So I'm using the last of my bread flour and Yeast to make children pizza. Flour is sold out near me of any kind! So there's me Getting a bowl from under the cupboard, I pour in all my pizza ingredients and then see a dead spider and some web on the corner of bowl. I forgot to Rinse it! Will this flour be safe to eat now having contact with this dead spider. I can not afford to throw away 600g of flour and yeast when I currently can't get anymore !
