Why are you worried about fire? I know that feasibly it's possible for domestic electrical appliances to cause fire but it's really not very likely. How do you think this fire is going to start?
As an aside: if I wanted to breed bacteria, the way I'd go about it is to get some food, add moisture to it, bring it to heat, put it in a warm place, and leave it overnight. Just saying.
