I took some prawns out of the freezer...

I took some uncooked fish and uncooked prawns out of the freezer this afternoon to defrost on the side, with the intention to cook them tonight.
However plans have changed and I won't be cooking them until lunchtime tomorrow. I've just put them in the fridge - they are defrosted but cold - I'm not going to give anyone food poisoning with them, am I?

If they are still very cold & you've put them in the fridge they should be fine tomorrow. I wouldn't leave them any longer, though.

Yes, they were cold so hopefully all ok, many thanks for your response.
