I am wondering, does an oven baked at 350 degrees kill all bacteria? I was baking a cake and I accidentally used scissors that weren't clean to cut the bag open with the cake mix so i am afraid to eat the cake now. the scissors didn't touch the cake mix themselves but when it was falling out of the bag it touched where the scissors touched. after i put it in the oven my mom saw the scissors and told me she used them to cut hair off of my dog! there weren't hair or anything on them but its still gross that they touched my dog and have not been clean! should i just throw the cake out?
it was in the oven at 350 degrees for 30 minutes.
