As an offshoot of the Home Bread thread, I was remembering back to one of my first jobs (working in an ice cream factory) and how horrified I was at some of the stuff that went on there, as in extremely unsanitary, how they'd take these steam hoses that were lying on the floor where everyone walked, and stick them in the vats of ice cream stuff to remelt the misformed things on a stick, and how they'd get shut down for awhile when testing showed the bacterial count was up, but then they'd be back again doing the same things a few days later.....
I remember when I was telling some people this and it resulted in a conversation in which someone else said, "oh, and if you only knew how they made cereal, you'd never eat it again...." telling horrific cereal factory tales. And someone else saying, "If you only knew what they did at ________ (major steak restaurant chain) you'd never eat at ___________ again," etc. It seemed like everyone had some disgusting thing to say about some food place where they worked. I wonder how long the list would go on. I am hoping that manufacturing and food service practices have improved since that time. But, remembering that conversation really does make me think that ignorance is bliss but rather than be ignorant (or paranoid) I'd rather simply make my own food as much as possible.
