Nope, it's absolutely disgusting, if you ask me.
I lived in an old house a long time ago and it had a flooded concrete safe-house in the back (like a tornado shelter, it was partially underground and the door had caved it - it was moldy, flooded and the most stinkiest place I've ever had to be). Apparently that shelter was used as storage of a lot of crap. Everything from books to around-the-house items like kitchen accessories and so on for some reason. There was everything you could and couldn't imagine growing in there and living in there, too - magots and everything. It was putrid. The water was so stagnant it had a layer of scum on top where things had collected and started to rot. It was horrid.
Well, we emptied it and tore the safe-house appart, got rid of it all and leveled the mound around it.
We put the trash from the inside at the road - called the trash company and set a pickup date. Two days later that pile of years old disgusting crap was picked through adn half of it was gone, including some of the kitchen accessories.
There's no way in hell any of that was sanitary - and some things would be impossible to clean. I can't imagine the filth that some people took home on those things and then infested their homes with.
So, dumpster diving is beyond disgusting - you have no idea where some of that stuff has been or why it's being tossed out. Some things are trashed for a reason.
Like, O - M - G. GERMS! So Gross!!! Like Totally!
