- WHO updated estimates show 277 million illnesses from potentially foodborne invasive parasites from 2000 to 2021, with about 171 million attributable to foodborne transmission.
- The global foodborne burden is approximately 4.89 million DALYs, with the highest contributions from Taenia solium (1.3 million DALYs) and Clonorchis sinensis (0.921 million DALYs), also leading in foodborne deaths.
- Burden is highest in the Americas region due to Chagas disease, followed by Africa where neurocysticercosis-associated epilepsy is major, and burdens have decreased globally except in the Western Pacific region where clonorchiasis is rising.
- The study used data from systematic reviews, GBD studies, and expert judgement, modeled via hierarchical meta-regression and Monte Carlo simulations to estimate incidences, deaths, and DALYs for 14 parasitic diseases.
- Findings highlight significant health impacts of foodborne parasites, with variations by parasite and region, providing a baseline for intervention assessment and targeting high-burden parasites.
