Count of 40 cfu/g for Bacillus cereus on a raw ingredient, is this ok?
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 ?

Apologies for the lack of detail, it is albumen to be used in confectionary product.
Thanks!

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.

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 –
specification - EGG_ALBUMEN_POWDER.pdf 151.9KB 14 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).

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!
