Dear all,

could anyone offer up suggestions/experiences regarding a tolerance level when conducting a Mass Balance for a BRC Food Safety Recall/withdrawal.

When dealing with 100's of tonnes of wheat with stocks visually estimated by experienced operatives it still leaves an element of 'guess work' and it's difficult to trace the full 100% of the grain.

Is there an accepted industry standard for a tolerance level?

If not......is there an accepted 'formula' we can follow to calculate what is an acceptable % that cannot be traced?

 

Thank you

Dear 
it is very unlikely that the mass balance check  will be 100% accurate however the fundamental part is to able to demonstrate that the mass Balance is achievable.
I recently conducted a mass balance exercise and there was a large amount of loss that could not be reconciled. to improve the process. production records had to be redesigned to included waste.
it also  depending on all records available.I  might attached  a template that we use during our production records with end waste if that will help.

Regards

Dear Dawny,

 

BRC has no guidelines or some quantified given standard. This attachment was the used during our BRC7 audit.

 

Recovery is 99.5 to 105%.

Hi,

 

A mass balance is really trying to assess is if there are any discrepancies in your traceability systems, and is a very good way of showing this.

 

For example, if you have used 100 Kg of raw materials and 1000 donut cartons, you should through your traceability system (paper based or not) show that all of these have been accounted for, and none have gone 'missing' (i.e. not been recorded correctly).

 

The mass balance should also show waste (both measurable, and also the usual 'spillages' based on historical data).

 

Mass balances should really show at least a 95% accountability.
