Black marks on boiled (shop bought) potatoes?
 

Never really noticed it before this year, but a few times I have
boiled potatoes they start developing black marks/stains the more they
boil. The spuds looked clean with no blights after I peel them.
Anything to worry about and why?

Is that always the cause of black marks? I now feel quite ill at some spuds
I've eaten.

Talking of which, I got a bag of king edwards a while ago from Sainsburys
that had something very wrong with them; sort of raised roundels that looked
like craters on an asteroid. I tried cooking a couple (yes, I am rather dim)
and they tasted horrible. I don't know anything about potato diseases, but
there was definitely something weird there, like some kind of scab or
something.

You might like to have a butchers (or just a look if you're
vegetarian) at the Potato Council's website at

http://www.potato.org.uk/department/...?menu_pos=sbeu

There's a website for everything out there somewhere ;-))

Scab is what it's called. All benefits of organic farming.

Or if you want a comprehensive list of everything that can go wrong:-

Don't worry, you won't die. :-)

Looking at pictures it doesn't appear so. The spuds are perfect to
look at (hence buying them) and while peeling you get the odd eye etc,
but once peeled they are spotless. I then chop them up to boil and
after about 15 minutes these black smears start to appear and get
darker. Seem to only be on the surface but quite large in area. Boiled
in a stainless steel saucepan and slightly salted with sea salt. It's
only ever happened once before a few months back, and could also have
been sourced at Tesco.

PS: Sometimes when you leave boiled spuds in the fridge, the next day
a few would usually have these black marks too, I wonder is it the
same thing and still safe to eat?

The blight has progressed further that's all. The picture is an
extreme case.

I trust you took them back!

I didn't actually, but I should have done.
