Listeria monocytogenes is a major concern for the meat processing industry because many listeriosis outbreaks have been linked to meat product consumption. The aim of this study was to elucidate L. monocytogenes diversity and distribution across different Spanish meat processing plants. L. monocytogenes isolates (N = 106) collected from food contact surfaces of meat processing plants and meat p...

Staphylococcus aureus contamination of food and contact surfaces is a public health concern given its virulent antimicrobial-resistant properties worldwide. In this study, total 181 MSSA isolates were analyzed for SE genes, antimicrobial resistance patterns, spa types. Overall, 24.9% positive gene detection, with sea being the most prevalent classical (18.8%). The predominant sample sources han...

We present a nanostructured "super surface" fabricated using a simple recipe based on deep reactive ion etching of a silicon wafer. The topography of the surface is inspired by the surface topographical features of dragonfly wings. The super surface is comprised of nanopillars 4 μm in height and 220 nm in diameter with random inter-pillar spacing. The surface exhibited superhydrophobicity with ...

SARS-CoV-2, a novel Coronavirus that causes COVID-19 disease and the World Health Organization (WHO) declared as pandemic on March 11, 2020. Until now, foodborne or waterborne exposure to this virus has not been reported transmission route. However, infected individual in food production service facility and, contaminated surfaces, may serve source of route since can survive inanimate surfaces....

Listeria monocytogenes has been repeatedly isolated from foods and food-processing facilities including food contact surfaces such as conveyor belts (CB). CBs are often difficult to clean and require rigorous sanitation programs for decontamination. Ultraviolet (UV) light has exhibited microbicidal properties on food contact surfaces and this study was conducted to determine the efficacy of UV ...

Membrane separation is an important processing technology used for separating food ingredients and fractionating value-added components from food processing byproducts. Long-term performance of polymeric membranes in food protein processing is impeded by the formation of fouled layers on the membrane surface as a result of protein adsorption onto the membrane surface. Surface modification of sy...

The main objective of this study was to investigate the effectiveness ultraviolet light (UV-C) emitting diodes for decontamination stainless steel food contact surfaces. Listeria monocytogenes (ATCC 19115), Escherichia coli 25922), and Salmonella enterica serovar Typhimurium 700720) were chosen as challenge microorganisms. Target microorganisms subjected UV-C dosages 0, 2, 4, 6, 8 mJ cm −2 at a...
