Toddler and dirt. WIBU?

[DontBuyANewMumCuntingDailyMail]

Is it realistic to never allow a toddler to put 'dirty' hands to their mouth?

17mo DD was playing in the garden and inevitably had dirty hands - I don't mean covered in soil, I mean she had been splashing in a bucket with garden tap water and a touch of soil in it, and splashing the water in her face.
She put them to her mouth and DH quickly said No xx, don't put dirty hands in your mouth.

Then a short discussion about whether we should always stop her doing it.

DH thinks the bucket is filthy, the water is dirty, the soil is full of germs, etc etc

My opinion is that it'd be near impossible to always stop her putting germy hands to her mouth, and a bit of garden dirt isn't too bad. I think she'll be eating sand, soil, worms etc before she's grown up and unless there is something very dirty like bird poo, dog mess etc then I wouldn't make her wash her hands every time she touched something, just on the off chance she went on to touch her mouth.
Moreover, from experience, if I say to DD 'don't put your hands in your mouth' she'll do it even more as a game. I'm kind of hoping she'll eat some soil and it'll taste rank and gritty and she won't do it again.

Am I being unhygienic and unreasonable?

soil is rampant with threadworms

Threadworms aren't found in the soil, unless raw sewage has been spread on it.
They are passed from anus to mouth.

• The worm lays eggs around the anus, which becomes itchy.
  
• The itchy bum gets scratched, transferring the eggs to the hands, which then either go into the mouth, or transfer the eggs to toys, toilet handles, food, drinks, and occasionally pet fur, to be picked up by someone else's hands.
  
• Those hands then go in the mouth, and the cycle continues.
  
  You're more likely to get threadworm by going to nursery than by eating soil.

When dd was a toddler she picked up and started to chew a dead mouse the cat had left for us...she's 13 now so it hasn't done any harm.

My parents were quite relaxed about that kind of stuff.. we were forever making garden "potions" the grosser the better.

When we were tots my DSis thought SANDwiches should really contain the element of their namesake and happily filled our entire picnic with sand. The whole family ate gritty baps that day.

I'm pretty sure it does make you stronger as I'm almost never sick and have really very strong constitution.
