Usually growth is at 20-25 or even 25-30. But alternative parameters will need to be validated to give equivalent results as using 20-25 with an appropriate medium. 

Some companies have validated a single medium (e.g., TSA) at a single temperature or dual temperatures instead of using TSA and SDA. But again, they would have validated the change using a panel or challenge organisms and in many cases, side by side testing in areas that normally provide recoverable counts.

    Good afternoon all,
    
    Am scouring the regs for an answer and haven’t come up with anything.  For EM testing of yeasts and molds, is it ever acceptable to only incubate plates at 30-35, regardless of the selectivity of the media used in the sampling?  In my previous experience, growing fungi occurs best at 20-25, regardless of media type, and have heard of large aseptic manufacturers get cited for only incubating at 30-35, and being required to rethink their incubation plan.
    
    Kind Regards,
