Can copper sulphate in food damage invertebrates

[LxHowler]

So I might be missing something but I thought copper was bad for inverts.
I have just bought a new tub of vitalis marine pellets and noticed one of the ingredients listed is copper sulphate. Is this not going to be bad if one of my shrimps tries to eat it. I'm sure it's safe else they wouldn't sell it but I was curious if it would cause issues. My old tub doesn't seem to have it in but that's the old recipe

Copper is a critical element for most organisms at some level, and is a poison at other levels.

Presumably manufacturers put in a useful rather than a toxic amount.

Thought that might be the case. I didn't think they'd put anything dangerous in it I was just curious as to if I needed to be careful about inverts eating it
