Cheese is a globally consumed dairy product, with Europe leading the world in its consumption. Italy, as the third-largest cheese producer within the European Union, plays a crucial role in the sector, particularly through its production of Protected Designation of Origin (P.D.O.) cheeses, including Grana Padano and Parmigiano Reggiano. These hard cheeses are widely utilized in pre-packaged grated cheese products, owing to their broad appeal and recognized quality. While mold is a common and often necessary component in cheese production for the development of flavor and texture, fungal growth can also detrimentally affect the quality of cheese, potentially causing economic losses and posing food safety risks. Some molds are capable of producing mycotoxins, such as ochratoxin A (OTA), a toxic compound that has been identified in cheese. This study aims to quantitatively assess the prevalence of OTA contamination in various pre-packaged grated cheese products using the high-performance liquid chromatography method while also exploring the potential implications for food safety. The results revealed a high incidence of OTA, with 97.6% of the samples tested positive for contamination, ranging from below the limit of detection (<LOD) to 19.15 ng g⁻¹. Among the cheeses tested, the Parmigiano Reggiano brand exhibited the significantly highest average level of OTA contamination (5.06 ± 0.66 ng g⁻¹), followed by pecorino (2.25 ± 0.31 ng g⁻¹), mixed (2.15 ± 0.18 ng g⁻¹), and the Grana Padano cheeses (1.53 ± 0.21 ng g⁻¹). Given the widespread consumption of pre-packaged grated cheese products, these findings underscore the importance of continuous monitoring and risk assessment of cheese products, particularly pre-packaged grated varieties, due to the potential health risks associated with OTA exposure. Further investigations are essential to identify the factors contributing to OTA contamination in cheese and to support the development of regulatory standards to ensure consumer safety.

In this study, we analysed scrapie test results of Hungarian indigenous sheep breeds (Cikta, Tsigai, Dairy Tsigai, Transylvanian Racka, and Hungarian Racka in white and black colour variants) and the endangered Hungarian Merino rams during the period from 2019 to 2023. In Hungary, it is mandatory to perform scrapie testing for every ram intended for breeding. These results were subsequently compared with data from analyses conducted in 2004 and between 2013 and 2015, which served as control samples. The test results were given by the Hungarian Sheep and Goat Breeders’ Association. The employees collected ear cartilage tissue samples during the identification of the lambs using TypiFixTM by Agrobiogen GmBH. We determined the frequencies of alleles, genotypes, and risk groups, and calculated the proportion of each within the studied population. The scrapie test results were evaluated using the SPSS 23 software package and a Chi²-test. Samples were categorised into one of five risk groups (R1 (lowest)–R5 (highest)) based on the degree of resistance observed. In conclusion, we found that there was a significant improvement in scrapie susceptibility for all breeds except the Cikta. However, the potential impact of this improvement on other important traits remains undetermined. Regarding susceptibility to scrapie, the Hungarian Merino is the most resistant group, as 68.8% of the rams in this breed belonged to the R1 risk group, while the Cikta sheep is in the least favourable position, as only 3.3% of the examined individuals belonged to this category.

Archeological evidence shows that dairy farming dates to the early Neolithic era in Europe, the Middle East, Asia, and Africa. Over time, it has evolved from domestication to intensive dairy farms with large, high-tech processing units. Dairy farming has contributed to economic growth, food production, employment, and processing industries. Nonetheless, it has been identified as a major contributor to climate change. This study explores the literature on dairy farming and sustainable development goals (SDGs) to identify current scholarly developments since the formulation and adoption of the SDGs in 2015 and themes for future research. This paper argues that sustainability shortfalls in dairy farming are primarily driven by human processes associated with commercialization and industrialization rather than the animals themselves, although biological emissions remain an inherent factor. Data were analyzed using R package, Excel, NVIVO, and VoS Viewer. A review of the literature showed that dairy farming and its contribution to sustainability has gained more scientific interest since 2015. Moreover, livestock management, feed production and management, stakeholder management, logistics and supply chain management, and waste management are the sources of environmental adversities associated with dairy farming. Notably, these are human processes developed from the commercialization of dairy farming and involve multiple stakeholders across the supply chain. While solutions are embedded within these processes, innovation emerges as a key driver of sustainability and a source of opportunities to strengthen sustainability in the dairy farming sector and achieve SDGs. Sustainability strategies, such as sustainable intensification, multifunctional agriculture, and agro-ecology should be implemented to improve sustainability in the dairy sector. Full article

