Is this mold on this rough sawn timber? Is it safe to use internally?

It's rough sawn, which is also pretty wet from lying in the builders yard.

Blue mould is uncommon on whitewood. But it might be where treatment has crystallised on the surface. I'd be more concerned about how knotty itbis and how big those knots are
 
It's wood (20 lengths) that've been purchased to frame off some stuff that will then be plasterboarded over. I'm concerned that the areas getting sheeted off (chimney breast X 2 and a bathroom) are already prone to moisture/penetrating damp. I'm feeling really uneasy about using this. My builder did try to buy planed smooth 2x2, but they were out of stock, and he's instead opted for this. It's clearly been lying out in the rain and is soaked. It's meant to be getting used tomorrow.

I hadn't even noticed the knots.
 
the mould is no big deal, the timber will dry out once fitted inside

I do hate it when merchants store it outside in the rain -builders merchants are often the culprits, timber merchants tend to have sheds, open but out of rain.

it is shockingly shoite timber though

I'm worried it won't dry out though. Not quick enough considering it'll be sheeted same day - in an area already prone to dampness.
 
It will dry out underneath the plasterboard, might stop it warping out of shape if put up dampish. leave that out on a sunny day and it could twist to buggery.

out of curiosity, what did you pay for that rubbish ? it looks like home grown stuff that has been let by evryone else.
 
Mould can be injurious to someones health but like everything it all depends on the type of mould and resistance of the individual (s), google mould and make your own informed decision, personally I've demolished a asbestos garage with a lump hammer at 33 and at 70 still here to tell the tale but next year who knows!!

I find that if you get it up sharpish and board it quickly it will dry out sufficiently without warping, however leave it hanging lying around outside to dry out, or put the frames up and leave them a week or two to dry out and all those knots will guarantee it will warp
