Hi AS NUR
i use a number of different things for environmental monitoring.
The products that i am involved with in manufacturing are suceptiple to spoilage by yeast and moulds, so i used Rose Bengal pour plate, which i leave out for 1 hour, to monitor Y&M levels in our packing rooms.
I also use Nutrient Agar to monitor the air quality, especially around the filling heads, using the same principles (open plates for 1 hour)
Both of these i do weekly, with counts that are greater than 100 on the Y&M resulting in a fogging clean being instigated.
also i do environmental swabbing of plant and environment for listeria (Salmonella isn't a problem for us, but it is in dried products), which we do monthly and are sent away for testing.
Also, we plate out swabs for entro's, Staphs and Bacillus on a monthly basis, in tandem with hand swabs for the operators, to monitor the effectiveness of their hand washing.
hope that helps
