Predictive modeling of Salmonella Thompson growth in unpasteurized liquid egg products.
Article in Animal bioscience, 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
objectiveSalmonella Thompson is a major cause of large-scale foodborne disease outbreaks worldwide; however, research on S. Thompson remains limited. This study investigates the development of a predictive model for the growth of S. Thompson in unpasteurized liquid egg products, such as liquid egg white, liquid egg yolk, and liquid whole egg, to understand the associated health risks.
methodsUnpasteurized liquid egg products, confirmed to be free of Salmonella spp., were inoculated with S. Thompson and incubated at various temperatures. Growth kinetic parameters were estimated using both primary and secondary predictive models, including the Baranyi and Roberts model and second-order polynomial models. The effects of environmental factors on S. Thompson growth were analyzed to establish a comprehensive risk assessment framework.
resultsThe growth curves of S. Thompson exhibited a typical bacterial sigmoidal pattern characteristic of bacterial proliferation, with the Baranyi model providing the best fit for describing the growth kinetics. The secondary model accurately predicted the effect of temperature on growth rate, demonstrating that S. Thompson proliferates rapidly under specific environmental conditions. Model validation indicated high accuracy, confirming the reliability of the developed model for risk assessment applications.
conclusionThe established predictive model enables quantitative assessment of the growth behavior of S. Thompson in unpasteurized liquid egg products. This model can be used in risk assessment and food safety management strategies to mitigate the risk of foodborne pathogen contamination in the food industry.
