O presente trabalho teve como objetivo identificar o grau de conhecimento dos manipuladores de alimentos de supermercados da região metropolitana de Londrina, com relação a legislação sanitária, e verificar as deficiências práticas na execução destas normativas. Participaram da pesquisa 50 (cinquenta) colaboradores que trabalham nestes estabelecimentos, manipulando diretamente os alimentos e subprodutos de origem animal. A pesquisa foi realizada por meio de questionário, e o método de amostragem foi não probabilístico. Avaliou-se o nível de conhecimento das boas práticas de manipulação e fabricação, segurança alimentar, contaminação microbiológica, contaminação cruzada e intoxicação alimentar. A maioria dos entrevistados não possuíam nenhum tipo de treinamento específico, e os que tinham demoravam mais de seis meses para fazer cursos de atualizações e/ou aperfeiçoamentos. De acordo com os resultados da pesquisa, foi possível concluir que existe uma deficiência dentro dos setores onde há profissionais que manipulam esses alimentos, principalmente sobre as boas práticas de manipulação. Contudo, concluiu-se que ainda é preciso implementar e elevar a fiscalização destes setores para melhorar a segurança e qualidade dos produtos de origem animal.

O uso irracional de medicamentos veterinários: uma análise prospectiva

Background: Environmental enrichment is a promising strategy to improve the welfare of dairy goats and sheep. However, studies in this field remain scattered, and its effects on productivity are unclear. Objectives: To evaluate the effects of environmental enrichment on behavioral, physiological, and productive parameters in dairy goats and sheep. Data sources: Scopus and Web of Science were searched for studies published from 2010 to 2025. Study eligibility criteria: Experimental or observational peer-reviewed studies comparing enriched vs. non-enriched housing in dairy goats or sheep, reporting on welfare or productivity outcomes. Methods: This review followed PRISMA 2020 guidelines and the PICO framework. Two independent reviewers screened and extracted data. Risk of bias was assessed with the SYRCLE tool. Results: Thirteen studies were included, mostly with goats. Physical, sensory, and social enrichments showed benefits for behavior (e.g., activity, fewer stereotypies) and stress physiology. However, results varied by social rank, enrichment type, and physiological stage. Only three studies assessed productive parameters (weight gain in kids/lambs); none evaluated milk yield or quality. Limitations: Most studies had small samples and short durations. No meta-analysis was conducted due to heterogeneity. Conclusions: Environmental enrichment can benefit the welfare of dairy goats and sheep. However, evidence on productivity is scarce. Long-term studies are needed to evaluate its cost-effectiveness and potential impacts on milk yield and reproductive performance.

This study evaluated whether the complexity and temporal dynamics of environmental enrichment during the nursery phase are associated with piglets’ threat-related responses and affective state using a multimodal approach. We combined an Attentional Bias Test (ABT) with bioacoustic measures, Qualitative Behavior Assessment (QBA), and biomarkers (hair cortisol and serum BDNF). In a commercial nursery setting, 675 piglets were allocated to three treatments: UNI (single continuous item: chains), ALT (chains plus an additional object rotated weekly), and SIM (continuous simultaneous provision of multiple objects). A subsample of 32 piglets underwent the ABT (UNI, n = 10; ALT, n = 11; SIM, n = 11). Most ABT measures related to threat-directed attention and space use showed no detectable treatment differences under the present protocol, and feeding latency was affected by stimulus exposure but not by treatment. In contrast, treatments differed in coping-related responses: UNI showed a higher frequency of excretions, ALT showed a longer standing-inactive duration, and SIM showed more escape attempts. Vocalizations were restricted to harsh grunts, with ALT showing longer harsh-grunt duration and higher total vocal output. QBA and biomarkers further differentiated treatments: SIM showed calmer/less tense expressive profiles, whereas UNI showed higher post-exposure hair cortisol and lower serum BDNF than the more complex conditions. Overall, enrichment-related differences were more consistently detected in coping-related behavior, QBA, and biomarkers than in ABT attentional measures, suggesting that enrichment implementation (stable vs. rotational) shapes partially dissociable behavioral and physiological adaptation profiles, and that both more complex strategies showed a more favorable biological profile than UNI.

Dairy farming requires technical tools that assist in decision-making regarding nutritional management, milk quality, and environmental sustainability. This study aimed to evaluate metabolic-nutritional milk indicators as support instruments for Technical Assistance and Rural Extension (TARE) carried out through university extension programs on farms located in the São Francisco do Caramuri community, in the transition zone between the municipalities of Manaus, Rio Preto da Eva, and Itacoatiara, Amazonas. Individual milk samples from 67 dairy cows (Girolando and crossbred) kept in extensive grazing systems were analyzed, as well as buffalo herds assisted by the extension action. Milk urea nitrogen (MUN), protein, fat, and somatic cell count (SCC) levels were determined. Cattle showed an average MUN of 18.54 mg/dL, situated at the upper limit of the reference range (10–18 mg/dL), while buffaloes showed an average of 31.03 mg/dL, indicating a possible imbalance in the dietary protein:energy ratio. Milk protein remained at 3.04% in cattle and 3.09% in buffaloes. Fat averaged 2.03% in cattle and 5.00% in buffaloes. SCC remained below the legal limit in both species. The results allowed for guiding producers on adjusting protein supplementation and continuous monitoring of quality indicators, strengthening evidence-based technical decision-making. It is concluded that the use of laboratory indicators in the context of rural extension contributes to greater nutritional efficiency, environmental sustainability, and qualification of production management in dairy systems.
