Summary: This study aimed to detect and control Clostridium botulinum in Egyptian fish products using natural leaf extracts of Citrus limon, Citrus sinensis, and Citrus unshiu, as well as investigating the application of C. limon in tuna. The antibacterial activity of C. limon leaf extract was also assessed. Results showed variations in the distribution of positive C. botulinum in fish samples from different governorates. All three Citrus extracts exhibited antimicrobial properties, with C. limon being the most effective. The C. limon leaf extract demonstrated high antioxidant and anti-Clostridium powers, suggesting its potential as a natural preservative in fishery products.

Summary: The values of natural mortality (M) play a significant role in stock assessment models and have a strong impact on model outcomes and management advice. Estimating natural mortality is challenging, and there is often limited information available. In this study, we review the evidence used to estimate natural mortality at different ages for the four main stocks of yellowfin tuna. We discuss important factors influencing the estimation, such as age-related variations linked to size, maturity state, or senescence, and identify information gaps. We also assess the historical values of natural mortality used in stock assessments and propose a range of estimates based on approaches discussed in a recent meeting. Furthermore, we recommend future research to improve the estimation of natural mortality.

Summary: The amount of information needed for analytical tasks in population genetics depends on the number of individuals sampled and the genetic markers measured, with different tasks requiring varying numbers of individuals and genetic markers. Real data from sampling locations across the tropical Pacific Ocean were used to assess genetic differences and sample sizes for tasks such as profile testing, stock delineation, and assignment of individuals to stocks in yellowfin tuna populations. Task-specific sample size requirements were determined to help guide the design of molecular ecological surveys for yellowfin tuna.

Summary: This study investigated the changes in antioxidation ability of yellowfin tuna under different salinity environments and found that low salinity may influence the antioxidant function of yellowfin tuna. However, yellowfin tuna juveniles have strong adaptability to a salinity of 29 parts per thousand. Nevertheless, excessive stress may deplete the body's reserves and reduce its resistance.

Summary: In this study, we developed a species-specific mathematical lipid correction method for white muscle tissue of yellowfin tuna. Results showed that lipid extraction significantly influenced d(13)C values, but had minimal effects on d(15)N and d(34)S. Non-linear models provided better fits to the data, indicating an asymptotic relationship between C:N and d(13)C. This study highlights the value of mathematical correction approaches and provides parameter estimates for lipid correction in yellowfin tuna and similar species.

Summary: This study evaluated the presence of Staphylococcus aureus in chicken fillets and investigated the effectiveness of lyophilized seaweed extracts in inhibiting its growth. Among the seaweed extracts tested, Halimeda opuntia (HO) showed significant antibacterial activity against S. aureus. HO extract also exhibited antioxidant properties and had a higher safety threshold for consumption. Furthermore, the study demonstrated that the addition of HO extract effectively reduced S. aureus count in chicken fillets and improved sensory attributes of the meat.

Summary: Spatial variations in tuna population and habitat preference are influenced by large-scale climate fluctuations, such as the Pacific decadal oscillation (PDO) and Atlantic multidecadal oscillation (AMO). The catch per unit effort (CPUE) of Indo-Pacific Ocean yellowfin tuna (YFT) is higher during negative AMO and positive PDO phases. The YFT habitat preference in the tropical Pacific Ocean shows seesaw patterns due to different environmental factors influenced by the PDO phase.

Summary: Fish and fishery products are highly perishable due to their high nutritional value and moisture content, with spoilage caused by microorganisms and chemical reactions such as lipid oxidation. The use of antimicrobials and antioxidants from natural sources can effectively control spoilage and oxidation, extending shelf life and maintaining quality and safety. These natural additives are considered safe and beneficial for preserving FFP.

Summary: The variety of metabolites produced by lactic acid bacteria (LAB) is not well characterized. This study used HPLC-UV/DAD to determine the specific metabolites produced by Lacticaseibacillus rhamnosus, Levilactobacillus brevis, and Lactiplantibacillus plantarum, and investigated their antimicrobial activity against specific food pathogens. The results identified several metabolites with potential antimicrobial properties, which could be used as natural antimicrobial ingredients in the food industry.

Summary: Breast milk from healthy women in Greece was analyzed for the presence of Lactobacillus and Bifidobacterium using realtime PCR. Colostrum samples showed higher percentages of these bacteria compared to mature milk, with higher incidence in younger women, rural areas, and normal BMI individuals. Factors like lactation stage, maternal age, and residential location may influence the bacterial composition of human milk. Realtime PCR has potential for microbiological analysis of breast milk.

Summary: The study analyzed the microbial diversity of ten commercial PDO feta cheese samples from Greece, identifying five phyla, 17 families, 38 genera, and 59 bacterial species. The two geographical regions showed unique microbiota fingerprints, but these were ultimately overlapped by the application of starter cultures. Additionally, two previously unreported Gram-negative bacteria were identified in the rare biosphere of feta cheese samples.

Summary: This study investigated the effect of active modified atmosphere packaging on the quality and shelf-life of gilthead seabream fillets during chill storage. The results showed that the samples with CO2 emitters had slower microbial growth and longer lag phases, leading to extended shelf-life. The use of CO2 emitters also improved the chemical freshness and volatile compounds. The selection of appropriate enzymatic Time Temperature Integrators (TTIs) for shelf-life monitoring was also discussed.

Summary: Convenient cuts of poultry products are highly perishable, but their shelf life can be extended using modified atmosphere packaging (MAP) or edible and biodegradable coatings. This study aimed to model the effect of MAP and active coatings enriched with antimicrobial agents on the microbial growth and shelf life of chicken cuts. The results showed that both MAP and active coatings with citrus extract had a similar effect in extending the shelf life of chicken cuts. The study demonstrates the potential of using MAP or edible coatings to improve the shelf life and commercial value of broiler chicken cuts.

Summary: The study aimed to quantify the effectiveness of high pressure on the inactivation of spoilage microflora and the shelf life extension of European sea bass fillets. Results showed that pressures of 100 MPa can extend the shelf life by 1-5 days, while higher pressures can increase it up to 5-fold depending on the applied pressure and temperature. High pressure treatment combined with vacuum packaging significantly extended the shelf life by 4-12 days compared to aerobically stored products. Moreover, high pressure treatment prevented lipid oxidation during storage.
