Hello,

 

We are conducting cleaning validation and we have 3 risks: allergen, bacterias, chemicals.

 

The methods of analysis that we will follow for Allergen is Elisa and but we don't know what to use for the other risks (chemical and microbiological).

 

Based in the analysis of the food surface contact there is no pathogens (salmonella, E.coli, Listeria) but we have moulds yeasts, enterobacteriae.

 

For chemicals the mains issue is the cleaning product that could remain after cleaning.

 

How to validate that the cleaning is efficient and there is no traces of detergents?

 

Could we consider lubricant also as a risk and we should remove it after the cleaning? all our lubricants are food contact

 

 

 

Thanks

Hi

 

you can use ATP test

 

What is an ATP Hygiena swab? | ATP Hygiene Monitoring |

It's acceptable for the validation?

 

i think that only the quantitaive test methods can be used for the validation of the cleaning

 

ATP is for verification

Your micro could easily be completed through various rapid methods, the easiest being a product like Petrifilm. Indicators like EB's and APC's in addition to your Rapid Yeast/Mold (RYM) petrifilm would be adequate. If this is not as robust as you would like, maybe run traditional PCR or LAMP technologies in addition to the plating.

Most commercial chemical supply companies will also sell kits or strips to verify or validate your cleaning procedures, often by detecting trace residue of the active ingredients in the detergent or sanitizer.
