Improper stakeholder practices are considered a primary driver of food loss. This study aims to investigate the consequences of pre- and post-harvest practices on extending the shelf life of agro-food products, identifying which practices yield the highest marginal returns for quality. Using Fractional Regression Models (FRM) and Ordinary Least Squares (OLS), the research analyzed data from 343 Egyptian grape farmers and intermediaries. Key findings at the farmer level include significant food loss reductions through drip irrigation (13.9%), avoiding maturity-accelerating chemicals (24%), increased farmer-cultivated area (6.1%), early morning harvesting (8.7%), and improved packing (13.7%), but delayed harvesting increased losses (21.6%). For intermediaries, longer distances to market increased losses by 0.15%, while using proper storage, marketing in the formal markets, and using an appropriate transportation mode reduced losses by 65.9%, 13.8%, and 7.9%, respectively. Furthermore, the interaction between these practices significantly reduced the share of losses. The study emphasizes the need for increased public–private partnerships in agro-food logistics and improved knowledge dissemination through agricultural extension services and agri-cooperatives to achieve sustainable food production and consumption. This framework ensures robust, policy-actionable insights into how stakeholders’ behaviors influence postharvest losses (PHL). The findings can inform policymakers and agribusiness managers in designing cost-efficient strategies for reducing PHL and promoting sustainable food systems. Full article

Artisanal fisheries in southern Chile rely heavily on the Patagonian red octopus (Enteroctopus megalocyathus) as a valuable resource, contributing significantly to local economies. This octopus species accounts for 25–40% of Chilean octopus landings. It is a merobenthic species, characterized by a semelparous life cycle and a long brooding period, and it is distributed along the Pacific and Atlantic coasts of the southern tip of South America, inhabiting holes and crevices in rocky substrates. However, this fishery faces critical challenges to both its ecological sustainability and the food safety of octopus products. The primary fishing method, using hooks, poses a risk to reproductive capacity as it can capture brooding females. Food safety concerns arise from microbial contamination during pre- and post-harvest handling, bioaccumulation of toxins from algal blooms, and the presence of heavy metals in the marine environment. While evisceration effectively reduces the risk of consuming toxins and heavy metals, inadequate hygiene practices and insufficient ice usage throughout the production chain represent significant food safety risks. Chilean fishing Law No. 18892/1989 defines artisanal fishing and establishes territorial use rights in fisheries (TURFs) to promote sustainable extraction of benthic resources. Integrating training programs on post-harvest handling, hygiene practices, and food safety measures into the TURFs framework, along with targeted investments in infrastructure and technical assistance, is crucial to ensure the long-term sustainability of the E. megalocyathus fishery, protect consumer health, and maintain the economic viability and environmental sustainability of this vital resource for local communities.

This mini-review presents common strategies for controlling Salmonella in poultry, addressing combined pre-harvest and post-harvest interventions to create a multi-hurdle approach. The goal is to highlight integrated approaches that enhance overall food safety and sustainability within the poultry industry. Current pre-harvest and post-harvest strategies are discussed, including industry practices and regulatory frameworks. Emphasis is placed on the implementation of biosecurity measures, vaccination, feed management, and environmental control in pre-harvest settings, as well as processing plant interventions such as antimicrobials for carcass decontamination, sanitation, and quality control measures. Pre-harvest strategies that have shown promise include enhanced biosecurity protocols, selective vaccinations for pathogenic Salmonella strains, and advanced feeding regimens. Post-harvest interventions, such as antimicrobial application for decontamination, have improved sanitation practices, and pathogen reduction technologies are also critical in reducing Salmonella prevalence. An integrated approach that combines both pre-harvest and post-harvest measures is essential for an effective Salmonella control program. Implementing a continuum of control strategies for Salmonella in poultry production is vital for ensuring food safety and protecting public health. Collaborative efforts between researchers, industry stakeholders, and policymakers are necessary to address emerging issues and enhance overall effectiveness. Full article

Thanks to its numerous uses in gastronomy, pharmaceuticals, and cosmetics, basil (Ocimum spp.) is one of the most studied and consumed aromatic plants worldwide. However, its commercialization and availability are limited by its short post-harvest shelf-life, primarily due to its strong sensitivity to cold, poor handling, and consequent microbial contamination. This review provides a comprehensive overview of the latest research on pre-harvest techniques that can extend the shelf-life of basil, aiming to offer a practical tool for growers, distributors, retailers, and scientists. In addition to influencing the plant’s primary metabolism, pre-harvest factors, such as genotype selection, plant nutrition, irrigation, and light management, can have a direct impact on basil quality and shelf-life. Unlike previous reviews, which primarily focus on post-harvest strategies, this work provides a structured analysis of pre-harvest factors that directly influence basil’s shelf-life. By integrating recent findings on genotype selection, nutrient management, and environmental conditions, we offer a comprehensive framework to guide future agronomic practices aimed at minimizing post-harvest losses and enhancing product quality.

