An average of over 20 food manufacturers each year issue recalls due to Listeria alone (FDA, 2018). Recalls are costly and potentially devastating. Bacteria like E. coli, Salmonella, Listeria, and Shigella can harm consumers and put manufacturers at risk of shut down for re-validation.
Because oil and water contamination, and lack of preventative maintenance on air distribution systems all act to create an ideal habitat for microorganisms, it’s important to employ proper dryers and filtration. Point-of-use filtration helps to protect the product from any contamination in the air system. However, anything from routine maintenance, to a leak, to an inadequate filter can allow for dangerous contamination to enter the system. Regular testing is critical to ensure that the system is functioning properly.
Since warm, dark, and moist environments are ideal for microbial growth, it is important to keep your compressed air clean and dry. Find more information on testing for particles, water, and oil here.
