In small quantities I wouldn't think so, otherwise we're all tapped since killing small bits of this and that is what its for to begin with. Did it just get into a batch you had mixed up or did it somehow get into your concentrate? If in a batch, and much got in at all, I'd still recommend tossing it and starting fresh. Effective or not you still don't want to be transferring ick to freshly cleaned vessels.