Plastic covers protect fruits from cracking caused by pre-harvest rains in sweet cherry orchards; however, they can decrease the quality parameters of cherries, such as firmness, titratable acidity, color, and sugar content. This study evaluated the impact of a reflective ground film used for 21 or 34 DBH (days before harvest) in a commercial sweet cherry orchard (cv. Regina) grown under plastic cover in southern Chile. Our study showed that the exposition of cherry trees to the reflective film increased firmness and total soluble solid (TSS) content in fruits at harvest, homogenizing the concentration of sugars in fruits along the tree canopy. Additionally, using reflective film for 21 DBH increased the proportion of fruits greater than 32 mm in the upper canopy and the quantity of mahogany-colored cherries in the lower canopy, compared to trees un-exposed to the reflective film. Concerning fruit condition defects, the results reveal that using the reflective film increased the incidence of cracking in fruits in both the upper and lower zones of the canopy. Furthermore, we found that the incidence of orange skin and pitting in fruits decreased at post-harvest in trees exposed to the reflective film, but depending on the canopy zones. Moreover, fruits of trees exposed to the film for 34 DBH exhibited a higher incidence of browning pedicel post-harvest. Finally, according to our results, the antioxidant activity increased in fruits exposed to the reflective film for 21 DBH. Therefore, we can conclude that using reflective films on sweet cherry orchards can improve and homogenize the maturity parameters and the antioxidant activity of fruits; however, this practice can negatively impact the condition of fruits post-harvest.

Antimicrobial resistance (AMR) in Campylobacter species, particularly C. jejuni and C. coli, poses a significant public health threat. These bacteria, which are commonly found in livestock, poultry, companion animals, and wildlife, are the leading causes of foodborne illnesses, often transmitted through contaminated poultry. Extensive exposure to antibiotics in human and veterinary medicine creates selection pressure, driving resistance through mechanisms such as point mutations, horizontal gene transfer, and efflux pumps. Resistance to fluoroquinolones, macrolides, and tetracyclines complicates treatment and increases the risk of severe infections. Drug-resistant Campylobacter is transmitted to humans via contaminated food, water, and direct contact with animals, highlighting its zoonotic potential. Addressing this challenge requires effective interventions. Pre-harvest strategies like biosecurity and immune-based methods reduce bacterial loads on farms, while post-harvest measures, including carcass decontamination and freezing, limit contamination. Emerging approaches, such as bacteriocins and natural antimicrobials, offer chemical-free alternatives. Integrated, multidisciplinary interventions across the food chain are essential to mitigate AMR transmission and enhance food safety. Sustainable agricultural practices, antimicrobial stewardship, and innovative solutions are critical to curbing Campylobacter resistance and protecting global public health. Our review examines the dynamics of antimicrobial resistance in Campylobacter and presents current strategies to mitigate Campylobacter-related AMR, offering valuable insights for antimicrobial control in the poultry industry.

