Good afternoon, 

 

We receintly had our FSSC stage 1 audit and was asked for validation for our identified CCP Produce sanitation.   We are a catering facility and because many produce is eaten raw we have identified the sanitation procedure as a CCP. 

 

Problem is the Salad wash tablets containing Sodium dichloroisocyanurate only comes with SAfety data sheets,  Does anyone one have any helpful studies or references I can use for validation ?

You need to find a way to test for the amount of "free or available" chlorine regardless of the forum you're using it in. you'll need a titration kit or dip sticks to check the ppm of chlorine in your wash water

 

Validation studies won't work because the water you're using isn't the exact same chemistry and neither is the source of the chlorine


Because we always have is never an appropriate response!

Thank you for your comment. 

 

We do test the solution with Chlorine strips, this is according to the auditor not sufficient. 

 

We need to provide studies to show the effect  Chlorine has  on pathogens and contact times , the strips are just a verification that we are using it at the right dilution.   

 

I have found some articles but nothing really great, thought I would try my luck here to see if someone might have come across a good one. 

 

Thanks again
