Is it slugs?

[kt.]

I pulled my Pentland Crown spuds today. They were planted in a bed section near to next doors overgrown part of his plot. There appears to be a lot of light brown, smooth markings around about 1/2 of the spuds. Its not worms and its not blight as it is not soft. I think it is where slugs have slid around them. I have scratched back the skin in these areas & they are fine otherwise.

My questions are:
1) if it is slugs: Are the spuds OK to eat still as it appears to have dried throughout the day but is still marked, .
2) if it is slugs or if not: would they still store.

I'm not sure, but we have had a few potatoes similarly afflicted, and I thought it could be potato scab.

We've been eating them, and they have tasted OK, but I'm not sure about whether they will store.

we've had some scab affected spuds, taste ok and we just use them first  :)

I think I know the sort of thing you mean, I eat them, the scab rubs off with the skin. The shop-bought ones also often have it. If we're talking about the same thing.
