to eat/drink and if she thought I would die if I ate/drank it,and then to be sure, I would make her taste it(like a royal taster) just to be sure. ( The downside of such germaphobia was that I could not eat or drink anything if she was not home )

Although, I am not hat bad, I do not like people touching my food and would never eat anything made by someone I did not know.
