Modeling the risk of introducing cyst-infected meat pork into the food chain in Benin.
Article in BMC public health, 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
backgroundPoorly cooked pork containing Taenia solium cestode larvae contributes to human cysticercosis, a neglected zoonotic disease. Pork is consumed by a majority of the Benin population, and the cooking of popular dishes may not be sufficient to destroy cestode larvae. This study's aim was to estimate the risk of allowing pork contaminated with Taenia solium cysticerci into the food chain.
methodsA stochastic risk assessment was developed in R to model the risk resulting from the three scenarios leading to contaminated pork being introduced into the food chain. The model was parameterized using official animal health surveillance data, published literature and expert opinion.
resultsThe overall probability of cyst-infected meat pork entering the food chain was estimated at 0.41 (95%Crl 0.34-0.48); from informal abattoirs without meat inspection: 0.16 (95%Crl 0.08-0.22) (scenario 1); from non-detection at inspection in formal abattoirs (scenario 2): 0.24 (95%Crl 0.16-0.35); and 0.007(95%Crl 0.001-0.021) from remaining contamination following partial condemnation of positive carcasses (scenario 3). The total number of cyst-infected meat pork that entered the food chain from 2020 to 2023 was estimated at 89,167 (95%Crl 60,43-115,174).
conclusionThe risk of cyst-infected meat pork entering the food chain is high. In addition to efforts to improve sanitation and pig farming practices, mitigation measures should also reinforce slaughterhouse inspection with tests that are more sensitive.
