Depends on your process, types of surfaces, equipment, etc. I generally like to use 2 different sanitizers, one alcohol based and one quaternary ammonia. Have used sodium hypochlorite as well however will pit any aluminum it comes into contact with so there is an appropriation that needs to occur. My usage was in a dry bakery and now in a confectionary process which both were/are dry cleaned. Been down the kosher road with all 3 types mentioned with no issues. Organic will require residue testing as part of pre-op inspections specifically in quat sanitizers and your certifier can provide the information needed on approved sanitizers so other than the call out to the inter-webs, I would also reach out to the them. You will have to get this on an approved status anyways so always the best start with the certifier.
