We are manufacturing of tube ice , lately our auditor requested us to have pH n Free Chlorine test on our finished product which is ice. For your information , our main ingredient solely is water, no others is added in . Hence, we felt that checking on microbial level on finished product more crucial than pH and free chlorine. Furthermore, the amount of pH and free chlorine will be gradually reduced along the process, this may causing the results of these two parameters out of spec.
Im really need your valuable input on this, should i go for it (as per auditor recommend) . Thanks in advance
