It depends on how you treat the ferrets.
But ferrets are also known to be pets, nice ones too!
So they aren't that dangerous if you be nice to them though they get nervouse and bite you sometimes (Or if they think your hand is a toy)
But as you get along with the ferrets, then you'll be fine
Now I'm talking about how clean a ferret is?
Ferrets are messy creatures (But don't count that as Germs)
They can make a big mess everywhere (They are playful)
But when a ferret is sick, its not sick because its a dirty creature,
But the environment that the ferret is living made it sick
And it's not their fault
Its (Usually) us!
Castrating gives them a high chance of Adrenal disease (Castrating means doing something so it cant have baby)
If a person is sick, and feeds the ferrets (Or something)
this will past the sickness to the ferrets!
So, ferrets are safe after all, but remember, the behaviour and safety really depends on YOU! (How you treat them, where you put them, how you care them)
It depends on the animal, the breed and how it is cared for by it's owner. According to the AMVA (American Medical Veterinary Association) the number of dog bites that required medical treatment, the latest statistics were 800,000. And how many were unreported? Many people have died from dog bites. I don't think a ferret has ever killed anyone. Ferrets do bite, as any animal. A safe pet is one that is properly handled, taken care of and never abused.

Ferrets may suffer respiratory illness or allergies from pine or wood products
Mice form part of the wild polecat's diet, meaning that while eating them will present a slightly increased chance of your ferret contracting disease from the mice (they may also get fleas), it will be safe enough to not worry about. I suspect that, if you keep ferrets and have mice in your home, it'll be almost impossible to stop the ferrets eating them!
A ferrets favorite activity is a dig box - a container filled with long grain rice (DO NOT USE instant rice). Other alternatives can be - potting soil, play sand, dried beans, ping pong balls, or pebbles can also be used to satisfy your ferrets digging behavoir.
Petroleum distillates would be safe for ferrets IF the product is made specifically for ferrets to be used to treat ear mites.
Ferrets are not caged animals, but you cage them for their protection. Most ferret owners cage ferrets when they're not at home or unable to supervise them when free roaming. Ferrets need about 4 hours daily time out of their cage in a ferret proofed environment. Ferrets being burrowing animals by nature are subject to crawl and fall asleep into places that can be dangerous and you cannot get them out, like in major appliances, couches, recliners (very dangerous for ferrets). I personally do not cage my ferrets, but keep them in a bedroom totally ferret proofed so they are safe
Ferrets are only bred with other ferrets
The collective term for a group of ferrets is a "a business of ferrets" or "a cast of ferrets".
You can put a ferret in a hamsters cage on a temporary basis as long as it's not being used to house hamster's as the ferret will kill them. A ferrets needs a large size cage made for ferrets.
