Chitosan as a sustainable decontamination strategy against
Article in Veterinary world, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background and Aim: Controlling bacterial contamination on pig carcasses is critical for meat safety and public health within the One Health framework. Materials and Methods: Pig skin samples (25 cm²) were collected from commercial carcasses, inoculated with approximately 5-6 log colony-forming units per square centimeter of the target pathogens or left non-inoculated, and treated by spraying with the respective solutions. Samples were stored at 7 °C for 48 h. Microbial enumeration followed International Organization for Standardization methods for mesophiles (Plate Count Agar, 30 °C/72 h), psychrotrophs (Plate Count Agar, 7 °C/10 days), Enterobacteriaceae (Violet Red Bile Glucose agar), Results: Organic acids provided modest initial reductions (<1 log) in spoilage organisms and mainly bacteriostatic effects against pathogens. Chitosan at 0.5% achieved the strongest reductions, lowering initial mesophilic and psychrotrophic counts by >1 log and maintaining the lowest Conclusion: Chitosan, particularly at 0.5%, exhibited superior, more sustained antimicrobial efficacy against both pathogens and spoilage microbiota on pig skin compared with lactic and citric acids. These findings highlight chitosan as a promising natural, sustainable decontamination agent for pig carcasses, with the potential to enhance compliance with European Union microbiological criteria and support greener meat-processing strategies. Further commercial-scale validation and combination approaches are recommended.
