Thanks Laura - when I first read of this device, what rapidly came to mind was that anything under pressure coming through a tube should be somewhat suspect. You'll all probably laugh, but it's the reason I don't have a water/ice dispenser on my refrigerator door. I kept thinking, "How clean can that be?"
Yet, when I started to do some research for the article, I was amazed at the lack of discussion on this. Thanks for posting!
You make an excellent point Carolyn. At this time there are no requirements that specifically address the testing of compressed air used in pharmaceutical or medical device manufacturing. SQF was the first group to require compressed air testing for food manufacturers in the US and that just began in 2012. Keep in mind that compressed air has been used in manufacturing for decades. Our company is looking forward to adding the CAMTU to our menu of options for the testing of microbiological contaminants. Bravo Parker Balston!
