The Ehec bacteria has become more common again after a decline during the pandemic. Last year, 857 cases of infection were detected, 31 percent more than in 2021.
Marie-Louise Danielsson-Tham, professor of food hygiene, believes that one reason is prevailing food trends, e.g. hamburgers that are not cooked through.
Young children and the elderly are most sensitive, but even healthy adults can get bloody diarrhea and damaged kidneys, she says.
Around one in ten people who get infected get kidney damage that can be permanent, she tells SVT Nyheter.