Nanoarchitectonics influences the properties of objects at micro- and even macro-scales, aiming to develop better structures for protection of product. Although its applications were analyzed in different areas, nanoarchitectonics of food packaging—the focus of this review—has not been discussed, to the best of our knowledge. The (A) structural and (B) functional hierarchy of food packaging is discussed here for the enhancement of protection, extending shelf-life, and preserving the nutritional quality of diverse products including meat, fish, dairy, fruits, vegetables, gelled items, and beverages. Interestingly, the structure and design of packaging for these diverse products often possess similar principles and methods including active packaging, gas permeation control, sensor incorporation, UV/pulsed light processing, and thermal/plasma treatment. Here, nanoarchitechtonics serves as the unifying component, enabling protection against oxidation, light, microbial contamination, temperature, and mechanical actions. Finally, materials are an essential consideration in food packaging, particularly beyond commonly used polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), and polyvinyl chloride (PVC) plastics, with emphasis on biodegradable (polybutylene succinate (PBS), polyvinyl alcohol (PVA), polycaprolactone (PCL), and polybutylene adipate co-terephthalate (PBAT)) as well as green even edible (bio)-materials: polysaccharides (starch, cellulose, pectin, gum, zein, alginate, agar, galactan, ulvan, galactomannan, laccase, chitin, chitosan, hyaluronic acid, etc.). Nanoarchitechnotics design of these materials eventually determines the level of food protection as well as the sustainability of the processes.

Background: On 18 April 2024, the United States Department of Agriculture (USDA) published the first food package changes to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in over a decade, which reduced some food benefits (juice, milk, canned fish, and infant fruits and vegetables) and offered substitutes (cash-value vouchers (CVVs) or cash-value benefits (CVBs) to redeem for fruits and vegetables, cheese, soymilk, or other dairy products). Methods: To assess the impact of the changes on the consumption and redemption of these food groups, a systematic search was conducted, identifying 23 peer-reviewed publications between 2010 and 2024. Results: They revealed significant shifts in consumption after the 2009 food package changes; e.g., a decline in 100% juice intake following reductions in juice allowances. Additionally, the review highlighted that the 2009 WIC food package revision was associated with more fruit and vegetable consumption after the increase in CVV allowance. While including milk alternatives like soy-based beverages or lactose-free milk or cheese may improve redemption rates and WIC program satisfaction, the long-term impacts of these proposed changes remain unknown. No research was identified on the consumption of canned fish. Conclusions: This review contributes to understanding the changes in redemption and consumption after the last WIC food package changes, identifies the knowledge gap about prospective impacts, and recommends that the WIC agencies implement appropriate evaluations to promote health and nutrition among vulnerable populations.

The adoption of the PPWR by the Council of the European Union (EU/2025/40) in 2025 intensifies the regulatory pressure on packaging manufacturers and food producers. This necessitates their adaptation of packaging to the new standards and selection of materials by various sustainability criteria and minimum standards. The legal text places particular emphasis on recyclability and the carbon footprint. The dairy industry holds significant economic importance in the DACH region (Germany, Austria, and Switzerland); this study therefore analyzed and compared the recyclability and carbon footprint of selected product categories and diverse packaging options for butter, yogurt, spreads, curd cheese, and cottage cheese. This study found large differences within the product categories, and also between the assessed countries, due to differing waste management systems (collection, sorting, and recycling) and waste streams. A key finding is the substantial discrepancy in glass packaging, which significantly exceeds the emission values of other packaging systems. In terms of recyclability, glass packaging performs well due to the effectiveness of the recycling systems regarding the future effective PPWR. However, significant variations in recyclability were observed between Germany and Austria for tray and cup materials made of PP and PS. Notably, there is a preference for packaging systems without a cardboard sleeve over those with one. This study provides critical insights into the environmental performance of packaging materials in the dairy sector. It highlights the challenges posed by regulatory changes and the urgent need for region-specific strategies. By identifying key areas for improvement in packaging design and waste management, this work lays the foundation for achieving compliance with the PPWR and advancing the transition toward a circular economy in the DACH region.
