Hi all, finding this website really useful!  Thought I would just throw this one out there as I have looked but have not found confirmation that I am fully satisfied with.  A count of 40 cfu/g for Bacillus cereus on a raw ingredient, is this still ok?  I have checked but everything I have looked at is for finished product and it is within spec for that.  My hesitation is that it is a raw ingredient that will be used in a product that is not really going to be going through any major heat treatment.

 

All advice appreciated!! :)

Dear waferthin,

 

Raw ingredient = ? (it can be relevant), and to be used for ?

The presence of large numbers of B. cereus (greater than 10^6 organisms/g) in a food is indicative of active growth and proliferation of the organism and is consistent with a potential hazard to health.

 

So your count of 40/g is not high, you need to consider how the ingredient will be used by your customers, the potential for growth and agree an acceptable specification.

 

I assume that you prescribe storage conditions/shelf life and already determine the extent of growth during this time.

 

Regards,

 

Tony

Dear Waferthin,

 

No direct experience with albumen however I did a little googling.

Most micro. specs for albumen seem to not include B.cereus. Could only find one –

 

Attached File  specification - EGG_ALBUMEN_POWDER.pdf   151.9KB   13 downloads

 

As per above, yr result is on the borderline however this spec. seems pretty tight to me compared to most RTE product data I could see (the quoted S.aureus limit is a bit odd also).

 

I presume this product is heat treated. I noted that B.cereus normally survives the pasteurization process used for egg products.

 

I  guess the situation  somewhat depends on yr finished product spec and the related process as per Tony.

 

The HPA (ca. 2009) regard  10^3-10^5 as borderline (previously PHLS [2000] considered  >10^4/g as unsatisfactory) in the various RTE products covered.

 

Is yr final product spec. < 100/g or ?? Do you only have one datum (micro. measurements usually have large confidence intervals).

Kind Regards,

 

Charles.C

Hi,

 

Thank you both for your help.  The product is not currently being manufactured as it is a seasonal product.  It is mallow eggs which do go through

some heat treatment during the process and only have a 3 month shelf-life.  As we are not using it at present I will have it tested again just prior to its use to ensure its safety.  We normally do not have an issue with albumen which is why the result through us a bit.

 

Thanks again!
