> I have understood it to be that the copper interacts with the food being cooked and produces a poison.

You'll notice the flavour long before it becomes poisonous, no matter how strongly flavoured the food is.

Copper toxicity is, I think, cumulative. (Remember reading something about copper, Patterson's Curse, livestock, and kidneys.)

Unless you don't...

hehe ... and I just realised I asked the genetic question the wrong way around.

(my hazy memory of the same thing) I have a feeling that "Curse" causes a copper deficiency in sheep, its why they keep a black sheep in the flock if the sheep gets white spectacles around its eyes the flock is copper deficient.

Could be that Wataday. Just a vague recollection of something about copper.

and "staggers"?

and putting copper sulphate(?) I think ... into the water supply for the sheep?

*goes a-googling*

[FUNALA]

I grew up in an area that had no sheep and little Patterson's Curse, so have no direct experience.

[Adimondin]

nup, staggers is cobalt related ... still looking.

Now there's an interesting historical story

Class distinctions / discoveries / all sorts of history, both academic and social and (SA) geography.

nice to read an alert about metal poisoning

Given that it is OK for water both hot and cold it is not OK..... toxic substances in water (eg shower) are absorbed through the skin....

Cooking is the downfall of humankind
so be careful of the pots you use... [I suggest cast iron or stainless steel...best is glass]
remember the accumulation is insidious and can be personally "undetectable"
see Wilson's disease

Copper
Pregnant ewes require ~5 mg of copper (Cu) daily, which is the amount provided when the forage contains ≥5 ppm. However, the amount of copper in the diet necessary to prevent copper deficiency is influenced by the intake of other dietary constituents, notably molybdenum (Mo), inorganic sulfate, and iron. High intake of molybdenum in the presence of adequate sulfate increases copper requirements. Because sheep are more susceptible than cattle to copper toxicity, care must be taken to avoid excessive copper intake (see Copper Poisoning). Toxicity may be produced in lambs being fed diets with 10–20 ppm of copper, particularly if the Cu:Mo ratio is >10:1. The Cu:Mo ratio should be maintained between 5:1 and 10:1.

I'll drive down to the shops in my water powered Land Rover to get some right now


*GONE*

my gawd ... wait for me!!!

I grew up on cast iron cooking pots ... ... not going back to them for everyday use .. though I do love them *sometimes*.

[Pvfcadbh]

I'll drive down to the shops in my water powered Land Rover to get some right now then you won't pollute

my water powered engine has now been perfected
and the best part is that there is no toxic exhaust.... I can sit in my sealed tin can with the engines screaming..... nice

nope. not a thread on the guy who has recently been charged with exposing minors to amphetamine processing. I'll assume the 'cooking with gas' thread intentionally included the 'with'.

All things sheep, just for JJ.

"Copper toxicity
Sheep are ten times more susceptible to copper toxicity than cattle. When consumed over a long period of time, excess copper is stored in the liver. No damage occurs until a toxic level is reached at which time there is a hemolytic crisis with destruction of red blood cells. Most outbreaks of copper poisoning in sheep can be traced to feeding supplements containing copper levels that have been formulated for cattle or swine.

Copper is closely related to molybdenum, and copper toxicity occurs when the dietary ratio of copper to molybdenum increases about 6-10: 1. Affected animals suddenly go off feed and become weak. An examination of their mucous membranes and white skin will reveal a yellowish brown color. Their urine will be a red-brown color due to hemoglobin in the urine.

Treatment of copper toxicity involves the use of ammonium molybdate and sulfate compounds."

OK, looks as if I got two half-remembered stories mixed up. One was copper toxicity in sheep, as just related and the other one about Patterson's Curse.

I did too geoff d.

I remember chanting
"molybdenum and malgic adrenalin cream" to a skipping (rope) game when a kid on the farm ... there were other word play chants but that was one clearly to do with ... who knows!
