Exploration of the fipronil in egg contamination incident in the Netherlands using the Functional Resonance Analysis Method

Rounaq Nayak et al.

Summary: After the 2017 fipronil egg contamination incident in the European Union, ongoing improvements in safety management are necessary, particularly in regulatory, preventive, and control activities. This study uses the Functional Resonance Analysis Method (FRAM) to explore the regulatory framing of eliminating red mites on poultry farms, and examines the gap between policy directives and actual practices. The analysis suggests that high level policy makers need to understand the challenges faced by implementers, as policy in practice may not align with intentions.

On the future of the giant South American river turtle Podocnemis expansa

German Forero-Medina et al.

Summary: Conservation efforts for the South American river turtle Podocnemis expansa started in the 1960s, but uncertainties remain around population trends and the number of nesting females protected. Over 85 conservation programmes in Brazil are protecting 147,000 nesting females, with the top six sites harboring over 100,000 females and being prioritized for conservation action. More data and global conservation efforts are needed to address the historical population decline and ensure the species' survival.

Assessing single effects of sugarcane pesticides fipronil and 2,4-D on plants and soil organisms

Maria Carolina Triques et al.

Summary: Pesticides have negative effects on non-target species, especially dicot plants; herbicide has the greatest impact on radish, while insecticide affects Folsomia candida the most. Despite the same sensitivity order of organisms in both soils, the extent of effects varies depending on soil types.

Determination of fipronil and its metabolites in egg samples by UHPLC coupled with Q-Exactive high resolution mass spectrometry after magnetic solid-phase extraction

Yan Zhao et al.

Summary: A novel MSPE method combined with UHPLC-Q-Exactive HRMS was proposed for determination of fipronil and its metabolites in egg samples, utilizing Fe3O4@nSiO(2)@mSiO(2)-PDA as the adsorbent. The method showed good linearity, high sensitivity, adequate recovery, and repeatability, and was successfully applied for determination of fipronil and its metabolites in egg samples.

Avian Eggshell Membrane as a Novel Biomaterial: A Review

Yaning Shi et al.

Summary: The eggshell membrane (ESM), made mainly of collagen-like proteins, is a novel biomaterial with potential applications in nutraceutical, cosmetic, and pharmaceutical fields. This review discusses the structure, chemical composition, isolation methods of ESM, as well as the role and performance of ESM-derived products in various applications. Safety evaluation of ESM and its potential in different engineering fields are also highlighted for future directions and applications.
