Poland warns of echinococcosis risk as berry and mushroom foraging peaks
Public health authorities in Poland have issued a warning about the rising number of echinococcosis cases recorded between 1 January and 30 June 2026. The disease is caused by larvae of the tapeworms *Echinococcus granulosus* and *E. multilocularis*, whose eggs are shed in the feces of infected foxes and dogs. People can become infected by eating unwashed forest berries, vegetables, water or by handling contaminated material, and symptoms may appear only years after infection.
At the same time, forest‑fruit harvesting is booming. Berry picking in the Kaszuby woods has intensified, prompting the advisory to wash all berries thoroughly before consumption. Mushroom foraging has also surged in late July 2026, with abundant yields reported in the Łódź Voivodeship—including boletes, king boletes, butter mushrooms, chanterelles and dry mushrooms—and in the neighbouring Kujawsko‑Pomorskie region, especially in the Bory Tucholskie and surrounding localities. Authorities have highlighted popular sites such as the Spalski and Pilica forests, Spała, Inowłódz, the area around Zalew Sulejowski, and numerous spots in the Bory Tucholskie.
