Cross-contamination of food: a major risk that can be prevented
Well known to professionals in the food industry, this type of contamination affects all product categories and poses a threat to food safety. Fortunately, it is possible to prevent cross-contamination of food. Photoclean, the only company in France entirely dedicated to air decontamination, explains how.
What is cross-contamination?
This refers to food contamination caused by the unintentional transfer of undesirable substances onto food products. These substances may include microorganisms—molds, yeasts, bacteria, and viruses—as well as chemical contaminants or allergens.
Cross-contamination canoriginate from another food item, a contaminated surface, a person, or even the ambient air. Two scenarios are frequently observed:
- Contamination from one food product to another during manufacturing or packaging: for example, a cheese is packaged, and the mold responsible for its characteristic flavor contaminates another type of cheese that is packaged afterward.
- Contamination via storage containers: Residues from a contaminated food spread to other foods stored in the same container.
What are the risks of food contamination?
The health risk associated with cross-contamination is real, particularly for people with allergies or those with compromised immune systems. Exposure to an allergen, even in minute amounts, can cause severe reactions. As for the presence of pathogenic microorganisms, such as E. coli, Salmonella, or Listeria, they cause serious cases of food poisoning.
The food industry is particularly vulnerable to the risk of cross-contamination, especially between different products.
How can you prevent cross-contamination of food?
In any production or processing facility, it is essential to separate preparation areas and ensure effective surface disinfection. But that’s not all: preventing cross-contamination of food also requires air sanitation.
Here is an example of cross-contamination prevention in the food industry:
- A processing facility handles leeks and onions, two products that can transfer contaminants—particularly molecular contaminants (VOCs and odors)—to other products.
- The company turned to Photoclean because vegetables had been contaminated following preparation in the same area.
- After inspecting the facilities, Photoclean recommends a decontamination solution that involves extracting and purifying the air between two batches of produce.
- Airborne contaminants are eliminated, thereby preventing any cross-contamination between the two products.
Air treatment in the food processing industry plays a critical role in preventing cross-contamination. In fact, ambient air can transmit various contaminants from one product to another.
What does the Photoclean air decontamination solution involve?
Air quality is essential for ensuring food safety and preventing product recalls. Photoclean, an expert in industrial air treatment, has developed an exclusive solution. This solution is based on the natural ability of UV-C rays to destroy microorganisms and chemical contaminants. Combined with a specialized medium patented by Photoclean, these rays are integrated into compact and highly efficient air decontamination modules.
Photoclean products are available in several versions: standalone units, purification modules adaptable to any existing air handling unit (AHU), or AHUs with an integrated decontamination module. This provides you with a turnkey solution that allows you to decontaminate very large volumes of air in a less cumbersome and more cost-effective manner than with traditional techniques.
