The present study aimed to evaluate the quality of fresh sushi in Egypt. Fifty samples of sushi (Salmo salar) were collected from restaurants in Alexandria, Egypt. Paraffin, semi-thin and ultra-thin sections were used for parasitological analysis by light and transmission electron microscopy. Bacteria were isolated by the dilution plate and direct plate methods and identified by a Vitek system. Twenty (40%) of the total examined samples showed microsporidia and helminth metacercariae infections. Histochemical stains showed distinct pinkish-red pyriform microspores embedded in muscular tissue stained with Gram, periodic acid-Schiff (PAS), and Ziehl–Neelsen (ZN) stains. Semi-thin sections showed double membrane xenoma-inducing granulomas containing spores at different developmental stages. Empty sporophorous vesicles and free spores were observed in the electron microscopic images. A bacteriological assay showed forty samples (80%) contaminated with human pathogenic bacteria with the average total bacterial counts ranging from 32 to 526 CFU/g. Four species of human pathogenic bacteria were identified in the examined samples, namely Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, and Serratia plymuthica in 40, 38, 11, and 6 samples, respectively. These constitute the first record of fresh sushi product in Egypt and indicate the potential pathogenicity associated with raw seafood products.

This paper presents the one‐pot reaction synthesis of coordination calcium and strontium compounds [Ca(L)2(H2O)2 1 and Sr(L)2(H2O)2 2] with the 2‐(4‐ chlorophenylamino) benzoic acid ligand (HL = C13H10NO2Cl). The complexes were obtained in good yields, and their structures were corroborated according to their CHN, spectroscopic (IR and UV/Vis.) and solution molar conductivity data as the latter confirmed their molecular nature. Additionally, the powder X‐ray diffraction pattern of the complexes was used to determine the cell parameters and the hkl indices together with their corresponding 2θ values. The microbial resistance against the currently available antifungal agents requires searching for new antifungal compounds. Promising fungicidal activities of these coordination complexes were determined against the Fusarium corn disease as complexes 1 and 2 at 30°C inhibited the grain pathogenicity by 70% and 66%, respectively. Moreover, 1 and 2 retarded the amylase enzymes that are responsible for the pathogenicity by 35.13% and 26.22% at 30°C.
