“…Electrospun fibers possess exclusive properties including an ultrafine diameter, a large surface area to volume ratio, a high aspect ratio of length to diameter, better porosity, good mechanical strength and processability, and low cost. These overwhelming advantages have attracted researchers to explore the usage of electrospun fibers for different applications in industry such as tissue engineering, − filtration, energy, − biotechnology, − sensors, − dielectric materials, and battery separators. The metal/metal oxide incorporated electrospun fibers and conducting electrospun fibers are highly promising for applications in solar cells, fuel cells/batteries and super capacitors, hydrogen storage, sensors, and EMI shielding …”

Advancements in technology and widespread usage of electronic equipment have led to a vast hike in electromagnetic pollution such as electromagnetic interference (EMI). This has resulted in major concerns regarding human health and improper functioning of electronic devices. Therefore, high-performance EMI shielding materials are necessary to ensure human well-being and protect systems in domestic, civil, or military applications. Earlier, metals and alloys of metals served as EMI shielding materials. But due to their heavy weight, low corrosion resistance, and advancements in miniaturization of electronic devices, currently, metals have only restricted applications in EMI shielding. Thus, flexible, lightweight, and high-performance EMI shielding materials assume great significance. Polymer composites have emerged as a better alternative to EMI shielding materials because of their light weight, corrosion resistance, and ease of fabrication. This article reviews the important literature on electrospun polymer composite fibers for EMI shielding applications. Fabrication methods and different types of fillers and their influence on EMI shielding properties are discussed in detail. The article tries to highlight the huge potential of the electrospinning technique toward the development of specialty materials for EMI shielding.

Salmonella spp. prevails as the main cause of raw meat foodborne illnesses. Implementation of food safety management systems such as Hazard Analysis and Critical Control Points in swine abattoirs can help to mitigate pathogen exposure. The objective of the present study was to evaluate the impact of the HACCP system in slaughterhouses in Colombia on reducing Salmonella spp. exposure due to the consumption of fresh pork meat. Two slaughtering plants with a different degree of HACCP implementation were selected and a quantitative microbiological mapping was built by collecting 820 samples of Salmonella spp. enumeration at different processing stages. The overall Salmonella spp. mean concentration was 1.15 ± 0.55 log MPN/g, with no significant differences among plants ( P > 0.05). Deficiencies during carcass disinfection and temperature during distribution of meat cuts from the slaughterhouse lacking of HACCP resulted in a significant increase of Salmonella spp. prevalence (20–40%) ( P < 0.05). Processing stages with the highest pathogen prevalence were transport (28–32%) and hanging (16–36%). The exposure assessment model estimated a higher degree of pathogen contamination at the time of consumption in meat cuts from the slaughterhouse without HACCP (3.36 versus 3.68 log MPN/g) and 10-fold increase in the probability a consumer would acquire a contaminated portion (0.011 versus 0.105). Implementation of the HACCP system in swine slaughterhouses represents tangible Salmonella spp. reduction control and public health protection measures.
