Assessment of Sulfite Residues in Shrimp from Moroccan Fisheries: Implications for Food Safety and Regulatory Compliance.
Article in Veterinary sciences, 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
Monitoring chemical residue levels in foods of animal origin is essential to ensure food safety and protect consumer health. Sulfites are commonly used in crustaceans to preserve quality; however, excessive levels may raise public health concerns, particularly for sensitive individuals. This study aimed to assess the compliance of shrimp from offshore and coastal fisheries in Morocco with current regulatory standards. A total of 60 samples were collected and analyzed for residual sulfite levels using the semi-quantitative strip test method. The results showed that sulfite concentrations ranged from 5 to 100 mg/kg in offshore samples, with a mean value of 41 mg/kg. Higher concentrations were observed in coastal samples, with an average of 172 mg/kg. Despite the observed differences between fishing origins, most samples complied with the established regulatory limits. These results support the importance of systematic monitoring programs within the fisheries supply chain to strengthen food safety control and contribute to veterinary public health protection.
