Description
Daniela Bermudez-Aguirre, Joseph Uknalis, and Katrina L. Counihan measure, in a 2026 food safety study, the glue-like substances Salmonella bacteria secrete while building biofilms on stainless steel. These films shield the pathogen on food plant surfaces and resist cleaning. Two temperatures, fridge-like cold and body warmth, were compared over fifty hours.
Warmth produced a fast surge of free and film cells within five hours, yet the formal biofilm index ran higher in the cold. Sugars in the slime peaked at fifteen hours in warmth, proteins peaked at a day under both conditions, and loose DNA stayed flat throughout. Microscopy showed three-dimensional warm films laced with fibres and secreted material. The authors say such detail helps design sanitation that actually breaks films down.
