Air monitoring, high values

Hello, our company manufactures fruits and vegetable juices from fresh ingredients. I recently did air monitoring on the different rooms we have to have an idea on where we are right now on values. I was surprised to see that our cold storage room and processing room have high values on Yeast and Mold (more than 2200 cfu/plate). I used an air sampler supplied by the lab and run it for 5 minutes. I don't think those values are normal but I'm not sure how to bring those down. Some of our produce comes straight from the farms so I understand the micro load on those can be high. Could that be the reason? Any ideas on what my corrective action should be? Thank you everyone for your input!

I'd be keying in on the exact reason you just mentioned, farm direct.

Hi lff,

More data is required, eg -

Plate agar = ?

Plate Procedure = ?

No. of Plates / results = ?

Time plate is exposed = ?

location plates = ?

Are your evap coils and condensate pans on a cleaning schedule?  You can also treat the coils with a dosing of chlorine dioxide in between regular cleaning to control plate count, yeast, and molds.
