Environmental drivers of broiler carcass condemnation in humid subtropical regions: an exploratory study on the association of lagged climatic effects Alessandro Silva Lopes, Guilherme Francisco Sobierai Batista, Denise Ortigosa Stolf, Marcel Manente Boiago, Alessandro Cazonatto Galvão, et al. Tropical Animal Health and Production, 2026 Intensive poultry production in humid subtropical agro-ecologies faces unique environmental challenges that compromise carcass quality, welfare, and food security. While climatic influences are recognized, the temporal dimensions of these effects remain largely underexplored. This study quantified the immediate and time-lagged (1–3 months) influences of climatic variables on 12 causes of broiler carcass condemnation in a representative subtropical hub. Longitudinal data (2021–2023) from federally inspected slaughterhouses in Santa Catarina, Brazil, a relevant case study for poultry production within Köppen Cfa and Cfb climate zones, were analyzed using Spearman rank correlation and robust regression models, including Generalized Linear Models (GLM) with a quasibinomial distribution. Total condemnation rates rose from 13.1% in 2021 to 15.5% in 2023, dominated by gastrointestinal contamination (5.0%) and skin lesions (3.5%). Regression analysis revealed that lagged precipitation was a significant predictor for arthritis and cellulitis ( p < 0.05), whereas higher temperatures and heat index reduced rejections for ascites and skin lesions ( p < 0.01). A quasibinomial GLM identified lagged heat index (β = − 0.096, p = 0.051) as a marginal predictor for inflammatory lesions. These findings suggest an association between environmental conditions during the initial stages of rearing and the final carcass quality. The established models offer insights for seasonal management across similar humid subtropical belts to mitigate economic losses and enhance production sustainability.
Citric Pectin–Cordia verbenacea Bioactive Coatings to Preserve Egg Quality Under Non-Refrigerated Conditions Using Machine Learning Approaches Junior Gonçalves Soares, Suélen Serafini, Fernanda Picoli, Denise Nunes Araújo, Marcel Manente Boiago, et al. Foods, 2026 In many developing regions, the lack of a continuous cold chain poses a significant challenge for the preservation of table eggs. This study developed bioactive coatings based on citric pectin enriched with Cordia verbenacea DC aqueous extract to maintain egg quality under non-refrigerated conditions (25 days). A total of 144 fresh eggs were divided into a Control group and five treatment groups with increasing extract concentrations (0% to 100%). Quality was assessed through physical, chemical, and microbiological parameters, supported by principal component analysis (PCA) and random forest (RF) modeling. The results showed that all coated eggs maintained significantly higher Haugh units (classified as Grade B) compared to the control (grade C) (p < 0.05). The microbial load on the shell, a fundamental indicator of sanitary-hygienic conditions, was reduced from 70.0 ± 5.8 CFU/egg in the control to zero in the 100% extract treatment. The RF model achieved 97.06% accuracy in classifying the treatments, identifying microbial load and Haugh unit as the primary predictors of quality. This bioactive coating represents a sustainable and low-cost technology to enhance the shelf life and safety of eggs in markets without refrigeration infrastructure.
