Meat processing

During the manufacturing process at this meat processing facility, cooked meat exited the oven and passed through a cooling tunnel, where sterile air was used to lower its temperature before packaging. Upon disassembling the internal components of the air vent and inspecting the area behind it, Listeria was discovered on the bottom and sides of the unit. This indicates that during processing, contaminated air from the vent may have carried Listeria into the cooling tunnel, potentially exposing the meat to contamination.

Tijdens een hotelverblijf onderzochten we de hygiëne in zowel de badkamer als de hotelkamer zelf. Hoewel foto’s een ogenschijnlijk schone en badkamer lieten zien, toonde inspectie met een Bioglo lamp verborgen bacteriële verontreiniging aan, met name in de directe omgeving van de wastafel en het bad. De detectielamp bracht duidelijk naar voren waar de schoonmaakprocessen tekortschoten, en schimmelvorming op het plafond werd onder UV-licht direct zichtbaar.

The video shows a pressure gauge and DIN fitting equipped with a rubber seal, which had become perforated, allowing high-pressure air and product to escape, contaminating the external environment and contributing to biofilm formation. When the system pressure dropped, air and contaminated product were drawn back through the damaged seal, leading to contamination of the entire product pipeline.

Food industry

ATP testing cannot reliably detect biofilm, as the swabbing process is limited and typically targets only visible or assumed food-contact surfaces. As this video demonstrates, food handlers often touch surfaces under countertops (such as the undersides of tables), leaving smudge marks that can become breeding grounds for biofilm formation. These overlooked contact points can lead to cross-contamination and the spread of pathogens.
