Looking for some guidance in regards to E.Coli standards for a frozen vegetable product. Not seeing much within CFR. Product has various applications but is sold in its frozen, NRTE state. We are currently using customer specific standards of <10 cfu/g but searching to explore further into any other documented studies/reports. Thanks!

i assume refers to non-pathogenic E.coli.

 

May relate to specific analytical Procedure.

 

May relate to item specifics, eg product, degree of processing.

 

Not a safety hazard from a haccp POV.

 

I predict you can find Literature numbers, variously, between zero and 100 cfu/gram.

 

ICMSF for "unprocessed" material declines to suggest limits due non-justifiability

 

JFI, IIRC, the EC officially sets RTE at 1000 max cfu/gram since regarded as a Process indicator.

This is from a non-binding draft (aren't they all!) guidance for preventative controls for human foods

Hi Scampi,

 

I think the OP was seeking generic E.coli numbers ? (ie not a hazard limit and for NRTE)

[Scampi]

Yep I understand that...........this is ALL the FDA info I could find on e coli (not related to meat/recalls/fresh leafy veg)

 

It would give PP a launchpad at least

[cbyus9918]

Thanks all. Appreciate the feedback!

 

Yes- for generic e.coli, thanks for clarifying.
