Without effective air filtration, food and beverages can become contaminated due to poor air quality.
Most people understand that air pollution and poor air quality are issues that are important, but it often remains an abstract concept until it affects them directly. But food and beverage contamination grabs people’s attention, because eating and drinking is a vital and necessary part of everyone’s day. Understanding how airborne particulates can compromise the quality of food and drink is the first step in understanding how air filtration systems can provide a solution.
“The food and beverage industry has a big challenge when it comes to protecting their employees and their processes from harmful air pollutants,” stated Mark Davidson, Food and Beverage Segment Manager. Unlike other industries, an E. coli outbreak or a Salmonella outbreak from one shipment of food can cause havoc for months and years. It can destroy a company’s reputation, and worse yet, it can permanently dent the trust that consumers place in that company’s ability to deliver food that is not tainted. For those reasons, effective air filtration systems are essential to the survival of food and beverage companies.”
How Contamination Occurs
Food and beverage contamination can occur in several different ways during processes such as packaging, sampling, production, storage and transport.
However, per an article in Nutritional Outlook magazine, there are three main types of contamination that typically affect the food and beverage industry: Cross-contamination, particle contamination and microbial contamination.
During the production process, cross-contamination occurs when more than one type of food is produced at a facility, and equipment used to process that food is not properly cleaned. As a result, contamination from one type of food is transferred to another type of food due to the improperly cleaned equipment.
For the purposes of air filtration, however, particle contamination and microbial contamination are far more relevant to the issue at hand.
Particle contamination occurs when tiny airborne particles settle into food and open beverage containers during the production process, or during the packaging process.
This type of contamination is nearly always due to a lack of effective air filtration system that can eliminate many of the particulates before they land and mix into the food. But in addition to air filters, food and beverage facilities must also understand how the construction and design of their facilities may hinder or help the incubation of harmful particulates.
The third type of contamination – microbial contamination – refers to the growth of bacteria and mold.
Microbial contamination can occur due to improper sanitation procedures by employees, or through moisture in the facility from leaks that can worsen over time and lead to mold. Many bacteria and mold can become airborne and if not removed by effective air filtration can become a liability.
The Importance of Filtration and Facility Design
Combating food and beverage contamination at these facilities typically comes down to implementing an air filtration strategy as well as optimizing the design of a facility.
High efficiency particulate arrestance (HEPA) air filters are rated to eliminate 99.97 percent of particles that are 0.3 microns in diameter, which is about 300 times smaller than strand of human hair, and far smaller than the human eye can perceive.
HEPA filters are so effective that even the Centers for Disease Control (CDC) Guidelines for Environmental Infection Control in Healthcare Facilities recommend their use to trap microbial spores in patient rooms.
This makes them ideal for eliminating microbial contamination in food and beverage facilities. However, even the best air filtration system cannot be fully effective without an adequate ventilation system, which considers humidity and temperature, and the amount of fresh air circulating through the facility.
