Please help me save my raspberries!

[Isitbedtimesoon]

We've just moved house and for the past few weeks excitedly watched raspberries ripen on a heap of old bushes at the bottom of the garden.

But, a lot of them are marked. Is this the Botrytis I read about on Google or something else? (Pictures attached)

They are all crammed in together at the bottom of a very overgrown garden so need a good tidy up and maybe staking, but the leaves all look fine.

I suppose my main question is can I eat the ones that look okay? And the ones that only have a slight mark, can I do anything to make these safe to eat. Hoping I don't have to bin the lot :(

Thank you

Ooh it could be
Could you have a good tidy up, and remove all dead stuff round and about the rasps, the hopefully the next lot will be ok?

If the plants are old, there might be lots of previous years' canes that you can cut out? Any dead or brown canes, just cut them right to the floor.
