My family likes to eat fish. With all this talk about mercury content
in fish I am wondering if there is a reasonably quick and easy way to
measure  dangerous levels of mercury content in fish?
Henry Boyter - 11 Jan 2004 05:10 GMT
No, there is no home kit / easy way for the low levels of mercury involved.
You also have to grind up the fish.  Kind of defeats the purpose
of testing.

Not really. One could grind up a representative sample and eat the
rest.

OK, what about an ingredient to add to the fish dish to neutralize or
bind the methylmercury?  Milk products maybe?  Something in the form of
a spice?  Big market for this..

You're totally fixated on amalgam, I suppose thats normal when one has

As Mark has so subtley pointed out cilantro is an option in detoxifying
methylmercury. My apologies Joel, I'm not a naturopath so I'm not
familiar with these remedies. If you hadn't made a joke out of it (the
gargling bit -or did you mean that?) I would have looked into it.
Cilantro seems to mobilize methylmercury in the brain and move it out,
but other herbs are needed to bind it in the gut and get it out of the
body.
But still, who would have thought that good old coriander had these
properties?

Oats.

What's your opinion of jokes that relate to things that cause death as
a topic in general?

Myocardial infarction jokes?
Stroke jokes (no double entendre intended)?
Murder jokes?
Suicide jokes?

Its best to stick a meat thermometer into the raw fish. If it does not
move then the fish is safe - as per FDA guidelines.

That prompted me to ask this: In this particular store grocery, they
put a label on Salmon saying that *color added*. I never  When I
inquired about it, the guy said ..."Oh ..they were fed carrot or

REPLY:

This may not be so. I tried fishing once with a carrot tied on the end
of my pole, but I got no bites.

(A couple of donkeys came by though and looked interested.)

Joel...fess up.  When are you people
going to admit, that mercury, like
beer, is an essential vitamin without
which no man can live.

    Waldbaums' label on their salmon reads "color enhanced through feed".
    Maybe they feed them Man Tan?

The fish are fed Phaffia rhodozyma biomass. This yeast contains high
concentrations of the carotenoid astaxanthin.

Why are flamingos pink? Maybe because they eat red pond scum,
rife with yeasts like Phaffia?

Hope this helps,

Thanks!

Jan Drew's posts always appear pink on my monitor ...... I bet it has
to do with pond scum also!

They can be, however other sources of astaxanthin are also
used, such as _Haematococcus_ algae and waste from
shrimp processing plants.  There is also synthetic astaxanthin.
Recently, a test has been developed which can distinguish
between the meat of fish that have eaten astaxanthin from
natural sources which consists of a single optical isomer
and synthetic astaxanthin which consists of a racemic mixture.

My explanation was slightly incorrect.  There's more than
one isomer, and the composition of natural vs. synthetic
is not as simple as I implied.  For more information,

They feed them a naturally occuring carotenoid called Canthaxanthin.
Some people are concerned about this.
Joel M. Eichen D.D.S. - 12 Jan 2004 17:22 GMT
How do they get the fish to chew their carrots? Do they serve them
with a nice Hollandaise sauce?

Sounds like Purdue chicken commercials where they boasted that they feed
their chickens marigold flowers to get a nicer yellow color.
