Fluoroquinolones are a valuable synthetic antibacterial class widely used in the treatment of infectious diseases both in humans and animals. Until recently, it has been thought that bacterial resistance to fluoroquinolones develops very slowly. Nowadays, there are multiple studies that reveal the alarming occurrence of bacterial resistance and there is a high risk of becoming therapeutically useless. The emergence of this phenomenon comes from injudicious usage in therapy, the presence of residues and their metabolites in food of animal origin and also in sewage, compost and domestic waste, which end up in soil and water sources. In the present paper, we reviewed important issues regarding fluoroquinolones impact on the environment in connection with the development of bacterial resistance: (1) the presence of fluoroquinolones as pollutants in soil, surface waters, and food. Fluoroquinolones are persistent with high specificity to interact with soil compared to other antibiotics. Pollution of water sources raises concerns regarding the effects of small concentrations (ng L⁻¹) on human health and also of the environment. The non-therapeutic use in animal farms conducts to food pollution; the cultivated plants could concentrate the fluoroquinolones (over 100 μg L⁻¹); (2) the increase of bacterial resistance to fluoroquinolones occurring with specific mutations in the target enzymes as well by the plasmid-mediated resistance and active efflux of the cell; (3) international regulations of the fluoroquinolone residues in food that are far to encompass all compounds; (4) fluoroquinolones residues analysis with standardized methods should provide limits of detection lower than maximum residue limit values; and (5) trends and perspectives: (a) a wider process of harmonization of regulations; (b) the fluoroquinolones restriction, necessary for low levels of bacterial resistance; (c) the soil and waste water purification methods; (d) the practice of soil planting scheme as an alternative; and (e) an environmental label in order to facilitate the selection of drugs.

Correct identifications are the key to all data on an organism. Fungi cultured or sequenced from a foodstuff may not always be the spoilage agents, and there are potential pit-falls in culturing and molecular identification. Molecular phylogenetics is resulting in major changes in fungal classification, and substantial changes in the rules on naming fungi were agreed in 2011. Different morphs of a single pleomorphic species can no longer have different scientific names, and stability is to be fostered through lists of protected names. The naming of fungi is becoming increasingly fit-for-purpose by taking advantage of the possibilities arising from advances in molecular and digital technologies. A list of the current names of 100 species of spoilage fungi is included.

This article provides a review of trade-offs and synergies of bioenergy within the water–energy–food security nexus, with emphasis on developing countries. It explores the links of bioenergy with food security, poverty reduction, environmental sustainability, health, and gender equity. It concludes that applying the nexus perspective to analyses of bioenergy widens the scope for achieving multiple-win outcomes along the above aspects.

This paper combines Food and Agriculture Organization (FAO) Food Balance data with Water Footprint data to reveal how virtual water flows interact with food import tonnages to enhance or retard national decoupling based on food trade. Decoupling theorises breaking the links between economic and population growth and water demands for domestic food production. The detailed analysis applies a resource decoupling model in relation to the role and potential of food and virtual water trade in alleviating national and regional water limits in the Middle East and North Africa (MENA). The contrast between Egypt’s political denial of dependence, and Israel’s strategic adoption of food imports provides an example.

Bird feeding in residential gardens is an increasingly popular human–wildlife interaction. In Australia, the practice is discouraged by most government and nongovernment wildlife conservation agencies, although advice varies and the most common recommendation is to provide water and habitat for birds rather than supplementary food. This study compares bird abundance and diversity when residents in a Melbourne municipality provide water for birds versus food. Bird abundance was greater when food was provided compared with water, but avian assemblages did not differ.
