Hi, I am the QA Manager in a confectionery manufacturing company and by a stroke of luck, I fell onto this site a couple of years ago and use it quite frequently to find alot of great advise and information from some wonderful and very knowledgeable people, whom I have to say I am very thankful for. You guys have helped me survive several hard audits and I am getting ready to face another one soon. So I'm turning to you once more with a new area I don't have any idea about. I am new to all this environmental testing and we are trying to be compliant and also want to make sure our product is as safe as we can make it. I am not sure how to go about testing our air. I have ordered the agar plates but i'm not quite sure what the procedure is to use them. Do you have any guidance I can use? Thank you in advance for your help!
