Hi all,
There was complaint in cream and when we did yeast and mould testing, then orange colour colonies of yeast and black mould is detected.
Kindly help what colonies it could be and how can I confirm it apart from Microscopy?

I have more questions to ask you than you are asking
Anyway, these are typical characteristics (orange yeast, black mold) of Y/M. Your lab should be able to identify.
Was it over the limit? Did you have the product tested prior to receiving complaint? Was storage condition maintained throughout?

The sample was passed before.
The count is over the limit now. And the conditions we are not sure of as the complaint has come from single sample from someone's home.

So, a customer opened your product and found it to be moldy?

I dont believe you can identify or speciate yeast with a microscope. This is typically done using phenotype and / or genotype testing.
Molds can be somewhat identified using miscropically. However, one needs to have knowledge of the practice.
In both cases, I think you need to send the organisms to an expert for identification if that is what you are wishing to accomplish.
If your inhouse tests do not indicate an issue over the shelf life, I'm not sure what else you can do. If you have an in house issue, you just need to find and eliminate the issue. Doesnt really matter what the organisms are. They need to be eliminated or reduced to an acceptable level.
