Introduction: The aim of this study was to evaluate the prevalence of Clostridium botulinum and Clostridium perfringens in food samples purchased from Polish producers. Material and Methods: The analyses were performed on 260 food samples collected in Lublin and Subcarpathian regions: 56 of smoked meat, 21 of pork meat, 20 of dairy products, 26 of vegetable and fruit preserves, 40 of ready-to-eat meals, 27 of fish preserves, and 70 of honey collected directly from apiaries. Results: C. botulinum strains were isolated from 2.3% (6/260) of samples and the isolates were classified as toxin types A (4/260) and B (2/260). C. perfringens strains were isolated from 14% (37/260) of samples. All the isolates were classified as toxin type A, 28 of them were able also to produce α toxin and 9 - β2 toxin. Conclusion: On the basis of the obtained results it could be suggested that risk assessment, especially regarding the entire honey harvesting process, should be provided in order to ensure the microbiological safety of the products to be consumed by infants and people with a weakened immune system.

The objective of this study was to assess the extent of parasitological contamination of soil irrigated with wastewater. Samples were randomly collected including soil, and water samples from which soils were watered. Samples were taken from different locations in Sharkia governorate, in the east of Nile Delta, Egypt. Such locations were irrigated from water canals, namely El-Ganabia, Sherwida, El-mahmodyia, El-Senety, and Saft Zerek. The samples were collected monthly during September 2021 to September 2022. More than half of the collected samples (60.7%) tested significantly positive for parasite contamination. The largest proportion of pollution was found in areas near the El-Senety Canal with a rate of infection (80%), whereas soil samples near the Moias Canal area had significantly the lowest (40%). 40.8% of positive samples had one parasite species, whereas 37.9% and 11.5% of positive samples were infected with parasites.

Objective-To assess dual-energy x-ray absorptiometry (DXA) for evaluating effects of diet and environment on bone mineral density in Hermann's tortoises (Testudo hermanni). Animals-26 Hermann's tortoises within 1 month after hatching. Procedures-Group 1 was housed in an artificial setting and fed naturally growing vegetation. Group 2 was housed in an artificial setting and fed vegetables grown for human consumption. Group 3 was maintained in an outside enclosure and fed naturally growing vegetation. After 10 months, pyramidal growth, body weight, and adverse conditions were assessed. Bone mineral density (BMD) of the axial and appendicular skeleton, shell, vertebral column, and pelvis was measured via DXA. Results-Group 2 had the highest mean +/- SD body weight (65.42 +/- 30.85 g), followed by group 1 (51.08 +/- 22.92 g) and group 3 (35.74 +/- 7.13 g). Mean BMD of the shell varied significantly among groups (group 1, 0.05 +/- 0.03 g/cm2•m; group 2, 0.09 +/- 0.15 g/cm2•m; and group 3, undetectable). The BMD of the axial and appendicular skeleton, vertebral column, and pelvis did not differ significantly among groups. Pyramidal growth was highest in group 1 and not evident in group 3. Conclusions and Clinical Relevance-Tortoises raised in artificial conditions did not have deficits in BMD, compared with results for outdoor-housed hibernating tortoises. Supplemental calcium was apparently not necessary when an adequate photothermal habitat and plant-based diet were provided. Higher BMD of captive-raised tortoises was morphologically associated with a higher incidence of pyramidal growth in captive-raised groups.

Out of73 washing samples from commonly used vegetable viz. dhania (14), coriander (Coriandrum sativum) (12), pudina (11), spinach (Spinacia oleracea) (9), carrot (15) and raddish (12) collected either from local vegetable markets or residences, only 2 carrot washings and one radish washing were found positive for strongyle ova and one dhania sample was positive for ascarid ova.
