Cephalopoda classes are highly valued for their culinary appeal and nutritional value. However, their perishability necessitates careful handling and optimal storage conditions to maintain their quality. This study aimed to investigate the influence of storage temperature on the quality attributes and sensory properties of five commonly consumed cephalopod types: whole squid, whole squid tubes, octopus, Loligo spp. (squid tubes), and Sepia spp. (cuttlefish tubes) classified in five different species (Loligo vulgaris (European squid), Loligo gahi (Japanese squid), Octopus vulgaris (Octopus), Sepia officinalis (Cuttlefish) and Illex argentinus (Argentine shortfin squid)). Lower temperatures (-23°C) significantly prolonged shelf life, delaying spoilage onset and preserving taste. The product named calamar had the fastest spoilage rate, followed by whole squid and tube squid, while Octopus had the slowest spoilage rate. Appropriate storage practices are vital for ensuring the freshness and palatability of frozen cephalopods.

Every microbial environment starts with an initial contamination from microorganisms present in soil, water, and atmospheric dust. The unique characteristics of each environment ultimately dictate which species or types of associations become dominant. Consequently, microorganisms with high resistance to inhibitory or lethal factors often thrive in food products, on various surfaces, and on machinery and equipment. Bacillus cereus serves as a prime example, widely distributed in nature and considered an opportunistic pathogenic species. Research conducted between 2021 and 2023 focused on several categories of milk powder samples collected from sales networks in Călăraşi County, Ilfov County, and Argeș County. These categories included skimmed milk powder with 1% fat, milk powder with 26% fat, organic milk powder with 26% fat, milk powder for children aged 4-5 years, and of milk powder for infants aged 9-12 months. The analysis of these five products involved two categories of methods: confirmation on MYP agar, blood agar, and real-time PCR testing for the amplification and detection of specific Bacillus cereus DNA. Identification of species within the B. cereus group was conducted using specific tests.

The microstructure of the stomach, intestines, hepatopancreas, kidneys, lungs, reproductive organs, and protein gland of two species of snails (Helix pomatia and Helix aspersa Muller) under the influence of abiotic (climatic) and biotic (parasite) factors was studied. In snails of the first group, the visceral organs had a typical structure. The parenchyma of the hepatopancreas, as the most vulnerable organ, is represented by glandular tubules and the system of excretory ducts that open into the intestinal cavity. Structural changes in the hepatopancreas and gonads were observed in snails of the second group, which were in the state of anabiosis under the influence of dry, hot weather. The helminthic invasion in the snails of the third experimental group caused necrosis of the hepatopancreas and replacement of the parenchyma of the gland with loose connective tissue.

The paper presents data on the identification of the helminth fauna structure of Bufo bufo Linnaeus, 1758 and Bufotes viridis Laurenti, 1768 species, ecaudata amphibian from Bufonidae families, and the determination of its role as bioindicators and as vectors for parasitic agents specific to animals. As result of helminthological investigations during 2013-2023 years, in Bufonidae species 19 helminths species was established. The helminthological research carried out on the species Bufo bufo highlighted the presence of 19 species of helminths, of which the predominant parasitic agents are trematodes which make up 47.4%, nematodes with 31.5%, acanthocephals with 15.8% and monogeneans with 5.3%. In Bufotes viridis species, the presence of 18 species of helminths was established, of which helminth species from the trematode class represent the predominant group with 44.4%, nematodes with 38.9%, acanthocephales with 11.1% and monogeneans with 5.6%. The helminthological researches were carried out depending on the age of the host, the type of habitat and the area. The bioindicator significance of the established parasite species was presented for an ecological assessment of the studied area.

