Abstract:
... Reduction of Salmonella on poultry carcasses is one way to prevent salmonellosis. The purpose of this research was to evaluate the effects of subzero saline chilling (SSC) with/without hot water spray (HWS) on broiler carcasses prior to chilling for bacterial reduction. Eviscerated broiler carcasses were subjected to water immersion chilling (WIC, 0% NaCl/0.5°C) or SSC (4% NaCl/−2.41°C) with/witho ...

... Since bacterial contamination is a significant threat to humans, early detection is essential to safeguard dietary safety and physical health. Here, a nanofiber color indicator film based on poly-l-lactic acid (PLLA) as the support and anthocyanin as the indicator material was prepared by electrostatic spinning. It was found that the PLLA/0.8CY nanofiber color indicator film was hydrophobic (the w ...

Abstract:
... The occurrence of biological contaminants in common beans is a challenge for food safety, as they can affect the bean at different points in the production chain. Their presence can result in damage to the health of consumers through their direct toxic effect or by promoting nutritional deficiencies, in addition to decreasing the crop yield that has an economic impact. In this article, the informa ...
... AIMS: The absence of objectionable micro‐organisms in cosmetics and the efficiency of preservatives are still mainly assessed by time‐consuming cultivation‐based methods. We explored the applicability of real‐time quantitative polymerase chain reaction (qPCR) and reported on the behaviour of different bacteria in artificially contaminated creams. METHODS AND RESULTS: Real‐time qPCR on DNA from Bur ...

Abstract:
... Filtration membranes are widely applied in medical fields. However, these membranes are challenged by bacterial contamination in hospitals, which increases the risk of nosocomial infections. Thus, it is significant to develop antibacterial filtration membranes. In this work, an oxidated dextran (ODex)-based antibacterial coating was designed and constructed on microfiltration (MF) membranes and me ...

Abstract:
... Methods to control microbial contamination in confined livestock facilities are important to the health of both animals and workers. In addition, bacterial contamination is also a food safety issue. The most common disinfection technique employed in livestock facilities is the application of oxidizing agents (e.g., potassium peroxymonosulphate, chlorine, hydrogen peroxide, ozone). However, these t ...

Abstract:
... Thermal processing of packaged fruit and vegetable products is targeted at eliminating microbial contaminants (related to spoilage or pathogenicity) and extending shelf life using microbial inactivation or/and by reducing enzymatic activity in the food. The conventional process of thermal processing involves sterilization (canning and retorting) and pasteurization. The parameters used to design th ...

Abstract:
... In the context of widespread bacterial contamination and the endless emergence of antibiotic-resistant bacteria, more effective ways to control pathogen infection are urgently needed. Phages become potential bactericidal agents due to their bactericidal specificity and not easy resistance to bacteria. But an important factor limiting its development is the lack of phage species. Therefore, the iso ...
