Once I found out about biofilms from the cat fountain I built from NSF silver infused antimicrobial tubing, I never can look at plumbing piping the same. Biofilm formed even on the parts that should have been impervious. Even areas where water is constantly running and splashing. First the minerals deposit on the antimicrobial surfaces, and then the bacteria attach and film.

I had always thought that constant high pressure water usage would flush whatever crap is in a pipe. Preventing any real contamination. Well...a quick google search shows that biofilm on residential water pipes is a huge problem. High pressure activity does not eliminate biofilm...of course stagnant water is more of an issue...

You probably don't want to know how we filter our water then [1]:

"Slow sand filters work through the formation of a gelatinous layer (or biofilm) called the hypogeal layer or Schmutzdecke in the top few millimetres of the fine sand layer."

Treating all bacteria as the enemy is really solving the wrong problem — the question is not how to kill all the bacteria (which is impossible, from almost thermodynamic considerations (if there is free energy and the ability for life colonize it, then there will be life)), but how to manage the bacteria so we favor nonpathogenic or useful species and help them outcompete the 'bad' bacteria.

Incidentally, this is the same strategy our own bodies use—the immune system spends enormous amounts of effort discriminating between commensal/mutual and pathogenic species, and favoring the former as much trying to outright kill the latter.

We need to pick the right analogies. How to herd, tame, and recruit allies, not just how to fight and kill.

However, washing in a water & bleach sanitizing solution will.

You generally don't cook romaine lettuce prior to making a salad.

You wash your vegetables in bleach before eating them?!

How do you think industrial farms wash vegetables?

That's what I was thinking. Talk about taking away any benefits of eating salad... more bleach please?

Downvoting me for this was stupid. You know know enough about food if you think bleaching is healthy. Apart of what makes salad healthy is the bacterial culture that's naturally on it. Think probiotics that are essential to maintaining proper digestion of the food you're eating. Seriously, get downvoted for anything.

I didn't downvote you, but if you think the only thing that makes salad healthy are it's probiotics then you also don't know enough about food.

Any cooking method that would kill ecoli will also destroy those helpful bacteria.

Factory farms in the US wash their vegetables with chlorinated water.

"if you think the only thing that makes salad healthy are it's probiotics then you also don't know enough about food."

Learn about the gut micro-biome. The main reason salad is good for you it's effect on gut.

We eat to feed the gut, not ourselves. To imply that prebiotics/probiotics aren't the main reason vegetables have a positive health effect on us is beyond ignorant. That's the reason why diabetes, cancer and heart disease is now worse than all the wars of history combined.

So just take a bunch of probiotics with your steak n shake, and call it good?

And, you meant to say salad that hasn't ever been washed in chlorinated water is good for you.

"So just take a bunch of probiotics with your steak n shake, and call it good?"

Are you taking the piss?

"And, you meant to say salad that hasn't ever been washed in chlorinated water is good for you."

You're the one putting words into my mouth. I never said that because I don't believe that. Salad that's fresh from a traditional farm using healthy soil, practices and cultivar is good for you.

If you're satisfied with nutritionally bankrupt, sterile food, fine. Good for you.

So you go visit the farms and check to make sure the soil is healthy?

You're right - I think it was more-or-less to prevent norovirus and other forms of food poisoning.

Doesn't Norovirus mostly spread from people not washing their hands after they poop?