Durian, often regarded as the “king of fruits”, plays a significant role in Thailand’s economy, with durian production expanding rapidly due to its profitability and high demand in both domestic and international markets. This growth has introduced challenges, particularly for geographic indication (GI)-certified durians like those from Pak Chong, where the unique soil, climate, and cultivation practices contribute to the fruit’s distinctive quality. Maintaining these standards is crucial to preserving GI certification, but farmers face increasing risks related to pests, diseases, climate variability, and cultivation practices. Effective risk management is essential to ensure the quality and sustainability of GI-certified durian production. This study analyzes risks in Pak Chong GI durian cultivation and proposes strategies to mitigate these risks. The House of Risk (HOR) method was used to identify potential risks at various stages of durian cultivation, including planting, maintenance, pre-harvest, harvest, and postharvest, and to recommend proactive mitigation strategies. This case study focuses on Pak Chong GI durian farmers. Thirty-one risk events driven by 17 risk agents were identified throughout the durian cultivation process. Key risk agents included observation of durian tree behavior, physical characteristics of the planting area, irrigation quantity, understanding of nutrient management, soil nutrients, and soil pH. The three most significant mitigation strategies identified were the implementation of targeted training and learning programs, improved data collection and plating progress tracking ability, and investment in advanced cultivation technology. This study analyzes the critical risks in Pak Chong GI-certified durian cultivation and proposes targeted mitigation strategies using the House of Risk (HOR) method. By identifying risks (HOR1) and developing proactive solutions (HOR2) across key cultivation stages, this research offers practical insights to enhance the quality and sustainability of GI-certified durian production. The findings aim to support farmers, policymakers, and stakeholders in preserving the economic and cultural value of Pak Chong durians. Full article

Sustainable agricultural practices are pivotal for environmental preservation and enhancing crop quality. Understanding soil nutrient levels is crucial in determining appropriate fertilizer application in agriculture production systems. In the 2022/23 agricultural season, an experiment that aimed to investigate the spatial distribution of nitrogen (N₂) fixation or absorption in fields cultivated with diverse crops was carried out in Mozambique. Three experimental fields were established, and the following crops were used—maize (local variety), soybean (SAN-BEIB variety), and cotton (ALBAR SZ9314 variety)—each measuring 83.35 m × 30 m. A sampling grid of 13.9 m × 10 m facilitated the collection of 24 composite soil samples per field, consisting of 5 sub-samples within 12 cells, taken at a depth of 0.0–0.20 m before planting and after harvesting, totaling 12 samples per period per field. Laboratory analysis employed the Kjeldahl method to determine total soil nitrogen levels. The Inverse Distance Weighted (IDW) method was used for mapping the spatial total soil nitrogen distribution. The results revealed distinct total soil nitrogen credit and debit patterns. Variations were notable between pre-planting and post-harvest analyses in maize and cotton, showcasing high absorption and minimal fixation. Contrary to expectations, soybeans exhibited high absorption and low fixation, challenging the determination of optimal crop rotation intervals. Quantitative results identified specific total soil nitrogen debit efficiencies of approximately 1692.29 kg ha⁻¹ in cotton and 1081.5 kg ha⁻¹ in maize, respectively, and a credit of 459.215 kg ha⁻¹ in soybeans. Despite discrepancies, this study serves as a foundational platform for future research. As the findings of this study advocate for continued crop rotation practices to bolster soil health and enhance nutrient utilization, it provides the first novel insights into nitrogen dynamics of global key crops in Mozambique, revealing significant variations in nitrogen fixation and absorption across different crop types and fields, which is crucial for informing tailored agricultural practices and soil fertility management strategies.

Forestry operations and climate variability affect hydrologic response and sediment transport. Management of forested catchments under intense forestry activity in areas under climatic stress is critical. This study analyzes the impact of forest operations (thinning and clearcutting) on runoff (Q) and suspended sediment loads (SSL) in three small catchments (named N02, N03 and N04, respectively) in south-central Chile, where rainfall has decreased by 20% since 2010. Using modified double mass curves and piecewise regression, we separated the effects of forest practices and climate. Thinning in N02 initially reduced Q and SSL, with stable Q overtime, while final harvest in N03 and N04 increased Q, although less than expected. SSL surged post-harvest: 3.6 times in N03 and 1.8 times in N04, potentially linked to hillslope instability. Major SSL events contributed over 55% of post-harvest sediment yield in both catchments, with maximum yields reaching 7.2 tons ha⁻¹ yr⁻¹ in N03 and 4.1 tons ha⁻¹ yr⁻¹ in N04. SSL recovered to pre-harvest levels by the third year, except during a rainy year. Management practices likely contributed to lower SSL and faster recovery. These findings improve our understanding of catchment responses to forest practices and climate change, aiding sustainable forest and water resource management. Full article

