Stomach acid has a PH of 1-2, it also contains other chemicals that make the stomach a pretty hostle enviromwnt. Indeed, up until quite recently it was though that pretty well nothing living could survive in the stomach and that this was the main reason why the bacterial theory for stomach ulcer causation was initially treated with sceptisisim.

Soooo

How can you get sick from eating undercooked chicken etc???

I don’t know the answer, and I know you qualified your statement by saying ‘pretty well’, but I saw a program some time ago which said that bacteria are the most amazing life form on Earth!

They are able to survive extreme temperatures from boiling water under the ocean at volcanic sites, (well over 100 deg c), to sulphuric acid environments. Basically, there’s a bacteria which can make itself at home just about anywhere on the planet.

That’s my ‘useful’ offering so far.

Did you know scientists in America have made a chicken with four legs for the consumer market?

“How does it taste?”

No-one knows; they haven’t been able to catch one yet. :D

Also it isn't the bacteria in the undercooked chicken that gives you the gyps. It is the metabolic products of the bacterial action which is poisonous and can survive the acid bath.

That was one thought that occured to me, the other was that the "Infection" could still take place in the gullet before the bugs got to the stomach even if it became an intestinal infection later

I think most of the bugs are killed off if heated, i.e cooked, properly, however not all of the toxins are broken down so easily.

I have roast and eaten beef that has gone rather brown and slimy after being left in the fridge for a week past its use by date, a good wash down with some vinegar before roasting and it was fine. A somewhat strong and gamey flavour, but rather tasty and no after effects at all.

There is no way I would do the same with mince.

...and whats the point of those live bacteria yoghurt things? They keep getting sold as some kind of health promoting thing, but surely the acid in your stomach must too? Just marketing BS then?

Yes, correct.

But promoting Bull Shit* makes money. (Still think that should be an acceptable phrase not regarded as vulgar).

So the real question is who or what do you trust?


And that is a topic all of its own....


* Sorry mods.

That was my nexe question! :lol:

Having said that, the ones that are contained in a capsule "Might" survive lone enough to pass into the intestines before disolving where they might actually do some good!

Some foods seem to survive the stomach acid bath well - sweetcorn being one!

At work, I have a bath of ferric chloride - hydrochloric acid with iron dissolved in it.
When it is warm, and you drop a piece of metal in it, it will lie in the bottom of the tank for a fortnight or so before becoming unrecognisable.

However, if you suspend the same metal above the acid and agitate it severely - spray it even, the metal will disappear completely after an hour or so.
It is the presence of oxygen which allows the corrosive nature of the acid to do it's stuff. :stirthepot:

In fact you can put your hands in the solution for short periods, with no harm - unlike the caustic soda we use to remove the protective coating on the metal which will affect your skin severely in seconds, and remove it in a few minutes! :shock:
Unlike hydrochloric acid, caustic soda is available from supermarkets and even our local SPAR shop.
Guess which one we are not allowed to pour down the drain, and which costs more to dispose of than it does to buy, and has to be handled by (expensive) COSHH qualified delivery drivers....? :scratchchin:

As you are scratching your chin it must be the Caustic Soda - you are exasperated because an estate-full of housewives are allowed to dump it in the drains but you aren't.

Or could it be the acid - you are exasperated because the less corrosive substance needs the more elaborate precautions.

Or you might be thinking that, since one of the major uses of caustic is to clear blocked drains it would be foolish to prevent people putting down the drain.

Or maybe.. :lol:

Interestingly many of the hudreds of bacteria in our gut originate from the early days of life, when oxygen wasn't around. As such oxygen is toxic to most of these bacteria.

Ahh.. Memories of making PCBs :cloud9:

All in the past now. You could say Verover :D

And their immersion in the stomach acid away from oxygen might be what enables them to carry on doing their stuff!
I was thinking of the metal in my bath - but the two might be connected in the manner I described...

It's the old "Sounds dangerous, so lets wrap it in pointless bureaucracy and make some money out of it" routine.
£25 to register as a waste producer, plus a waste transfer certificate etc. etc. and before you know it, it has cost £200 per consignment just for the paperwork! But because housewives can buy and dispose of it willy nilly, the caustic soda has no restrictions - as long as you don't tip it in a river, or put huge quantities of it down the drain at once.
As a businessman, I don't dispose of any chemical unless it is so weak it is of no further use! :roll:

Our local garage has to pay to get rid of waste engine oil.
I suggested it would be cheaper to buy an old banger that drank the stuff, and simply drive around using it up!
I never expected my humorous suggestion to be taken seriously - but it seems some Zafira owners are earning a bit on the side doing just that, according to a forum I was reading on recently! :lol:
