Cutting airborne contamination at food production facilities

This form of contamination is particularly insidious because it can happen at almost any stage of food and beverage processing. It’s hard to detect, so prevention is crucial. Even when taking common-sense precautions, food dust particles can easily spread between products. These particles, which vary in size and can be invisible to the naked eye, often include dust from grains, cereals, eggshells, or shellfish, and powders such as spices, sugar, corn starch, and flour.

Non-food particles such as dirt, dust, and bacterial spores, can enter the food production facility and come in contact with the product. It is common to see particle contamination during production or packaging. In addition to risking contamination, other hazards of airborne contamination can include poor employee health and more frequent breakdowns with machinery.

As the name suggests, this involves microbes such as bacteria and mould spores, contaminating the product. Microbial contamination occurs most frequently when employees handle the product. Workers who fail to use appropriate protective gear or maintain personal hygiene pose the largest risk.

Regular testing can identify airborne contamination early and allow the facility to find and resolve the problem quickly. Food production facilities can run testing on incoming ingredients, production components, and finished batches of product to ensure no contamination has taken place. These organizations should also establish specifications for every step of the food production process, so that test results have a meaningful benchmark to measure against.

The design of the food production facility is also important to reducing the risk of contamination. Facilities that lack drainage or restrict airflow can cause particulate matter to spread, as can inappropriate temperature and pressure management. It’s also important that surfaces are smooth and simple to clean, so they don’t accumulate dust. The facility should have distinct areas for each area of production – particularly if it is working on multiple products simultaneously – to limit the potential for cross-contamination.

Finally, making use of air purification systems is a high effective and affordable solution. At Zehnder Clean Air Solutions, our filtration systems can prevent dust, bacteria and other forms of airborne contamination from settling on sensitive goods. Because our air purifiers capture dust at the source, they ensure that the particles do not get a chance to circulate through the air and contaminate products. They can also help your company meet regulatory requirements, lower maintenance costs for machinery, and improve employee health, so there are plenty of reasons to consider air filtration today.
