Not A Dirty Story.

Currently on Australian TV (and probably on non-Australian TV) there is an advertisement for a popular brand hand sanitiser where two small boys are refused service at the icecream van until they have sanitised their hands.

Am I the only person uncomfortable with this?

In the coffee shops and supermarkets I see young mothers cleansing the kids with these chemicals. I see people wiping their cafe tabletops with impregnated sterilising cloths before they sit down and order. Homes stock up on anti-bacterial fluids and sprays.

It’s a dangerous thing, y’know.

I am certainly not an anti-vaccination person – exactly the opposite in fact …please VACCINATE YOUR KIDS! – it is important for them.
But please think before you stop them playing in the mud, playing with the dogs, and getting dirty.
That play and dirt is a kind of natural vaccination, it’s a resistance builder.
Hand sanitisers over-used do the opposite.

Before I became a Flâneur, Artist, Photoist, and retired idler, I worked not only in the church, but in science too – for more than 20 years.
I have studied biology and microbiology – I know stuff (OK – not as much as I did, but enough).

If you manage to knock out 99.5% of harmful bacteria from your cooking surfaces, what do you have left?
0.5% of the population of those harmful bacteria, that’s what.
The thing is, that 0.5% of bacteria are the ones that are strong enough to resist the killing agent with which you’ve hit them.

By doing this continually, as the manufacturers suggest, you are weeding out the weak bugs, who form the majority, and selecting the strong ones – the resistant ones
… you are line breeding a population of strong pathogens
– you are aiding the evolution of strong bugs!

Remember – 0.5% of 1,000,000 bacteria is still a big crowd of 5000 bacteria whose population may double every 20 minutes or so
… that means that in less than 3 hours you’ve got more than you started with
– but they are the strong ones.

I’m not saying “Don’t use cleaning products”.
I’m suggesting that none of us over-use cleaning products.

Don’t be scared.
Look after yourselves, your children, and your homes
– but please don’t get carried away.
