Yeast & Mould, Total Plate Count
Dear All,
I, Sushil Jagtap, Buyer in one of the Food Company. It is a pleasure to be here with you. I would like to know get information on practical ground from the experts like you all.
I have come across on situation where there is material failing in Yeast & Mould . Limit 100 CFU/GM and observation is 200 CFU/GM.
Request you to share your experience that in this case " Should we reject the material?"

Hi Sushil,
I assume this is the result for one sample on an isolated lot.
This is normally regarded as an inadequate Sampling Plan for applying an accept/reject microbiological decision for a non-zero tolerant characteristic.
Suggest a generic format something like this but it might depend on the actual product -

Agree with Charles, regardless of the product you're making, the decision whether to accept or reject a lot based on a quantitative value requires more than one sample for it to have any sort of significance.
The fact that you're reporting a result of 200 makes me think that this test was performed using a 10^-2 dilution, which would be inappropriate when your established limit is 100 cfu/g. What is the testing method that was performed?
Micro limits don't mean anything without context. To evaluate whether you should accept or reject the lot, you need the following information:
1. Is the product supposed to be commercially sterile or otherwise free of organisms?
2. What is the product?
3. What food safety hazard would be represented by a high yeast&mold count?
