Título: Regulatory harmonization needs for farm-to-fork bacteriophage applications in South American food systems. Autoria: PARRA, B.; BASTÍAS, R.; HIGUERA, G.; ROSALES, I. M.; GALARCE, L.; RIVERA, V.; ALLEL, K.; MARTINS, M. F.; FLOREZ, M. J. V.; JIMÉNEZ, J. N.; ECHEVERRÍA, N.; MARAMBIO, C.; AGUAYO, D.; GONZÁLEZ-ROCHA, G.; VILLAMIL, A.; FRESNO, M.; RIVERA, D. Conteúdo: Bacteriophage-based products are gaining attention as effective tools to reduce harmful germs in food and combat antimicrobial resistance throughout the food production process. However, in South America, their use is still limited because of complicated regulations and inconsistent evidence requirements. This review aims to (i) explore the current scientific and technological landscape of using bacteriophages in South American food systems, (ii) identify main regulatory challenges that impact their classification, approval, and use, and (iii) highlight the need for consistent international guidelines, especially from Codex Alimentarius, to help safely and effectively incorporate phage-based products in food. Research on phage-based products is growing, but it is not consistent across different regions. There are more patents and advancements in biotechnology, but they are limited to certain areas. Although progress is being made, the regulatory frameworks are still unclear, especially when it comes to how these products are classified, labeled, and monitored for safety. To address these gaps, risk-based guidelines are needed. These should define product categories and claims, set safety standards, and include rules for tracking products and monitoring them after they hit the market. Creating a new Codex Alimentarius project on phage-based products could help establish global guidelines that promote safe use, reduce uncertainty in regulations, and improve trade in food markets around the world.

Título: Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis. Autoria: BONJOUR, M. da S.; RINALDI, A. J.; SANTOS, E. G. D. dos; FARIA, G. T. B.; MANHAES, A. M. E. de A.; PEREIRA, J. F.; AUAD, A. M.; OLIVEIRA, M. G. de A.; RAMOS, H. J. de O. Conteúdo: The spittlebug Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) is an important pest of forage grasses in South America, where its nymphs cause pasture damage by feeding on xylem sap and producing a characteristic foam that protects them against environmental stressors. To investigate the molecular basis of this adaptation, we integrated RNA-seq analysis of nymphs with LC–MS/MS proteomics of the Batelli gland, the primary source of foam secretion. De novo assembly of 100,666 unigenes revealed broad functional diversity, with strong representation of detoxification enzymes (CYP450s, GSTs, UGTs, carboxylesterases), transporters and ion pumps, cuticle proteins, and stress- and immunity-related genes. Nearly 16% of loci exhibited alternative splicing, particularly within detoxification, chemosensory and osmoregulatory gene families, highlighting evidence of transcriptomic variability. Signal peptide and secreted protein predictions identified 168 high-confidence candidate secreted proteins, including detoxification enzymes, proteases, structural proteins and immune-related factors, several of which are consistent with antimicrobial and surfactant-related functions. Proteomic profiling of the Batelli gland confirmed 500 proteins, enriched in chaperones, metabolic enzymes, detoxification pathways and osmoregulatory components, with the most abundant proteins corresponding to Hsp70 chaperones, ATP synthases, cuticle proteins and carbonic anhydrases. Together, these results provide an integrative transcriptomic and proteomic overview for M. spectabilis nymphs, highlighting genes and proteins associated with xylem feeding, foam production and responses potentially related to environmental stress tolerance. This comprehensive dataset not only advances the understanding of spittlebug biology but also identifies candidate molecular targets that may inform innovative strategies for controlling nymphal stages and mitigating spittlebug damage in forage systems.

Título: Cheese industry in Brazil: Innovation, regulation and consumer perception. Autoria: COSTA, R. G. B.; SOBRAL, D.; PAULA, J. C. J. de; SIQUEIRA, K. B. Conteúdo: Background: Brazil is among the top five milk producers in the world, producing over 35 billion litres annually, while its cheese industry grew more than 26% between 2017 and 2024. The cheese production sector, combined with innovation, legislative updates and changes in consumer behaviour, highlights the importance of scientific knowledge for both the academic community and the dairy industry. Aim (s): This review synthesises research published between 2016 and 2026 on industrialised Brazilian cheeses, integrating evidence on technological innovation, regulatory changes and consumer perception to identify key trends and research gaps shaping the sector’s scientific and industrial agenda. Methods: A systematic literature search was conducted using scientific bases. Current Brazilian regulations and industry statistics were also analysed to contextualise market and regulatory developments, in addition to research on consumer perception of Brazilian industrial cheeses. Major Findings: Major research trends were identified across all cheese categories reviewed: (i) healthier reformulations, including sodium and fat reduction and incorporation of probiotics, prebiotics and bioactive compounds; (ii) shelf life extension and safety improvement through technologies such as essential oils, high hydrostatic pressure and active packaging. Consumer perception remains culturally positive and strongly linked to sensory appeal, although concerns regarding salt, fat and price continue to affect purchasing behaviour. Scientific or Industrial Implications: The results highlight the importance of technological innovation combined with compliance with regulatory requirements and consumer expectations. The integration of science, industry and consumer behaviour can support the development of healthier, more sustainable and competitive products, strengthening the Brazilian cheese sector.

Título: Produção de leite na Zona da Mata de Minas Gerais. Autoria: HOTT, M. C.; ANDRADE, R. G.; MAGALHAES JUNIOR, W. C. P. de; OLIVEIRA, L. A. A. de; OLIVEIRA, P. S. d'; ROCHA, W. S. D. da; PORFIRIO, R. T. Conteúdo: A mesorregião Zona da Mata, localizada no estado de Minas Gerais, consolidou, economicamente, sua formação histórica ligando-se à expansão da cafeicultura no século XIX, ao crescimento viário, ferroviário e conexões com o Vale do Paraíba, Rio de Janeiro, estruturando-se por meio do comércio e urbanização típicos. O estado de Minas Gerais produziu, em 2023, aproximadamente, 9,42 bilhões de litros de leite, cerca de 26,63% da produção nacional, e a mesorregião Zona da Mata 8,75% da produção mineira, sendo a terceira maior mesorregião produtora do Estado, de acordo com o IBGE. O objetivo deste trabalho foi analisar a produção de leite na região na última década e sua distribuição territorial. A produção leiteira da Zona da Mata se concentra na porção sul da região, onde se localizam municípios de Leopoldina, Muriaé, Lima Duarte, Juiz de Fora e Santa Rita de Ibitipoca. O volume da produção de leite na Zona da Mata cresceu 2,5% nos últimos dez anos. A produtividade média do rebanho leiteiro na mesorregião cresceu 62,4% no período observado, com incremento médio de 5,0% ao ano. Os municípios de Muriaé e Juiz de Fora aumentaram sua produção em 27% e 10%, respectivamente.