Ochratoxin A (OTA) is a mycotoxin produced by fungi species belonging to the genera Aspergillus spp. and Penicillium spp. The proliferation of OTA-producing fungal species may occur due to inadequate practices during both the pre-harvest and post-harvest stages of feed. Consequently, poultry species may be exposed to high concentrations of this mycotoxin that can be transferred to animal tissues due to its carry-over, reaching dangerous concentrations in meat and meat products. Therefore, this review aims to propose a comprehensive overview of the effects of OTA on human health, along with data from global studies on the prevalence and concentrations of this mycotoxin in avian feeds, as well as in poultry meat, edible offal, and eggs. Moreover, the review examines significant gross and histopathological lesions in the kidneys and livers of poultry linked to OTA exposure. Finally, the key methods for OTA prevention and decontamination of feed are described. Full article

Excessive application of fertilizers in drip-irrigated wheat production can suppress yields, lower nutrient utilization efficiency, and lead to economic and environmental issues such as nitrogen residues in the soil. Based on a recommended fertilizer application (RF) strategy that takes into account target yield and nutrient requirements, this study explores the responses of wheat plant traits, changes in topsoil and subsoil nutrients, fertilizer utilization, and economic benefits under this strategy. From 2022 to 2023, a field experiment was conducted in a typical oasis spring wheat production area at the northern foot of the Tianshan Mountains in Xinjiang. The treatments included no fertilizer control (CK), the farmer’s conventional practice (FP), recommended fertilizer (RF), RF with nitrogen omission (RF-N), phosphorus omission (RF-P), and potassium omission (RF-K). The results showed that compared with FP, the RF reduced 91 kg N ha⁻¹ (30.3%) and 33 kg P₂O₅ ha⁻¹ (24.8%) in 2022, and 69 kg N ha⁻¹ (23.0%) and 2 kg P₂O₅ ha⁻¹ (1.5%) in 2023. The effect in 2023 was better; RF also decreased the NO₃⁻¹-N residue in the 0–100 cm soil layer by 40.1 kg N ha⁻¹ compared with FP, with no significant difference in wheat grain yield (RF: 5382.9 kg ha⁻¹) or economic benefit (RF: USD 1613.1 ha⁻¹). Furthermore, there were no significant differences between RF and FP in pre-anthesis NP transport or post-anthesis NP accumulation; however, RF significantly increased pre-anthesis potassium transport volume (15.8%) and transport rate (12.5%). RF led to a 16.3% increase in nitrogen utilization efficiency (NUE), while there was no significant difference in phosphorus utilization efficiency (PUE) compared with FP. The fertilizer yield effect for RF was evaluated as N > P > K. Correlation analysis indicated that grain yield was significantly positively correlated with pre-anthesis NPK transport and post-anthesis NP accumulation. It was also positively correlated with organic matter, alkali-hydrolyzed nitrogen, and Olsen-P content in both the topsoil (0–20 cm) and subsoil (20–40 cm), but not with available potassium in the soil. Therefore, conducting soil tests and determining fertilizer recommendations based on the proposed RF method at harvest can reduce fertilizer usage and achieve a balance between the conflicting objectives of environmental protection, increased crop yields, nutrient utilization efficiency, and improved economic benefits in oasis agricultural areas facing excessive fertilizer application.

The Gulf of Mannar, a UNESCO World Biosphere Reserve, faces severe overfishing and habitat degradation threats. In this study, we investigate the pivotal role of ecosystem services in sustaining local livelihoods and overall well-being. By conducting a comprehensive survey of 480 respondents across two districts, we gathered extensive data on demographics, livelihoods, fishing practices, reliance on ecosystem services, and community management participation. The analysis reveals a critical dependence on the Gulf’s resources (income, food security, traditions) with gender disparities (men fish, women in pre-/post-harvest). Still, fishing is only allowed in the 10 km buffer zone (not the core zone). The findings emphasize the promise of community-based strategies, such as Marine Protected Areas and reviving co-management committees, for achieving sustainable fisheries management. However, we also identify gaps, including the need for more nuanced well-being indicators and improved models for community management participation. To address these challenges, we advocate for sustainable fishing practices, tackling social inequities, especially gender disparities in resource access and decision-making, and investing in fishing communities’ healthcare, education, and social safety nets. Promoting alternative livelihoods can alleviate pressure on fish stocks, and empowering local communities through capacity building and community-based management initiatives is crucial for ensuring the long-term sustainability of the Gulf of Mannar ecosystem and the well-being of its dependent communities. This multifaceted approach holds significant promise for balancing ecological health with human prosperity. Full article