Lameness and claw disorders have still adverse effects on cow’s health and milk production levels in dairy enterprises. The objectives of this investigation were revealing non-genetic factors affecting lameness cases (LC) and estimating 305 daily milk production losses (305 dMYL) due to LC in dairy herds. A total of fifteen study results reported in the scientific journals between 2002 and 2021 were analyzed. The percentage of the non-genetic factors affecting LC were noted as days in milk (DIM; 31.25%), parity (P; 25%), season (S; 9.37), calving season (CS; 9.37) and others (25%).To estimate the effect of herd size (HS) on 305 dMYL, three HS groups were divided (small: ≤500 cows, moderate: 501-1498 cows and big: ≥1499 cows). Thusly, 305 dMYL were calculated to be 630 kg, 377.2 kg and 493.57 kg, respectively. In country level, 305 dMYL were determined to be 494 kg, 408 kg and 398.66 kg for UK, US and other locations, respectively. Finally, the overall mean of 305 dMYL caused by LC was 419.66 kg/cow.

The nutritional quality of poultry meat varies depending on the breeding systems used, influencing its composition in proteins, fats, vitamins, and minerals. Poultry meat is recognized as an affordable source of high-quality protein and other essential nutrients. Intensive, semi-intensive and extensive growth systems cause significant differences in nutrient composition. In intensive systems, meat chickens grow fast, having a higher fat content and a lipid profile dominated by saturated fatty acids. Extensive and semi-intensive systems, including outdoor access and diversified feeding, result in a healthier lipid composition with a higher polyunsaturated fatty acids, especially omega-3. In addition, poultry meat from extensive systems has a higher content of vitamins, such as vitamin E and minerals such as selenium, due to the more natural and diversified diet. Attributes such as low fat content and increased concentration of polyunsaturated fatty acids and antioxidants make the resulting products considered healthier and more ethical. In conclusion, the diversity of breeding systems offers opportunities to improve the nutritional quality of poultry meat, aligning it with consumer preferences and trends for healthy and sustainable products.

The purpose of this study is to optimize the selection plan for production and reproduction traits in the milk-Palas sheep population totally 486 sheep. The selection criterion is represented by an estimate of the global breeding value, calculated based on the BLP method. Among the four traits considered in terms of economic weights, the most important in the selection turned out to be prolificacy (55%), followed by the amount of milk (24%), the amount of fat (12%) and the amount of protein (9%). The greatest genetic progress per generation was obtained in the case of variant 5 (Milk + Fat + Protein + Prolificacy), the genetic gain being 7.6623 kg milk and of 0.0407 lambs/calving. Compared to the control variant (1), the total genetic gain increased by 102.8%. The next variant is variant 2 (Milk + Fat + Prolificacy), which practically ensures a genetic gain similar to variant 5, namely 102.7%. This result is explained by a higher genetic correlation between the amount of milk and the amount of fat (0.836) compared to the value of the correlation between the amount of milk and the amount of protein (0.441).

The ecosystems of the Danube River basin exhibit remarkable biodiversity, housing over 2,000 plant species and more than 5,000 animal species. This places the Danube among Europe's most valuable rivers in terms of aquatic life diversity, with a total of 103 identified species. The Danube is increasingly affected by climate change, impacting the hydrologic cycle and the availability of food and water resources. The effects of climate change are already observable and projected to intensify, notably in increased frequency and intensity of extreme weather events such as heatwaves, drought periods, and floods. In this paper, we aim to present the impact of climate change on economically valuable fish within the Danube River. We have determined the abundance of these species and analyzed the correlation between recorded temperatures and the river's water level. Given the Danube's unique variety of species, we will highlight the importance of protecting and conserving this valuable ecosystem amidst the escalating climate threats.

The presence of smoke when smoking cheeses can have negative effects on the health of consumers. Polycyclic Aromatic Hydrocarbons (PAH) result from pyrolysis processes as well as incomplete combustion without organic sources. The factors that influence the concentration of PAH in cheeses are: temperature, moisture content, type of wood used in the smoking process, origin of the raw material (cow's milk, sheep's milk). The main PAH compound that specifies their presence in food products is benzo[a]pyrene. The interest directed at them is due to the carcinogenic and mutagenic effects they have on human well-being.
