Does any one has an example of how to validate the frequency of a cleaning procedure for trucks?

Please supply some context.

 

Standard  ?

Clause ?

Product  ?

 

A generic response would be that you derive/hypothesise a Procedure (eg - appropriate frequency/methodology/specific test criteria) for satisfactory cleaning then show that yr procedure can achieve the desired objective.

Well, in our plant what we've basically is to determine how long it takes to detect or observe contamination of the trucks. The frequency/ recurrence of such observations informs us on the appropriate schedule for our cleaning programme. The schedule is planned to be at a shorter time than the shortest time it takes to realise a contamination.

Simply put, monitor the equipment (trucks etc.) either by microbiological analysis or physical examination whichever test criteria is applicable to you. Per the results, note the time it takes to detect a non- conforming/ out of specification situation. Determine the schedule to be a time shorter than the time it took to detect the contamination. If you detect contaminations after 24 hours, you may maintain your cleaning schedule to be at 18 hours.

To validate, analysis microbiological results or whatever criteria you choose and see if there are out of specification results within the scheduled time for the cleaning. Revise the schedule appropriately (more frequent cleanings required) if there results is out of specification.

Hi Mabel,

 

Thanks for the above details.

 

I would indeed anticipate that the frequency/degree/procedure of cleaning will significantly relate to the specific "Operation".

 

IMEX with bulk raw seafood, the frequency was trivially simple - total intensive cleaning after discharge of every lot.


Kind Regards,

We transport packaged products and have a frequency of monthly.   All trailers are inspected daily before loading and if there is evidence of spills or other contamination they are pulled from the line up and cleaned before use.  We are BRC certified in Storage and Distribution.

 

Thanks