This study assessed knowledge, attitudes, and practices related to food hygiene among mothers from Malawi’s rural communities against the WHO Five Keys to Safer Food (WHO-FKSF) and good pre-and post-harvest practices (GPPHPs) as reference points. Five hundred twenty-two mothers from six rural communities across two districts were selected for the survey. The results indicated limited knowledge among participating mothers regarding managing food hazards, including mycotoxins, bacteria, viruses, and parasites (BVPs). A significant proportion (89.5%) of women reported inconsistent or no handwashing with soap after using the toilet. In addition, 48.7% failed to plant with the first good rains, 38.7% neglected to check for moldy cobs during harvesting, 57.4% dried maize on bare soil, and 99.2% bought maize with noticeable mold. Higher education, knowledge, and positive attitudes were associated with enhanced BVP control practices, while larger households and positive attitudes were linked to improved mold/mycotoxin management (p < 0.05). Mothers showed lower (p < 0.05) knowledge and attitude levels regarding molds than BVPs but demonstrated relatively better practices for mold control. A comprehensive education program based on the WHO Five Keys to Safer Foods, tailored to local socio-cultural norms and incorporating mold and mycotoxin management guidelines, is recommended.

Mango (Mangifera indica L.) is a popular fruit grown in tropical and subtropical regions. Mango has a distinctive aroma, flavour, and nutritional properties. Annual global mango production is >50 million tonnes. Major producers of mango include India, Bangladesh, China, Mexico, Pakistan, Indonesia, Brazil, Thailand, and the Philippines, and it is shipped worldwide. Harvested mango fruit are highly perishable, with a short shelf life. Physiological disorders are among the major factors limiting their postharvest quality and shelf life, including when fruit need phytosanitary treatments, such as hot water treatment, vapour heat treatment, and irradiation. This review focuses on problematic physiological disorders of mango flesh, including physiology and biochemistry. It considers factors contributing to the development and/or exacerbation of internal disorders. Improved production practices, including pruning, nutrient application, and irrigation, along with monitoring and managing environmental conditions (viz., temperature, humidity, and vapour pressure deficit), can potentially maintain fruit robustness to better tolerate otherwise stressful postharvest operations. As demand for mangoes on international markets is compromised by internal quality, robust fruit is crucial to maintaining existing and gaining new domestic and export consumer markets. Considering mango quality, a dynamic system, a more holistic approach encompassing pre-, at-, and post-harvest conditions as a continuum is needed to determine fruit predisposition and subsequent management of internal disorders.

The open burning of sugarcane residue is commonly used as a low-cost and fast method during pre-harvest and post-harvest periods. However, this practice releases various pollutants, including dioxins. This study aims to predict polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs or dioxins) emissions using the grey model (GM (1,1)) and to map the annual flux spatial distribution at the provincial level from 2023 to 2028. An annual emission inventory at the provincial level was developed using the activity rate of dry crop residue from national agencies and literature, following the guidelines set by the United Nations Environment Programme (UNEP). Emission distributions from 2016 to 2022 were then mapped. The average PCDD/F emission values show significant variation among the provinces, averaging 309 pg TEQ/year. Spatially, regions with intensive sugarcane production, such as Lampung and East Java consistently show high emissions, often exceeding 400 pg/m². Emissions calculated using the UNEP emission factor tend to be higher compared to other factors, due to its generic nature and lack of regional specificity. Emission predictions using GM (1,1) indicate that North Sumatra is expected to experience a steady increase in PCDD/Fs emissions, whereas South Sumatra and Lampung are projected are projected to see a slight decline. This forecast assumes no changes in regional intervention strategies. Most regions in Java Island show a gradual increase in emissions, except for East Java, which is predicted to have a slight decline from 416 pg/year in 2023 to 397 pg/year in 2028. Additionally, regions such as Gorontalo and parts of East Java are projected to remain ‘hotspots’ with consistently high emissions, highlighting the need for targeted interventions. To address emission hotspots, this study emphasizes the need for cleaner agricultural practices, enhanced enforcement of environmental regulations, and the integration of advanced monitoring technologies to mitigate the environmental and health impacts of PCDD/F emissions in Indonesia. Future studies should consider developing monthly emissions profiles to better account for local agricultural practices and seasonal conditions. The emission data generated in this study, which include both spatial and temporal distributions, are valuable for air quality modeling studies and can help assess the impact of current and future emissions on ambient air quality.
